Chapter 1: INTRODUCTION 1-14 CSMIM-T1 Hardware Installation Guide
CHAPTER 2 INSTALLING THE CSMIM-T1 2.1 GENERAL This chapter details the installation and set up procedures for the CSMIM-T1. ! CAUTION The CSMIM-T1 is sensitive to static discharge. Follow static safety handling rules and properly wear an antistatic wrist strap.
Chapter 2: INSTALLING THE CSMIM-T1 2.2 LOCATING THE ETHERNET JUMPERS The CSMIM-T1 has a single jumper block that contains two Ethernet jumpers and one Subnet jumper. Figure 2-1 shows the locations and jumper numbers for the Ethernet and Subnet jumpers. Please note that the jumpers are located on the Main Processor Board, not the modem board.
Locating the Ethernet Jumpers 2.2.1 Setting the Ethernet Jumpers The Ethernet jumpers determine how your CSMIM-T1 operates on the network. You can set the jumpers so that the CSMIM-T1 operates on channel A, B, or C. Refer to Figure 2-1 to locate and configure the jumpers. There is a single jumper block, labelled J12, that is used to select both the Ethernet Segment and the Subnet. Pin row A at J12 is used to select the Subnet. Pin rows B and C are used to select Ethernet Channels.
Chapter 2: INSTALLING THE CSMIM-T1 To set the Subnet jumper, refer to Figure 2-1 and configure pin row A of J12 as follows: • Normal Operation (maintain continuity of the backplane: Default): Place a jumper over the center pin and pin 3 in pin row A. • 2.3 Subnet mode: Place a jumper over the center pin and pin 1 in pin row A. NETWORK BYPASS JUMPER The CSMIM-T1 has an internal jumper that is used to select a bypass mode for the T-1 Engine.
Installing the CSMIM-T1 Using Bypass Mode will allow a connection to the network to be maintained even though the system is powered down (or not on-line). If all channels are not being used for modem applications, the DSX1 interface could be used to drop-and-insert the PBX voice channels into the DS1 connection. (In this example, it requires that the PBX have an integral T1-CSU to terminate the network.) ! CAUTION 2.4 In addition to J12 and J24, there are other jumpers on the module.
Chapter 2: INSTALLING THE CSMIM-T1 1. Remove Security Bars from MMAC chassis, and blank plates from desired slots. 2. Holding the CSMIM-T1 by the front panel, or by the edges of the board, align the bottom and top edges of the board with the guide slots. Make sure that both of the edges of the card rest in the guide slots. 3. Slide the CSMIM-T1 (Figure 2-2) into the desired MMAC slots. 4. Firmly press the module connections into the backplane.
Making Connections 2.5 MAKING CONNECTIONS This section describes how to connect the CSMIM-T1 to a console to access the boot commands, and connecting the T-1 interface as well as the Drop and Insert connection. Table 2-1 Maximum Recommended Cable Lengths Line Speed Cable Length (Feet) Allowed Loss T-1 Long Haul D&I Short Haul 57.6 kbps 115.2 kbps 6000 655 100 50 36dB@772 khz 3dB@772 kHz 30 15 NOTE 2.5.
Chapter 2: INSTALLING THE CSMIM-T1 To put the CSMIM-T1 into ROM Monitor mode, press the SET UP button within 30 seconds of powering up. You can also reset and set up the CSMIM-T1 by pressing the SET UP button until the TRAF LED comes ON, release the button and then press it again. This will reboot the module, and it will come up into ROM Monitor mode. NOTES The CSMIM-T1 takes approximately 3 minutes to boot in the ROM Monitor mode, depending on network traffic.
Power-up and Test 2.5.3 Connecting a Drop/Insert Interface The Drop/Insert Interface is used to connect various CSMIM-T1 channels to a local PBX or other equipment. The Drop/Insert Interface port is located on the front panel of the CSMIM-T1. To connect your local equipment to the CSMIM-T1, simply plug the RJ48C connector located on the Drop/Insert Interface Cable into the Drop/Insert Interface port located on the front panel of the CSMIM-T1.
Chapter 2: INSTALLING THE CSMIM-T1 At the monitor prompt on the console, type config and press the Return key. The following appears on the screen: REVISION/CONFIGURATION INFORMATION ROM Software Rev: 0914 Board ID: 42 CPU Type: 486SXLC2 Memory size: 4 Meg Flash size: N/A Board Type: CSMIM-T1 Ethernet Address: 00-80-2D-00-18-B6 EEPROM size: 65504 Flash ID: N/A T1 Unit Identification: XYLOGICS T1-ENGINE 085234 Rev.
Auto-initializing the ROMs 2.7 AUTO-INITIALIZING THE ROMS The CSMIM-T1 is distributed without an IP address or preferred load host (UNIX/IP or MOP) defined in ROM. When the device is booted, the CSMIM-T1 attempts to auto-initialize its ROMs using BOOTP (bootstrap protocol) and RARP (Reverse Address Resolution Protocol). The CSMIM-T1 supports the BOOTP and RARP protocols. The ROMs use these protocols to obtain boot information without requiring any manual set up on the CSMIM-T1.
Chapter 2: INSTALLING THE CSMIM-T1 2.7.1 BOOTP For a successful BOOTP retrieval, a bootpd must be running on a host on the same network as the CSMIM-T1 and must have the appropriate information in the bootptab file. The CSMIM-T1’s BOOTP implementation adheres to rfc 951, rfc1048, and rfc1084. Below is a sample bootptab file entry used to initialize the CSMIM-T1 named terminator. csmimt1default:\ :sm=255.255.255.0:gw=132.245.22.66:\ :hn:vm=auto:to=-18000: terminator: ht=1:ha=00802d004879:ip=132.245.22.
Software Installation Procedures 2.7.2 RARP If the CSMIM-T1 does not receive a successful BOOTP response, it uses RARP to get the boot information. For a successful RARP retrieval, TCP/IP must be running on a host that is on the same network as the CSMIM-T1 and the host’s ARP table must be initialized with the CSMIM-T1’s Internet and Ethernet addresses (see the arp man page, arp -s). The only boot information that RARP provides is the CSMIM-T1’s Internet address.
Chapter 2: INSTALLING THE CSMIM-T1 ! CAUTION If you are loading software for the first time on a new unit, it is not necessary to erase the EEPROM. To do so will erase the EFS Key information, and you will have to reload it manually. If you have not recorded the key information and erase the EEPROM, you will have to call Cabletron Customer Service with your PO number to get a new one. For the reloading procedure, see Section 2.7.3 Reloading the EFS Key.
Software Installation Procedures 2.8.1 Invoking the Console Monitor After the image boots, you can invoke a Console Monitor by pressing the key on the console. At the Console Monitor prompt, entering help or ? displays the available options: • dump (from the CSMIM-T1 to the host and reboots). • help or ? (displays the available options). • info (displays configuration information for the CSMIM-T1). • leds (displays the current front panel LED status). • quit (exit the Console Monitor, e.
Chapter 2: INSTALLING THE CSMIM-T1 2.8.3 Reloading EFS Key Value In the event that the EFS value is lost, follow this procedure to reload the key. This requires Superuser privileges. If you do not have the correct access abilities, contact the Network Administrator for assistance. If you have not stored the key value in a safe place and must contact Cabletron Customer Support, do so before beginning this procedure. 1. Telnet to the module. 2.
CHAPTER 3 ROM MONITOR COMMANDS 3.1 GENERAL This chapter describes the ROM Monitor commands. These commands are accessed through a terminal connected to port 1 when the CSMIM-T1 is in SETUP mode. Pressing the SETUP switch within 3 seconds of powering up puts the CSMIM-T1 into Set Up mode. The ROM Monitor commands allow you to set a number of EEPROM parameters.
Chapter 3: ROM Monitor Commands Table 3-1 addr [-d] boot [-v] [] boot [-l] [] config console-baud erase help (or “?”) image [-d/] ipx [-d] lat_key [-d] mop [-d] net option_key [-d] ping ports [-d] sequence [-d | ] slip [-d] stats [-slip] 3-2 ROM Monitor Command Displays and sets EEPROM values relevant to network addressing, including the CSMIM-T1’s Internet address. Manually boots and loads the CSMIM-T1’s operating code.
Commands 3.2 COMMANDS Following is an explanation of each of the ROM monitor commands, syntax and other usage information. 3.2.1 addr The addr command displays and sets several CSMIM-T1 operating parameters (EEPROM values) relevant to IP network addressing: • Internet address. • Subnet mask. • Broadcast address. • Preferred Load Host address. • Preferred Dump Host address. • Load/Dump Gateway address. • Type of IP Packet encapsulation.
Chapter 3: ROM Monitor Commands The addr command display looks like this: monitor:: addr Enter Internet address []:: 192.9.200.214 Internet address: 192.9.200.214 Enter Subnet mask [255.255.0.0]:: Enter Broadcast address [0.0.0.0]:: 192.9.200.0 Broadcast address: 192.9.200.0 Enter Preferred Load Host address []:: 192.9.200.88 Preferred Load Host address: 192.9.200.88 Enter Preferred Dump Host address [0.0.0.0]:: 192.9.200.88 Preferred Dump Host address: 192.9.200.
Commands do not define a subnet mask, the CSMIM-T1 uses the generic mask for the specified IP address. The Remote Annex tries to boot from a preferred UNIX load host. If you do not define a preferred load host, the CSMIM-T1 broadcasts its load request on the subnet and loads software from the first host that responds. If the part of the IP address containing the network address differs from the preferred load or dump host, that host must be reached through a gateway.
Chapter 3: ROM Monitor Commands NOTES The boot –l command is supported only if the self-boot option (Flash) is installed. Typing the letter q or CONTROL-C interrupts the boot. If you try to boot with a non-existent image file name, the Annex will hang as it searches for the image. You must press the RESET button to recover. A successful boot disables the Console and the ROM monitor. The boot command accepts a file name for the CSMIM-T1’s image.
Commands The status word “! ~XXXX~”, where XXXX are four hexadecimal digits, decodes as follows: 8000 = 4000 = 2000 = 1000 = 800 = 400 = 200 = 100 = 80 = 40 = 20 = 10 = Command complete Chip is busy Command completed without error Command aborted by an abort command Late collision detected Carrier lost CTS lost DMA underrun Transmission deferred because link was busy Collision detected during interframe spacing (SQE/Heartbeat detected) Excessive collisions Reserved The lowest nibble (bits 3 to 0) are a c
Chapter 3: ROM Monitor Commands The next example shows a boot using tftp. The CSMIM-T1 always tries to open a file using bfs first. If unsuccessful, the Remote Annex uses tftp to open the file. monitor:: boot Enter boot file name [(ip) “oper.56.enet”, \ (mop) “OPER_56_ENET.SYS”]:: Requesting default boot file “OPER_56_ENET.SYS” for MOP/VMS\ loads and “oper.56.enet” for all other protocols. Unanswered requests shown as ‘?’,transmission errors as ‘*’. Requesting boot from 192.9.200.88 via Ethernet...
Commands NOTE The boot –l command is supported only if the self-boot option is installed. After executing a boot –l, the ls command may not show the newly-loaded image. The boot –l command display looks like this: monitor:: boot –l Enter boot file name [(ip) “oper.56.enet”, \ (mop) “OPER_56_ENET.SYS”]:: Requesting default boot file “OPER_56_ENET.SYS” for \ MOP/VMS loads and “oper.56.enet” for all other protocols.\ Unanswered requests shown as ‘?’, transmission errors as\ ‘*’. Requesting boot from 192.9.
Chapter 3: ROM Monitor Commands The boot –v command displays the boot in verbose mode. This output includes the turnaround time in milliseconds for each request. This value equals the time lapse between sending the request and receiving the proper reply from the host. When the boot is complete, verbose output includes a display of network statistics: monitor:: boot –v Enter boot file name [(ip) “oper.56.enet”, \ (mop) “OPER_56_ENET.SYS”]:: Requesting default boot file “OPER_56_ENET.
Commands 3.2.3 config The config command displays the CSMIM-T1’s total number of ports, total amount of memory, the ID number, the serial number, the major and minor hardware revision numbers, and the ROM software revision number. The config command display contains information describing whether or not Flash ROM is installed.
Chapter 3: ROM Monitor Commands 3.2.4 console-baud The console-baud command changes the console port’s baud rate. Thus, the console port can interface with any modem to which it is connected. When the baud rate is entered as auto, the CSMIM-T1 detects the baud rate of the incoming line and adjusts its baud rate accordingly. This command provides support for remote troubleshooting.
Commands 2. From the CSMIM-T1 console port: • At the monitor prompt, enter console-baud. • At the Select baud rate prompt, enter the appropriate baud rate or auto. • Connect the modem to the CSMIM-T1’s console port. 3. From the remote site: • Dial into the modem connected to the CSMIM-T1. • Type RETURN until the monitor prompt appears. 3.2.5 erase The erase command erases the contents of non-volatile memory, including the CSMIM-T1’s IP address.
Chapter 3: ROM Monitor Commands If the self-boot option is not installed, the command display looks like this: monitor:: erase Erase all non-volatile EEPROM memory? (y/n) [n]:: y Erasing <16352 or 8160 bytes> of non-volatile memory. Please wait . . . 16K->|Data 0xff . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16K->|Data 0x0 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Initialized checksum record installed The erase command does not erase the Ethernet address.
Commands The image –d command display looks like this: monitor:: image -d Image name: Default (ip): "oper.56.enet" Default (mop): "OPER_56_ENET.SYS" TFTP Load Directory: "" TFTP Dump path/filename: "dump.192.9.200.88" SELF image name: "oper.56.enet" NOTE The SELF image name appears only if the self-boot image is loaded. If the image file name contains more than 16 characters, it is truncated when MOP is attempted. 3.2.
Chapter 3: ROM Monitor Commands The ipx –d command displays the current settings for all of the entries. The command display looks like this: monitor:: ipx -d IPX preferred load file server: "MARS" IPX Frame type: “802.3” IPX dump user name: "SUSANS" IPX dump password: IPX dump path name: "SYS:\user\susans\" 3.2.9 lat_key The lat_key command allows you to set the LAT key from the ROM monitor. NOTE The lat_key command is optional and may be purchased separately.
Commands 3.2.10 mop The mop command sets the MOP load/dump address. This is useful when the loading the CSMIM-T1’s operational image from a VAX VMS load host. The command syntax is: mop [–d] The mop command display looks like this: monitor:: mop Enter preferred MOP load/dump address []:: Load Broadcast Y/N [Y]:: The mop –d command displays the current MOP settings: monitor:: mop -d MOP preferred load/dump address Load Broadcast: Y 3.2.
Chapter 3: ROM Monitor Commands If the unit passes this test, the console displays PASSED. If the CSMIM-T1 fails, the console displays an error message. Failing this test indicates that the CSMIM-T1 failed to communicate with the MicroMMAC. Contact Cabletron Systems Technical Support. 3.2.12 option_key The option_key command loads an option key from the ROM monitor.
Commands The optional npackets entry is the number of packets to transmit. If you specify npackets, then you must also specify a data_size. The ping command display looks something like this: monitor:: ping 132.245.33.69 PING 132.245.33.69: 64 data bytes To exit out of ping either wait for npackets to be transmitted or, at any point, type q. The ping statistics display upon exit. 3.2.
Chapter 3: ROM Monitor Commands monitor:: ports Individual Port Tests (Data and Control Lines) Some important notes: - All Serial Ports (1-7) which are to be tested require a loopback plug in order to pass the Data Line and Control Line loopback tests. WARNING. If there is a device instead of a loopback plug connected to the port being tested, the device will have data transmitted to it and its Control Line toggled.
Commands 3.2.15 sequence The sequence command edits the load/dump interface list. This list determines the order of the network interfaces, and either the local area network (LAN) or the SLIP interface the CSMIM-T1 will use for loading and dumping. The default, net, uses the LAN interface. The list can contain up to four interfaces. If the CSMIM-T1 fails to boot using the first interface, it will try the next, and then the next interface, and then repeat the sequence.
Chapter 3: ROM Monitor Commands If you enter the command with the –d argument, the console displays the current load/dump interface list. You cannot specify both the –d argument and the interface list with the same command. The sequence –d command display looks like this: monitor:: sequence -d Interface sequence: sl12,net Entering a number for a port that has not been configured properly for SLIP causes the Port nn is not configured for SL/IP message to display, where nn is the port number.
Commands Table 3-2 . The slip Command Prompts Prompt Description Allow SLIP on this port Modifies the port’s mode. A y response changes the port to a SLIP interface. An n response changes the port’s mode to CLI. The port is not available as a SLIP interface and the SLIP parameters are ignored. The default is n. Enter local endpoint address Specifies the CSMIM-T1 IP address for this SLIP interface. The CSMIM-T1 boots over the SLIP interface only if this address is set.
Chapter 3: ROM Monitor Commands The slip command automatically sets the number of data bits to 8 for all SLIP interfaces. The number of data bits does not include the start, stop, or parity bits. The slip command display looks like this: monitor:: slip Line number (1-16):: 6 Allow SL/IP on this port? (y/n) [n]:: y Enter local endpoint address [0.0.0.0]:: 192.9.200.214 Local endpoint address: 192.9.200.214 Enter subnet mask [255.255.255.0]:: Constructed new subnet mask. Enter remote endpoint address [0.0.
Commands 3.2.17 stats The stats command displays current network statistics gathered by the ROM. Use stats along with the boot command to help isolate problems. Table 3-3 describes the network statistics displayed by the stats command.
Chapter 3: ROM Monitor Commands Table 3-3 Statistic Bad Types/ Lengths .Network Statistics (Continued) Description The number of unknown packet types if Ethernet IP encapsulation is being used. The number of packets with illegal lengths if IEEE 802.2/802.3 IP encapsulation is being used. Frames Sent The number of frames sent.
CHAPTER 4 CSMIM-T1 PARAMETERS 4.1 GENERAL The CSMIM-T1 comes with software that supports specific commands and parameters for the configuration and administration of the CSMIM-T1 module. These commands cannot be accessed through the console port. You must either telnet into the CSMIM-T1 from another IP address, or you may use the NA utility. Also note that these commands are not available until after the unit has successfully booted.
Chapter 4: CSMIM-T1 Parameters stats -T The stats -T command displays T-1 network interface statistics for the Annex. Table 4-2 describes the arguments for stats -T. The syntax is: stats -T [ current | total | all | interval_set | clear_alarm ] Table 4-2 Arguments for the stats -T Command Argument Description current Displays Extended Super Frame (ESF) statistics for the current fifteen minute interval. The tni_framing parameter must be set to esf (default).
T-1 Commands The information displayed at the beginning of every stats -T command is described in Table 4-3. Table 4-3 Field stats-T Command Information Description Sync When Sync is true, the T-1 engine is detecting frame synchronization. When Sync is false, the T-1 engine has lost frame synchronization and enters the red alarm state. Loss of Signal When Loss of Signal is true, the T-1 engine is not detecting pulses on the T-1 network interface receiver.
Chapter 4: CSMIM-T1 Parameters Table 4-3 Field stats-T Command Information Description Online When illuminated, the T-1 engine is engaged with the network. Otherwise, the T-1 Network Interface and Drop/Insert Interface are isolated from the T-1 engine. Up Time Amount of time the T-1 engine has been up, in hours, minutes, and seconds. The “hours” field is a 16-bit register that can count up to 2700 days (less than 7 years). Serial Number The T-1 engine’s serial number.
T-1 Commands Table 4-3 Field stats-T Command Information Description Errored Seconds An Errored Second is a second with one or more ESF error events; that is, one or more CRC error events or one or more Out of Frame (OOFs). Severely Errored Seconds A Severely Errored Second (SES) is a second with 320 or more CRC error events or one or more OOF error events. Unavailable Seconds Unavailable Seconds (UAS) are a count of one-second intervals during which service is unavailable.
Chapter 4: CSMIM-T1 Parameters The reset internal_modem command resets the specified T-1 modem_set. There is no physical reset button. A modem reset forces the port to be reset. In addition, if the signal protocol is set to wink start or immediate start, a special AT command is sent to the modem to select the dialtone detection mechanism. The modem_reset parameter specifies the individual modem numbers, separated by commas, or a range of numbers separated by a hyphen.
T-1 Commands T1_loopback The superuser T1_loopback command places the T-1 engine into loopback mode. None of the loopback conditions persist through a power down or reboot. A major consideration to those using the T-1 service must be made before using this command since it will completely disrupt the T-1 service. To switch between two different types of loopback, the first loopback must be cancelled before specifying the second loopback.
Chapter 4: CSMIM-T1 Parameters 4.3 T-1 PARAMETERS The CSMIM-T1 software comes with the following new T-1 parameters: Keyword Description alarmsyslog Sets or displays parameter setting as yes or no. These values enable or disable the alarm event syslogs. bypass Sets or displays parameter setting as yes or no. A setting of yes removes the T-1 engine from the network. map Sets or displays mappings for the DS0 channels. ring Sets or displays parameter setting as yes or no.
Parameter Descriptions Keyword Description tni_line_code Sets or displays parameter setting as ami or b8zs. These values represent the line code used on the T1 Network Interface. tni_ones_density Sets or displays the T1 Network Interface ones density setting as on or off. tdi_distance Sets or displays an integer from 0 to 655 that represents the length of the cable from the T1 Drop/Insert Interface to the PBX or other equipment.
Chapter 4: CSMIM-T1 Parameters map This T-1 parameter controls the mapping of the modems to the T1 Drop and Insert Interface (T1DII) and the T1 Network Interface (T1NI) DS0 slots/channels. The modems can be mapped to any unoccupied slot on the T1NI or the T1DII. The T1NI and the T1DII can be mapped to each other on channels that are not occupied by modems. Information flowing between the T1NI and a modem and the T1DII and a modem flows as voice, not data.
Parameter Descriptions sigproto This T-1 parameter is used to specify the inbound and outbound signaling protocols supported by each T-1 channel (DS0). Each channel supports an inbound protocol and an outbound protocol. Both protocols must be specified even if they are the same. If the protocol pair is invalid, it is rejected with an error message. For inbound-only channels, the outbound protocol must be set to none. For outbound-only channels the inbound protocol must be set to none.
Chapter 4: CSMIM-T1 Parameters tni_clock This T-1 parameter sets the clock for the T1 Network Interface. Parameter settings include loop (service provider), local (Annex), external (T1 Drop/Insert Interface). The default setting is loop. tni_esf_fdl This T-1 parameter sets the T-1 facilities data link (FDL) format. The FDL format is used in conjunction with the ESF format and determined by the service provider. The parameter settings include ANSI (ANSI T1.403) and AT&T (AT&T TR54016) standard formats.
Set T-1 Parameters Example tni_ones_density This T-1 parameter is used to defeat the CSMIM-T1 ones density monitor. The T-1 engine has a built in ones density monitor that will provide the network with the correct number of one pulses. The ones density monitor does the following: 1. The monitor does not allow the CSMIM-T1 to transmit more than fifteen consecutive zeros. 2. The monitor ensures that the CSMIM-T1 has at least N ones in every time window of 8X(N+1) bits, where N=1 to 23.

Chapter 4: CSMIM-T1 Parameters 4-16 CSMIM-T1 Hardware Installation Guide
CHAPTER 5 TROUBLESHOOTING PROCEDURES 5.1 GENERAL The CSMIM-T1’s front panel contains a number of LEDs that provide information about normal operations and about problems that occur. Use these LEDs and the ROM Monitor commands to diagnose problems. Figure 5-1 illustrates the CSMIM-T1’s front panel LEDs.
Chapter 5: Troubleshooting Procedures Refer to Table 5-1 for a description of the LEDs located on the front of the CSMIM-T1. Table 5-1 CSMIM-T1 Front Panel LEDs LED(s) Description MODEM CONFIG STATUS These LEDs indicate the number of modems installed (8, 16, or 24). An indicator is green if all the modems in its group are good. An indicator is amber if one modem in its group is bad.
General LED(s) Description NETWORK ALARMS RED - RED alarm indicator is ON during a locally detected carrier failure. During the RED alarm condition, a YELLOW alarm is transmitted across the telephone network. YEL - YELLOW alarm indicator is ON when receiving a YELLOW alarm condition from the telephone network. BLU - BLUE alarm indicator is ON when receiving an unframed, all-ones Alarm Indication Signal (AIS) from the network.
Chapter 5: Troubleshooting Procedures During power-up and booting, it is more difficult to diagnose problems because they can originate in the CSMIM-T1, the network, or the load server host. However, the LEDs provide both a progress report and an error display to assist you in troubleshooting. NOTE 5.2 If an error occurs, save the status of these LEDs. Technical support personnel can use this information to diagnose problems.
Power-Up and Boot Procedures 5.2.1.1 Normal Mode Error-Free Sequence Table 5-2 summarizes the LED display states during error-free power-up in normal mode. The following subsections describe these states. Table 5-2 Normal Mode Error-Free LED States STAT Green ATTN Amber TRAF Green N1: LEDs OK ● ● ● N2: Hardware OK ● ✕ ● Activity Key: ● ✕ ■ ◆ On continuously. Off. Flashing irregularly. Flashing regularly (about 1Hz).
Chapter 5: Troubleshooting Procedures 5.2.1.2 Normal Mode Error Sequence Table 5-3 shows the state of the indicators when an error occurs at various stages of the start-up process. If the CSMIM-T1 fails during the hardware-test state (N2), the error condition is hardware failure NE2. A description of possible causes and solutions for each error condition is in the following paragraphs.
Power-Up and Boot Procedures If you do not know why the CSMIM-T1 booted the wrong image, enter the ROM Monitor mode and issue an image -d command. The command display will list the image file the CSMIM-T1 is trying to load. 5.2.2 SET UP Mode Enter SET UP Mode by pressing the SET UP button located on the CSMIM-T1 front panel. Press this button within 30 seconds of resetting or powering up the device. 5.2.2.
Chapter 5: Troubleshooting Procedures Activity T2: Testing the Hardware During power-up, the CSMIM-T1 runs self-tests that execute diagnostics for the CPU, ROM, EEPROM, FLASH, etc. The TRAF indicator flashes during the tests and after completing the power-up self-tests, the STAT and Ethernet channel indicators remain on. Activity T3: At the Monitor Prompt When the STAT and ATTN indicators are on, the ROM monitor prompt displays on the console terminal. Enter the boot command at the prompt.
BOOT Failures Activity TE2: Hardware Failure The ROM diagnostics detected a CSMIM-T1 hardware problem requiring service. Call Technical Support. Activity TE7: Booted Wrong Image The CSMIM-T1 loaded an inappropriate image. Press the SETUP button for three seconds to reset the device. Following is a list of ways to prevent this problem in the future: • Be sure that you configure the CSMIM-T1 with the appropriate image (oper.46.enet). • Be sure that the image you are booting has the right name.
Chapter 5: Troubleshooting Procedures The CSMIM-T1 requests a boot image from a pre-defined load host or by broadcasting a boot request. When a host responds, the CSMIM-T1 loads its operational image. The CSMIM-T1 requires setting certain configuration parameters. Enter these parameters using the ROM Monitor commands for the initial boot sequence. See Chapter 3 for more information on these commands.
BOOT Failures The error count pinpoints the error that caused the boot failure. For example, if the boot failed during a Read Request due to excessive Expedited Remote Procedure Call (ERPC) layer errors, the Errors from Last ERPC Layer Invocation lists only errors that occurred during the failed Read Request (see Table 5-6). The report does not list errors that occurred during any other Read Request (see Table 5-7) or during the Open Request (see Table 5-8).
Chapter 5: Troubleshooting Procedures Table 5-7 Errors from Last Read Request Error Description Msgs with wrong size The correct host responded to the Read Request, but the data size is incorrect. ERPC layer errors See Table 5-6. Aborts rx’d The host’s BFS transmitted an abort in response to the CSMIM-T1’s Read Request. Run erpcd –D on the host to obtain more information.
BOOT Failures 5.3.2 Correcting CSMIM-T1 Parameters The following parameters must accurately reflect both the CSMIM-T1 and the network environment in which it operates. Verify the CSMIM-T1’s IP address using the addr command. If your network configuration does not support the factory defaults, verify the following parameters using the addr command: • The Broadcast Address • The Subnet Mask.
Chapter 5: Troubleshooting Procedures 5.3.2.1 Load Server Host Not Responding The CSMIM-T1 can boot from one of the following hosts acting as a load server host: • A UNIX host on the network • Another CSMIM-T1 • A VAX VMS load server host • Any host (UNIX or non-UNIX) using tftp. The following subsections discuss troubleshooting for some of these load server hosts. 5.3.2.
BOOT Failures When the CSMIM-T1 boots in test mode, the console displays the load server host’s Internet address, and indicates whether it receives a response to its Open File Request and to any of its Read File Requests. The host’s progress report indicates receipt of any File Server Requests and its responses to such requests. The host displays erpc_return 0 if it successfully receives a request and is sending out an affirmative response.
Chapter 5: Troubleshooting Procedures 5.3.2.4 VAX VMS Load Host on the LAN If the installation was successful and the NCP CIRCUIT SERVICE is enabled, but the CSMIM-T1 still fails to boot, performing the following steps may locate your problem: 1. Make sure that the file CSMIM-T1 OPER_46_ENET.SYS is in the directory MOM$LOAD and the file protection allows reading. 2.
CSMIM-T1 Dumps 5.4 CSMIM-T1 DUMPS The CSMIM-T1 dumps its memory image to a host running load server software when certain software or hardware events occur. Table 5-9 shows the LED states during a dump. NOTE Dump files are generated for use by technical support personnel only. Events that trigger CSMIM-T1 dumps are: • Non-recoverable hardware or software errors. • Software fails to reset the CSMIM-T1’s watchdog timer. • Software fails one or more internal consistency checks.
Chapter 5: Troubleshooting Procedures NOTE Rename any crash dumps that you want to save. The CSMIM-T1 overwrites crash dumps. The assigned name depends on the number of characters per file name that the dump host supports. For hosts supporting file names longer than 14 characters (e.g., BSD hosts), dump files are named dump.addr. The file extension addr is the CSMIM-T1’s IP address. For hosts that limit file names to 14 characters (e.g.
CHAPTER 6 MODEM GUIDE 6.1 GENERAL The CSMIM-T1 uses 24 high performance, error-correcting, V.34 internal modems. They are fully compatible with V.FC (V.Fast Class) modems and offer support for cellular operations. Under optimum conditions, the modems reach a maximum serial-port speed of 115,200 bps. They support V.42bis data compression, and use Hayes Smartmodem AT and V.25bis command sets, with enhancements for maximum flexibility.
Chapter 6: Modem Guide 6.2 FEATURES The modems have the following features: • ITU-T standards: V.21, V.22, V.22bis, V.23, V.32, V.32bis, and V.34 • Compatibility with Rockwell International’s V.FC protocol • Serial-port speeds of up to 115,200 bps • Bell 212A and Bell 103 protocol standards • V.42 error correction, including LAPM and MNP2 through 4 • V.
Using the AT Command Set 6.3 USING THE AT COMMAND SET Each command line must begin with the characters AT (the ATtention code). Both characters of the attention code must be in either upper case or lower case, but you may type the commands in any combination. Type commands after the OK response. The modem ignores spaces between characters. If you make a mistake, press the backspace key (Cntrl-H) and type the correct character. To make a command take effect, press .

Chapter 6: Modem Guide 6.3.3 V.32bis Cellular Connections Using AT Commands The internal V.34 modems may be set up in different ways to operate over a cellular telephone network. The following are typical setups that might be used. • Your modem supports cellular operation from 1200 to 14,400 bps. • MNP Class 10 is not active for connections below 1200 bps. 6.3.3.
Modulation Protocols 6.4 MODULATION PROTOCOLS Using Multi-Protocol Auto-Answer The multi-protocol auto-answer feature allows auto-answer of incoming calls from modems using any of the following protocols: V.34, V.FC, V.32bis, V.32, V.22bis, V.22 (1200 bps only), V.21, V.23 half-duplex, Bell 212A, and Bell 103. NOTE To enable this feature for V.23 half-duplex connections, set :T2 to a value greater than 0. We recommend setting :T2=20 when falling back to a V.23 half-duplex connection. V.34 and V.
Chapter 6: Modem Guide V.32 and V.32bis Protocols The ITU-T V.32 protocol is for full-duplex data transfer over general switched telephone networks at 9,600 and 4,800 bps. V.32 employs echo cancellation and trellis coded modulation. The ITU-T V.32bis specification enhances V.32 by adding 14,400, 12,000, and 7,200 bps speeds and special rate sequences to shorten speed upshifting and downshifting. V.23 Protocol 1,200 Bps Half-Duplex Operation The modem supports one V.
Modulation Protocols V.22 and V.22bis Protocols V.22 protocol is used for 1200 bps and 600 bps full-duplex connections. The version of V.22 your modem supports is Alternative B. V.22bis protocol enhances V.22 by adding 2400 bps full-duplex connections. For V.22 at 600 bps, both modems must be set to 600 bps. NOTE V.21 Protocol V.21 protocol is used for 300 bps full-duplex connections. The features described in this manual apply to V.21 operation except that your modem does not support: • V.
Chapter 6: Modem Guide Bell 103 Protocol Bell 103 protocol is for 300 bps full-duplex connections. The features described in this guide apply to Bell 103 operation except that your modem does not support: • Digital (loop 1A) and analog (V.54 loop 3) loopback. • LAPM connections. NOTE 6.4.1 When your modem establishes a reliable Bell 103 connection, it displays CONNECT 103/REL - MNP. For a normal or direct Bell 103 connection, the message is CONNECT.

Chapter 6: Modem Guide 6.5 ERROR CORRECTION MNP Classes The modem provides MNP Class 10 and supports MNP Class 5 data compression. It is compatible with all MNP products. Its enhanced MNP service is completely transparent to the user. Class 10: Adverse Channel Enhancements (ACE) optimizes performance under poor line conditions. Class 10 continues to provide compatibility with non-MNP modems.
Error Correction Other Classes of MNP MNP Class 2 uses standard asynchronous framing techniques for data transmission and error correction. Because of this protocol overhead, the actual throughput is less than the bps rate of the modem. MNP Class 3 uses synchronous framing techniques. Removing start and stop bits associated with each character prior to transmitting results in a 20% performance increase over Class 2. Thus, actual throughput is greater than the modem’s bps rate.
Chapter 6: Modem Guide 6.6 DIAGNOSTICS The modem’s diagnostic capabilities verify its performance and can isolate the source of a communications problem. If a problem exists, test all components of the communications path, including the data cable and all connectors. NOTE 6.6.1 The modem must be in normal or direct mode for loopback tests. It does not support these tests in Bell 103, V.13, V.21, or V.23 mode. The modem supports all loopback tests 1,200 bps or higher.
Diagnostics 6.6.3 Local Analog Loopback Local Analog Loopback tests the local serial port and the local computer. This test requires you to type a sequence of characters at your computer. The modem then sends these characters back to your computer. You initiate a Local Analog Loopback test by using the &T1 command. Using Commands to Perform a Local Analog Loopback To initiate a Local Analog Loopback: 1. Type: AT&T1 (must be the last command on the line). 2. Type a sequence of characters.
Chapter 6: Modem Guide 6.6.5 Remote Digital Loopback Remote Digital Loopback tests the remote modem port, the telephone line, the local serial and modem ports, and the local computer. This test requires you to type a sequence of characters at your computer. The modem then sends these characters to the remote modem, which echoes them back to your modem. Initiate a Remote Digital Loopback by using the &T6 command.
Diagnostics The operator of the remote system now types a sequence of characters. You do not see any characters on your display while your modem echoes the characters typed by the operator of the remote modem back to the remote computer. The test continues for the time set with register S18. If you do not use register S18, the operator of the remote modem must hang up or call you on another telephone line to tell you when the test is over.
Chapter 6: Modem Guide 6.7 RESULT CODES The modem can display these result codes when it attempts to establish a connection. See also Chapter 7, AT Commands and Registers for descriptions of the commands. 6.7.1 Connection Result Code Tables The tables use the abbreviations: rel (reliable) and non-rel (non reliable). Table 6-6 shows the short and long form result codes, excluding connection result codes whose form depends on the \V, W, and -M commands.

CHAPTER 7 AT COMMANDS AND REGISTERS This chapter contains the following sections: • The Command Set • Entering Commands • Issuing AT Commands at any Speed • Command Descriptions • Register Descriptions 7.1 THE COMMAND SET The modem responds to a superset of Hayes Smartmodem commands. (Additional commands use the prefixes $, %, ), *, -, :, @, and \.) The modem also stores configuration settings in a set of registers.
Chapter 7: AT Commands and Registers 7.1.1.1 Issuing AT Commands at any Speed You can enter AT commands at any supported serial-port speed up to 115,200 bps. Your modem automatically adjusts to the connection and command speeds (autobauds) up to 19,200 bps. Any time after you enter an AT at any speed up to 19,200 bps, you can enter commands at a new serial-port speed. If you enter a command at 38,400, 57,600, or 115,200 bps, the serial port locks at that speed.
Commands %An Auto-Reliable Fallback Character Where n is an integer between 0 and 127 indicating an ASCII character (Default is 0, auto-reliable fallback character disabled). Sets the ASCII character recognized as the auto-reliable fallback character on the answering modem. In auto-reliable mode, when the modem encounters an incoming auto-reliable fallback character from the remote system, it automatically switches to normal mode and passes the character to the serial port.
Chapter 7: AT Commands and Registers %Bn Modem-Port Bps Rate Where n = 75; 300; 600; 1,200; 2,400; 4,800; 7,200; 9,600; 12,000; 14,400; 16,800; 19,200; 21,600; 24,000; 26,400; 28,800 bps. When you enter this locally, the modem-port bps rate is set. Downshifting can still take place. NOTES If %G0 is set, an AT issued locally causes the modem-port speed to match the serial-port speed, regardless of any previous %B setting. If %G1 is set, the modem speed is changed only when you enter a %Bn command.
Commands Setting this command to 1 or 2 restricts the modem to using either MNP 5 Data Compression or V.42bis compression, respectively, or else a non-compression connection results. If the remote modem does not support data compression or has it disabled, the modem can establish a connection without data compression, regardless of the modem’s %C setting. NOTES We recommend disabling bps rate adjust ( \ J0) for the most throughput.
Chapter 7: AT Commands and Registers \Cn Auto-Reliable Buffer \C0 Does not buffer data during link negotiation. Switches to normal or direct mode if no SYN character is detected within 3 seconds. Buffers all data on the answering modem until it receives either 200 non-SYN characters or a SYN character within 3 seconds (this delay is longer for modem speeds 300 or below). If it receives 200 non-SYN characters, the modem switches to normal mode and passes the data through to the serial port.
Commands D Dial Where is a string of up to 98 characters. Do not type < or >.Valid dial string characters are: 0-9, dial modifiers, and for tone dialing A, B, C, D, #, and*. The modem ignores invalid characters. Dial strings longer than 98 characters produce an error message. Dials a telephone number and attempts to establish a connection. The Dial command must be the last one on a command line.
Chapter 7: AT Commands and Registers R T NOTE W NOTE @ 7-8 (Dial a Number in Answer Mode) Must follow the last character in the dial string. Causes the modem to dial in answer mode when calling an originate-only modem. For example: ATD 5551234R . (Tone Dial) Placed anywhere in the dial string, causes the modem to tone dial. For example: ATD T12345 . Tone dial is the default setting.
Commands ! ; $ 7.2.1 M Q (Flash) Inserted between characters in a dial string, causes the modem to go on hook for 1/2-second and then go back off hook, as though you depressed the switch-hook button on your telephone. (Return to Command State After Dialing) Added to the end of a dial string, tells the modem to remain in command state after it dials the digits preceding the semicolon. This allows you to enter dial strings longer than 98 characters.
Chapter 7: AT Commands and Registers U V X Y Z DL (Dial in Direct Mode) Placed anywhere in the dial string, causes the modem to override current operating mode and dial in direct mode for the current connection only. (Dial in LAPM Mode with Fallback to MNP) Placed anywhere in the dial string, causes the modem to override current operating mode and dial in LAPM reliable mode with fallback to MNP for the current connection only.

Sets modem-port flow control to unidirectional XON/XOFF. Sets the flow control method used to pace data between modems during a normal mode connection. When \G1 is set, the modem sends an XOFF character to stop receiving data, and sends an XON character to resume.
Commands *Hn Link Negotiation Speed *H0 *H1 *H2 Link negotiation occurs at the highest supported speed. Link negotiation occurs at 1,200 bps. Link negotiation occurs at 4,800 bps. Sets the connection speed for link negotiation for connections before upshift occurs between two MNP 10 modems. Use *H1 or *H2 to set speed to 1,200 or 4,800 bps, respectively, to facilitate link negotiation over poor phone lines. In I0 I1 I2 I3 Identification Displays the 4-digit modem product code.
Chapter 7: AT Commands and Registers When the modem establishes a reliable connection at speeds between 4,800 and 16,800 bps with bps rate adjust enabled, the serial-port speed adjusts to 9,600 bps. If the connection speed is above 16,800 bps, the serial port adjusts to 19,200 bps. If you set the serial port to the modem's highest rate of 115,200 bps, turn off bps rate adjust to make sure that the serial port stays at 115,200 bps.
Commands NOTE In reliable link connect state, the sender's Break control setting determines how the receiver handles the Break.
Chapter 7: AT Commands and Registers %Ln Speed Matching %L0 %L1 %L2 %L3 %L4 Provides partial speed matching. Enables speed matching. Disables speed matching. Enables V.8 Automode with fallback to ITU-T Automode. Enables V.8 Automode only. Determines whether the modem uses speed matching to establish a connection.

Chapter 7: AT Commands and Registers )Mn Power Level Adjustment for Cellular Telephone Connections )M0 For central site modems: Auto-adjustment (adjusts power level if remote modem is set to )M1). Use for MNP 10 modems that will connect to both cellular telephone and non-cellular telephone site modems. For cell-side cellular modems: Forces power-level adjustment.
Commands \Nn Operating Mode \N0 \N1 \N2 \N3 \N4 \N5 \N6 Sets normal mode. Sets direct mode. Sets reliable mode. Sets auto-reliable mode. Sets LAPM reliable mode. Sets LAPM reliable mode with fallback to normal mode. Sets LAPM reliable mode with fallback to MNP reliable mode. NOTE You can use dial modifiers to set the operating mode for a single call. See the D command description for details. Normal mode (\N0) can communicate with nearly any modem. Error correction does not take place in normal mode.
Chapter 7: AT Commands and Registers NOTE You may not want to use certain other protocols, such as HP Block Mode, with MNP. Such protocols have particular timing requirements that can interfere with MNP’s effectiveness. Auto-reliable mode (\N3) allows the modem to communicate with remote systems which support the MNP or LAPM reliable link and with systems that do not support the reliable link.
Commands Table 7-7 indicates the type of connections, depending on the operating mode. NC indicates No Connection. Where more than one operating mode is in a column, the first mode is for the originating modem and the second mode is for the answering modem. NOTE MNP Extended Services: In the chart, you can use MNP Extended Services for V.42 connections where LAPM appears if both modems are set with -K1 or -K2.
Chapter 7: AT Commands and Registers %On V.23 Equalizer Control %O0 %O1 Disables equalizers in V.23 half-duplex mode. Enables equalizers in V.23 half-duplex mode. Determines if equalizers are set in V.23 half-duplex mode. To avoid transmission errors during V.23 half-duplex connections, equalizer settings must be the same on both modems. -On Serial-Port Parity -O0 -O1 -O2 -O3 -O4 -O5 -O6 -O7 7 data bits, odd parity. 7 data bits, even parity. 7 data bits, mark parity. 7 data bits, space parity.
Commands NOTES 8 -bits and mark parity. The AT sequence cannot be used to match 8-bit data with mark parity. Eight data bits plus mark parity can only be set by the AT-O command. If -O7 is not set, the modem defaults to 8 data bits, no parity. Space parity. The AT sequence cannot be used to match space parity; no parity is set instead. You must enter AT-O3 to set space parity. P Pulse Dial Changes the current dialing mode to pulse. Tone is the default.
Chapter 7: AT Commands and Registers Qn Quiet Q0 Q1 Q2 Enables output of result codes. Disables output of result codes. Disables answer mode result codes only. Determines whether the modem sends result codes and status codes (OK, BUSY, RING, etc.) to your computer. -Qn Fallback Modulation Speeds -Q0 Disables fallback from a V.32bis or V.32 MNP reliable connection to an MNP reliable 2400 or 1,200 bps connection. Enables fallback from a V.32bis or V.
Commands \Q6 NOTE Keeps CTS Off until connection for bi-directional hardware flow control; ignores RTS until connection. Sets the type of flow control used on the serial port. If the serial-port speed is faster than the modem-port speed, data from your computer enter the modem faster than they leave. The modem holds characters in a buffer and sends them out at the slower modem-port bps rate.
Chapter 7: AT Commands and Registers \Q4 enables unidirectional XON/XOFF flow control. The modem serial port generates, but does not respond to, XON/XOFF flow control characters. This setting allows for computers to transmit data that has XON and XOFF data characters. The computer can still be set to respond to XON/XOFF flow control characters sent to it from the modem during serial-port flow control.
Commands NOTE \S &S0 is equivalent to setting \D0. &S1 is equivalent to setting \D3. Read Online Status Displays a list of modem commands and their current settings. This command also displays the active connection type, as well as the elapsed connect time and the telephone number most recently dialed. The \S command displays several screens. Press any key to move to the next screen. To cancel the display, type the line-delete character – or send a Break.
Chapter 7: AT Commands and Registers &T1 makes the modem display the characters on your screen exactly as you type them. The modem must be in normal or direct mode and set to 1200 bps or higher. &T3 allows a remote modem that does not support the ITU-T V.54 standard to perform a Remote Digital Loopback test with your modem. The modem must connect in normal or direct mode and be set to 1200 bps or higher. &T4 allows the modem to respond to a remote caller’s request to enter Remote Digital Loopback mode.
Commands NOTE You do not need to issue %U when bps rate adjust causes the serial-port speed to change during a connection. You must enter AT%U0 when changing from 11-bit characters to 10-bit characters, and from 10-bit to 11-bit. When the serial-port speed is set to 38,400 bps, you cannot change it until you enter an AT%Un or reset it. NOTE To save the configuration even after the modem is reset, also issue either &W or *W. Vn Result Code Form V0 V1 Sends short-form result codes.
Chapter 7: AT Commands and Registers \V5 CONNECT /REL-MNP or CONNECT /REL-LAPM or CONNECT /REL-CELLULAR Displays \V4 plus modulation V.34, V.FC, V.32, or V.22. Determines whether result codes indicate that a reliable link connection is in effect. The W setting determines the contents of the field. Setting -M1 changes the format of the long-form connect result codes.
Commands When X0 is set, CONNECT displays, regardless of W setting. See the section entitled “Result Codes,” for a list of valid connect messages and result codes. %Wn Pulse Digit Command %W0 n pulse digits dialed for each number. %W1 n+1 pulse digits dialed for each number. %W2 10-n pulse digits dialed for each number. For pulse dialing, determines whether the modem dials each number in a dial string n pulses, n+1 pulses, or 10-n pulses. For example, when %W0 is in effect, it dials 6 with 6 pulses.
Chapter 7: AT Commands and Registers Save telephone numbers independently with the \Pn and &Zn= commands. The *W command saves the serial-port speed and parity and the modem-port speed in effect when you enter *W. See also the &W, &Y, and Z commands. Refer to the section entitled “Storing Multiple User Profiles” for details on multiple user profiles. NOTE The &W and *W commands share the same stored configuration area. Issue one of these commands to override the other stored settings.
Commands NOTE The “W” dial modifier causes the modem to wait for dial tone regardless of the X setting. \Xn XON/XOFF Pass-Through \X0 \X1 Processes XON/XOFF flow control characters. Processes XON/XOFF flow control characters and passes them to the local or remote system so that the local or remote device also processes them. Determines whether XON/XOFF flow control characters pass to the remote or local modem.
Chapter 7: AT Commands and Registers Yn is available only during normal and direct connections. NOTES &Yn Y1 must be set on both modems to take effect. Designate Default User Profile Selects user profile n, where n = 0 to 3 (Default is 0). Designates which of four user profiles the modem loads into active configuration at power up, or when DTR drops when &D3 is set. It saves this command immediately after you enter it; you do not have to enter &W or *W.
Registers 7.3 REGISTERS Some registers control a single function. Others control several functions and are bitmapped. We recommend bitmapped registers for reading modem status only; we suggest you use commands to change the modem’s settings. 7.3.1 Commands to Change or Read Registers Change the Value of a Register Sn=x :Tn=x Changes the value of S or :T register “n” to a new value “x”.
Chapter 7: AT Commands and Registers :Tn? Where n is an integer from 0 to 29, indicating a :T register. Displays the contents in decimal form only of register “n”. Register Descriptions S0=n Ring to Auto-Answer On Range: 0 - 255 rings Default: 1 ring (auto-answer enabled) Sets the number of rings required before the modem answers. ATS0=0 disables auto-answer. The modem ignores ring signals for 5 seconds after disconnect.
Registers S4=n Line Feed Character Range: 0 - 127, ASCII decimal Default: 10 (line feed) Sets the character recognized as a line feed. The line feed character follows the carriage return at the end of command lines and result codes. The modem does not store this register with &W; enter *W to save it. S5=n Backspace Character Range: 0 - 32, ASCII decimal Default: 8 (backspace) Sets the character recognized as a backspace. The modem does not store this register with &W; enter *W to save it.
Chapter 7: AT Commands and Registers • Quiet answer when the “@” dial modifier is encountered in a dial string. The modem does not store this register with &W; enter *W to save it. S8=n Pause Time for Dial Delay Range: 0 - 255 seconds Default: 2 seconds Sets the length of time to pause when the modem encounters the pause dial modifier (“,” - comma).

Chapter 7: AT Commands and Registers If you use register S23 to change the parity set automatically or set by -On, the same number of data and stop bits used before the change is retained. For example, if 8 data bits and even parity is set (-O6) and you change register S23 to odd parity, the 8 data bits and 1 parity bit are retained. However, the parity becomes odd instead of even, changing the Serial-Port Parity command setting to -O5.
Registers This command requires 1200 bps or higher operation with %F0%L1 set. Determines how long the modem attempts to establish a V.32, V.22bis, or V.22 connection before attempting to establish a V.21 connection. During this period, the modem sends V.22bis or V.22 carrier. :T2=n Timer for V.21 Mode During Multi-Protocol Answer Where n is an integer from 0 to 255 representing tenths of a second. Default is 0 (V.23 half-duplex disabled).
Chapter 7: AT Commands and Registers When the originating modem is set for V.21 or V.23 operation, :T3 determines how long the modem waits after detecting answer tone before proceeding with the connection. When :T3 is set to 0, the originating modem does not wait for answer tone. :T4=n Timer for Line Turnaround Delay - Carrier On Where n is an integer from 0 to 255 (in increments of 12.5 milliseconds). Default is 20 (250 milliseconds). This command takes effect only during normal mode V.
Registers :T7=n Timer for False Answer Abort Where n is an integer from 0 to 255, representing seconds. Default n=60 seconds; setting :T7=0 disables this timer. This command takes effect only when the modem falls back to a normal mode V.23 half-duplex connection. Sets the amount of time the modem waits before hanging up when it receives no data. If this command is set to a value greater than zero, the timer starts when the modem connects.
Chapter 7: AT Commands and Registers :T11=n Secondary XON Flow Control Character Where n is a decimal from 0 to 255, representing an 8-bit character. Default is F9 hexadecimal (or 249 decimal). Defines the character used for secondary XON flow control on the modem’s serial port. For secondary flow control to take effect, you must set either -F1\Q1 or -F1\Q4. :T12=n Secondary XOFF Flow Control Character Where n is a decimal from 0 to 255, representing an 8-bit character.
