About the Modem Lightning Warning All Motorola devices should be used in environments designed for computers and electronic equipment. In areas susceptible to lightning, take precautions to prevent damage to electronic equipment. Contact your telephone company, or an electronic accessories vendor, for information on lightning protection equipment.
Selecting Programmed Option Sets • Asynchronous and synchronous answering • Asynchronous and synchronous dialing • Leased line with dial restoral operation Four sets of options are stored in nonvolatile memory. If none is appropriate to an application, you can customize an option set, and save it in nonvolatile memory. Refer to Chapter 4, Configuring the Modem, for more information on option sets.
About the Modem In leased line operation, while connected on the dial line, the modem can monitor for LPDA2 commands in the data stream. If the local modem detects an LPDA2 command, the frame that is being processed is aborted. This prevents the remote DTE from processing the command frame as valid data. Refer to Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem Reference Guide, for details.
Baud Rate: 2400, 2743, 3000, 3200, and 3429. Some baud rates do not support all data rates. Carrier Frequency: 1600, 1646, 1800, 1829, 1920, 1959, and 2000 Hz. Some baud rates do not support all carrier frequencies. Modulation: V.34 is a four-dimensional trellis-coded modulation standard that uses precoding and pre-emphasis equalization schemes. Compatibility in V.34 Modulation Mode 326XFAST Series Modems (operating in V.34 Auto modulation mode), are compatible with modems that do not support the V.
About the Modem Remote Configuration Using the local front panel, an NMS, or local-modem AT ACU, you can configure a remote modem.

Overview This chapter explains how to configure the modem, in conjunction with Chapter 3, Getting Started. Read Chapter 3 before continuing. Then select an option: • If the application requires a communications software package, read the section, “Communications Software Package Operating Notes”. • If you have previously installed the 326X in another application, the section “Preparing for Operation” explains how to reinitialize the modem memory so it can be installed in a new application.
What to Select in the Communications Software Package’s Modem Menu List 1) Select Codex 3260 Modem, Motorola 3260 Modem, or another 3260 option from the package’s modem list. Packages that directly support the 326X Series Modem support industry-standard commands and Motorola-enhanced commands, making further configuration unnecessary. 2) If a 3260 option does not appear in the list, contact the software manufacturer for the latest version of the package (which should have such an option).
Direct Operating Mode If you select Mode=Direct (EC/DC OPT’S category): • Speed conversion and flow control are not supported. If the communications package does not support speed detect, change the 326X’s modulation mode to Auto V.32, and after a connection is established, change the communications software rate to match the modem’s connection rate. • If the communications package supports data rates higher than 9.
326XFAST V.34 and 326XFAST-SDC Notes The information in this section applies when operating at the higher DTE rates available with the 326XFAST V.34 and 326XFAST-SDC Series Modems. • If the communications software package supports the higher terminal rates available with these modems, and you want to use the package’s auto dial or auto answer features, set the modem’s DTE Rate (TERMINAL OPT’S category) to that of the package.
Configuration Option Sets This section discusses the modem’s preconfigured option sets, in three parts: • What is an Option Set? • How to Configure an Option Set • Option Set Defaults—326X V.32bis, 326XFAST V.34, and 326XFAST-SDC What is an Option Set? Configuring the Modem Option sets are complete configurations, each tailored for an application and stored in memory. Option sets get the modem working quickly.
Option Set Descriptions—326X V.32bis and V.34 Modems Option Set 1—Async Calls to Central Site Using the AT ACU With Option Set 1, the modem communicates over dial lines using an asynchronous data format. This option set is appropriate for home or office use where you plan to dial, for example, into a central-site computer, minicomputer, an electronic bulletin board, or a personal computer. When you first install the modem, it is set to power up with Option Set 1 as the factory default.
Option Set 4—Async Answering Central Site Without an ACU (Models 3260/ 62/65/67) Option Set 4 satisfies the needs of an asynchronous application where most calls are inbound (see Table 4-1). Configuring the Modem Because calls are received primarily at the central site, the modem is set to answer calls automatically. With DTR=Discon, the local DTE can control the DTR signal.
With this option set, the local and remote modems are configured for SDC operation. The modems default to Fast Call=Lvl3, and use LAPM error correction with modified V.42bis data compression. Enable Option Set 2 in both the local and remote modems, and ensure that Mode (AT SM) is set the same in both modems. * The modem uses the adaptive rate feature in the V.34 Auto modulation mode. This ensures maximum throughput when line quality is poor.
In this option set, the local and remote modems are configured for SDC operation. The modems default to Fast Call=Lvl3, and use LAPM error correction with modified V.42bis data compression. Enable Option Set 4 in both the local and remote modems, and ensure that Mode (AT SM) is set the same in both modems. * Refer to “326X V.32bis and 326XFAST Modem Application Examples” below. If you operate your modems in leased-line mode with Option Set 4, and one modem has software Revision 7.8 or 7.
5) Do not turn off modem power until SAVE COMPLETED! appears.
From the Modem’s Front Panel: 1) Identify the option set that most closely suits the application. The default is 1. 2) Display the option(s) you want to modify using and . For example, to change Max Rate from 2400 to 7200, display Max Rate: 7200. Press . The display flashes three times and the colon changes to an equals sign. The new option is temporarily saved and Max Rate=7200 displays. 3) Step across the Status/Option Sets/Dialing menu by pressing Save Changes=n.

326X V.32bis and 326XFAST Modem Application Examples Configuring the Modem This section provides application examples for each option set, and notes options you may need to change from factory default settings for each option set. For This Type of Application...
Option Set 1—Async Calls to Central Site Using AT ACU Changing Default Configuration Settings Depending on application requirements, you may need to change the following: • Buffer Delay (AT DB, EC/DC OPTS category), when enabled, allows buffered data in the communications link to be effectively transmitted to the other modem before the modems disconnect. Enable this feature if your application does not ensure a complete transfer of data before the modems disconnect.
Option Set 2—Sync Answering Central Site Without ACU Changing Default Configuration Settings Depending on application requirements, you may need to change the following: • In Option Set 2, the default for network timing is Clock=Internal (AT&X, MODULATION OPTS category). It may be necessary to change the timing to external or loopback, depending on the network clocking source. • In Option Set 2, the default for ACU Select=None. If you want an ACU to operate the modem, select an ACU and a data format.
Synchronous Dialing from an IBM AS 400 The modem operates as a synchronous originate modem with the IBM AS 400. Set the modem to Option Set 3—no reconfiguration from this Option Set is necessary. The AS 400 supports switched operation with call origination via a V.25bis compliant call establishment driver.Using Option Set 3 allows it to be driven by APPC/APPN, the bit-synchronous protocol supported by the IBM AS 400.
Option Set 4—Synchronous Leased Line Applications with Dial Restoral (Models 3261/63/66/68) Changing Default Configuration Settings Depending on application requirements, you may change the following options: • The default Restoral setting in Option Set 4 (leased line models) is Auto/FP. When first configuring the modem, set Restoral=Off. This prevents erroneous status errors from displaying while you configure leased line options.

Single Channel Point-to-Point Digital Link Restoral (A/B Switch)—Option Set 2 • With SDC Option Set 2 selected (for Motorola and non-Motorola DSU/CSUs), the DSUs’ restoral configuration should be set to Timing=Internal. • In this case, the 326XFAST-SDC DTE Rate must be set to a constant rate as provided by the network (defaults of 56/64 kbps).
SDC Option Set 3—Sync Dial Only In a typical dial application, a remote terminal dials the host for file transfers. This allows remote users to dial in as needed, with a higher throughput than formerly attainable over the PSTN. Alternately, the DTE and host (Figure 4-3) could be nodal equipment (e.g., X.25 PADs, routers, bridges). In this configuration, the SDC modems are used for remote dial-up branch connectivity. This is useful for remote uploading or downloading data over the PSTN as needed.
Bandwidth On Demand Bandwidth on demand is often required to support sporadic peak loads. With the SDC modem, you can ensure full network availability and performance at low dialup line costs, without having to prioritize users or applications. Figure 4-4 shows a point-to-point digital link with Motorola 35XX DSU/CSUs connecting two routers over a DDS circuit. The SDC modems are also connected directly to the routers.

A Motorola Network Management System (NMS) is shown. This application could apply to any nodal equipment connections (e.g., bridges, routers, or X.25 PADs).
Remote Access Reset Remote access reset enables someone unfamiliar with the AT command set to quickly configure a local modem so that another modem can dial into it. Then you can use the remote modem to configure local modem options.

What is the Attention (AT) Command Set? .................................................. What Role Does Communications Software Play? ..................................
Introduction The 326X Series Modem supports an asynchronous AT Automatic Calling Interface (Auto-Call Unit or ACU), that is compatible with the industry-standard AT command set. AT commands provide a standard modem communications interface, allowing you to configure and operate a modem from an asynchronous terminal or PC keyboard. AT commands define how the modem is configured, how it makes calls, and the test operations the modem performs.
What is the Attention (AT) Command Set? The AT command set is a collection of commands that let you configure a modem directly from an asynchronous terminal or PC keyboard. The characters AT are a prefix to the commands you issue to your modem. When you type AT, you are asking for the modem’s attention. For instance, to disconnect a telephone call, you type AT for attention and H0 for on-hook (hang up).
To enter multiple AT commands on a single command line: Multiple AT commands can be entered on a command line using a single AT prefix. The modem accepts up to 60 characters after the prefix. Spaces are not counted in the length.
Autobaud Feature The modem automatically detects the speed and character format of the following AT commands issued from your DTE: • AT • at • A/ • a/ This means that any AT command you issue to the modem will cause the modem to “Autobaud.” The exception is the lower-case “a/” and upper-case “A/”, from which only speed can be detected. When the a/ or A/ commands are issued, the modem assumes parity to be the same as that of the previous command.
The escape state is entered by sending the escape character three consecutive times. The escape character is selectable as any ASCII character. Its value is stored in S-Register 2, and the default is “+” (decimal 43). To disable escape command detection, set S-Register 2 to a value greater than 127. A guard time is used with the escape sequence.
This section addresses AT commands that do not cross-reference to a front panel option. A/, Re-Execute Last Command Settings: Not applicable Format: A/ This command re-executes the last AT command string issued to the modem, including redialing a telephone number. To re-execute the last command, enter A/ but do not follow this command with . The A/ command may be entered in either uppercase or lowercase characters.
If ATD is issued while the modem is in escape mode or remote configuration, the modem responds with: ERROR NOTE: Any invalid characters inserted into the dial string will be ignored. ATH, Hang Up Settings: 0, Modem hangs up 1, Busy Out the modem Format: ATHn You may hang up the modem after entering the online escape mode by typing ATH or ATH0. Typing ATH1 while in command mode causes the modem to Busy Out until either the ATH command is entered or the key is pressed.
* AT RD, Redial Last Number Settings: 0, 1 Redial last number one time. n (The maximum number of redials allowed is country-specific. See the 326X Series Modem Country-Specific Guide for more details). Format: * AT RDn * You may redial a failed call n times using the AT RD command. The modem redials a call until a successful connection is made, or until the call has been attempted n times. The AT RD command causes the modem to redial the last number dialed.
Display S-Register Value (AT?) Settings: Selected S-Register Format: AT? This command displays the contents of the “selected” S-Register, as stored in volatile memory. The “selected” S-Register is the last S-Register that was accessed using an S-Register command or the ATSn command. The number must be within the S-Register’s specified range. On power-up, S-Register 0 is “selected.” If you try to read the contents of an unused S-Register, the modem displays OK.
S-Register 1—Ring Count Stored in Nonvolatile Memory?: No Status-Only?: Yes Default Setting: 0 Range: 0 to 255 This S-Register counts the number of rings in an incoming telephone call. If the modem is configured to answer (AT AA, or Answer=S0), when S-Register 1’s value equals S-Register 0’s value, the modem answers the call. If no ring is received after a country-specific time (eight to 10 seconds), the counter is reset to 0.
S-Register 5—Backspace Character Stored in Nonvolatile Memory?: No Status-Only?: No Default Setting: 8 Range: 0 to 127 This S-Register determines the decimal value of the backspace character. The default setting, 08, translates to the ASCII (backspace) character. Values greater than 32 (except 127) disable the backspace function.
S-Register 8—Pause Time for Pause Delay Dial Modifiers Stored in Nonvolatile Memory?: Yes Status-Only?: No Default Setting: 2 Range: 0 to 255 (seconds) This S-Register determines how many seconds the modem pauses while dialing when it encounters a K, k, “,”, or < dial modifier. Pause Delay (AT DP) must be set to S8 (AT DP4) to use S-Register 8’s setting. * * This S-Register also determines the time duration of the pause delay for the “,” character when used in an AT command string.
S-Register 11—DTMF Tone Duration Stored in Nonvolatile Memory?: Yes Status-Only?: No Default Setting: 72 Range: 50 to 255 (country-specific) S-Register 11 defines the duration/spacing of tones (in milliseconds) in Dual Tone Multifrequency (DTMF) dialing. This register has no meaning unless the Tone Length option under the DIALING OPT’S is set to S11. Refer to Appendix C, Country-Specific Information, for the ranges supported by each country.
S-Register 25—Delay Before Looking for DTR Stored in Nonvolatile Memory?: Yes Status-Only?: No Default: 5 Range: 0 to 255 (seconds) * When DTR Delay=S25 (AT DT), and AT Form=Sync Data (AT&M) or V25 Form=AsynSync, the modem goes into synchronous data mode after the modem dials asynchronously. S-Register 25 lets you switch from an asynchronous DTE to a synchronous DTE without hanging up.
S-Register 38—Disconnect Buffer Delay Stored in Nonvolatile Memory?: Yes Status-Only?: No Default: 5 Range: 0 to 255 (seconds) S-Register 38 determines how long the modem processes buffered data when a disconnect is initiated. For S-Register 38 to affect the Delay option (AT DB), Delay (EC OPT’S menu) must be set to “Buf or S38” or “Buf & S38.
S-Register 97—Break Signal Duration Stored in Nonvolatile Memory?: Yes Status-Only?: No Default: 0 (represents 1 second) Range: 0 - 39 Break Signal Duration (ms.
S-Register 98—AC Detect Stored in Nonvolatile Memory?: Yes Status-Only?: No Default: 0 Range: 0-1 This S-Register applies to V.32bis and V.34 operating modes. It enables and disables AC Tone Protect, which is part of the modem’s training sequence. S-Register 99—V.32 Training Time Stored in Nonvolatile Memory?: Yes Status-Only?: No Default: 0 Range: 0 to 216* *One unit = 32 baud = 13.5 milliseconds. This S-Register extends part of the V.32 modulation mode training time.

Dial Modifiers for Special Dialing Requirements When entering telephone numbers into modem memory or dialing directly from the modem’s front panel, you can add dial modifiers to telephone numbers. Table A-4 lists the dial modifiers used in AT ACU applications. Table A-4. Dial Modifiers Modifier Function Description W Dial Wait Instructs the modem to stop and wait for a dial tone. If the modem does not detect a dial tone after a specified period, it aborts the w call.
Table A-4. Dial Modifiers (Continued) Configuration Quick-Reference Modifier Function Description @ Quiet Makes the modem look for one or more ringbacks (followed by Answer five seconds of silence) within the delay time specified by Call Timeout. If five seconds of delay silence is detected, the modem continues to dial the string. If the line is busy, the modem hangs up and sends a BUSY message to the DTE.
Result Codes Result codes are responses sent to the terminal by the AT ACU. Result codes may be sent in word form (RsltForm=Verbose or ATV1), numeric form (RsltForm=Numeric or ATV0), or disabled (RsltCode=Disable or ATQ1). When numeric form is selected, the modem issues only a number code. The rate displayed in a CONNECT message depends on the Connect Message option (ACU OPTS menu). If Con Msg=DTE Rate, the DTE-to-modem rate is displayed. If Con Msg=DCE Rate, the modem-to-modem rate is displayed.

Modem/Computer Interface Connections (Continued) EIA/TIA Pin 232-D ITU V.24 12 CI 112 Signal Data Signal Rate Indicator 13 — 110 Signal Quality 14 — — Ext Select Definition CI (112) is passed from modem to terminal, indicating signaling rate. When signal is on, modem operates at 2400 bps or greater. When signal is off, modem operates below 2400 bps. Signal passes from modem to terminal indicating signal quality of telephone line. When signal is on, signal quality is acceptable.
ITU Recommendation V.35 Modem-to-Computer Interface For compatibility with DTEs operating with a V.35 interface, the 326XFASTSDC Series Modem supports an optional ITU Recommendation V.35 Modemto-Computer interface. Connection is made through the modem’s DTE port (see Figure B-1). NOTE: The 326XFAST-SDC Series Modem with a V.35 interface is currently available in the U. S. A. and Canada. Caution The 326XFAST-SDC Series Modem, if ordered with ITU’s V.
ITU Rate V.35 Modem-to-Computer Interface Pinouts The modem’s digital interface conforms to ITU Rate V.35. The modem should be connected to a data terminal with a compatible digital interface (see Table B-1). Table B-2. ITU V.35 Modem/Computer Interface Connections Cabling and Interface Pinouts B-5 Interface Pinouts Pin V.35 Signal Definition 1 Frame Ground Frame (or protective) ground. 2 Transmit Data (A) Digital data transmitted from the local terminal to the remote modem.

This type of interface connects directly to the DTE-type interface provided by Motorola Network Management Systems.
Table B-4 shows a range of data rates and maximum allowable capacitances. The maximum capacitance is a total of the inter-conductor capacitance (between the conductors represented as Cc in Table B-4), and the capacitance between the shield and the conductor (represented as Cs in Table B-4). Table B-4. Maximum Cable Capacitance per Data Rate Data Rate (kbps) 0-20.0 20.0-64.0 64.0-96.0 115.
For example, assume you require a 30-foot cable. You intend to operate your modem at 64.0 kbps. After looking at Table B-4, you determine that the maximum capacitance for the cable is 900 pF. According to the formula above, divide 900 pF by 30 feet. The result is 30 pF per foot: 900 pF 30 ft = 30 pF/ft Motorola recommends you use Motorola cables to attach your 326X modem(s) to DTE(s). Use Table B-5 to select cable(s) for your application.

5) If the transmitted and received messages are different (i.e., character or framing errors), verify the cable length to the limit specified in Table B-4. Reduce the cable length or capacitance of the cable to the theoretical limit and retry the steps listed in this section. (If the same cable length is required, it is recommended that a low capacitance type cable be used.
