4.0 CONFIGURATION The Model 3088 (see figure 1) has two configuration modes, DIP switch and software. Figure 1. Model 3088 (3088/D version shown) DIP switch configuration mode is entered by starting the unit with the DIP switches in any position other than all OFF or all ON. In DIP switch configuration mode, the DIP switch settings are read at system startup and used to configure the unit. Once the unit has started in DIP switch mode it will remain in DIP switch mode, and its settings cannot be changed.
The Model 3088 provides the following parameters for configuring the unit. Parameter Description Password The password used to login to the console. Circuit ID The circuit ID used to identify the unit. Front Panel Switches If the unit is populated with front panel switches, they can be used to start and stop test modes. If they are disabled, however, the front panel switch settings will be ignored. The V.35 interface can request LALs and RDLs using its RRDL and RLAL pins.
Parameter Clock Mode Annex Line Probe Loopback Pattern DSL Error Monitor Maximum Intervals DSL Error Monitor Interval Time Description Controls DSL and serial clock sources. Internal clock mode means the 3088 provides its own clock to both the serial interface and the DSL link. External clock mode means the serial interface provides the clock used for the DSL link. Receive recover clock mode means the DSL link provides the clock to the serial interface. The G.991.2 Annex.
Possible Values Default Value Parameter Description DSL Error Monitor Interval Count DSL Error Monitor Total Intervals DSL Error Monitor Startup Delay The number of errored intervals allowed before restarting the DSL link. 1–255 3 The number of intervals to inspect before disabling the error monitor. 0–255 10 The length, in seconds, to wait after DSL link comes up before enabling the error monitor. 0–255 5 4.
The two sets of DIP switches on the underside of the Model 3088 are referred to as S1 and S2. As shown in figure 3, the orientation of all DIP switches is the same with respect to “ON” and “OFF” positions ON ON 1 2 3 4 5 6 7 8 OFF Figure 3. Close-up of configuration switches (all sets are identical appearance) 4.2 SYSTEM RESET MODE System reset mode is entered by switching all DIP switches to the OFF position and power cycling the unit.
Configuration Reset to Factory Defaults To recover from a forgotten password, the user may reset the unit to its factory configuration. After seeing the “Reset Mode” message, the user should type the ‘*’ key. This will result in a ‘:’ prompt. At the prompt, the user should enter the command reset. This will restore the unit to the factory configuration. The unit can then be restarted with the settings in place. 4.3 DIP SWITCH SETTINGS The 3088 can be configured with DIP switches.

If DTE loops are enabled, then when these pins are asserted, the 3088/C will start a local loopback or a remote loopback. If DTE loops are disabled, these requests will be ignored.
S2-3: Annex A/B Annex A is typically used in North American-like networks, whereas Annex B is typically used in European-like networks. The different annexes specify different PSD (power spectral density) masks because of the difference in T1 and E1 PSDs. S2-3 Annex ON OFF A B S2-2: Line Probe Line probe is a mechanism that determines the highest rate (192K to 2304K) that the DSL link can reliably support. This takes place during training. The DSL rate will be set to the rate that line probe determines.
• Circuit ID: The circuit ID communicated to other units via EOC. EOC (Embedded Operations Channel) is an out-of-band channel specified in the G.991.2 standard for SHDSL. We use standard EOC messages for our remote loopback. The 3088 also supports proprietary EOC messages that allow a 3096RC to configure it. • Clock Mode: The following options are available: – Internal: The 3088 provides the clock to both the serial and DSL interfaces.
• FPSW Settings: What the front panel switches are set to (if the unit is populated with them). • Configuration Mode: Whether the 3088 is configured by DIP switches or software. • DSL Link State: In Progress, Success, Deactivated, or Idle. • DSL Sync State: Out of Sync, Acquiring Sync, In Sync, or Losing Sync. Note DSL Link State vs.
Help Commands The following commands are provided to help the user find the correct command: • help: Lists all the commands that the console recognizes. • system help: Lists all the commands that start with system that the console recognizes. • system set help: Lists all the commands that start with system set that the console recognizes. • system show help: Lists all the commands that start with system show that the console recognizes.
• system set clockmode : Sets the clock mode. Internal clock mode means the 3088 provides the clock to both the DSL and the serial interface. External clock mode means the 3088 uses the serial transmit clock as its DSL transmit clock (V.35 only). Receive recover clock mode means that the 3088 uses the DSL receive clock as its DSL transmit clock and as the serial receive clock. Note X.21 External Clock Mode—The X.

Follow the instructions below to activate RocketLink Plug ‘n’ Play between CO (Model 3096RC and CP (Model 3088) units: • Set the Model 3096RC (CO) to either Internal or External clocking mode as defined by the application. • Set the Model 3088 (CP) to “RocketLink Plug-and-Play CP” by setting S1 and S2 DIP switches in the ON position as described in figure 4.
5.0 INSTALLATION Once the Model 3088 is properly configured, it is ready to connect to the twisted pair interface, to the serial port, and to the power source. This section tells you how to make these connections. 5.1 CONNECTING THE TWISTED PAIR INTERFACE The Model 3088 supports communication between two DTE devices as follows: Using 24 AWG (.5 mm) wire: • up to 32,000 feet (9.7 km) at 192 kbps • up to 18,500 feet (5.6 km) at 2.312 Mbps on Using 26 AWG (.
The RJ-45 connector on the Model 3088’s twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationships are shown in figure 5. \ 3088/D (V.35, female DB-15) 3088/CA (V.35, female DB-25) Figure 5. Model 3088 V.35/X.21 interfaces. 5.2 CONNECTING THE MODEL 3088/CA (V.35) SERIAL INTERFACE Model 3088/CA supports V.35 serial port connections. This section describes how to connect the serial ports to your V.35 equipment. Connecting the Model 3088/CA (V.
Connecting the Model 3088/CA (V.35) to a “DCE” Device The Model 3088/CA provides a V.35 DCE (data circuit terminating equipment) interface on an DB-25 female connector. As a DCE, this interface is designed to connect to DTE equipment, such as a router. However, tail-circuit applications require connection to another DCE equipment, such as a multiplexer. When connecting the V.35 interface of the Model 3088/CA to your DCE device (see figure 7), use a V.35 tail circuit cable.
ment) for connection to DCE such as a modem or multiplexer. When connecting the X.21 interface of the Model 3088/D to your DTE or DCE device, use an X.21 straight-through cable (See figure 8). DSL Span Remote Model 3088) Straight-Through 15-pin D-Sub Cable Router (DTE) OR Mux (DCE) Model 3088/D (DCE or DTE) Figure 8. Connecting the Model 3088/D to X.21 DTE or DCE To change the DCE/DTE orientation from the default position (DCE), you must open the case Model 3088/D case.
The DCE/DTE strap is located on the top side of the 3088/D pc board (See figure 10, below). The arrows on the top of the strap indicate the configuration of the X.21 port (for example, if the DCE arrows are pointing toward the DB-15 connector, the X.21 port is wired as a DCE). Change the DCE/DTE orientation by pulling the strap out of its socket, rotating it 180º, then plugging the strap back into the socket.
6.0 OPERATION Once the Model 3088 is properly configured and installed, it should operate transparently. This sections describes power-up, reading the LED status monitors, and using the built-in loopback test modes. 6.1 POWER-UP To apply power to the Model 3088, first be sure that you have read section 5.4, “Connecting Power” on page 32, and that the unit is connected to the appropriate power source. Power up the unit. 6.
Term (Green) The Term LED glows solid under the following circumstances: • 3088/CA with V.35 interface: If the serial interface has asserted DTR • 3088/D with the X.21 interface: – Configured as DCE: Indicates that the “Control” signals have been asserted. – Configured as DTE: Indicates that the “Indication” signals have been asserted TM/ER (Red) The TM/ER LED is used to indicate that a test mode is in progress or an error has been detected. It blinks once every second while a test mode is starting.

Local Analog Loopback diagram The data received from the serial interface is looped back before going out on the DSL line. Note that this loopback occurs after the pattern generator/BER meter. This means that running a 511 pattern is conjunction with an LAL should result in no error detected by the meter. The data path for the RDL is shown in figure 14.
7.0 REMOTE CONSOLE MANUAL INFORMATION The PC user (near-end) may configure and verify status of the remote 3088 (far-end) via a Remote Console session. The PC user must log onto the 3088 (near-end) unit to establish a remote console session. Once done, the remote 3088 (far-end) appears as a unit which is locally connected through the RS-232 console port. All commands are transmitted over the G.SHDSL link in the EOC channel.
— If 3088 (Far End) already has an active remote console session open, you will see the message Console: Remote console connection request rejected. This can also happen if the remote 3088 (far-end) has an established remote console session with the local 3088 (near-end) which has timed out. 6. Enter the password at the password prompt for the remote console session.
Figure 16 is a screenshot of opening a typical remote console session: Log in to 3088 (Near End) system show status command shows that DSL link is not up remote console command requests a remote console session on 3088 (Far End) Message informs us that the 3088 (Far End) did not respond and a remote console session was not opened system show status command shows that the DSL link state is success remote console command requests a remote console session on 3088 (Far End) Message informs us that we are now

If the remote 3088 (far-end) has received no command within 5 minutes, it automatically terminates the RCS. Once the RCS is terminated, the PC (far-end) can establish a local console session if desired.
3088 (near-end). However the local 3088 (near-end) is unable to receive this message and the local 3088 (near-end) does not know to terminate the RCS. For this reason, the DSL link must be dropped and re-established. At this point, the RCS can be established anew.

8.0 MODEL 3088 SOFTWARE UPGRADE FEATURE The 3088 is software upgradeable through the console port. Software images will be available in Intel Hex file format. The software upgrade feature is available either by powering up the 3088 will all dipswitches set to the “Off” position, or by entering the “system upgrade” command on the command line interface. The software upgrade takes approximately 5 minutes to complete. The 3088 will print ‘.’ to the screen while the software upgrade is in process.
9.0 RESET CONFIGURATION TO FACTORY DEFAULTS The configuration can be reset to factory defaults from the software reset mode. This allows a user to recover from a forgotten password. To reset to the configuration, follow these steps: 1. Power down the unit. 2. Set all DIP switches to the OFF position. 3. Connect a PC to the Console port. 4. Open a VT100 terminal emulator (such as HyperTerminal). Configure the emulator for 19,200 kbps/1 stop bit/no parity/X-ON X-OFF flow control. 5. Power up the unit.
