Connecting a modem to an SDI port

Use the following procedure to connect an SDI port directly (no switch box)
to a modem (see Figure 65):
— At the remote end, connect an RS-232 cable to the terminal and to the
modem.
— At the remote end, connect the cable from the modem to an RJ11
telephone jack. (If a cable is required, connect an NT8D46 cable to the
modem and to the RJ11 jack.)
— At the local end, configure the modem:
• If you are using an A0381391 UDS FastTalk modem, follow the
instructions in this document.
• If you are using a different type of modem, follow the
manufacturer's instructions to set the modem for 9600 baud,
autoanswer, dumb mode, command recognition OFF, command
echo OFF.
— At the local end, connect an NT8D95 cable to the SDI port on the I/O
panel in the rear of the module and to the modem.
— At the local end, connect the cable from the modem to an RJ11 telephone
jack. (If a cable is required, connect an NT8D46 cable to the modem and
to the RJ11 jack.)
— To communicate with a CPSI port, switch the cable from the modem to
the port as needed:
• For debugging or monitoring, connect the cable to the active CPU at
J21 on the I/O panel in the rear of the Core/Network Module.
• For patch downloading, connect the cable to the inactive CPU at J21
on the I/O panel in the rear of the Core or Core/Network Module.
