5Plug the other end of the cable into the serial port on the back of the modem.

6At the back of the modem, plug a dedicated telephone line into the RJ-11 port labeled LINE or TELCO.

7Plug the modem into an external power source and turn it on.

8Configure the EMU modem parameters for remote alarm reporting as instructed in “Modem Parameters (Configure and Test Dial-out Alarm Reporting)” on page 3-14.

SHELF MODEM FOR SLIP OPERATION

One or more shelves can be remotely managed by connecting an external modem to the RS-232/RS-485 SLIP port. However, when managed through the SLIP port, each shelf must be assigned a unique IP address (only one shelf is accessed with each dial-up connection). Figure 1-6 on page 1-7show WorldDSL shelves managed by SNMP through SLIP.

Note: See “EMU Jumper Settings” on page 2-1for RS-232/RS-485 SLIP port configuration.

This procedure requires the use of a 25-wire straight-through cable, with a male DB-25 connector on each end of the cable (see Figure 2-8 on page 2-10).

To connect an external modem to the RS-232/RS-485 SLIP port:

Step Action

1Connect one end of the 25-wire cable to the RS-232/RS-485 (SLIP) connector on the EMS shelf.

2Connect the other end of the cable to a standard modem.

3If the modem has configuration switches or jumpers, set the switches or jumpers for factory default operation. Refer to the modem user manual for more information.

4At the back of the modem, plug a dedicated telephone line into the RJ-11 port labeled LINE or TELCO.

5Plug the modem into an external power source and turn it on.
