Installing a Modem
You can connect a modem to the CPU serial port to remotely collect history
data and/or SMDR.
To connect a modem:
1. Plug the DIN end of the 8-Pin DIN to Mod-8 Cable (P/N 80893) into the
CPU serial port.
2. Plug one end of the DB25 to Mod-8 Adaptor (P/N 85981) into the cable.
3. Plug the other end of the adaptor into the DB25F connector on the back
of your modem.
4. Following the instructions that came with your modem, connect a trunk
and the modem’s power supply.
To call from a PC at a remote site:
The remote PC must have a modem connected.
The U Slot default communications parameters of the CPU serial
port are 19200 8 N 1 (19200 baud, eight data bits, no parity and 1
stop bit).
1. Using commercially available communications software, dial the phone
number of the trunk connected to the modem at the telephone system
site.
2. To test history, type Shift 1 on the remote PC.
If history doesn’t output correctly, press Ctrl Break on the remote
PC to toggle through the available CPU baud rates.
