Installing a Modem
You can connect a modem to the system's serial port to remotely collect
history data and/or SMDR.
To connect a modem:
1. Plug one end of a mod-8 (standard 8 conductor) patch cord into the sys-
tem's RS-232 port.
2. Plug the other end of the mod-8 patch cord into the DB25 to Mod-8
Adaptor (P/N 85981).
3. Plug the other end of the adaptor into the DB25F connector on the back
of your modem.
The default communications parameters of the system's serial port
are 19200 8 N 1 (19200 baud, eight data bits, no parity and 1 stop
bit).
If you have a PC connected to collect history data, press Shift 1 to
turn history on and off.
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. Also, the default
communications parameters of the system's 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.
