The default communication protocol settings for the modem port are:

9600 baud

8 data bits

1 stop bit

No parity

Because the modem port receives DSR and CTS signals before transmitting, control lines are required in the cables. The modem port supports no inbound flow control. The port does not turn on and turn off control lines to indicate the input buffer is full.

To connect a modem to a Nortel Ethernet Routing Switch 8600, you can configure the modem port first using another type of connection to the command line interface (CLI) or Nortel Command Line Interface (NNCLI).

PPP modem connection

You can establish a PPP (Point-to-Point Protocol) link over serial asynchronous lines. PC clients use this link to connect remotely to a switch through a standard dial-up modem and the modem DTE port on the primary switch SF/CPU. You must configure the connection on both the remote client PC and the switch. The following figure shows a standard PPP connection to the Nortel Ethernet Routing Switch 8600.
