Viewing the WAN Protocol

You can see which protocol, Standard (PPP) or X.25, is enabled on this interface.

Do not change the current value.

Using Site Manager

See the WAN Protocol parameter on page A-23 for information.

Displaying EIA Signals

You can display Electronic Industries Association (EIA) signals on the serial ports

of Nortel Networks AN

, ARN

™

, ASN

™

, and BN

routers. You can display

request to send (RTS), clear to send (CTS), data send ready (DSR), data terminal

ready (DTR), and data carrier detect (DCD) signals on any serial port including

RS-232-C, RS-422, and V.35 interfaces.

You can display the EIA signals on a specific serial port by using the

show

command of either the Technician Interface (TI) or the BCC.

For information on using show commands with the TI, see Using Technician

Interface Scripts.

For the BCC, use the command

show serial eia-status

. An active signal is

displayed as “H,” an inactive signal is displayed as “L.” An asterisk (*) denotes a

signal whose state has changed since the last time the signal status was reset.

Caution:

Changing the WAN protocol does not reconfigure the interface, and

could disable it. To change the configured WAN protocol, delete and re-create

the WAN circuit. See Configuring and Managing Routers with Site Manager

for instructions.

Note:

Only the true status of the EIA signals at the serial port are displayed,

and they are not interpreted based on the cable type. For cable types other than

straight-through cables, such as crossover cables, you must interpret the

signals.
