Setting the BofL Timeout

The time period between transmissions of BofL packets is 5 seconds by default.

You can change the BofL timeout value on the logical line to any value from 1 to

60 seconds.

See the BofL Timeout parameter on page A-50

for information.

Enabling or Disabling Logical Line Loopback

In logical line (channelized) loopback mode, the router retransmits received data

for specified timeslots only. This proprietary, SNMP-based form of loopback

passes data through the HDLC controller, and therefore only supports HDLC data.

Logical line loopback mode is disabled by default.

You can specify whether or not to initiate logical line loopback mode on the

logical line.

See the Fractional Loopback parameter on page A-51

for information.

Viewing the Configured WAN Protocol

The WAN Protocol parameter indicates which WAN protocol is configured on this

logical line. Do not change the current value.

To change the configured WAN protocol for an interface, delete and then

reconfigure the circuit.

See the WAN Protocol parameter on page A-51

for information.

Setting the HDLC Service Type

The logical line HDLC service is LLC1 by default. LLC1 adds the HDLC address

and control fields as a prefix to the frame. You can change the service to basic

HDLC (Transparent), based on the requirements of the T1 equipment.

You can set the HDLC service for this logical line. See the Service parameter on

page A-51

for information.

Caution:

Changing the WAN protocol does not reconfigure the interface, and

could disable it.
