Remarks

1.

Enter system view.

2.

Enter T1 interface view.

controller t1 number N/A

3.

Configure a description.

description text

The default is interface name
Interface.

4.

Configure the framing format. frame-format { esf | sf }

The default is esf.

5.

Set the line coding format.

code { ami | b8zs }

The default is b8zs.

6.

Set the cable type.

cable { long | 0db | -7.5db |
-15db | -22.5db | short | 133ft |
266ft | 399ft | 533ft | 655ft }

The default is long 0db.

7.

Set the interframe filling tag

type.

itf type { 7e | ff }

The default is 0x7E.

8.

Set alarm thresholds.

alarm-threshold { ais { level-1 |
level-2 } | lfa { level-1 | level-2 |

level-3 | level-4 } | los
{ pulse-detection | pulse-recovery }

value }

By default:

For LOS alarms, the threshold of

pulse-detection is 176 and the

threshold of pulse-recovery is

22. If the number of pulses
detected during the total length

of 176 pulse detection intervals

is smaller than 22 (the
pulse-recovery threshold), a

LOS alarm occurs.

Both AIS alarm threshold and

LFA alarm threshold are level-1.

9.

Enable loopback and set the
loopback mode.

loopback { local | payload |
remote }

By default, loopback is disabled.

10.

Restore the default settings for

the T1 interface.

By default, a T1 interface is up.

Configuring a BSV interface

A BSV interface can generate basic rate interfaces (BRIs) and digital voice interfaces.

BRI—Has the same logical characteristics as an ISDN BRI but can be used for only voice
transmission. You can configure ISDN parameters on a BRI interface.

Digital voice interface—Can be configured with voice commands. A digital voice interface has two
subinterfaces, which correspond to the two B channels. You cannot configure commands on the
