How to Configure Layer 1 Features

Cisco IOS Release 12.0(27)S1

Configuring a T1 in SONET Virtural Tributary Mode

Summary Steps:

1. vtg vtg-number t1 t1-line-number channel-group channel-group-number timeslots list-of-timeslots

[speed {56 | 64}]

2. vtg vtg-number t1 t1-line-number framing {esf | sf [hdlc-idle {0x7E | 0xFF}]}

3. vtg vtg-number t1 t1-line-number clock source {internal | line}

Example:

timeslots 1-5, 20-23

Creates a logical channel group for a T1 line from

the STS-1 configuration level.

In vt-15 mode, the range of the t1-line-number

parameter is 1 to 5.

The channel-group keyword defines a logical

channel group to identify the set of timeslots

allocated to this n x DS0 channel in the

channelized T1 line (where n ranges from 1 to 24

DS0 timeslots).

The timeslots keyword creates the combination of

subranges .

The default speed for DS0 timeslots is 64 Kbps.

In this example, the first T1 line is assigned to

logical channel group 15 with channelized

timeslots 1 to 5, and 20 to 23. The DS0 speed per

timeslot is 64 Kbps.
