Setting up digital trunks 

The following example shows a DS1 circuit pack configured for T1 service. The 
circuit pack is supporting a two-way CO trunk group that carries only voice and 
voice-grade data.

To configure a new DS1 circuit pack:

1. Type 

 

and press 

ENTER

.

The 

DS1 Circuit Pack

 screen appears. You must enter a specific port 

address for the circuit pack.

2. Type 

 in the Name field.

Use this name to record useful information such as the type of trunk group 
associated with this circuit pack or its destination.

3. In the Bit Rate field, type 

.

This is the standard for T1 lines.

4. In the Line Coding field, type 

.

Lucent recommends you use b8zs whenever your service provider supports 
it. Since this trunk group only carries voice traffic, you could also use 
ami-zcs without a problem.

5. In the Framing Mode field, type 

.

Lucent recommends you use esf whenever your service provider supports 
it.
