Instructions
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 add ds1
07A19 and press ENTER.
The DS1 Circuit Pack screen appears. You must enter a specific port
address for the circuit pack.
2. Type two-way CO 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 desti nation.
3. In the Bit Rate field, type 1.544.
This is the standard for T1 lines.
4. In the Line Coding field, type b8zs.
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 esf.
Lucent recommends you use esf whenever your service provider supports
it.
6. In the Signaling Mode field, type robbed-bit.
7. In the Interface Companding field, type mulaw.
