Call Detail Recording
Call Detail Recording can be activated for calls on a personal CO line, but the 
CDR record does not specifically identify the call as PCOL. Calls over personal 
CO lines can, however, be identified by the trunk access code used on the call. The 
call is recorded to the extension number assigned to the phone where the call was...

Setting up digital trunks
Any of the common trunks, except for PCOL trunks, can be analog or digital. 
(PCOL trunks can only be analog.) Administering a digital trunk group is very 
similar to administering its analog counterpart, but digital trunks must connect to a 
DS1 circuit pack and this circuit pack must be administered separately. The 
example in this section shows...

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:

add ds1 07A19 and press ENTER.
The DS1 Circuit Pack
 screen appears. You must enter a specific port 
address for the circuit pack.

T1 recommended settings
The table below shows recommended settings for standard T1 connections to your 
local exchange carrier.
If you use b8zs line coding and esf framing, it will be easier to upgrade your T1 
facility to ISDN should you want to. You can upgrade without reconfiguring 
external channel service units, and your service provider won’t have to...
