Section 400-Programming
Choose Channel Numbering when the information transfer rate is 64 kbps, and the channels on the
Introduction
span are used as single channels. For example, specify to CO:
1st interface=channels 1-24
2nd interface=channels 25-49
In ISDN, Layers 1, 2 and 3 represent signaling levels over the D-channel. Layer 1 is the basic hardware

level that controls messages regarding electrical characteristics, such as speed, channel structure, etc.
Configuration
Layer 2 is the "housekeeping" level, containing controls that make sure the messages coincide,
providing sequence and flow control, etc. Layer 3 is the feature level with messages that establish,
maintain, and terminate connections, as well as additional information for different applications, such as
FF1
passing the identity of the calling party, passing terminal compatibility information, allowing the
redirection of calls, etc.
