Appendix B
Norstar Directory Numbers
Norstar is a digital system, capable of carrying two simultaneous voice conversations over a single
station port. These two voice channels are referred to as the B1 and B2 channels. There are times
when you will want to monitor each of the B1 and B2 channels that CallPilot 150 uses. You can do
this by programming a Norstar telephone with Autodial keys for the B1 and B2 extension
numbers.
The following charts can be used to determine the default B1 and B2 Directory Numbers (DN) of
the Norstar Compact and Modular systems.
