Wiring charts
Port numbering on the wiring charts
The port number listed on the wiring charts is useful in
tracking down faults during a maintenance session where error
codes appear on the alarm telephone display. Refer to
Alarm
codes on page 548.
The port numbers (for example: XX12) on the Trunk Cartridge
and Station Module wiring charts have two components:
• XX corresponds to the number that appears on the face of
the Expansion Cartridge port that the Trunk Module or
Station Module is connected to.
• digits (for example, 01 or 12) identify an individual port
number associated with that module.
For example :
The code 812 appearing as part of an error message for a Trunk
Module indicates that the problem is with Expansion Cartridge
port #8 and internal port 12. The corresponding Trunk Module
pins on the distribution block are pin 47 (violet-orange) and
pin 22 (orange-violet).
Integrated Communications System (ICS)
In the charts on the following pages, notice that the ICS has
two internal modules, ICS #1 and ICS #2. ICS #1 handles
telephones and auxiliary equipment. ICS #2 handles lines.
B1 and B2 directory numbers
The terms B1 and B2 correspond to channels on Norstar for
transmitting voice and data. Each DN port number has a
B1 DN and a B2 DN. Devices such as the Norstar and
Business Series telephones use only the B1 DN. Other devices
may need both B1 and B2 channels, requiring B1 and B2 DNs.
