Setting up the ICS
P0873832 Issue 05
Program the ICS for the CTA 500dm the same way that you program
the ICS for a Norstar set. You can program line access, line pool
codes and restrictions to apply to outgoing calls. The CTA 500dm
must be assigned to a digital line or to a digital line pool. Refer to the
ÒTerminals and sets programmingÓ section of your Installer Guide
for more information.
The CTA 500dm is a B2 channel device and must be assigned a B2
channel DN. The following table shows the default directory
number (DN) that is assigned to the CTA 500dm based on the
physical set port that connects the CTA 500dm to the ICS.

You can change the DN that is assigned to the CTA 500dm in the
same way that you change a DN for a Norstar telephone. Refer to
ICS Installation Guide for more information.
Note: If you use automatic telephone relocation (set relocation) to
change the port used by a CTA 500dm, you must power down
the CTA 500dm before changing the connections. If the
CTA 500dm is not powered down, programming information
will be lost. See ICS Installer Guide for more information
about set relocation.
