Portable DNs
Once registration is enabled for your Norstar Companion
system, a series of extension numbers (637 to 696)
automatically becomes available for registration. Check that
an extension number is still available before registering a
portable telephone to it.
•
If the extension number shows a status of Available, that
extension number is ready for registering a Companion
portable telephone.
•
If the extension number shows a status of Registered, a
Companion portable telephone is already registered to that
extension number. In this case, you can either pick a
different extension number, or de-register the current
portable telephone. You must perform deregistration at the
portable and in either an Installer or System Coordinator
programming session.
Press
to view registered and available DNs.
Note: The DN range 637 to 696 can be used by either portable
telephones or ISDN S-loops. You can assign all 60 of
the DNs to S-loops and none to portable telephones.
You can assign up to 30 DNs to portable telephones,
leaving 30 for S-loops. Within these two limits you can
choose a combination of ISDN and portable telephone
DNs. For more information, refer to Modular ICS 5.0
Installer Guide.
Tip -
The extension numbers are based on a system
with three-digit DNs. If your system has more, the first
number will be repeated.
However, your system may also have a different starting
DN (default 221), so these extensions will reflect that
difference.
