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.

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.

•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.

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 Installer Guide.
