Managing Telephone Features
3. If you want the system to display calling party information of the primary telephone, the
Send EMU Visitor CPN field must be set to y. There are areas where public network trunks
disallow a call if the calling party information is invalid. In this case, there can be instances
where the extension of the primary telephone is considered invalid and the extension of the
visited telephone must be used. To use the extension of the visited telephone, set the Send
EMU Visitor CPN field to n.
Note:
If you set the Send EMU Visitor CPN field to y, you must set the Format field on
Note:
the same page to either public or unk-pvt.

Activating EMU
Use the following steps to activate a visited telephone:
1. At the visited telephone, enter the EMU activation facility-access-code (FAC). You must
enter the EMU activation FAC of the server in the location where you are dialing from.
2. Enter the extension of your primary telephone set.
3. Enter the security access code of your primary telephone set. This is the security code
administered on the primary telephone's station form on the home server.
If the registration is successful, you hear confirmation tone.
If the registration is not successful, you hear audible intercept. Audible intercept is provided
when:
- The registration was rejected by the home server.
- The telephone where the registration attempt is made is not administered for EMU
use.
- The T1 timer expires at the visited server.
If the home server receives a request from a visited server for a telephone that already has an
EMU visitor registration active, the old registration is terminated and the new registration is
approved.
If the primary telephone is in-use when a registration attempt is made, the registration attempt
fails.
