MERLIN LEGEND Communications System Release 6.1

Issue 1

Network Reference 555-661-150

August 1998

5 Network Management

 

Uniform Dial Plan Routing

Page 5-27

 

 

NOTE:

Extension outward and toll calling restrictions are ignored when a user dials a non-local dial plan extension. However, FRL extension restrictions remain in effect.

For Release 6.1 and later, when using a centralized VMS/AA, at the (VMS hub) system where the centralized VMS/AA resides, assign the extension for the ports used to connect the centralized VMS/AA as members of an integrated VMI calling group and set the FRL for these extensions to 3.

At each remote MERLIN LEGEND system sharing the centralized VMS/AA, assign a pattern for the integrated VMI conversion number that is not used for normal private network calls. Set up the routes associated with the pattern as follows:

Assign a private network facility pool that contains a pool of PRI or tie trunks, but not mixed trunk types.

Assign an FRL of 0.

Valid Entries

0 to 6

Digit Absorption

5

Use this procedure to specify how many of the digits dialed (0 through 11) by the caller should be absorbed (not sent over the trunk) by the system when a UDP call to a non-local extension is made on an identified route. Digit absorption can be used to modify the digits that are actually sent to a non-local system.

For Release 6.1 and later, when coverage or overflow calls are routed to a centralized VMS/AA, the same extension number is assigned to the integrated VMI calling group created on each system sharing the centralized VMS/AA (including the VMI hub system). This configuration allows users to dial the same extension number to retrieve voice mail messages regardless of location. For each remote system, the number of digits absorbed should equal the length of the VMI conversion number (the non-local member in the integrated VMI calling group used to route calls to the centralized VMS/AA). The VMI conversion number has no corresponding physical extension. Digit absorption removes the VMI conversion number so that the extension for the centralized VMS/AA at the VMI hub can be added by prepending.

Entries of 1 through 11 indicate that the system should not send the specified number of digits, starting with the first digit dialed by the user.
