After the table is scanned and the best match is found, the programmed
digit manipulation (addition and/or deletion) associated with the entry is
performed. If the digit manipulation results in an invalid dial-plan extension,
the call is routed to the destination for unassigned DID calls.
Characteristics and valid entries for the Dial-Plan Routing Table are as follows:
■
The factory-set table value for service is Empty (not specified). Entries that
remain empty are skipped when the system searches for a match.
■
There can be up to 16 entries (0 through 15).
■
The service can be specified as any one of the supported services, Other,
No Service, or All Services.
■
If the service is programmed as All Services, it matches any input and thus
acts as a wild card. If the B-channel receiving the incoming call is also
programmed for call-by-call service selection, the system retrieves the
service type as supplied by the FX because an incoming call could be
arriving on any of the services.
■
An entry programmed for No Service matches calls in which no service is
supplied by the foreign exchange or B-channel group.
■
Each pattern can have 0 through 8 digits. The default is blank.
■
The number of digits can be 0 through 14. A value of 0 in the table
represents “any number” and thus acts as a wild card. The default number
of digits is 0.
■
The maximum number of digits to delete is 14.
■
The digits to add include the digits 0 through 9. The length of this item is 0
through 4 digits. The default is blank.
■
The digit count and pattern are optional. When not programmed, they are
considered wild cards that match any input.
Display Operation.
The telephone display provides call-related information about
incoming PRI calls delivered over the B-channel, if available. Otherwise, it
displays the line label and the digits dialed.
Beginning with Release 3.0, hyphens are inserted between the digits on incoming
calls (for example,
555-1234
for a 7-digit display and
123-555-1234
for a 10-digit
display). Any other number of digits appears without hyphens.

NOTE:
PRI display support for Release 2.0 and later applies to MLX display
telephones only. There is no PRI display support for analog multiline
telephones.
