Uniform Dial Plan Facilities

Uniform Dial Plan Facilities
Release 6.0 and later systems, Hybrid/PBX mode only, provide support for
Uniform Dial Plan (UDP) facilities, private network tandem lines/trunks originating
at one or more other MERLIN LEGEND Communications Systems or DEFINITY
Communications Systems. Use the procedures in this section to program the
switch identifiers for private network trunks.
Switch Identifiers
Switch identifiers are 1- or 2-digit prefixes that appear in print reports and are
used by the system for transmission level determination, route checking, and to
identify calls. If your system uses private facilities, you must program switch
identifiers. Switch identifiers indicate the switch connected to the far end of a
private trunk.
The procedures in this topic allow you to add, change, and remove switch
identifiers.
Trunks connected to your system from the CO do not require identifiers. They are,
by default, correctly assigned a null identifier.
When a private networked trunk is deleted, it is assigned a null identifier, as are
trunks newly added to the system.
You can add a switch identifier to a block of trunks, and you can remove a switch
identifier from a block of trunks that use the same switch identifier.
The correct switch identifier for a trunk or block of trunks is determined by the type
of switch to which the trunk is connected and whether or not that switch is a
satellite switch located within 200 miles of the local system. Identifying those
switches greater than 200 miles from the local system as satellite is important in
assuring transmission quality across the private network. The identifiers are
switch numbers that have the following meanings:
Unassigned (null) = trunk connected to CO (central office)
1–20 = trunk connected to a non-satellite MERLIN LEGEND
Communications System greater than 200 miles
21–40 = trunk connected to a satellite MERLIN LEGEND Communications
System
41–50 = trunk connected to a non-satellite, non-LEGEND system (for
example, a DEFINITY Communications System) greater than 200 miles
51–60 = trunk connected to a satellite, non-LEGEND system (for example,
a DEFINITY Communications System)
NOTE: NOTE: NOTE:
The Enter Switch Number screens for the switch identifier procedures
include a Help option that supplies the information above.
