Uniform Dial Plan
Uniform Dial Plan (UDP) provides a common 4- or 5-digit dial plan (specified in the
Dial Plan Record) that can be shared among a group of switches. Interswitch dialing
and intraswitch dialing both require 4- or 5-digit dialing. UDP is used with an
electronic tandem network (ETN); main, satellite, and tributary switches; and
Distributed Communications Systems (DCS). In addition, UDP can provide uniform
4- or 5-digit dialing between 2 or more private-switching systems without ETN, main,
satellite, and tributary switches, or DCS.

How to administer UDP
Note:
On the Uniform Dialing Plan form, if you change the
Ext Code
and
Type
fields from a 4-digit or 5-digit extension number to
none
, a warning message informs you that all UDP extension
codes will be lost. The same warning message displays when you
change the
change the
Ext Code
and
Type
extension numbers from 4-digits
to 5-digits or from 5-digits to 4-digits.
Detailed description
UDP routes calls off the local switch by converting the extension number into a
private-network number with 7 digits. This number is formed by prepending a 3-digit
code (of the form XXX) to the (last) 4 digits of the extension number. 3 types of
conversion are supported: UDPCode, AARCode, and ENPNode.

•
For UDPCode and AARCode, XXX is a 3-digit private-network location code,
and the result is analyzed and routed via Automatic Alternate Routing (AAR).
UDPCode conversion prohibits digit conversion via AAR; AARCode conversion
permits it, just as if you dialed the AAR number instead of the extension.

•
For ENPCode, XXX is called an Extension Number Portability (ENP) code. It is
not used for routing; node-number routing is used instead. The ENP code is
chosen based on the first 1 or 2 digits of the dialed string. Because it is not used
for routing, the ENPCode can be independent of location.
