Uniform Dial Plan
Uniform Dial Plan (UDP) provides a common 3, 4, 5, 6, or 7-digit dial plan - or
even a combination of these - that can be shared among a group of switches. The
UDP applies interswitch dialing and intraswitch dialing. UDP can be used with an
ETN; main, satellite, and tributary switches; and DCS. In a nutshell, UDP
provides extension-to-extension dialing among 2 or more private-switching
systems. Note that for DCS, a uniform 4 or 5-digit dialing plan must be used.
Administering UDP
Following is a list of the forms and fields you need to consider when
administering UDP
Detailed description
UDP routes calls off the local switch by converting the extension number into a
private-network or public-network number. The extension initially dialed by the
user can be 3, 4, 5, 6, or 7 digits. The private-network or public-network number
is formed by deleting digits from and then inserting digits to the front of the
extension. Three types of conversion are supported: AAR, ARS, extension
number portability (ENP) and EXT.
■ For AAR and ARS, the resulting number is analyzed and routed as a
private-network (AAR) or public-network (ARS) number. If you wish to
block further digit conversion by AAR or ARS, you can enter n(o) in the
Conv(ersion) column.
