Uniform Dial Plan provides a common 4- or 5-digit dial plan that can be shared
among a group of private-network switches. Interswitch and intraswitch dialing both
require 4- or 5-digit dialing. This feature is used with either:
An electronic tandem network (ETN)
•
A main/satellite/tributaryconfiguration and Distributed Communications Systems
•
(DCS).
In addition, it can provide uniform 4- or 5-digit dialing between 2 or more private-
switching systems without ETN, main, satellite, and tributary switches, or DCS.
With Uniform Dial Plan (UDP), a unique 4- or 5-digit number is assigned to each
station in the network. A unique number (private-network location code plus
extension) can be used at any location in the ETN to access that station. Avaya IP600
enhances the standard uniform dial plan with the unrestricted 5-digit uniform dial
plan, which allows up to five digits to be parsed for call routing.
For a multilocation company that requires several systems, DCS may be the answer.
DCS is an arrangement of private-network switches, referred to as nodes. The
maximum number of nodes that can be in a DCS complex varies from 20 to 63,
depending on the particular configuration of switches. DCS nodes can be physically
located in the same building, spread across a campus, or scattered across the country
or around the world. Digital trunks interconnect the switches that serve the DCS
complex. The links connecting a DCS may also be provided via a Virtual Private
Network (VPN).
The functions and features of DCS are made possible by the use of an advanced
interprocessor data link connecting each switch, allowing call-processing information
to be passed from one switch to another. The data link supplies selected feature
transparency and efficient utilization of shared facilities.
