10 Distributed Communication System

With Uniform Dial Plan, a unique 4- or 5-digit number is assigned to each station on the network. This unique number (location code plus extension) can be used at any location in the Electronic Tandem Network to access that station. DEFINITY ProLogix Solutions 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.

Uniform Dial Plan is a standard feature of DEFINITY ProLogix Solutions.

Distributed Communication System

For a multilocation company that requires several systems, Distributed Communications System (DCS) may be the answer. DCS is a network arrangement of private switches, referred to as nodes. The maximum number of nodes that can be in a DCS varies from 2 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 Distributed Communication System may also be provided across a Software Defined Network.

The functions and features of Distributed Communication System are made possible by the use of an advanced interprocessor data link connecting each switch, allowing call-processing to be passed from one switch to another. The data link supplies transparency of selected features and efficient utilization of facilities that can be shared.

Feature transparency means that features work the same from the user’s perspective, whether the telephones involved are assigned to the same switch or different switches. Users in a DCS can dial each other with four or five digits as if they were all on the same switch.
