Introduction to DBS T1 Networking
Overview
Description of T1 Networking
Two to four DBS systems may be interconnected using T1 connections to
create a DBS telephone network. The DBS systems may be located in the
same building, separate buildings, across the city or across the country.
DBS T1 Networking provides the following features:
• Network Extension to Extension Calling
• Call forwarding to Network Extensions
• Paging to Network DBS
• Network Route Selection
• Remote DBS CO Access
• SMDR Network Support
• Common Network Attendant Calling (calls that revert to the attendant will
The T1 Network consists of two to four DBS systems that use 4-digit
numbering. The first digit (1 to 4) specifies the network DBS location (or
node) to receive the call. The remaining digits follow the conventional three-
digit DBS numbering plan. For instance, dialing 2105 selects extension 105
on Network DBS node 2.
