Introduction
1
An overview of the functioning and specifications of the
DEFINITY
® Extender
The DEFINITY
® Extender enables DEFINITY telephone users to
be a fully functional part of the PBX telephone system with a digital
telephone located any distance off-premise. The Extender is
transparent to the user and retains access to the features and
functions of the DEFINITY Enterprise Communications Server
(ECS). In addition, an RS-232 data port extension is incorporated,
allowing the user to connect off-premise RS-232 equipment to
equipment at the PBX location. 
						

							Introduction
1-2   Issue 3   July 1997
System Operation and
Configuration
The DEFINITY Extender system is designed for use with a
DEFINITY ECS of Version 3, Release 3 or later. The Extender
system consists of two modules. One module, identified as the
Switch Module, connects to your PBX. The other module, identified
as the Remote Module, connects to your DEFINITY telephone at
your off-premise location. Figure 1-1 shows the Extender system
configuration.
Figure 1-1.  System Configuration
The modules communicate via a single two-wire voice-grade circuit
that can extend your DEFINITY telephone to virtually unlimited
distances. See “Specifications” later in this chapter for detailed
circuit specifications.
