1. PRODUCT OVERVIEW
Introduction This Chapter provides a product overview of the
PBXgateway, Branch Office EXTender 6000, and
EXTender 4000 units. The information includes: basic
functionality, connectivity, voice compression,
configuration and diagnostics.
Product The PBXgateway is a multi-user telephony device enabling
Summary remote teleworkers seamless connectivity and full
functionality of the corporate Private Branch Exchange
(PBX). The PBXgateway is referred as a "gateway "
because it is the central receiving point for routing voice
conversations from one or more locations to the PBX.
Teleworkers, usually working from an off-site location,
can place a call through the corporate PBX by simply
dialing the number as if they were in the main office. The
remote phones can be connected to either a single-user
device (such as the EXTender 4000), or multiple-user units
(such as the Branch EXTender 6000). The single-user
device is commonly referred to as a "Remote unit", and the
multi-user device is referred to as the "Branch Office unit".
The Gateway, Remote units and Branch Office units are
linked through a wide variety of network devices (TA,
FRAD, CSU/DSU) and network types (ISDN, IP, Frame
Relay, TI, Fractional T1, ATM).
