Introduction
MCK's EXTender 3000 provides remote workers and small branch offices seamless connectivity to the cor-
porate LAN.
Remote employees can: place and receive calls through the PBX/Key System; use four/three-digit internal
dialing; transfer calls; set up conference calls; have a corporate-based receptionist screen calls; access the
voice mail, auto-attendant or any other software residing on the PBX/Key System. The EXTenders work
with existing corporate, digital telephone sets. Transmission is over the public telephone network using
ISDN, or BRI lines.
Remote employees can, at the same time, establish data sessions (e.g. connecting to Internet Service Pro-
vider or access their corporate LAN). There are three data communications methods: Serial, Dial-up or
Ethernet.
The Remote employee also has an additional analog port available for an analog device, such as a fax
machine.
How the Connection Works
The connection to the ISDN network is done via the built-in U or S/T interface. The Office Module connects
to a digital port on the PBX/Key System located at the corporate office, and the Remote Module connects to
a digital phone set at a remote location.
TM
The Office and Remote Module, includes MCK's Remote Voice Protocol
software. The software, com-
presses, packetizes and encrypts voice and PBX/Key System signals to condition them for transmission over
a public, circuit-switched network.
Once the installation has been completed, your Remote Module will enable your extended phones to func-
tion exactly like your deskset at the office.
