MCK EXTender 7000
™
The MCK EXTender 7000 unites
business office telephony across the
entire corporation. Regardless of
location, your employees have access
to the rich set of corporate voice
system features and functionality on
all calls, whether placed over the
WAN connection or the local lines.
Plain old telephone service (POTS)
continues to be available even when
the WAN connection to the central
system fails. System administrators
and telecommunication managers
appreciate the inherent survivability
and remote management capabilities
of the MCK EXTender 7000. Moves,
adds and changes are amazingly easy
and can be done from a central
location. And these are just a few of
the many features and benefits available on the MCK EXTender 7000 for
Branch Offices.
The MCK EXTender 7000 is equipped
with dual console ports (see picture
below). These ports allow a system
administrator to attach a modem to
one and use the other for a local
terminal connection. This versatility
makes remote troubleshooting and
maintenance a breeze.

KEY BENEFITS
•Unified Communications and
Centralized Management
Each employee, whether at the
corporate headquarters or a branch
office, is on the same voice system
and dialing plan and has access
to the same features and applications
resulting in an increase in employee
productivity, an improvement in
customer service and a unified image.
Day-to-day management of the
branch office's users can be done
from a central location, including
moves, adds and changes, as well
as system performance monitoring.
The MCK EXTender 7000 can be
remotely managed through a variety
of remote access options, and users'
port configurations and permissions
are controlled at the central voice
system as if all employees were
physically under one roof.
•Improved Return on Investment
Decentralized organizations with
multiple sites can leverage the full
functionality of a single voice system
and its supported applications. No
need to purchase an expensive and
hard-to-network
voice system or supported business
applications for each remote
branch office.
•Network Efficiency
Ability to directly terminate the
network reduces footprint and
wiring requirements at both the
corporate and remote office locations.
The complete MCK EXTender 7000
and EXTender PBXgateway II solution
is outfitted with a built-in T1, PRI and
frame relay interface eliminating the
need to purchase external network
access devices to connect to the Wide
Area Network (WAN). In addition,
the dual port integrated network card
enables the aggregation of voice and
data traffic for transmission to the
main office as well as the provisioning
of local dialing trunks for the
remote branch office.
•WAN Bandwidth Conservation
The MCK EXTender 7000 processes the
audio portion of calls made to either
extensions at the branch office or to the
local area, resulting in WAN bandwidth
preservation. The MCK EXTender 7000
only sends the voice traffic over the
WAN link when voice features are
invoked.
•Business Quality Voice on Local Calls
The MCK EXTender 7000 relies on its
voice hairpinning feature to guarantee
business quality voice on calls made
and received using the local trunk lines.
•Survivability
Branch office employees connected
to the MCK EXTender 7000 are
able to place and receive local and
emergency calls even when the
WAN link to the corporate voice
network is down.
GENERAL SET-UP GUIDELINES
•The MCK EXTender 7000 connects
across the WAN to the EXTender
PBXgateway II installed on the
digital line side of the corporate voice
system and terminates the digital sets
at the branch office.
•Configuration and programming
can be accomplished via either an
HTML interface, or through a
console interface using a dialup
modem, direct serial connection,
Telnet, or inband RVP.
•Every MCK EXTender 7000 comes
equipped with a dual port network
interface card required for the direct
termination of up to two T1, PRI or
frame relay lines.
•Comprehensive Survivability
Local-hosted mode:
When the WAN link between
the MCK EXTender 7000 and the
EXTender PBXgateway II goes down,
users at the branch office can access
the local trunk lines to place and
receive calls via the PSTN.
•When running MCK's Remote Voice
Protocol™ (RVP) over circuit-switched
networks, the MCK EXTender 7000
interfaces directly with the network
via one of the network interface ports.
KEY FEATURES
•Dual Port Integrated Network Card
The built-in network card available on
the MCK EXTender 7000 terminates up
to two (2) T1, PRI on frame relay lines1
eliminating the need for separate CSUs
or DSUs.
•DSU Functionality
The integrated network card enables
the MCK EXTender 7000 to be the single
network termination device for both
voice and data traffic at the remote
branch office.
•Rich Local Calling Capabilities With
Full Access to corporate voice system
Features
Multiple channels can be allocated from
the T1 or PRI line for use as local trunk
lines. The MCK EXTender 7000
manages voice traffic on calls made or
received on the local trunk lines.
•Long-distance Toll Bypass
Any user connected to the corporate
voice system can be configured to
access a local trunk line on the MCK
EXTender 7000 when placing a call to the
branch office's local area.
•The MCK EXTender 7000 can be
configured to run on IP transport
over circuit-switched, frame relay
and IP networks.
•When running MCK's Remote Voice
Protocol over Internet Protocol™
(RVPoIP) over IP-based networks,
the MCK EXTender 7000 connects to
an IP-capable CSU/DSU or router
via one of the 10/100Base-T ports.
The CSU/DSU or router must be
configured to provide Quality of
Service* (QoS) support in order to
guarantee voice quality in RVPoIP
applications.
Emergency mode:
A single analog port provides Plain
Old Telephone Service (POTS) for
emergency calls in the event of a
wide area network failure.

*MCK's IP-based products utilize Voice over IP (VoIP) technology
to deliver remote voice solutions. The voice quality of these
solutions is dependent on variables such as available bandwidth, network latency and quality of service (QoS) initiatives,
all of which are controlled by the network and Internet service
providers. Because these variables are not in MCK's control,
it cannot guarantee the performance of the user's IP-based
remote voice solution.
