EXTender PBXgateway II
MCK’s business voice solutions have
been designed for operational simplicity.
All of the system’s configuration,
management, and administrative and
diagnostic functions may be managed
from the EXTender PBXgateway II
using a direct serial connection, dial
up modem, HTML, Telnet or an inband
network connection from a remote
client. This flexibility allows companies
to maximize their system administration resources and lowers
operating costs.
The EXTender PBXgateway II is
equipped with dual DB-9 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.
• Flexibility
The optional network interface card
allows for direct termination of
T1, PRI and FR lines.
Two DB-9 console ports for easy system
Easy–to-use configuration tools
enable virtual management of remote
users from a central location.
Dual 10/100Base-T ports allow
connection to high-speed Ethernet
networks and separate segments for
voice and management traffic.
• Investment Protection
MCK is committed to providing you
with flexible product solutions for
today’s, and tomorrow’s, needs.
Dual DB-9 console ports enable
multiple management interface connections to operate simultaneously.
Configure the EXTender PBXgateway II
to operate in managed IP network
(Layer 3) or in traditional circuit
switched and frame relay (Layer 2)
• Ease-of-Use
Simple installation process.
• Increased Productivity
Remote employees are able to use
the same full-featured digital sets and
access corporate voice features, like
voicemail, call accounting systems,
unified messaging and ACD systems.
• Network Efficiency
Leverage IP data network infrastructure for both voice and data traffic.
•Support for synchronous and
asynchronous terminal adapters
•Encrypted username and password
allocated by system administrator to
each port
•Network down recovery
•Call suspend mode on ISDN Lines
with Asynch terminal adapters
•Support for IP Precedence and
DiffServ QoS mechanisms
•One EXTender PBXgateway II can
support both serial RVP and RVPoIP
remote clients simultaneously.
•Multiple MCK EXTender 7000 or 6000
for Branch Offices can be attached to
one EXTender PBXgateway II.
•The EXTender PBXgateway II with
the integrated network interface card
terminates T1, PRI and FR networks
directly, eliminating the need for
external CSU/DSU devices.

•When running serial RVP between
an MCK EXTender 6000 and an
EXTender PBXgateway II, the
network access device is connected
via one of the DB-25 WAN ports.
•Remote clients that support serial
RVP are the MCK EXTender 7000

•In RVPoIP applications, the network
access device should be configured
to provide Quality of Service* (QoS)
in order to guarantee voice quality.
•IP or packet-based networks are
terminated through a router.
•Minimal setup programming
required, accomplished via dial up

•Remote clients that support RVPoIP
are the MCK EXTender 7000 and 6000
and the MCK EXTender 4000.
•The EXTender PBXgateway II can
be ordered with or without a 2-port
T1/PRI/FR network interface card.
•The EXTender PBXgateway II can be
configured to run on IP transport or
traditional circuit-switched and frame
relay networks.
•When running RVPoIP, this gateway
can be connected to the LAN via two
10/100Base-T ports simultaneously.
Either port can be configured to carry
voice and/or management, allowing
both traffic types to be transmitted on
separate LAN segments.

*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.
