Safety Considerations
IMPORTANT SAFETY INSTRUCTIONS
•Do not install this product near water.
Example: In a wet basement location.
• Do not overload wall outlets, as this can result in the risk of fire or electrical shock.
• Do not attach the power supply cord to building surfaces. Do not allow anything to rest on the
power cord. Do not place this product where anyone can step on the cord.
•Do not operate the system if chemical gas leakage is suspected in the area. Use a telephone
located in another, safe area to report the trouble.

The EXTender 4000 provides remote voice access to a corporate system for a single remote user.
Remote users can connect to a PBXgateway™ via a 10Base-T Ethernet connection using IP packet
transmission.
The remote users’ telephones connect to the EXTender 4000 via an RJ-11 telephone jack. The user’s
telephone traffic is placed in IP packets and sent out to the corporate LAN and then to the PBXgateway
via a 10Base-T Ethernet connection in the PBSX gateway.
The EXTender 4000 provides a choice of three voice compression algorithms: G711, G729A, and G726
(24 and 32 Kbps ADPCM options) to reduce bandwidth requirements. The EXTender 4000 extends the
full functionality of the system to a remote location, via IP over a LAN.
All voice traffic and signaling information from the digital telephone system is packetized by Remote Voice
Protocol (RVP
voice packets can share the Ethernet network with other common data devices. The remote user can also
connect a PC to the LAN through an RJ-45 Ethernet jack on the EXTender 4000, which acts as a hub.
The voice and signaling traffic is transmitted over the LAN between the EXTender 4000 at the remote
location and the PBXgateway at the central location. At the Gateway, the packets are converted back into
the system protocol and sent to the system via an RJ-21 cable.
IP-based products utilize Voice over IP (VoIP) technology to deliver remote voice solutions. The voice
quality of these solutions depends on variables such as available bandwidth, network latency, and Qu ality
of Service (QoS) initiatives, all of which are controlled by the network and internet service providers.
Because these variables are not within our control, we cannot guarantee the perform ance of the user’s
IP-based remote voice solution.

). These packets are encapsulated into IP packets and sent out over the Ethernet. The
You must meet the following requirements before installing the EXTender 4000:
Networking
•An appropriate network-terminating device must be installed and functioning at both the corporate
facility and the branch office.
•The data connection between the corporate facility and the EXTender 4000 must be operational
and configured properly.
•The network termination equipment must support a 10Base-T Ethernet interface.
TCP/UDP
Ensure that the correct TCP/UDP ports are opened to allow the EXTender 4000 to connect through your
company firewall. The following TCP/UDP port requirements must be met:
Remote Location
The EXTender 4000 uses port 12,288 for incoming UDP streams and any port between 1024 and 65535
for outgoing TCP streams.
Gateway Location
The Gateway unit uses TCP/UDP port 2698.
Power and Wiring
The system is designed to operate at 120 VAC. Do not apply power to the EXTender 4000 until you are
instructed to do so in the installation procedure.
•Install the EXTender 4000 power supply and cabling away from high power/high RF noise devices
such as computers, fans, fluorescent ballast, and power supplies.
•Use good wiring practices. Do not run wires over fluorescent lights, computers, air conditioners,
etc. as this can introduce noise.
•The distance between the telephones and the EXTender 4000 should NOT exceed 500 feet.
