REREQUISITES
You should read the information in this chapter before starting the installation
process as you may need to obtain some information or make changes that
could be difficult when on site.
1. Which model of PBX is used at the corporate site
2. Which digital telephones at the remote location will be communicating with
the PBXgateway ports
3. Where the PBXgateway and Remote will be physically located
4. Access to the power to be supplied to the PBXgateway and Remote
5. The PBXgateway (at the corporate site) and the Remote (at the branch
office) must be installed properly and the network link between both devices
must be operational
a) An appropriate network-terminating device must be installed and
functioning at the corporate site and the branch office supporting
10/100BaseT Ethernet interface. The data connection between the
corporate site and the Remote must be operational and configured
correctly.
b) Ensure that the correct TCP/UDP ports are opened to allow the Remote
to connect through the corporate firewall:
- The PBXgateway uses TCP/UDP port 2698
- The Remote uses port 12288 (and 12290 for the Dual Port Remote) for
incoming UDP streams and any port between 1024 and 65535 for
outgoing TCP streams
6. Power
and
Wiring
a) The system is designed to operate at 120-240V AC. Do not apply power
to the Remote until you are instructed to do so in the installation
procedure
b) Install the Remote power supply and cabling away from high RF noise
devices such as computers, fans, fluorescent ballasts and power
supplies
c) Use good wiring practices. Do not run wires over fluorescent lights,
computers, air conditioners, etc., as this can introduce noise.
d) Ensure that the power supply is within 5 feet (1.5 meters) of the Remote
