Citel 4100 Guía De Instalación

 

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
