USING PBX

For a PBX connection, first, you should:
• Check that the PBX fulfills the requirements for FCT
connectivity (see "Installing an FCT connected to a PBX"
on page 8)
• Follow all FCT installation steps specified in "Preparing
your FCT" and "Installing the FCT on the wall" on pages
10 and 13
Warning!: the PBX may require specific programming; both
this and the FCT installation should be done by specialized
service personnel.
If you are using an analog PBX - Disconnect the telephone you
have used for testing purposes and connect the cable from the
chosen analog trunk of the PBX to the FCT telephone line.
If you are using a 2B+D ISDN digital PBX - Disconnect the
telephone you have used for testing purposes and follow the
instructions in the FI12 installation guide. (See "FCT
accessories" on page 41)
If you are using a Least Cost Routing (LCR) programmed
PBX, check your PBX programming guide to see how to
program your PBX to make certain calls through the FCT
trunk. Once LCR is programmed, make a call to a mobile
telephone number. See if the call is established through the
FCT and also check the speech quality. Ask the person who
answers to call you back to confirm that the installed FCT can
receive calls properly.
If the PBX does not offer the LCR option, choose the FCT
trunk manually with a specific prefix. Check the installation in
the same way as before.
If you encounter problems, please contact your Distributor or
network operator.
