Warning!: please, before you start any connections
refer to section “Safe and Efficient Use” on page 40
in this guide and contact your network operator if
you have any questions.
Warning!: to get a good FCT protection against
electrical discharges and the best audio quality,
a good grounding of the power supply is strongly
recommended.
Installing an FCT connected to a PBX
The FCT is designed to provide a telephone line
(RJ11 connector) that behaves in the same way as an
analog trunk.
Generic requirements
The PBX should meet the following generic
requirements for FCT connectivity:
• The PBX must provide analog trunks. Otherwise,
the ISDN FI12 adapter accessory will be necessary.
See Accessories on page 38).
• One position of the trunk must be assigned to each
FCT terminal.
• The trunk card must support either Busy Tone
Detection (BTD) or Polarity Reversal Detection on
answer and release.
• The PBX can be programmed to utilize Least Cost
Routing (LCR), if available, to automatically choose
the FCT trunk when suitable.
• If the PBX does not offer LCR, choose the FCT
trunk manually with a special dialed prefix.
The FCT terminal is compatible with most analog
PBXs on the market and with most of the available
2B+D ISDN digital output trunks, via its accessory
ISDN FI12 adapter. See Accessories on page 38.
