The PBX should meet the following generic requirements for
FCT connectivity:
• The PBX must offer the possibility of analog trunks.
Otherwise, the ISDN FI12 adapter accessory will be
necessary. (see “FCT accessories” on page 41).
• 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 Router
(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 F251m 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 “FCT
accessories” on page 41).
