F-2 FX Access
General Description
This feature provides dial access to distant Central Offices using Foreign Exchange (FX) trunks. All incoming calls
to the NEAX2400 IPX from the FX Central Office area are placed to the listed Foreign Exchange Directory number
and are answered by the Attendant in a manner similar to LDN service. Outgoing calls can be made on an Attendant
handled basis using direct or dial access and/or on a direct basis by stations.
Operating Procedure
To place an outgoing FX call from a station
1. Lift the handset and receive dial tone.
2. Dial the FX trunk access code and receive second dial tone.
3. Dial the desired telephone number.
To answer an incoming FX call at the ATTENDANT CONSOLE [A-3]
1. The FX lamp flashes.
2. An audible signal is received.
3. Press the FX or ANSWER key to answer.
4. Process the call in a normal manner.
