Fax CNG Detection (#505, Group 8)

Use this feature to allow voice calls and fax calls to be received on the same line, which eliminates the need for a dedicated fax line.

When the start button on a fax machine is pressed, the fax machine sets up to send a fax. The
sending fax machine sends a special tone called a calling tone or CNG tone. This tone is sent until the call is answered. If another fax machine answers, the appropriate signals are sent back to the calling fax machine to send the fax transmission.

If you are using this feature on a T1 line with Direct Inward Dialing (DID), set your fax machine to answer in less than four rings.

When an incoming call is answered by PVM, PMVS, PARTNER MAIL, or ASA/DXD, the system determines if the incoming call is a fax. If the system is set up to automatically route incoming fax calls to fax machine(s), it automatically transfers the call to Hunt Group 8.

If your voice messaging system is PARTNER Messaging and you use the Fax CNG Detection feature, do not program PARTNER Messaging to assign a fax extension to an Automated Attendant. For more information, see the PARTNER Messaging System Manager’s Quick Reference.

  • To use Fax CNG Detection, you must have a voice messaging system or ASA/DXD. You must also have your system configured in one of these ways:
    — PARTNER ACS Release 7.0 as a stand-alone module.
    — T1 module in slot 1; PARTNER ACS Release 7.0 in center slot; any modules in remaining slots.
    — 1600 DSL module in slot 1; PARTNER ACS Release 7.0 in center slot; any modules in remaining slots.
    — 012E/362EC module in slot 1; PARTNER ACS Release 7.0 in center slot; any modules in remaining slots.
    — 308EC Release 3.0 or later/200/206/400 module in slot 1; PARTNER ACS Release 7.0 in center slot; any modules in remaining slots.
    — 308EC module prior to Release 3.0 in slot 1; PARTNER ACS Release 7.0 in center slot; at least one 308EC Release 3.0 or later in remaining slots.
    — 308EC module prior to Release 3.0 in slot 1; PARTNER ACS Release 7.0 in center slot; at least one 308EC/012E/362EC in remaining slots.
  • When lines appear on a fax extension, make sure that the fax machine does not automatically answer outside calls on these lines. There are three ways you can do this:
    — Set the fax machine for delayed pickup.
    — Use Line Ringing to change the ring options on the fax extension to either delayed ring or no ring.
    — Use Line Assignment (#301) to remove all outside lines from the fax extension (this is the recommended way).
  • Incoming fax detection is activated automatically by assigning extensions to Hunt Group 8.
  • If a PARTNER MAIL system is connected to the system and fax detection is being done via PARTNER MAIL, no extensions should be assigned to Hunt Group 8.
