Lucent Technologies 555-230-220 manual Analog Station Operation

ASAI and Domain Control

A multifunction station user can also have other call appearances with alerting, bridged, or held calls while requesting the Third Party Answer capability on a call.

If the station is active on a call (talking), listening to reorder/intercept tone, or does not have an idle call appearance (for ACB, ICOM, PCOL, or TEG calls) at the time the Third Party Answer capability is requested, the request is denied.

Analog Station Operation

For an analog station user, this capability is successful only under the following circumstances:

■The user is being alerted on-hook (and is manually taken off-hook within five seconds).

■The user is off-hook idle (or listening to dial tone) with a call waiting; the ECS drops the dial tone (if any) and answers the call waiting call.

■The user is off-hook idle (or listening to dial tone) with a held call (soft or hard); the ECS drops the dial tone (if any) and answers the specified held call (there could be two held calls at the set, one soft-held and one hard-held).

An analog set may only have one or two held calls when invoking the Third Party Answer capability on a call. If there are two held calls, one is soft-held, the other hard-held. Third Party Answer of any held call (in the absence of another held call and with an off-hook station) resets the switch-hook flash counter to zero, as if the user had manually gone on-hook and answered the alerting/held call. Third Party Answer of a hard-held call (in the presence of another, soft held call, and with an off-hook station), leaves the switch-hook flash counter unchanged. Thus, the user may use subsequent switch-hook flashes to effect a conference operation between the previously soft-held call and the active call (reconnected from hard-hold). Third Party Answer of a hard-held call in the presence of another soft-held call and with the station on-hook is denied. This is consistent with manual operation because when the user goes on-hook with two held calls, one soft- and one hard-held, the user is re-alerted and goes off-hook, and the soft-held call is retrieved.

If the station is active on a call (talking) or listening to reorder/intercept tone at the time the Third Party Answer capability is requested, the request is denied (CS0/17
