Call Waiting Indication; Camp-On - Nortel TFC002 Manual

— The Call Transfer feature operates according to the capabilities of the
system on which the call transfer is being attempted.
— Disconnect supervision must either be provided by the incoming CO
trunk or be repeated by the TIE trunk from the Remote site. If not, the
Meridian 1 disallows these types of connections.

Call Waiting Indication

Calls waiting in queue for RLT at each Remote location are not included in
the Call Waiting Indication given to the CAS attendants. Calls that have
seized an RLT and are queued for service at the Main location are included in
the Call Waiting Indication.

Camp-On

When the CAS attendant attempts to complete a call to a telephone that is
busy, the call is automatically camped-on to the busy telephone, provided that
a call is not already camped-on to that telephone. The Remote site transmits
a camped-on confirmation tone (a 100-ms burst of 440-Hz tone) to the CAS
attendant over the RLT and then connects to the calling party. If the calling
party wants to wait, the CAS attendant releases and a disconnect signal is
transmitted to the RLT, which releases. When the camped-on telephone goes
on hook, the camped-on call is automatically presented.
If the called telephone does not answer within the specified time, the Remote
site seizes an idle RLT and presents the calling party to the CAS attendant.
When the CAS attendant answers, answer supervision is detected by the RLT,
and the Remote site sends a 100-ms burst of 440-Hz tone to the CAS
attendant so that the attendant can answer appropriately. The CAS attendant
can then release from the calling party with the Release key, or from the
called telephone, by operating the Release Destination key.
Direct inward dialing (DID) calls to a busy telephone can be routed to an RLT
and can provide the attendant with the same tone as for a dial "0" call. This
occurs only for telephones that have a Call Forward Busy Allowed (CFA)
Class of Service and no other forwarding or hunting arrangements defined.
