S-127 Serial Call - D
term
(Series 6100 software feature)
General Description
This feature allows the D
term
user to set SERIAL CALL to the central office line/tie line call and extend the
call to the desired station/trunk. When the communication with the desired party ends, the announcement
guiding the caller to dial the next desired party number is sent out. The caller, by following the guidance,
can be connected to a number of destinations without hanging up.
Operating Procedure
To operate:
1. The D
term
user answers the incoming central office line/tie line call.
2. The caller requests SERIAL CALL, and the D
term
user presses the “SERIAL CALL” key.
3. The caller tells the desired station/trunk number to the D
term
user; the D
term
user extends the call
to the desired station/trunk using Consultation Hold.
4. When the conversation ends, the caller receives the announcement requesting the caller to dial
the next station/trunk number.
5. The caller dials the desired station/trunk number. When the called party answers,
communication can begin.
6. When the conversation ends, the caller receives the announcement requesting the caller to dial
the next station/trunk number. The caller may successively dial the desired station/trunk number.
Service Conditions
1. Whether to activate this service can be determined on a system basis, but not on a tenant or
incoming route basis. Therefore, it is not available to activate this service for each incoming
route.
2. Serial Call can be set only for the incoming central office line, tie line, and ISDN line. It cannot
be set for the station or the outgoing trunk.
3. The station that can set/cancel Serial Call is the D

with the “SERIAL CALL” key. In case of
the incoming call from a ringdown trunk, the call has to be transferred from the Attendant to the
D

term
should be previously designated as the Direct-In Termination station.
4. The D
term
may set/cancel Serial Call by pressing the “SERIAL CALL” key any time while
engaged in a call with the incoming trunk party. (The LCD indicates set (SERIAL SET)/cancel
(SERIAL CANCEL) for 5 seconds every attempt and the “SERIAL CALL” key lights red while
Serial Call is set
