Serial Call - D

S-127
S-127 Serial Call - D
term
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 instructing the
caller to dial the next desired party number is sent out. The caller, by following the instructions, can be connected
to a number of destinations without hanging up.
Operating Procedure
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
telephone/trunk number.
5. The caller dials the desired station/trunk number. When the called party answers, communication begins.
6. When the conversation ends, the caller receives the announcement requesting the caller to dial the next
telephone/trunk number. The caller may successively dial the desired telephone/trunk number.
Note: For the D
term
equipped with a 24-digit LCD, the 16 digits on the left side of the LCD is used for the service
set/cancel indication. The 8-digit space on the right side is blank.
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
term
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
, or 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 for every attempt, and the SERIAL CALL key lights red while SERIAL CALL is set.)
However, the D
term
user must not have any other calls when using this service (i.e. this service cannot be
used together with CALL TRANSFER-ALL CALLS-D
term
[C-11D], CONSULTATION HOLD-ALL
CALLS-D
term
[C-17D], CALL WAITING-TERMINATING [C-12], etc.).
5. The caller can call the station, central office line, tie line, or the Attendant successively by activating
SERIAL CALL.
6. When the call terminates on the central office line/tie line in the multi-line and the called station answers,
the SERIAL CALL key lights red. However, in case the D
term
user answers by CALL PICKUP - GROUP
[C-7]/CALL PICKUP - DIRECT [C-30], it does not light.
7. If SERIAL CALL is not set to the incoming trunk, the caller is not connected to the announcement when
the conversation with the first party ends (after being put on Consultation Hold), but receives reorder tone.
8. This service is available to the incoming route where AUTOMATED ATTENDANT [A-82] or REMOTE
ACCESS TO SYSTEM [R-2] are set.
9. When the registers are all busy when Serial Call is attempted, the caller receives reorder tone.
