S-106 Slumber Time - Do Not Disturb
S-106  Slumber Time - Do Not Disturb
General Description
This service allows a slumber time for up to four times per day on a Station group basis. During the slumber time,
all stations in the group concerned are placed into Do Not Disturb mode, and incoming calls (Station/DID/DIT) will
be routed to the Attendant or an announcement machine.
Operating Procedure
No manual operation is required.
Service Conditions
1. The stations for which this feature is set are determined by the telephone number of the group preassigned
by the MAINTENANCE ADMINISTRATION TERMINAL (MAT) and Slumber Time data, not by the
Service Restriction Class.
2. This feature cannot be set for data terminals.
3. This feature cannot be set for Night stations. (NIGHT CONNECTION [N-1] [N-2] take precedence over
SLUMBER TIME - DO NOT DISTURB.)
4. There can be up to seven Slumber Time Groups per system. There is no limitation to the number of stations
that can be assigned to one group.
5. A maximum of four Slumber Time assignments can be made for one Slumber Time Group. When setting
more than one assignment, assure that the Times do not overlap each other. Also, a transfer destination
can be assigned on each Slumber Time Data basis.
6. A station cannot be assigned to more than one Slumber Time Group.
7. A Night Transfer Station cannot be assigned to a Slumber Time Group.
8. During Slumber Time, incoming calls (station/DID/DIT) are routed to an Attendant Console or
announcement machine. When an Attendant Console is designated as the transfer destination, the transfer
call is terminated to the ICPT key on the Attendant Console. When an announcement machine is
designated as the transfer destination but is not assigned in data by AAED command, the caller receives a
busy tone (BT).
9. An announcement machine with one channel can be connected to each station group. When connecting
several station groups to an announcement machine, all groups must be assigned to the same single route
and trunk.
10. Call transfer to a station in Slumber time mode after holding the call by CONSULTATION HOLD [C-17]
is possible only when an Attendant Console is designated as the transfer destination. (The call is
transferred to the Attendant Console.) If the announcement machine is designated as the transfer
destination, the transfer call is routed to reorder tone (ROT) connection.
11. The caller is not always connected to the announcement from its beginning.
12. Call origination is available during Slumber Time.
13. Station group or time is changed, assigned, or cancelled by MAT command.
14. There is no external indication showing Slumber Time set.
15. Any of the following services take precedence over the Slumber Time service:
CALL FORWARDING-ALL CALLS [C-5]
CALL FORWARDING-BUSY LINE [C-2]
STATION HUNTING [S-7, 9]
UNIFORM CALL DISTRIBUTION [U-1]

Serial Call - DtermS-127
S-127  Serial Call - Dterm
General Description
This feature allows the Dtermuser 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 Dtermuser answers the incoming central office line/tie line call.
2. The caller requests SERIAL CALL, and the D
termuser presses the SERIAL CALL key.
3. The caller tells the desired station/trunk number to the D
termuser; the Dtermuser 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 Dtermequipped 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
termwith 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 Dterm,orthe
Dtermshould be previously designated as the Direct-In Termination station.
4. The D
termmay 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
termuser must not have any other calls when using this service (i.e. this service cannot be
used together with CALL TRANSFER-ALL CALLS-Dterm[C-11D], CONSULTATION HOLD-ALL
CALLS-Dterm[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
termuser 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. 
						

							NEAX2400 IPX Feature Programming ManualPage 726NDA-24297, Issue 1
S-127 Serial Call - Dterm
Service Conditions (cont’d)
10. Whether to send the announcement can be determined on a system basis. If the announcement is not sent,
the caller receives dial tone. Both the first and the second announcement is connected in single connection,
and the caller receives no tone until the announcement is sent.
11. When Serial Call is attempted, and the caller encounters all announcement trunks busy or when there is
no announcement trunk, the caller receives dial tone.
12. The caller can dial the desired telephone/trunk number during the announcement.
13. This service is provided only when the caller uses the DTMF telephone.
14. The caller is connected to the announcement when the caller is engaged in a two party connection with the
station, central office line, tie line, or the Attendant and then the station, central office line, tie line or the
Attendant releases.
15. If the caller does not dial any number after the announcement, the caller receives no tone until the register
prepause timer expires.
16. In case the register prepause timer expires after the announcement, whether to recall to the operator D
term
user or to release the call automatically can be selected on a system basis.
17. When recalling to the D
term, whether to end or continue this setting can be selected by system data.
However, in case the central office trunk works with Loop Start system (route data LSG=0), release cannot
be detected; therefore, when recall to the D
term, this setting is ended. If this setting is ended, the Dtermuser
can press the SERIAL CALL key again and reset.
18. Recall to the D
termselected at item 17 is activated with the following steps and ringing is according to the
ringer pattern 5 ASYD System Data 3 Index 7.
a.) In case the D
termsetting SERIAL CALL is free, the destination is the set line and only the Dterm
is called. If the set line is accommodated in the other Dtermmulti-line, the other Dtermbecomes
busy status (lights in red) and CALL FORWARDING–ALL CALLS [C-5] and FORWARDING
- DON’T ANSWER [C-3] is not available. When the set line is the my line of the D
term,theLCD
displays RECALL. (Ordinary transaction for recall to the Dtermuser)
b.) In case the Dtermsetting SERIAL CALL is busy, another free line among the Dterms is selected by
the same transaction as ordinary serial calling. Therefore, CALL FORWARDING - ALL CALLS
[C-5], CALL FORWARDING - BUSY LINE [C-2] and STATION HUNTING - CIRCULAR [S-
7] are available, and the LCD on the D
termwhich is selected as a Prime Line indicates RECALL.
CALL FORWARDING - DON’T ANSWER [C-3] is not available. In case to end the setting is
selected at item 18, the central office line/tie line is released. (reorder tone is sent out); in case to
continue is selected, dialing of the next number is allowed. (Dial tone is sent out.)
19. Conditions for restriction are as follows:
a.) When the dead number or the dead level is dialed (even if the dead number announcement data is
assigned, the call is not connected to this announcement, but it is recognized as a redial call. If the
second announcement data is assigned [AAED EQP = 35], this announcement has priority).
b.) In case of inter digit timer timeout while the telephone number is dialed.
c.) When the called station does not answer for 30 seconds (if CALL FORWARDING - DON’T
ANSWER [C-3] is set, the call is forwarded).
d.) When the called station is busy (if CALL FORWARDING - BUSY LINE [C-2] is set, the call is
forwarded).
e.) The connection is restricted:
when the number where the connection with the central office line/tie line is restricted is dialed.
when the access code dialing for trunk call origination is restricted.
when the access code is dialed for trunk call origination, and inter digit timer expires before the
call originating route is determined, resulting in restriction.

Serial Call - DtermS-127
Service Conditions (cont’d)
when the outgoing trunks are all busy (if Tandem Trunk Queuing service is set, the service is
activated).
20. After the second announcement is sent out, whether to allow dialing of the next number or to release the
call automatically can be selected on a system basis.
21. The announcement can be either 16, 32, or 60 seconds, depending on the key setting of the announcement
trunk (PA-4DATA). The announcement trunk should always be connected in single connection.
22. When the caller attempts trunk call origination by this service and encounters restriction, the class change
service via authorization code dialing is not available.
23. The following services are denied toward a line or trunk involved in Serial Call:
CALL FORWARDING - ALL CALLS [C-5]
CALL FORWARDING - BUSY LINE [C-2]
CALL FORWARDING - DON’T ANSWER [C-3]
CALL PICKUP - DIRECT [C-30]
CALL PICKUP - GROUP [C-7]

CALL WAITING - TERMINATING [C-12]
STATION HUNTING - CIRCULAR [S-7]
STATION HUNTING - SECRETARIAL [S-8]
STATION HUNTING - TERMINAL [S-9]
24. When the called station via Serial Call is busy, STEP CALL [S-13] is not available.
25. When the call is extended to a trunk, the call is charged to the incoming trunk (the caller).
Programming
STEP 1:ASYD- System data 1, index 007, bit 5 = 0/1: when dialing a vacant level, unused number, timeout,
recall, or restricted connection, the caller will be (0) able to redial / (1) disconnected.
System data 1, index 435, bit 0 = 0/1: Serial Call in service No/Yes.
System data 1, index 435, bit 1 = 0/1: after pre-pause timer, recall/disconnect.
System data 1, index 435, bit 2 = 0/1: when recalling, the service will end/continue.
STEP 2:AKYD- FKY 84 = Serial Call.
STEP 3:ADSL- Assign SCALL key; Assign SN=4 (Communication in Progress) and FKY=84 (Serial Call).
This command is used for assigning a function to each soft key.
STEP 4:AAED- EQP 34 (Auto Attendant first announcement) C = 0, R = 1, A = 1, M = 0.
EQP 35 (Auto Attendant second announcement) C = 0, R = 1, A = 1, M = 0.
FCCS Programming 
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node.
 Note
STEP 1:AAEDN- EQP 34 (Auto Attendant first announcement) C = 0, R = 1, A = 1, M = 0.
EQP 35 (Auto Attendant second announcement) C = 0, R = 1, A = 1, M = 0.
Note:When using ASYDL or ASYDN to program an FCCS feature, the basic programming of ASYD is required
in addition to ASYDL or ASYDN.
