S-11 Station-to-Station Calling
General Description
This feature permits any user to directly dial another station within the NEAX2400 IMX system without operator
assistance.
Operating Procedure
1. Lift the handset; receive dial tone.
2. Dial the desired telephone number.
Service Conditions 
1. If the called station is off-hook, the originating station receives a busy tone. Otherwise, the called station
will ring and the caller will hear a ringback tone. 
2. If the called station remains unanswered for longer than a preset interval, the call will not be transferred
to the ATTENDANT CONSOLE [A-3], unless CALL FORWARDING-DON’T ANSWER [C-3] is
provided.
3. If the called station is busy, the call will not be transferred to the Attendant Console, unless CALL
FORWARDING-BUSY LINE [C-2] is provided.
4. Station-to-station calling between TENANTs [T-12], will not be restricted, unless programming for such
restriction is entered in System Data.
5. The maximum number of digits per telephone number is 16.
6. The same telephone numbers cannot be duplicated in different TENANT [T-12] groups. 
7. Calling Party Release/Called Party Release/Both Party Release/First Party Release can be selected on a
system basis.
8. The following features, if activated, may result in the calling user to be connected to a station other than
the dialed station:
CALL FORWARDING - ALL CALLS/BUSY/DON’T ANSWER [C-5, 2, 3]
CALL PICKUP  [C-7, 30]
STATION HUNTING  [S-7, S-8, S-9]
UCD [U-1]
9. When HOT LINE [H-1] service is provided, the calling user automatically connects to a preset number by
going off-hook. The preset number may be another station, an Attendant, or an outside party.
10. When the calling user dials an unassigned telephone number, the call will be routed to reorder tone or
Announcement (option).
11. An option per station line is available to eliminate the STATION 5dB PAD [S-62].
Interactions
1. The ATNR command is required for all station-to-station calling.
2. The normal 5 dB PAD loss inserted for station-to-station calling may be eliminated on a per-station basis.
For these stations, assign a Service Feature Class that allows SFI 50, Removal of 5dB pad for Off-Premises
Extensions (OPX).

Step Call S-13
S-13 Step Call
General Description
This feature allows the Attendant or user, upon calling a busy station, to call an idle station by dialing an additional
digit. This feature will operate only if the number of the idle station is identical to that of the busy station in all
respects, except the last digit.
Operating Procedure
1. The dialed station (220) is busy.
2. Dial “5” (or any digit between 0 and 9).
3. If Station 225 is idle, the call will be connected there.
Service Conditions 
1. This feature can be provided for all stations and the Attendant Console(s).
2. STEP CALLING can be in any order, 0-9 or 9-0.
3. If the second selected station is also busy, STEP CALLING can continue until a station rings.
4. If a station is set for any type of CALL FORWARDING (ALL CALLS, BUSY LINE NO ANSWER [C-
2, 3, 5]), the call forwarding will take effect.
5. CALL FORWARDING - ALL CALLS/BUSY LINE [C-2, 5]: The activation of a call forwarding feature
by the called station can cause a STEP CALL to be completed to a station other than the dialed station.
6. CONSULTATION HOLD - ALL CALLS [C-17]: STEP CALL can be activated when a busy tone is
returned on a Consultation Hold attempt.
7. The STEP CALL feature is not operational for trunk incoming calls to PBX stations.
Note:
STM:2 and STS:6 should be assigned as 1 by ASTD command, to restrict Step Call on DID.
8. A STEP CALL to a station in LINE LOCKOUT [L-3] or maintenance busy state will result in a reorder
tone.
Interactions 
1. A STEP CALL can search through an entire group to find an idle station. 
2. CALL FORWARDING [C-2, 3, 5]: STEP CALL will respond according to the numbering scheme of the
dialed station. Station A (7526) call forwards his phone to Station B (7128). Station B is busy. The calling
station dials 7526 and receives busy tone. The calling station then dials 2. The call terminates at 7522.
3. CONSULTATION HOLD-ALL CALLS [C-17]: STEP CALL can be used when encountering a busy
station via CONSULTATION HOLD.
4. LINE LOCKOUT [L-3]: A STEP CALL to a station in LINE LOCKOUT [L-3] results in reorder tone.
Another digit can be dialed to reach an idle station.
5. When STEP CALL [S-13] is used after LAST NUMBER CALL [L-6, 6D] service with the access code,
the destination of STEP CALL is changed depending on the access code of the LAST NUMBER
CALLED [L-6, 6D] service because the PBX recognizes the access code of LAST NUMBER CALLED
as the telephone number. In other words, the target number for STEP CALL is not the telephone number
dialed before LAST NUMBER CALLED, but the number dialed as the LAST NUMBER CALLED access
code. For example:
a.) Station A places a call to Station B (4000) by dialing “300”, which is the access code of LAST
NUMBER CALLED.

S-13 Step Call
Interactions (cont’d)
b.) Station A hears busy tone since Station B is busy.
c.) Station A dials “1” using STEP CALL.
d.) The PBX recognizes that “301” is dialed.
Programming
STEP 1:ASYD - System Data 1, Index 59, Bit 2. DID Busy Condition 0/1: No Tone/Busy Tone (Assign 1)
STEP 2:ASTD - STM 2, STS 6, ST 1 to restrict DID step call.

Serial Call S-15
S-15 Serial Call
General Description
This feature allows the Attendant to arrange for a recall from a station before releasing a Central Office call to that
station. When the station subsequently disconnects from the call, the Central Office party automatically rings back
to the Attendant. 
Operating Procedure
1. Answer the incoming Central Office call.
2. Extend the call to the desired station. 
3. Press the SERIAL CALL (SC) key; the HOLD lamp corresponding to the loop will light. 
4. The called station and incoming station are connected.
5. The called station hangs up; the HOLD lamp and the ATND lamp on the Attendant Console flash at 60
IPM. If the Attendant position is available, an audible indication will be provided.
6. Press the associated loop key to return to the incoming calling party.
Service Conditions
1. This service feature is effective only for incoming calls from external trunks. 
2. If the Attendant enters a loop that is already set up for SERIAL CALL, the service is automatically
cancelled.
3. SERIAL CALL (SC) is not provided for station-to-station calling. 
4. SERIAL CALL can be provided on a per-tenant basis.
5. SERIAL CALLING is allowed when a station is involved in an ATTENDANT CONTROLLED
CONFERENCE [A-2].
6. STATION MESSAGE DETAIL RECORDING (SMDR) [S-10]: The duration of the total call is recorded
on the last station call.
7. When the ATTENDANT LOCKOUT [A-5] feature is provided, the Attendant cannot reenter the
connection without being recalled.
8. This feature is not applicable for tandem connections.
9. In the Loop Release system, once this service is set, the attendant position enters the idle state, and the
established call is released from the loop, enabling all hooking services at the extension side. ASYD,
System Data 1, Index 186, bit 4 = 1.
10. The Attendant sets this service by pressing the SC key when the extension user answers. 
11. It is not possible to release this service once it is set.
12. If the operator presses the SC key before the called extension answers (Non-Delay mode service setting),
the external calling party receives a ringback tone, and the Attendant position enters the idle state.
13. In the Non-Delay mode service, setting the extension loop release does not occur until the called extension
answers, even though the Loop Release system is specified by the System Data setting (System Data 2
INDEX 2 b5 = 1). The operator is allowed to reenter the connection before the extension answers, though
the SERIAL CALL service remains set.
14. CALL PICKUP GROUP [C-7] feature can be used for answering a call handled by the operator in the
Non-Delay service setting mode. 
15. CALL FORWARDING-DON’T ANSWER [C-3] feature cannot be used if SERIAL CALL is set.

S-15 Serial Call
Service Conditions (cont’d)
16. SERIAL CALL termination is indicated to the Attendant by means of the HOLD or SC/RC lamp and
buzzer indication. ringback tone is sent to the external calling party up to the time the Attendant answers
the indicated serial call.
17. SC termination indication goes off if the external calling party is released before the Attendant answers
the indicated serial call (in case of TIE Line connection). 
18. Either the SC/RC key or the ANSWER key is used to answer a serial call if ASYD System Data 1, Index
186, Bit 4 is “1”.
19. SERIAL CALL service is automatically released when the operator answers the indicated serial call.
20. The Day-To-Night mode change does not interrupt the indication of serial call termination. 
21. Attendant supervision of a SERIAL CALL on the ATTENDANT CONSOLE [A-3] is provided via the
loop status lamps. After an incoming trunk call is extended to a station and the called station goes on-hook,
the Attendant is alerted by the flashing HOLD indicator lamp.
22. The following features are denied toward a line or trunk involved in a SERIAL CALL if ASYD, System
Data 1, Index 186, bit 4 = 0:
ATTENDANT CAMP-ON WITH TONE INDICATION [A-1]
ATTENDANT OVERRIDE  [A-7]
BUSY VERIFICATION  [B-3]
BOSS-SECRETARY OVERRIDE - D

EXECUTIVE RIGHT-OF-WAY [E-1, 1D]
23. When CALL WAITING - TERMINATING [C-12], CALL WAITING - ORIGINATING [C-31],
Attendant Camp-On, or Attendant Camp-On - CCIS is set to the station already engaged in a SERIAL
CALL, the following conditions occur:
a.) If the station answers the overriding call, the party formerly engaged in the SERIAL CALL is
placed on hold. When the station releases and does not return to the held call, the Attendant is
recalled.
b.) If the station does not answer the overriding call, Call Waiting or Attendant Camp-On is
activated.
Interactions
1. Features requiring the switch hook to be flashed are available. These include CALL TRANSFER-ALL
CALLS [C-11], CALL PICKUP [C-7, 30], CONSULTATION HOLD [C-17], and CALL HOLD [C-6] if
ASYD System Data 1, Index 186, Bit 4 is “1”.
2. EXECUTIVE RIGHT-OF-WAY [E-1], BUSY VERIFICATION [B-3], and ATTENDANT OVERRIDE
[A-7] are available towards a station/trunk involved in a Serial Call, if ASYD System Data 1, Index 186,
Bit 4 is “1”.
3. If a Serial Call is transferred to a second station, when the second station hangs up, the Serial Call will
return to the Attendant Console if ASYD, System Data 1, Index 186, Bit 4 is “1”.
Note:
The SC (Serial Call) key is the key right of the DEST key. The SC/RC (Serial Call Recall) key replaces the CCSA key

a single digit.
Operating Procedure
To access a desired feature, refer to the Operating Procedure section of that particular Feature Description.
Service Conditions 
1. When accessing SINGLE-DIGIT FEATURE CODES, consideration must be given to the overall
numbering plan of the particular system, unless timing start has been provided. 
2. Timing start is not available with this feature.
Interactions
1. For each feature with one-digit access, an entire number level is eliminated. Do not plan to have more than
one or two such features in a system. 
2. The corresponding feature cancel code does not have to be a single digit. 
3. TRUNK ANSWER ANY STATION [T-8], SPEED CALLING-SYSTEM [S-3], and DIAL ACCESS TO
THE ATTENDANT [D-2] are three applications for SINGLE-DIGIT FEATURE CODE.
4. The digit “*” or “#” can be used as the first digit of a trunk access code and can be used as a feature access
code.
Programming
STEP 1:ANPD - Reserve a number level for feature access. Assign Connection Indexes, CI = N, H, B; Normal
(N), Hooking (H), and Busy (B) (applicable to any feature assigned to this level). Assign NND in
accordance with a predetermined numbering plan. BLF is not in service. 
STEP 2:ASPA - Assign the Tenant and Access Code for the desired feature. Assign Connection Indexes, CI =
N, H, B; Normal (N), Hooking (H), and/or Busy (B). Assign the SRV = SSC (Service Code) or SSCA
(Service Code Appendix), and Service Feature Index SID or SIDA for the required feature. 
STEP 3:ASFC - Assign to the stations to receive this feature an SFC that allows the corresponding SFI.
