A-4 Attendant Keypad
A-4 Attendant Keypad
General Description
This feature permits the Attendant to dial all calls from the ATTENDANT CONSOLE [A-3] via a push-button PAD.
Operating Procedure
Refer to the description of each service feature related to Attendant Console. 
Service Conditions
1. Whether the NEAX2400 IMX is equipped with DP or DTMF trunk lines, signals from the ATTENDANT
KEY PAD will be converted.
2. Via the key pad, the Attendant may originate calls, process incoming calls, and activate various service
features. They are as follows:
a.) Pushbutton Calling [P-4]
b.) Pushbutton Calling - Attendant only [P-5]
c.) Rotary Dial Calling [R-5]
3. The ATTENDANT KEY PAD generates DC signals, which in turn are converted to either DP or DTMF
signals by the Attendant interface circuit.
4. The key pad consists of twelve (12) keys used to generate digits 0 through 9, plus the “*” and “#” keys.
Programming
ASYD - System Data 2, Index 2, bit 1. This assignment will determine type of sender used by the
Attendant Console, either dial pulse or push-button, 0/1: DP/PB. The Attendant Console must first be
provided.
System Data 1, Index 134, RAM data is 32H, 4 seconds. This is the interdigit timer for the register/
sender circuit on the ATI card. For normal operation, no assignment is required via the MAT.

Attendant Lockout A-5
A-5 Attendant Lockout
General Description
This feature denies an Attendant the ability to re-enter an established trunk/station connection without being recalled
by the station.
Operating Procedure
No manual operation is required once this feature has been programmed into system data.
Service Conditions
1. This feature is, by definition, mutually exclusive with:
ATTENDANT OVERRIDE [A-7]
BUSY VERIFICATION [B-3]
2. Lockout is inoperative on TRUNK-TO-TRUNK CONNECTION [T-10] when the release signal is not
provided from the distant end.
3. Lockout is not used unless the feature is provided which gives 2-party hold capability. Without this
capability, the completed call is removed from the ATTENDANT CONSOLE [A-3] loop, so the
Attendant cannot reenter for assistance or any other purpose.
Interactions
1. ATTENDANT OVERRIDE [A-7]: In those cases where answer supervision is returned on TRUNK-TO-
TRUNK CONNECTIONS [T-10], the Attendant can override the busy condition by using the
ATTENDANT OVERRIDE [A-7] feature.
2. TRUNK-TO-TRUNK CONNECTION [T-10]: Privacy is automatically disabled for TRUNK-TO-
TRUNK calls, if the release signal is not provided from the distant end.
3. SPLITTING [S-4]: The Privacy feature works with the SPLITTING [S-4] feature to cause automatic
splitting.
4. Switched Loop Operation: Call processing is modified so that pressing a loop key does not cause the
Attendant to be bridged on an established call unless the Attendant is recalled. An exception is a TRUNK-
TO-TRUNK CONNECTION [T-10] when the release signal is not provided from the distant end.
5. ATTENDANT-CONTROLLED CONFERENCE [A-2]: When the Attendant reenters a conference
connection to answer a recall, only the Attendant and the recalling station are connected together.
Programming
Per-Route Basis:
ARTD - Assign CDN 44:PRV as a “1”, Line Privacy.
Per-Station Basis:
ASFC - Assign “0” to SFI 4 and SFI 11 to the SFC assigned to the stations.
Per-Tenant Basis:
ASYD - System Data 2, Index 0, bits 3, 4 & 5. Assign data “0”.

A-6 Attendant Loop Release
A-6 Attendant Loop Release
General Description
This feature allows an ATTENDANT CONSOLE loop to become available for a second call as soon as the
Attendant has directed the first call to a station, even if that station does not answer.
Operating Procedure
1. ATTENDANT CONSOLE indicates an incoming call. 
2. Press the ANSWER or INCOMING CALL INDICATION [I-2] key.
3. Dial the desired telephone number; receive ringback tone.
4. Before the station answers, press the RELEASE key.
5. The loop is now available for another call.
Service Conditions
1. Unanswered calls will be routed to the Attendant within the predetermined time via AUTOMATIC
RECALL [A-8]. See VARIABLE TIMING PARAMETERS [V-1].
2. If all Attendant Loop circuits are busy when AUTOMATIC RECALL [A-8] is activated, the system will
automatically scan for an idle Loop every 8 seconds.
3. A maximum of six calls (one per Loop) may be released simultaneously from any single ATTENDANT
CONSOLE.
4. This feature provides the Attendant with the equivalent of 12 switching loops.
5. In a MULTIPLE CONSOLE OPERATION [M-4], the Attendant who initiated the Loop Release will be
recalled.
6. ATTENDANT LOOP RELEASE is only applicable to incoming trunk calls extended to an unanswered
station or busy station (Camped-On).
7. Calls that are held by the Attendant, using the HOLD key, cannot be released from the ATTENDANT
CONSOLE [A-3]. These calls remain on the switched loop until they are either extended by the Attendant
or abandoned by the calling party.
8. After the ATTENDANT LOOP RELEASE is activated, the Attendant cannot interact with the call until
altered by the AUTOMATIC RECALL [A-8] feature.
9. ATTENDANT CAMP-ON: This feature, when active, permits the Attendant to CAMP-ON [A-1] to a
busy called station. Upon ATTENDANT CAMP-ON WITH TONE INDICATION [A-1], the Attendant
may release the call from the ATTENDANT CONSOLE [A-3].
Interactions
1. The Attendant Console must first be provided.
2. ATTENDANT LOOP RELEASE and CALL FORWARDING - DON’T ANSWER [C-3] on calls
extended to a station via the Attendant Console (System Data 2, Index 6, Bit 7) are mutually exclusive.
3. ATTENDANT LOOP RELEASE is only applicable to incoming station or trunk calls extended to an
unanswered station or busy station. See ATTENDANT CAMP-ON WITH TONE INDICATION [A-1].
4. Calls placed on CALL HOLD [C-6] by the Attendant Console are not released from the console. These
calls remain on the loop until they are either extended by the Attendant or abandoned by the calling party.
5. A maximum of six calls per console can be released and stored in the system memory. A seventh call
extended (unanswered/camped-on) will remain in the loop.

Attendant Override A-7
Service Conditions (cont’d)
4. Each tone burst is 0.08 seconds in duration and is used to alert both parties that the Attendant is overriding
the conversation.
5. This feature can be denied on DICTATION [D-3] and PAGING [P-1] connections by assigned ARTD
data.
6. It is possible, via System Data, to completely disable the sending of warning tone during an ATTENDANT
OVERRIDE connection. Normally the two burst Warning Tone is sent when the ATTENDANT
OVERRIDE connection is initiated and then is repeated approximately every 15 seconds. The initial tone
burst is also disabled. If the trunk is connected to a D
term, the display is as follows:
After 5 seconds, the display returns to the normal Conference display, CONF. 
7. ATTENDANT OVERRIDE is temporarily denied and reorder tone heard if any of the following features
are active:
a.) EXECUTIVE RIGHT-OF-WAY [E-1]: If the called trunk is connected to a line on which
EXECUTIVE RIGHT-OF-WAY is being used.
b.) Trunk Restriction: If the called tie trunk was routed to reorder tone as a result of trunk restriction.
c.) SPECIAL DIAL TONE [S-2]: If the called trunk is on hold.
d.) ATTENDANT CAMP-ON WITH TONE INDICATION [A-1]: If the called trunk is camped-on
to a busy station.
e.) SERIAL CALL [S-15]: ATTENDANT OVERRIDE is denied to the parties held on the console.
f.) ATTENDANT INTERACTION: During the normal operation of PBX features, situations may
arise whereby a trunk may be connected to an ATTENDANT CONSOLE [A-3]. While the trunk
is connected to the ATTENDANT CONSOLE [A-3] or is in queue at an ATTENDANT
CONSOLE [A-3], the Attendant at the Console or an Attendant at any other Console (when
multiple consoles are provided) is not allowed to bridge on the connection. The trunk must be
connected to a station in a talking mode in order for the ATTENDANT OVERRIDE feature to
function.
8. The ATTENDANT CONSOLE cannot specify a trunk accommodated in a different node in the FCCS
network.
Interactions
1. With ATTENDANT OVERRIDE, the following trunk types may be verified (busy or idle status):
a.) One-way incoming trunks
b.) One-way outgoing trunks
c.) Bothway trunk
2. Trunks in a station-to-trunk connection or TRUNK-TO-TRUNK CONNECTION [T-10] can be verified
when busy. 
3. ATTENDANT LOCKOUT [A-5]: The Attendant is prevented from overriding a busy trunk which is
connected to a loop held at the Attendant Console. Since the lockout feature applies only to calls held on
an Attendant Console loop, ATTENDANT OVERRIDE of those trunks will be denied and the Attendant
will hear reorder tone.
4. CALL FORWARDING - ALL CALLS [C-5], BUSY [C-2] or DON’T ANSWER [C-3]: If an Attendant
attempts to busy verify an idle or busy station line that has activated the Call Forwarding feature, busy
verification of the destination station will occur. If an Attendant attempts to busy verify an idle or busy
station which is call forwarded to the Attendant Console, ATTENDANT OVERRIDE will not be allowed. OPE BV

Automatic Recall A-8
A-8 Automatic Recall
General Description
This feature works as a timed reminder. When a call handled by the Attendant remains on hold, camped-on, or
ringing unanswered for a fixed interval, the Attendant is automatically alerted.
Operating Procedure
No manual operation is required.
Service Conditions
1. AUTOMATIC RECALL [A-8] timing is preset in System Data at 30 seconds. See VARIABLE TIMING
PARAMETERS [V-1] for other selectable timing choices.
2. If the Attendant reenters a held or camped-on trunk, timing is reset when the trunk is returned to the
previous condition.
3. The Attendant Console buzzer will sound to signal Recall, provided no calls are being processed, in
addition to the standard visual indication for incoming calls.
4. This feature is denied on INCOMING CENTRAL OFFICE CALL TO TIE LINE CONNECTION [I-3].
5. When an Attendant answers AUTOMATIC RECALL, either the dialed number or the calling telephone/
trunk number can be displayed (on System Data basis).
6. The indication on the ATTENDANT CONSOLE [A-3] follows DIGITAL DISPLAY - STATION [D-5].
When the dialed number (destination) is displayed, the display is as follows:
Tenant Number: Blank Space 
Trunk Route Restriction Class: Blank Space
Telephone Number: Dialed Number (Last Digits)
Interactions
1. This feature is available on calls extended to a branch PBX via a CENTRALIZED ATTENDANT
SERVICE [C-20] (CAS) position.
2. System Data 2, Index 6, Bit 7. On a per-tenant basis, allow this Bit for CALL FORWARD - DON’T
ANSWER [C-2] via the Attendant Console. During this operation, the call will ring at the called station
for the time interval set in System Data 1, Index 141 (ASYD 145 must be longer than 141). The call is then
forwarded and rings at the forwarded station for the time interval set in Index 145. If the call is still not
answered, it will be recalled to the Attendant Console via the AUTOMATIC RECALL feature.
3. System Data 1, Index 70, Bit 0 (Called Number Display). This Bit does not affect the display on the
Attendant Console for recalled calls. It is used for DIDs that have call forwarded to the Attendant or if the
Attendant reenters the loop on an extended call before AUTOMATIC RECALL has taken place.
4. When a trunk call recalls back to the Attendant Console, the destination telephone number will display,
and the SOURCE (SRC) LED will be lit. By pressing the SRC key, the display will change to the
originating route and trunk number. By pressing the DEST key, the display will change to the destination
station.
5. The station will continue to ring even as the call recalls to the Attendant Console. If the station should
answer at the same time the Attendant answers the recalling call, a three-way conversation will take place
(if conferencing is allowed and a conference card is programmed and installed). The Attendant can press
the SRC, DEST, or TALK keys to achieve the desired conversation or press the RELEASE key to get out
of the conversation.

A-8 Automatic Recall
Programming
ASYD - System Data 1, Index 145. Timer Class 1 = 2 second. 
For normal operation, assign 00H [RAM data is 94H]. Any call that uses AUTOMATIC RECALL
keeps one of the Attendant Console switched loops busy. Since there are six loops per Attendant
console, the maximum use of this feature is limited to that number. The AUTOMATIC RECALL
interval (normally set for 30 seconds) is a system option (System Data 1, INDEX 145) and can be
varied from two seconds to two minutes, in increments of two seconds. 
System Data 1, Index 73, Bit 6 = 0.
