Attendant Camp-On with Tone Indication - CCIS A-45
Operating Procedure (cont’d)
5. Stations (a) and (b) both go on-hook (Note 2); (b) is rung, and (c) receives ringback tone.
6. Station (b) answers; Station (b) and Subscriber (c) are connected with each other.
Note 1:
If the Attendant presses the BV key instead of the RELEASE key, the Attendant bridges into the Station (b) side and,
as a result, a three-way connection is set up. In this case, both (a) and (b) are bridged into the connection. The
Attendant sets Camp-On by pressing the RELEASE key. 
Note 2:
Instead of on-hook by Stations (a) and (b), if (b) switch hook flashes and dials the Call Hold Access Code, (b) can
answer Subscriber (c) (C.O.line party), and (a) is held on the line.
If (b) switch hook flashes and dials the Call Hold Access Code once again, (b) can return to the connection with (a).
In this case, Subscriber (c) is held on the C.O.line. 
Service Conditions
1. Only one incoming call can be camped on to a particular station at any given time. Multiple CAMP-ON
is not allowed.
2. Calls that remain camped-on for longer than the predetermined time will initiate AUTOMATIC RECALL
- CCIS [A-71]. 
3. CAMP-ON may be denied if the busy station is: 
a.) Dialing or in the LINE LOCKOUT [L-3] mode.

Attendant-Controlled Conference - CCIS A-46
A-46 Attendant-Controlled Conference - CCIS
General Description
This feature allows the Attendant to establish a conference among as many as eight parties. The conference group
can consist of any combination of stations and/or trunks in a CCIS network.
Operating Procedure
To activate ATTENDANT-CONTROLLED CONFERENCE - CCIS:
1. A station calls the Attendant to request a conference.
2. The Attendant connects the calling station to the conference leader by dialing the circuit number of the
conference leader connected to the Conference Unit. 
3. The Attendant sequentially calls all desired parties and connects by pressing START, dialing the pilot
number of the conference, and pressing RELEASE. 
Using the MMCB:
4. When all parties are connected, the conference leader with a push-button telephone can dial digit “0” to
prevent additional stations from entering the conference group, thereby assuring privacy. If the leader
presses “0” again, more parties can be added.
5. If the conference leader dials digit “#”, all conferees will be disconnected. Otherwise, the conference is
terminated only after all parties have hung up. 
Using the PA-CFTB:
6. When all parties are connected, the conference leader with a push-button telephone can dial digit “0” to
prevent additional stations from entering the conference group, thereby assuring privacy. If the leader
presses “0” again, more parties can be added.
7. If the conference leader dials digit “#”, all conferees will be disconnected. Otherwise, the conference is
terminated only after all parties have hung up.
For either:
8. To release from a conference circuit individually, a user hangs up. The remaining conferees can continue
without interruption.
Service Conditions
1. Conference Units are designed to provide adequate amplification, but the condition of the Central Office
connections will affect transmission.
2. Conference Unit extension numbers should be placed in a STATION HUNTING-TERMINAL [S-9]
group. Only the Pilot number of this group should be published.
3. Each Conference Unit can provide up to an eight-party conference. 
4. Override services, such as BUSY VERIFICATION [B-3] [B-9], ATTENDANT OVERRIDE [A-7] or
EXECUTIVE RIGHT-OF-WAY [E-1] [E-8], are denied to stations engaged in a conference call.
5. The following additional hardware is required:
a.) External Conference Unit MMCB, Model No.37008
b.) PA-16LCBE Circuit Card
6. The PA-CFTB circuit card may be used rather than the external Conference Unit MMCB. The MMCB
also requires a PA-16LC that is not required by the PA-CFTB.
Interactions
1. The Attendant Console must first be provided.  
						

							NEAX2400 IMX CCIS Features and Specifications

A-46 Attendant-Controlled Conference - CCIS
Interactions (cont’d)
2. NEC provides a PA-16LCBE circuit card that provides momentary-open for all 16 circuits. This is
required to provide a release signal when line circuits are connected to external equipment such as
conference and page units. This keeps reorder tone from being sent to the Conference Unit. 
3. The last port of a PA-16LCBJ/PA-16LCBL provides battery reversal upon release. Therefore, when a
station disconnects, reorder tone is not returned to the external Conference Unit.

Automatic Recall - CCIS A-71
A-71 Automatic Recall - CCIS
General Description
This service feature works as a time reminder. When an attendant-handled call through CCIS 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 timing is preset in System Data at 30 seconds. See the VARIABLE TIMING
PARAMETER [V-1] for other selectable timing choices.
2. If the attendant re-enters a held or camped-on trunk, timing is reset when the trunk is returned to the
previous condition. 
3. In addition to the standard visual indication for incoming calls, the ATTENDANT CONSOLE [A-3]
buzzer will sound to signal RECALL, provided no calls are being processed.
4. This feature is denied on INCOMING CENTRAL OFFICE CALL TO TIE-LINE CONNECTION [I-3],
except in the following conditions:
5. When the incoming signaling is a loop-start.
6. When ATTENDANT LOOP RELEASE [A-6] is activated. 
7. When an Attendant answers AUTOMATIC RECALL - CCIS [A-71], the dialed number of the calling
station/trunk number can be displayed (as programmed in System Data). 
8. The indication on the Attendant Console follows DIGITAL DISPLAY-STATION [D-5]. When the dialed
number is displayed, the display is as follows:
a.) Tenant Number: Blank Space 
b.) Trunk Route Restriction Class: Blank Space 
c.) Telephone Number: Dialed Number (Last Digits). 
9. AUTOMATIC RECALL - CCIS will appear on the attendant’s HOLD key.
Interactions
1. This feature is available on calls extended to a branch PBX via a CENTRALIZED ATTENDANT
SERVICE (CAS) [C-20] position.
2. System Data 2, Index 6, Bit 7. On a per-tenant basis, allow this Bit for CALL FORWARDING-DON’T
ANSWER [C-47] 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. 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 AUTOMATIC RECALL [A-8].
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 DID’s that have call forwarded to the Attendant, or
should the Attendant re-enter the loop on an extended call before AUTOMATIC RECALL [A-8] 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 Destination (DEST) key, the display will change to the
destination station.

A-71 Automatic Recall - CCIS
Interactions (cont’d)
5. The station will continue to ring, even as the call recalls to the Attendant Console. When conference is
allowed and a conference card is programmed and installed, if the station should answer at the same time
the Attendant answers the recalling call, a three-way conversation will then take place. 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.
6. Station calls extended by the Attendant to another station within the same system (node) will recall to the
Attendant. Station calls extended by the Attendant over CCIS will not recall. Trunk calls will recall in both
instances.
