Centralized Attendant Service (CAS) C-20
Operating Procedure (cont’d)
Remote Hold:
1. The Attendant converses with a central office party.
2. The Attendant operates the SHF key; hears special dial tone.
3. The Attendant dials the Remote Hold access code (one or two digits); the central office party is placed in
the hold state at the satellite system, and the Attendant hears the hold confirmation tone (five, 50 msec.
bursts of 440 Hz).
4. The Attendant presses the RELEASE key to make the release link trunk available to serve another call.
5. If the central office party remains in the hold state for longer than the prefixed time, the satellite system
reconnects the central office party via the release link trunk.
6. Upon receiving the recall on the hold call, the ATTENDANT CONSOLE(s) [A-3] will display the
incoming CAS call by flashing the CAS lamp.
7. The Attendant answers the incoming CAS call by pressing the CAS or ANSWER key; hears the hold recall
identification tone (five, bursts of 440 Hz).
8. The Attendant is now able to complete the call.
Operator Call:
1. When an operator call code (one or two digits) is received from a station or TIE Line trunk in the satellite
system, an operator call is directed to the main system via release link trunks.
2. Upon receiving the incoming CAS call, the ATTENDANT CONSOLE(S) [A-3] will display the incoming
CAS call by flashing the CAS lamp.
3. The Attendant answers the incoming CAS call by pressing the CAS or ANSWER key; hears the operator
call identification tone (two, 100 msec. bursts of 440 Hz).
4. At the expiration of this tone, the Attendant converses with the calling party.
5. The Attendants procedure for serving this call is similar to that for an LDN call.
Call Transfer - Attendant:
1. After any call is completed to a satellite station, the called party station can call the Attendant in the main
system to transfer the calling party to another station in the satellite system. The operation of this feature
is similar to that of an operator call.
2. The Attendant answers the incoming CAS call by pressing the CAS or ANSWER key; hears the operator
call identification tone (two, 100 msec. bursts of 440 Hz).
3. After answering the call, the Attendant presses the SHF key, causing the satellite system to disconnect the
station that dialed the operator call code and connects to the calling party.
Night Service for the Incoming CAS Call in the Main System:
1. In night mode, the incoming CAS call is directed to a night station to be answered.
2. When the night station answers that call, the night station hears the identification tone depending on the
call.
3. The night station momentarily switch hook flashes; hears the special dial tone from the main system.
4. Dials the Flash Signal Sending access code (one or two digits); hears special dial tone.
5. After this, the operation of the night station is similar to that of the Attendant.
6. The night station must be provided with DTMF signaling.
Service Conditions
The following applies to a NEAX2400 IMX used at the main CAS location (Attendant location):
1. The number of Release Link Trunks (RLTs) is determined by overall satellite to main location traffic
requirements.

Page 188ND-70184 (E), Issue 3
C-20 Centralized Attendant Service (CAS)
Service Conditions (cont’d)
2. RLTs can be seized in one direction only; from the satellite PBX to the main PBX.
3. The Attendant cannot originate or INTER-POSITION TRANSFER [I-5] a call on an RLT.
4. The Attendant cannot extend an incoming CAS call to a station, trunk, or another Attendant in the main
system.
5. CALL PROCESSING INDICATION [C-8] is not provided to the Attendant serving the incoming CAS
call. 
6. The Attendant at the main PBX cannot connect RLT calls to main PBX station users.
7. The main PBX Attendant cannot busy verify a station in the satellite system.
The following applies to a NEAX2400 IMX used as a satellite location:
1. The number of station ports used will equal the number of RLTs required.
2. A call extended by an Attendant in the main system can be recorded on SMDR [S-10].
3. An optional ATTENDANT CONSOLE [A-3] may be provided at a satellite PBX to allow a local
Attendant to control access to WATS or FX trunks.
4. CAMP-ON [A-1] and Remote Hold are not provided for an operator call.
5. The NIGHT CONNECTION - FIXED [N-1] / FLEXIBLE [N-2] and TAS feature can be provided at the
branch location.
6. A NEAX2400 IMX can be equipped with 100 RLTs per hunt group.
7. FCCS link is not available for this service.
Interactions
1. Release Link Trunks are not used for voice calls between PBXs. Release Link Trunks cannot be
transferred to a station in the main system. TIE Lines must be installed for regular voice connection
between systems.
2. CAS systems have no effect on tandem connection, LCR(6)/LCRS(7), or any other trunking application.
3. The following applies to a system used at the main CAS location (attendant location): The Attendant
Console cannot originate or INTERPOSITION TRANSFER [I-5] a call on an RLT. The Attendant
Console at the main PBX cannot connect RLT calls to main PBX station users.
4. A NEAX2400 IMX can be equipped with 100 RLTs per STATION HUNTING [S-7, 8, 9] group. This is
a constraint of STATION HUNTING [S-7, 8, 9] and UNIFORM CALL DISTRIBUTION [U-1], not CAS.
5. Listed Directory Numbers (LDN) may be provided for the various satellite systems. Because these LDNs
will ring in only at the CAS key of the Attendant Console, indications to distinguish among the multiple
LDNs are not specifically available. However, the route number is displayed and can be used to distinguish
satellite systems.
6. During the Day mode of operation, if all RLTs are busy, incoming COT calls will wait and ringback tone
is sent to the calling party.
7. If the Attendant Console at the main system should switch hook flash to get dial tone from the satellite and
all ports are busy, reorder tone is sent to the Attendant Console. The Attendant can switch hook flash COT
party.
8. The CAS feature allows Attendant Console to be located at both the main and satellite locations. When
the satellite location goes to the Night mode, translations are available to connect incoming C.O. calls to
the RLT circuits. This is accomplished by the ACSI command and the NIGHT CONNECTION FIXED/
FLEXIBLE [N-1, 2] feature.

Interactions (cont’d)
9. When the Night stations are located at the satellite PBX and no Attendant Console is provided, a Night
key must be installed at the satellite location to activate night service. When the key is operated, the CAS
operations are suspended, and incoming calls are terminated at the NIGHT CONNECTION FIXED/
FLEXIBLE station(s) [F-1, 2] or via TRUNK ANSWER FROM ANY STATION [T-8]. When answered,
the Night station can transfer the call to the main location via the TIE trunks but not the RLT circuits. A
PA-D07 (Attendant Console) circuit card must be supplied to the satellite system.
10. PAGING ACCESS [P-1]: This feature allows the CAS Attendant to access paging equipment located at
the branch location upon answering an RLT call. See PAGING ACCESS [P-1] and MEET-ME PAGING
[M-1].
11. CODE CALLING ACCESS [C-21]: This feature allows the CAS Attendant Console to access CODE
CALLING equipment located at the satellite location upon answering an RLT call.
12. STATION MESSAGE DETAIL RECORDINGS [S-10]: SMDR is provided for calls extended by a CAS
Attendant Console.
Programming
Main System
STEP 1:ASYD - System Data 1, Index 150. Assign data 00H. This is the guard timer between the Attendant
Console switch hook flash and the dialing of digits.
System Data 1, Index 151. Assign data 00H. This allows a 480 msec. SHF. Timer Class is given as 32
msec. For variable Hooking values, adjust the Miscellaneous Timer Class in Bit 0-3.
System Data 2, Index 13, Bit 1. Assign a data “0” for a Main system. This Bit applies to the PFT circuit
card. This application is not common.
STEP 2:ARTD - Assign the CAS routes (Release Link Trunks, RLT) in ARTD as follows. Be sure to assign
CDN 6:TCL as data “7”, CA line.
RT:1
1-OSGS :2 2-0NSG :3 5-TF :3 6-TCL :7*7-L/T :1
15-LSG :5**
STEP 3:AT R K - Program the LEN of the RLT trunks. These trunks must be 16COT circuit cards.
STEP 4:MBTK - Make idle the Release Link Trunk.
Note 1:
*This Bit will provide a Dterm trunk display when used as a Night Station.
Note 2:
**This Bit is used when the 8TLT card, Issue 14 circuit card is used at the Main PBX location for the Release Link
Trunks. At the satellite location, an 8TLT card is used for Release Link Trunk (RLT). If a 16COT card is used as the
RLT at the main location, assign LSG as data 0 Loop.
STEP 3:AAKP - To provide the Attendant Console with a FLASH key, the assignment of Attendant Console
Key Pattern (AAKP) must be programmed. Assign the ATN: Attendant Number (TRK No. for RTE
901); KYN = 5; and FUNC = 1, CAS Line. (If this data is not assigned, CAS trunks will not ring into
the Attendant Console.)
STEP 4:ANND - For the outgoing connection parameter, OG; assign Route Number and the Number of
Necessary Digits. The NND is the number of digits in the satellite switches’ station numbering plan.
Night Station - CAS
STEP 1:ANPD - Reserve a number level for feature access.
STEP 2:ASPA - Assign an access code to the (Hooking (H)), SRV = SSC (Service Code); SID = 43. Assign
for a Connection Status Index (CI) of Hooking (H).
STEP 3:ACFR - Assignment of Call Forwarding Restriction. Allow Call Class Index (CCI) 14, CAS Trunk
Main, a Transfer Service Feature Index (TSFI) of 5, TAS. 
						

							NEAX2400 IMX Feature Programming Manual
Page 190ND-70184 (E), Issue 3
C-20 Centralized Attendant Service (CAS)
Programming (cont’d)
STEP 4:ACSI - Assign the Incoming CAS Route and Trunk to the Night Station and Tenant number. Assign
the CSI = 4 for Night Connection.
TAS
STEP 1:ANPD - Reserve a number level for feature access.
STEP 2:ASPA - Assign an access code to TRUNK ANSWER ANY STATION, SRV = SSC (Service Code);
SID = 16. Assign for a Connection Status Index (CI) of Normal (N).
STEP 3:ACFR - Assignment of Call Forwarding Restriction. Allow Call Class Index (CCI) 14, CAS Trunk
Main, a Transfer Service Feature Index (TSFI) of 5, TAS.
STEP 4:ATA S - Assign the TAS circuit to the system. Refer to TRUNK ANSWER FROM ANY STATION
[T-8] for details.
Note:
A second call will go to TRUNK ANSWER FROM ANY STATION if the first call is being answered by the Night station.
Satellite System
STEP 1:ASYD - System Data 1, Index 149. Assign 00H for Recall Timer to Attendant Console at the main
system location. This value is 30 seconds.
System Data 2, Index 11, Bit 7. Will DIT park in a busy station Queue? 0/1: Yes/No, it will be rerouted
to the Attendant Console. Assign data “0” for Queuing.
System Data 2, Index 13; Bit 1. Assign data “1” for satellite system.
STEP 2:ANPD - Reserve a number level for feature access. Assign for Normal (N), Hooking (H), and Busy
(B). Assign NND in accordance with a predetermined numbering plan. Reserve a number level for
station numbers. If the satellite system does NOT have an Attendant Console, 0 can be used as a
station number. If not, consider a numbering plan for the Release Link Trunks that will be assigned to
the stations assigned a TEC = 15.
STEP 3:ARSC - Construct a Route Restriction Class that allows a direct connection to all incoming trunks that
will be served by the Attendant Console at the main system location. Assign via Route Restriction
Index, RRI 1, Direct Connection on Incoming Trunks.
STEP 4:ASFC - Construct a Service Feature Class that allows Station Message Detail Service SFI = 14. Do
not provide CALL FORWARDING [C-2, 3, 5].
STEP 5:ASDT - Assign ports of the 8TLT card, Issue 7* that receive the Release Link Trunks as TEC 15. The
RSC assignment should allow a direct connection with all required incoming trunks. Allow these
trunks via Route Restriction Index (RRI) = 0 & 1. The SFC assigned is separately constructed and can
include SFI: 14, SMDR. See STATION MESSAGE DETAIL RECORDING (SMDR) [S-10]. When
assigning station numbers, keep in mind that one of these stations will be the lead station in a UCD
group and that station number will be used by the satellite stations to access the Attendant Console at
the main system location. To keep the user from becoming confused when a different number appears
on the LCD display than the one dialed, make the station numbers appear as sequential circuit numbers
such as 100, 101, 102, etc.
Note:
If a 16COT card is used at the main location for the RLTs, 16LC cards are used at the satellite location.
STEP 6:ASHU - Assign the Release Link Trunk stations to a UCD group. See UNIFORM CALL
DISTRIBUTION [U-1]. One station number will be designated as the lead station. This number will
simulate Dial Access to Attendant. Also, incoming trunk calls will be distributed among the available
Release Link Trunks evenly. ASHC command may also be used, STATION HUNTING-CIRCULAR
[S-7].
STEP 7:ACSI - Assign the Incoming Satellite trunks to be answered at the Main system CSI = 3, Direct In
Termination, Day and Night Mode. Then assign the stations programmed above. This ties incoming
trunks to the PA-4ODTs.

Programming (cont’d)
STEP 8:ACFR - Assignment of Call Forwarding Restriction. Upon determining which types of Call Class
Indexes (CCI) will be answered at the Main system, such as LDN (DDD), WATS, FX; allow those
CCI a Transfer Service Feature Index of 15, CAS Line.
STEP 9:ACSA - (Optional) Use this command rather than ACSI if CAS operation is desired in Day mode, and
if incoming trunks are to stay at the satellite and be answered by TAS or a NIGHT CONNECTION -
FIXED/FLEXIBLE [F-1/2] station in Night mode.

Call Forwarding-Intercept / Announcement C-25
C-25  Call Forwarding-Intercept / Announcement
General Description
This feature provides for interception of STATION-TO-STATION [S-11], DIRECT INWARD DIALING [D-8],
Attendant-to-Station and CCSA [C-14] calls that cannot be completed (unassigned station, level, etc.). These calls
are automatically routed to a recorded announcement informing the caller that an inoperative number was reached
and giving the Listed Directory Number for information.
This feature permits a station-originated call, upon encountering a restricted outgoing number, to automatically be
routed to a recorded announcement informing the caller that the dialed number is restricted for this station.
This feature permits a station-originated call, upon encountering a trunk busy condition, to automatically be routed
to a recorded announcement informing the caller that all the outgoing trunks are busy.
Operating Procedure
No manual operation is required, once this feature has been programmed in system data.
Service Conditions
1. CALL FORWARDING-INTERCEPT / ANNOUNCEMENT requires one of the following hardware
alternatives:
a.) Central Office Trunk (COT) or 2W E&M trunk and an announcement machine, or
b.) Digital Announcement Trunk (DAT).
2. If the outside party or Attendant forgets to hang up, the system will automatically disconnect in 30 seconds
(provided this is programmed in system data). If no disconnect timing is programmed, the outside party
will control disconnect.
3. This feature is provided on a per-tenant basis.
4. The following call conditions, which cannot be completed, can be routed to intercept:
a.) vacant level,
b.) unassigned telephone number.
5. Only one common message can be provided for the different intercept conditions.
6. There is no method by which to exempt individual DID, CCSA, and TIE Trunks from intercept.
7. A station dials the LEAST COST ROUTING [L-5] access code and then an outside number. If that outside
number is not listed in LEAST COST ROUTING [L-5] tables (Outgoing Routing Patterns, OPR), the call
will be routed to an intercept announcement.
8. If a different message is required for each of the three intercept conditions, three trunks or three
announcement machines must be provided.
When encountering a Restricted Route:
9. This service feature is valid when station to outgoing trunk connection is restricted.
10. This feature is applied equally to all trunk routes in the system. It cannot be denied to some routes and
available to other routes.
11. This service is valid when a call is redirected to an OG trunk via CALL FORWARDING-OUTSIDE
[C-28]. The announcement will be heard when the calling station is also a restricted station.
12. This service is not valid for TRUNK-TO-TRUNK CONNECTION [T-10] when the called station has set
CALL FORWARDING - OUTSIDE [C-28] via DID or TIE Trunk.
13. This service is not valid for outgoing calls that do not go out when all trunks or senders are busy.
When encountering all trunks busy:
14. This service feature is valid for outgoing station-to-trunk or tandem trunk-to-trunk connections.

C-25 Call Forwarding-Intercept / Announcement
Service Conditions (cont’d)
15. Automatic OUTGOING TRUNK QUEUING [O-2], OFF-HOOK QUEUING [O-7] and ROUTE
ADVANCE [R-6] are mutually exclusive with this feature. These features take priority over OUTGOING
TRUNK BUSY - ANNOUNCEMENT [O-21].
16. ANNOUNCEMENT SERVICE is provided to FCCS nodes that have no announcement trunk using the
trunk in the remote node.
17. When CALL FORWARDING - INTERCEPT/ANNOUNCEMENT [C-25] or CALL FORWARDING -
INTERCEPT / ANNOUNCEMENT - ATTENDANT [C-75] is used in an FCCS network, the additional
data shown below is required.
a.) the logical route number should be applied to the physical route that is provided the service.
b.) the restriction of route-to-route connection between FCCS nodes should be released.
18. When using the FCCS network, CALL FORWARDING-INTERCEPT / ANNOUNCEMENT [C-25] or
CALL FORWARDING - INTERCEPT / ANNOUNCEMENT-ATTENDANT [C-75] is not provided for
the incoming call using AUTOMATED ATTENDANT [A-82], DIRECT-IN TERMINATION [D-7], or
REMOTE ACCESS TO SYSTEM [R-2].
19. When using the FCCS network, the call forwarding for an incoming call routed to a dead level or an
unused number has priority over the announcement service for the incoming call.
Interactions
1. Each route connected to an announcement machine is also an EQP. The same route can be assigned as
different EQP’s. However, it is best to separate EQP functions by route.
2. 8TLT, 16 COT, or 4DAT card may be used.
Programming
STEP 1:ACFO - Enable this feature by allowing CF = 3: CALL FORWARDING - INTERCEPT/
ANNOUNCEMENT. The CFI parameter will come up for assignment. An Attendant Console may be
programmed so that intercepted calls will terminate at the CALL FORWARD INTERCEPT key. If no
assignment is made, the NEAX2400 IMX program goes to the AAED command for announcement
trunk information because the destination of the transfer is a trunk and not a station or Attendant
Console.
STEP 2:ARTD - Assign the announcement route as shown below:
RT: 1
1-OSGS :2 2-ONSG :3 5-TF :1 6-TCL :1 7-L/T :1
8-RLP :2 15-LSG :0*
Note:
*If a PA-8TLTR is used, assign as 5, E & M.
STEP 3:AT R K - Assign the LENs, Announcement Trunk Route Number, Trunk Number, and Tenant Number.
STEP 4:MBTK - Assign the Make Idle status to the Announcement Trunk.
Note:
If supervision is required, use the first two circuits of the 16COT circuit card. Move the switch on the 16COT to PGT.
STEP 5:ARRC - If TIE Line or REMOTE ACCESS TO PBX [R-2] connection to the ANNOUNCEMENT
SERVICE Trunk is required, allow trunk-to-trunk connection using ARI-D-RES, Direct Connection.
