Centralized Attendant Service (CAS) C-20
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.

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].

C-25 Call Forwarding-Intercept / Announcement
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.

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.
