Trunk Answer from Any Station - CCIS T-27
T-27 Trunk Answer from Any Station - CCIS
General Description
This feature allows any station not restricted from incoming calls to answer incoming calls when the network is in
Night mode.
When this feature is activated, incoming Central Office calls will activate a common TRUNK ANSWER FROM
ANY STATION (TAS) signal. By dialing a specified code, any station may answer the call and extend it to any
other station in the CCIS network using CALL TRANSFER - ALL CALLS - CCIS [C-50].
Operating Procedure
To answer an incoming call
1. The TAS signal sounds indicating an incoming call.
2. Lift the handset and receive dial tone.
3. Dial the TAS access code; the incoming call is connected.
Service Conditions
1. An incoming call terminating in the Night mode will be forwarded to the TAS equipment of the
terminating node.
2. An incoming call to the main node in the Night mode will not be forwarded to TAS equipment in a satellite
node through the CCIS network. Therefore, the main node must provide TAS equipment for incoming
Central Office calls.
3. When Night mode is set at the main node, satellite nodes not equipped with an ATTENDANT CONSOLE
[A-3] can automatically be set to the Night mode by CENTRALIZED DAY/NIGHT MODE CHANGE -
CCIS [C-56] service.
4. A TAS indicator can be provided for each node's incoming trunks.
5. An incoming call terminating in the Night mode will have the following order of priority:
a.) NIGHT CONNECTION - FLEXIBLE - CCIS [N-16],
b.) NIGHT CONNECTION - FIXED - CCIS [N-15],
c.) TRUNK ANSWER FROM ANY STATION - CCIS [T-27]. Incoming calls will overflow to TAS
[T-27], if this feature is provided, when the NIGHT CONNECTION FIXED/FLEXIBLE [N-1]
[N-2] [N-15] [N-16] stations are busy.
6. TAS indication will be activated for the LDN, WATS, FX, CCSA incoming calls.
7. TAS indication can be provided on a TENANT [T-12] basis.
8. Individual stations can be denied access to this feature via CLASS OF SERVICE - INDIVIDUAL [C-15].
9. If the system is changed to the Day mode while a TAS call is being indicated, a call terminating at a node
without an ATTENDANT CONSOLE [A-3] will not be transferred through the CCIS network to an
ATTENDANT CONSOLE [A-3].
10. This feature is also referred to as Universal Night Answer (UNA).
11. The TAS indicator must be locally provided.
12. All ATTENDANT CONSOLES [A-3] assigned to handle calls for a particular group of stations (whether
or not they belong to the same TENANT [T-12]) must have NIGHT CONNECTION [N-15, 16] set before
this feature will be activated.
