T-8 Trunk Answer from Any Station (TAS)
T-8 Trunk Answer from Any Station (TAS)
General Description
This feature allows any station (except one with incoming restrictions) to answer incoming calls when the system is
in Night Mode. Incoming exchange network calls will activate a common alert (TAS) signal at the customer’s
premises. By dialing a specified code, any station may answer the call and then extend it to any other station using
CALL TRANSFER-ALL CALLS [C-11].
Operating Procedure
1. TAS signal (bell, buzzer, etc.) sounds.
2. Lift the handset, receive dial tone.
3. Dial the specified TAS access code.
4. Connection to incoming call is completed.
Service Conditions
1. An incoming call that terminates in the Night mode will have the following priority:
a.) NIGHT CONNECTION-FLEXIBLE [N-2]
b.) NIGHT CONNECTION-FIXED [N-1]
c.) TRUNK ANSWER FROM ANY STATION (TAS) [T-8]
2. TAS indication will be activated for the following incoming calls:
a.) Listed Directory Number
b.) Foreign Exchange
c.) WATS
d.) CCSA
3. All consoles 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-1,2] set before this feature will be
activated.
4. The TAS indicator can be provided on a per-tenant basis.
5. The TAS indicator must be locally-provided.
6. This feature is sometimes referred to as Universal Night Answer (UNA).
7. Individual stations may be denied access to this feature via CLASS OF SERVICE-INDIVIDUAL [C-15].
8. If the system has changed to Day mode while a TAS call is being indicated, the ATTENDANT CONSOLE
[A-3] can be connected to this call.
9. Only one TAS per Tenant can be assigned as the TAS signalling port.
Interactions
1. For TAS to operate, an ATI circuit card is required, and the system must be in the Night mode, depending
on the type of Attendant Console system that is in service. Exercise care when setting the resistance value
via switch settings on the ATI circuit card.
2. TENANT SERVICE [T-12]: Only one TAS circuit may be assigned per tenant.
3. NIGHT CONNECTION-FIXED/FLEXIBLE [N-1, 2]: TAS can be used in conjunction with NIGHT
CONNECTION-FIXED/FLEXIBLE [N-1, 2]. When the Night Connection station(s) is busy, incoming
calls are directed to TAS.
