Trunk Answer from Any Station (TAS) T-8
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.

Interactions (cont’d)
4. CALL TRANSFER-ALL CALLS [C-11]: A station answering a call via the TAS feature will have access
to the transfer feature. 
5. CENTRALIZED ATTENDANT SERVICE (CAS) [C-20]: TAS may be installed at either the Main site
only or at both the Main and Satellite sites. Operations at either site are the same as TAS installed in a non-
CAS system. The Satellite system must have a means of placing the system into Night mode. This would
require an ATI circuit card connected to a Night switch.
6. CALL FORWARDING - ALL CALLS [C-5] / BUSY LINE [C-2]: When a Direct Inward Dialing (DID)
call terminates to a station setting CALL FORWARDING - ALL CALLS [C-5] or BUSY LINE [C-2] to
the Attendant, the call can be answered using the TAS feature.
7. CLASS OF SERVICE-INDIVIDUAL [C-15]: Stations must be allowed access to TAS via Service Feature
Class. The station Route Restriction Class will either allow or deny connection to incoming C.O. calls via
TAS. 
8. DAY/NIGHT CLASS OF SERVICE [D-15]: A CLASS OF SERVICE-INDIVIDUAL [C-15] change that
occurs when the system goes into Night mode may allow a station to answer incoming trunk calls that are
restricted to that station in Day mode. 
9. HOUSE PHONE [H-2], INDIVIDUAL ATTENDANT ACCESS [I-6], STATION-TO-STATION
CALLING-OPERATOR ASSISTANCE [S-12], and ATTENDANT NIGHT TRANSFER [A-19]: These
calls will not be directed to TAS when the system is in Night mode.
10. CONSULTATION HOLD [C-17]: TAS cannot be accessed via CONSULTATION HOLD. 
11. TRUNK ANSWER ANY STATION will not default if other provisions are not made to answer incoming
calls when the system is in Night mode. See the ACFR command. 
12. The type of Attendant Console system used determines how the system will enter into the Night mode.
See System Data 2, Index 2, Bits 2 & 3. 
13. A user receives a reorder tone after dialing the TAS access code if one or more of the following applies:
a.) Station line is inward restricted.
b.) Station line is fully restricted.
c.) Station is restricted from the TAS access code.
d.) Station has a party on Hold.
e.) Another station has answered the TAS call and no other calls are in the TAS queue.
14. Incoming calls remain in the TAS queue until answered from a station or until abandoned by the far end.

Tenant Service T-12
T-12 Tenant Service
General Description
This feature provides for more than one organization (tenant) to share the same PBX. Through system programming,
each organization may be restricted to its own Central Office trunks, ATTENDANT CONSOLEs [A-3], and
extension links. In addition, incoming calls are directed to the specific organization (tenant). 
Operating Procedure
No manual operation is required.
Service Conditions 
1. An Attendant Console is normally provided for each tenant. However, when required, a single common
console may be shared by two or more tenants.
2. Inter-office calling between tenants may or may not be restricted, depending on System Data.
3. Different tenants may share a common group of trunks, where required. 
4. When a tenant station dials “0” (Operator Call Code), it will be connected to that tenant’s console.
5. Different tenants cannot use the same numbering plan.
6. The same telephone numbers cannot be assigned among different Tenants (for example, stations
numbered 2XXX can be associated with only one Tenant).
7. STATION-TO-STATION [S-11], CALL TRANSFER [C-11] THREE-WAY CALLING [T-2], TAS [T-
8] and CALL FORWARDING [C-2, 3, 5] calls between Tenants can be restricted or allowed.
8. SMDR [S-10] includes Tenant identification.
9. The same access code can be assigned among Tenants for service features (for example, CALL HOLD
[C-6], CALL BACK [C-1], CALL PICKUP - GROUP [C-7], CALL FORWARDING - ALL CALLS -
D
term [C-5D], SPEED CALLING [S-3], TAS [T-8], etc.).
10. The NEAX2400 IMX can provide TENANT SERVICE [T-12] to a maximum of 63 tenants.
11. Tenant numbers should be allocated on a network basis for the FCCS network.
Interactions 
1. To provide TENANT SERVICE, features need not be separated. Whenever possible, keep features
common to use data memory as economically as possible. When commands are separated, they must be
programmed for each tenant accommodated in System Data 2.
2. FORCED ACCOUNT CODES [F-7] and AUTHORIZATION CODES [A-20] do not require separate
tenant service for AMND, System Data 1, Index 93, Bit 6.
3. Each tenant may have its own Attendant Console(s), unless that number exceeds system capacity; for
example, five tenants in a two-PIM configuration. The number of consoles per tenant is not limited by
programming but is limited by the system configuration. 
4. Different tenants may or may not share the same CO trunks. Termination of a trunk is a function of the
ARSC command. DID trunks can be assigned to any tenant. However, the Listed Directory Number, as
assigned in the ALDN command, determines where the call terminates. If the incoming LDN digits are
assigned against Tenant 2, the call terminates to the Tenant 2 Attendant Console, even if the digits come
on a Tenant 1 trunk.

Interactions (cont’d)
5. CALL FORWARDING [C-2, 3, 5]: When a station call forwards to the Attendant Console, the call will
go to the originating station’s Attendant Console, as assigned via the Tenant parameter of the ATRK
command.
6. CLASS OF SERVICE-INDIVIDUAL [C-15]: Refer to the programming section. This feature affects the
construction of all classes of service.
