Authorization Code - Tie Line Incoming Routes A-29
A-29 Authorization Code - Tie Line Incoming Routes
General Description
This service feature offers an outside party the ability to enter an AUTHORIZATION CODE [A- 20] through an
incoming TIE Line trunk.
Operating Procedure
When the incoming route is restricted or when an AUTHORIZATION CODE [A-20] is always required
1. The called number, office code, and terminal number are received by the TIE Line trunk.
2. The outside calling party hears a special dial tone.
3. Dial the AUTHORIZATION CODE [A-20].
a.) The connection is established when the AUTHORIZATION CODE [A-20] is valid.
b.) Busy tone is sent to the calling party when the AUTHORIZATION CODE [A-20] is invalid.
Service Conditions
1. The outside calling party must be able to generate DTMF signals to the NEAX2400 IPX when entering
AUTHORIZATION CODE [A-20].
2. An AUTHORIZATION CODE [A-20] can be used for incoming calls to a uniform station or for LEAST-
COST ROUTING [L-5] tandem connections.
3. CALL WAITING - TERMINATING [C-12] is available when the called station is busy, after the
AUTHORIZATION CODE [A-20] is entered and validated.
4. INTER-OFFICE OFF-HOOK QUEUING [I-11] is available if the called route is busy, after the
AUTHORIZATION CODE is entered and validated.
5. Through programming, the system defines the AUTHORIZATION CODE [A-20] to be required for all
TIE Line incoming calls or when a restriction is encountered. This is assigned on a per-tenant basis.
Note: There are two methods of AUTHORIZATION CODE assignment - Full Implementation and the Checksum.
In the Full Implementation method, the whole AUTHORIZATION CODE is assigned in the AATC
command, and System Data 1, Indexes 12, 13,& 14 are assigned 00H. In the Checksum method, partial
assignment for each AUTHORIZATION CODE is assigned in the AATC command. The last one or two
digits (programmable option) are determined by the system according to the data assignments in ASYD,
System Data 1, Indexes 12, 13, and 14.
Interactions
1. If FORCED ACCOUNT CODES [F-7] are used, AUTHORIZATION CODES-TIE LINE INCOMING
ROUTES are not allowed within the same tenant.
2. AUTHORIZATION CODES-TIE LINE INCOMING ROUTES may be used in conjunction with
ACCOUNT CODES [A-18].
3. When assigning an AUTHORIZATION CODE Restriction of 1 in AATC, the RSC must be constructed
in ARSC.
4. AUTHORIZATION CODEs can be unrestricted or assigned one of 15 Route Restriction Classes.
5. There are no restrictions regarding the first digit of AUTHORIZATION CODEs, except what is
programmed in AMND. Tenant 0 does not conflict with the PBX numbering plan.
Note: The access code to the feature AUTHORIZATION CODE - TIE LINE INCOMING ROUTES must be
assigned within the PBX numbering plan.
