TGAR and TARG

If a route (RDB) is set to type (TKTP) = TIE, then the access restrictions are controlled by TGAR (Trunk Group Access Restrictions) and TARG (Trunk Access Restriction Group). A TARG/TGAR match denies ACOD access (dialing the access code). TGAR is also checked if LD 86 ESN, TGAR=YES (not default).

The rule is: when TARG and TGAR match, the set is denied access to the route. A set with a TGAR of 0 (zero) has no access restrictions.

Eg: When a set with a TGAR of "1" dials the route access code of a route with a TARG of "1", the call is blocked.

• TGAR is assigned to a phone. Each phone has one TGAR entry, 0=unrestricted (PRT in LD 20).
• TARG is assigned to the trunk route. Each route can have multiple TARG entries (PRT in LD 21).

Example:

Set↓ RDB→	TARG: 1	TARG: 1 2 3	TARG: 1 3	TARG: 3	TARG: 4
TGAR: 0	✅	✅	✅	✅	✅
TGAR: 1	❌	❌	❌	✅	✅
TGAR: 2	✅	❌	✅	✅	✅
TGAR: 3	✅	❌	❌	❌	✅
TGAR: 4	✅	✅	✅	✅	❌
