ignore previous post,,,,try this TGAR/TARG barring can be used to make extensions select a particular route.
Starting with the extension you assign it a TGAR value. It is only a number between 0-31 and it only has any significance if you use the Trunk Busy keys on the console for routes 0-19.
An extension with a TGAR from 0 to 7 accessing the route that has been busied out will be automatically intercepted to the attendant. Station users with a TGAR of 8 to 31 will not be affected and can dial out in the normal manner. See the Feature and Services guide, "Attendant Trunk Group Busy Indication" and "Access Restrictions" for TGAR/TARG barring.
So you would assign a TGAR value to extensions 5600-5679, say 5 and for 5680-5699 say 6.
Then in the Route Data Block (RDB) for route 43 you would add TGAR 6 and route 44 TGAR 5.
If The TGAR matches a TARG entry the call is barred. If the TGAR doesn't appear in the TARG prompt the call will be allowed. You only have one TGAR value on each extension but TARG on the route can have several entries.
Use overlay LD 21 for printing the routes. LD 16 for to amend the RDB.
