1.9.1 Toll Restriction (TRS)/Call Barring (Barring)
•
It is possible to select through system programming whether the trunk is disconnected when the Inter-digit
time expires without the TRS/Barring check being completed.
–
If no disconnection is chosen, the TRS/Barring check will also be performed after the Inter-digit time
expires.
–
If disconnection is chosen, the line will be disconnected when the trunk Inter-digit time expires. This
also prevents EFA from being used.
This setting applies to all trunks.
•
