1.8 Toll Restriction (TRS)/Call Barring (Barring) Features
Feature Guide 127
• ARS
If ARS is applied to a dialled number, TRS/Barring will check the user-dialled number (not the modified
number by ARS). In this case, a Host PBX Access code and/or a Special Carrier Access code will not
be checked.
• Dialling Digit Restriction during Conversation
The dialling of digits can be restricted while engaged on a received trunk call. If the number of dialled
digits exceeds the preprogrammed limitation, the line will be disconnected.
→ 3.13.5 [7-5] Miscellaneous—Dial Digits Limitation After Answering—Dial Digits
• 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.
→ 3.13.5 [7-5] Miscellaneous—Mode when Dial Time-out before TRS Check
– 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.
• A TRS/Barring level can be changed by some features. The priority of features, when multiple features
are used, is as follows:
1) Dial Tone Transfer (→ 1.8.4 Dial Tone Transfer)
2) Budget Management (→ 1.8.2 Budget Management)
3) TRS/Barring Override by System Speed Dialling
4) Walking COS/Verification Code Entry
(→ 1.8.5 Walking COS, 1.8.6 Verification Code Entry)
5) Extension Dial Lock
