Operator Calls Over Network
Use this address to block incoming Network Trunk Group
caller from being able to access a trunk and dialing "0",
"00", "10XXX0", or "101XXXX0" to reach an operator.
This prevents a user from being able to make a restricted
phone call by asking the operator to place the call for him
FF1 8# 4# 8# 3# (NWG)# 23# (0-3)#
0=Deny "0/00-only", "10XXX0-only", and
"101XXXX0"-only calls, but allow "0+NXX" calls if
permitted by TRS tables
1=Allow "0/00-only", "10XXX0-only", and "101XXXX0-
only" calls, and also allow "0+NXX" calls if permitted by
TRS tables
2=Deny "0/00-only", "10XXX0-only", and "101XXXX0-
only" calls, but allow "0+NXX" calls regardless of TRS
tables
3=Allow "0/00-only", "10XXX0-only", and "101XXXX0-
only" calls,and also allow "0+NXX" calls regardless of
TRS tables
The Operator Access address still applies only to DBS sys-
tems using the new (1995) NANP dialing plan (FF7 1# 17#
1#), and to TRS types 2-6 (TRS types 0 and 1 do not allow
outbound dialing; TRS type 7 allows all dialing).
If "0/00-only" calls are denied (settings 0 or 2), the system
will wait 6 seconds before automatically disconnecting the
call. However, if the user dials additional digits within 6
seconds, the DBS will check other TRS switches to deter-
mine whether to allow or deny the call.
For all settings (0-3), the system will check the CIC Format
switch (FF7 1# 21#...) if an interchange carrier code is
dialed.
For all settings (0-3), the system will check the international
calls switches (FF7 1# 1# and FF7 1# 19#) if "01" or "011"
is dialed.
For settings 0 and 1, the system will additionally check TRS
tables for the TRS type assigned to the trunk and the FF7
settings for that TRS type (such as allowed/denied area
codes, office codes, and 7-digit dialing).
