SecurityAlert:
It is recommended that Outward Restrict be set at all times, otherwise toll
fraud can occur. If the switch is part of a network and restrictions need to be
changed from Outward Restricted, barrier codes should be required.
Transfer the information from Form 2c, System Numbering: Line/
Trunk Jacks to Form 3a:
1. Write the logical ID and line/trunk number in the applicable
columns.
2. Check either the DID or Tie Trunk column or the Non-Tie
Trunk column.
3. Complete the Line/Trunk Type and Description column.
Include the different calling areas of WATS trunks and
different destinations for FX trunks. If a network trunk, write
Network.
For each line/trunk, check the Dedicated column (to indicate that it is
always used for remote access) or the Shared column (to indicate
that it is used for remote access when the system is in Night Service
operation). Do not check either column for network trunks.
Under the Network Calls heading, check one of the boxes using the
following information:
— If the switch is not part of a private network, check None.
— If the switch is part of a private network, and tandem calls will
pass through this system, check Tandem.
— If the switch is part of a private network, and network calls will
be allowed to access PSTN trunks, check ARS.
NOTE:
If Tandem or ARS is selected under Network Calls, the Restriction
should be set to Unrestricted. For additional information on private
networks, see Network Reference . Contact the Network Engineering
Group for assistance.
For Restriction, check one of the following three boxes:
Unrestricted, Outward Restrict (to keep the factory setting), or Toll
Restrict.
