Facility restriction levels and traveling class marks
Facility Restriction Levels (FRL) and Travelling Class Marks (TCM) allow certain calls to specific users,
and deny the same calls to other users. For example, you can give certain users access to CO trunks to
other corporate locations, and you can restrict other users to less expensive, private-network lines.
Detailed Description
FRL
Communication Manager compares the FRL of the outgoing phone to the FRL of either the terminating
trunk group or, for AAR and ARS, the routing preference specified on the Routing Pattern Table. If the
FRL of the originator is equal to or greater than the terminating or route pattern FRL, the call continues.
Otherwise, the call is blocked.
TCM
If an intertandem tie-trunk group is used for a call, then a TCM is outpulsed as the last digit. If the
intertandem tie-trunk FRL is equal to or greater than the terminating FRL, the call continues. If the
originating FRL is less than the terminating FRL, the TCM is compared with the tie-trunk's FRL. If the
TCM is greater than or equal to the FRL, the call continues.
Call-originating facilities
Any of the following can originate an AAR or ARS call. Each is assigned an FRL via an associated COR.
•
attendant
•
data terminal capable of keyboard dialing
•
incoming tie-trunk group from a subtending location
•
incoming intertandem tie-trunk group (at a tandem server or switch)
•
incoming access tie-trunk group (links a remote main server/switch to a tandem server/switch)
•
phone
•
remote access user
Phones and all incoming tie-trunk groups use the FRL of their COR. On attendant-extended calls, the
attendant-group FRL is used. If Individual Attendant Access assigned, the individual attendant's COR
FRL is used. Data terminals use the FRL of the COR assigned to the associated data module.
A remote access call uses the FRL of the COR assigned to the dialed barrier code. If a barrier code is not
required on remote access calls, there is no FRL.
