Restriction by Class of Service
One method of barring calls is by applying one of seven alternatives in the extension's Class of Service.
The seven Class of Service types are:-
UNR - Unrestricted - The extension user can dial anywhere they want - literally without restriction.
FRE - Fully Restricted - No exchange line access. The extension user can make internal calls, can use privately wired (Tie) lines, however they can have calls using exchange lines transferred to them from another extension user.
FR1 - Fully Restricted 1 - Same as FRE, but calls using exchange lines cannot be transferred to them.
FR2 - Fully Restricted 2 - This restricts the extension to internal calls only.
SRE - Semi-restricted - Allowed outgoing external calls via the attendant console only. Can receive external incoming calls.
TLD - Toll Denied - Allowed outgoing calls to certain destinations only. The Meridian 1 monitors the digits that are dialled to determine if the call is to be allowed. This process is called New Flexible Code Restriction.
CTD - Conditional Toll Denied – Not currently used in the UK

For UK switches we (should!) always allow 112 and 999 emergency numbers for all NCOS/FCR. Good call as it never hurts to remind people!
