TRS—Extension Lock Class

The class of service (COS) of extensions locked by the Extension Lock or Remote Extension Lock
feature can be assigned (

[312] TRS—Extension Lock Class) so that even a locked extension can

make outside (CO) line calls. The higher COS number will take precedence. If, for example, COS 3 is
assigned to an extension (

[601-603] TRS-COS—Day/Night/Lunch) and the COS of locked

extensions is assigned as "4", when the extension is locked, the PBX allows the extension user to make
outside (CO) line calls using COS 4.

•

Extension Lock—CANCEL ALL

The operator or manager can cancel this feature for all extensions simultaneously.

•

This feature also functions as Call Log Display Lock, Incoming (

1.1.18 Call Log, Incoming).

The Incoming Call Log for the common area can only be locked or unlocked by the operator or manager
(Call Log Display Lock, Incoming in the Common Area).

•

This feature will not block Emergency Calls (

1.1.49 Emergency Call).
