ABSTRACT:
An improved telephone station set for use with a switching system which senses flashing is disclosed. A separate flash key is included on the set. Depression of the flash key causes decoupling of the set for a predetermined time which corresponds to the flash window. Depression of the hook switch, assures decoupling of the set for a sufficiently long period of time so that a hang-up is detected even if the hook switch is immediately released.
