Feature description
The China – Supervised Analog Lines feature provides two types of call
supervision signaling capabilities: battery reversal answer/disconnect
supervision and hook flash disconnect supervision. These forms of
supervision are provided to terminal devices connected to analog ports in the
Meridian 1 system.
Battery Reversal Supervision
Battery reversal answer and disconnect supervision signaling is used for calls
originating from the terminal device. It provides both far-end (the called
party) answer supervision and far-end disconnect supervision signals to the
terminal device. It does not apply to incoming calls terminating at the
terminal device.
