2.
Originating side releases the call.
The originating side sends a clear-forward signal 10. When the terminating side recognizes the
clear-forward signal, it sends a backward signal 10 (release guard signal or clear-forward
acknowledgement signal). After the originating side recognizes the backward signal 10, it
releases the circuit.

Terminating side releases the call.
The terminating side sends a clear-back signal 11. After the originating side receives the
clear-back signal, it sends a clear-forward signal 10. After the terminating side recognizes the
forward signal 10 sent by the originating side, it sends a backward signal 10. After the
originating side recognizes the backward signal 10, it releases the circuit.

Line released by forced release signal.
When the terminating side supports metering signals, the system might send a forced release
signal 00 instead of a clear-back signal 11 to release the line. This is to avoid collision between
the clear-back signal sent by the called party and the metering signal.
5.
Blocking in idle state or during conversation.
After the originating side receives a blocking signal 11 from the terminating side when the circuit
is idle or during conversation, it sends a forward signal 10. At this time, the circuit is blocked.
When the terminating side unblocks the circuit, it sends a backward signal 10 in the
corresponding line to indicate that the line is idle. The originating side should maintain the
forward signal 10 and unblock the local-end circuit for next call.
6.
Troubleshooting in idle state.
If the terminating side receives a forward signal 11 from the originating side to indicate a device
fault when the circuit is idle, the terminating side sends a backward signal 11. Then, the circuit is
in faulty state. When the device recovers, the originating side sends the forward signal 10, and
the terminating side responds with the signal 10. At this time the circuit regains normal state.
