Preliminary Data Sheet
The line interface is not transmitting. There is no signal detected on the S interface,
and no activation command is received.
As a result of an INFO 1 detected on the S line or an AR command, the line interface
begins transmitting INFO 2 and waits for reception of INFO 3. The timer to supervise
reception of INFO 3 is to be implemented in software. In case of an ARL command,
loop 2 is closed.
Normal state where INFO 4 is transmitted to the S interface. The line interface
remains in this state as long as neither a deactivation nor a test mode is requested,
and the receiver does not loose synchronism. When receiver synchronism is lost,
INFO 2 is sent automatically. After reception of INFO 3, the transmitter continues
sending INFO 4.
This state is reached when the line interface has lost synchronism in the state G3
activated.
This state is triggered by a deactivation request DR. It is an unstable state: status DI
(state “G4 wait for DR”) is issued by the DELIC when either INFO 0 is received, or an
internal timer of 32 ms expires.
Final state after a deactivation request. The line interface remains in this state until a
response to DI (in other words DC) is issued.
Single alternating pulses are sent on the S interface (2 kHz repetition rate).
Continuous alternating pulses are sent on the S interface (96 kHz).
