3.5.3.2
G1 Deactivated
The transceiver is not transmitting. There is no signal detected on the S/T-interface, and
no activation command is received in the C/I channel. The clocks are deactivated if the
bit MODE1.CFS is set to 1. Activation is possible from the S/T interface and from the
IOM-2 interface.
G1 I0 Detected
An INFO 0 is detected on the S/T-interface, translated to an “Activation Request”
indication in the C/I channel. The transceiver is waiting for an AR command, which
normally indicates that the transmission line upstream (usually a two-wire U interface) is
synchronized.
G2 Pending Activation
As a result of the ARD command, an INFO 2 is sent on the S/T-interface. INFO 3 is not
yet received. In case of ARL command, loop 2 is closed.
G2 wait for AID
INFO 3 was received, INFO 2 continues to be transmitted while the transceiver waits for
a “switch-through” command AID from the device upstream.
G3 Activated
INFO 4 is sent on the S/T-interface as a result of the “switch through” command AID: the
B and D-channels are transparent. On the command AIL, loop 2 is closed.
G2 Lost Framing S/T
This state is reached when the transceiver has lost synchronism in the state G3
activated.
G3 Lost Framing U
On receiving an RSY command which usually indicates that synchronization has been
lost on the two-wire U interface, the transceiver transmits INFO 2.
