Functional Description
Data Sheet

G1 Deactivated
The S-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. 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 S-transceiver is waiting for an AR command, which
normally indicates that the transmission line upstream 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 S-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 transmission line, the S-transceiver transmits INFO 2.
G4 Pending Deactivation
This state is triggered by a deactivation request DR, and is an unstable state. Indication
DI (state
“
G4 wait for DR
”
) is issued by the transceiver when:
either INFO0 is received for a duration of 16 ms
or an internal timer of 32 ms expires.
