In the state G3 (Activated) the B1, B2 and D bits are transferred transparently from the
S/T to the IOM
IOM
2.4.4
C/I commands ARL and AIL close the analog loop as close to the S-interface as possible.
ETSI refers to this loop under ’loopback 2’. ETSI requires, that B1, B2 and D channels
have the same propagation delay when being looped back.
The D-channel Echo bit is set to bin. 0 during an analog loopback (i.e. loopback 2). The
loop is transparent.
Note: After C/I-code AIL has been recognized by the S-transceiver, zeros are looped

The state diagram notation is given in
The information contained in the state diagrams are:
– state name
– Signal received from the line interface (INFO)
– Signal transmitted to the line interface (INFO)
– C/I code received (commands)
– C/I code transmitted (indications)
– transition criteria
The transition criteria are grouped into:
– C/I commands
– Signals received from the line interface (INFOs)
– Reset
