Activation Procedure from the TE
In idle “F3” status, the TE send the
INFO1 signal to the NT and changes to
“F4” status. The NT then changes to
“G2” status and sends INFO2 signal to
the TE.
The TE changes to “F5” status and
stops sending signals to synchronize
itself to the signal from the NT.
After the TE has synchronized to the
signal, it sends INFO3 signal to the NT
and changes to the “F6” status.
The NT then changes to “G3” status and
sends INFO4 signal back to the TE to
inform that a physical link has been
established.
The timers T1, T2 and T3 are used to
reset the TE or NT if a correct response
has not received before the timers
expire.
