Re: questions on PCS synchronization : state diagram


Hi Birdy,

I have a question regarding this state diagram.  It appears that
the HIBER state relative to the LOCK state really has no
purpose.  The same conditions ("unlock") would bring the
state machine to SLIP. My question is - is the purpose of
the HIBER state is to use it as a qualifier for going into
the LOCK state.  In other words, if we currently in UNLOCK,
and if we start seeing a high BER, them we must first see
a low BER before  looking at the sync bits.
=============================================
Netscape munged up my state diagram. I am
resending it.Hope it comes ok  this time.



               hiber
-------    ------------>   -------
| LOCK  | /               | HIBER |
-------  < _____________ / -------
    ^ \       ~hiber         |
    |  \                     |
    |   \ ______             | unlock
    |     unlock\            |
    |lock        \           |
    |      unlock \-->       V
---------  --------->  --------
| UNLOCK |/           |  SLIP  |
--------- <---------   --------
     ^      slip_done
     |
     |
   Start
