Loss of PRBS Pattern Lock Indicator:
This READ-ONLY bit-field indicates whether or not the
PRBS Receiver (within the Receive Section of Channel 0)
is declaring PRBS Lock within the incoming PRBS pattern.
If the PRBS Receiver detects a very large number of bit-
errors within its incoming data-stream, then it will declare
the Loss of PRBS Lock Condition.
Conversely, if the PRBS Receiver were to detect its pre-
determined PRBS pattern with the incoming DS3, E3 or
STS-1 data-stream, (with little or no bit errors) then the
PRBS Receiver will clear the Loss of PRBS Lock condi-
tion.
0 - Indicates that the PRBS Receiver is currently declaring
the PRBS Lock condition within the incoming DS3, E3 or
STS-1 data-stream.
1 - Indicates that the PRBS Receiver is currently declaring
the Loss of PRBS Lock condition within the incoming DS3,
E3 or STs-1 data-stream.
N
OTE
:
This register bit is only valid if all of the following are
true.
a.
The PRBS Generator block (within the Transmit
Section of the Chip is enabled).
b.
The PRBS Receiver is enabled.
c.
The PRBS Pattern (that is generated by the PRBS
Generator) is somehow looped back into the
Receive Path (via the Line-Side) and in-turn routed
to the receive input of the PRBS Receiver.
