Loss of Optical Carrier Input - Primary Receive STS-3/STM-1 PECL
Interface - TTL Input:
If the user is using an Optical Transceiver that contains an LOS (or Sig-
nal Detect) output that is of the CMOS/TTL format, then connect this
LOS output signal to this input pin of the XRT94L31.
Configure the LOSTTL input pin to be either an active-low or an active-
high signal, by pulling the LOSPECL input pin to the appropriate level as
described below.
If this input pin is pulled to the appropriate state such that LOS is TRUE,
then all of the following events will happen.
The Primary Receive STS-3 TOH Processor block will declare the
Loss of Optical Carrier condition.
The Primary Receive STS-3/STM-1 Line Interface block will declare
the LOS_Detect condition.
NOTE: If this input pin is pulled to the appropriate state such that LOS is
TRUE, this (by itself) will NOT cause the Primary Receive STS-3
TOH Processor block to declare the LOS defect condition.
