Remote Alarm Port West Frame Pulse
(RADWESTFP). The remote serial alarm port west
frame pulse is used to locate the alarm bits of the
individual tributaries in the west remote serial alarm
port. RADWESTFP is set high to mark the first BIP-2
error bit of tributary TU #1 in TUG2 #1 of TUG3 #1
carried in RADWEST. RADWESTFP must be set high
to mark every occurrence of this bit. TEMAP will not
flywheel on RADWESTFP in order to accommodate a
variety of RADWESTCK frequencies.
RADWESTFP is sampled on the rising edge of
RADWESTCK.
RADWEST
Remote Alarm Port Data West (RADWEST). The
remote serial alarm port west carries the tributary path
BIP-2 error count, RDI status, and RFI status in the
west remote serial alarm port. The first BIP-2 error bit
of tributary TU #1 in TUG2 #1 of TUG3 #1 on
RADWEST is marked by a high level on RADWESTFP.
The status carried on RADWEST is software
selectable to be reported on the RDI, RFI and REI
alarms and is selectable to be associated with any
tributary on the outgoing data stream LADATA[7:0].
RADWESTFP is sampled on the rising edge of
RADWESTCK.
CLK52M
52MHz Clock Reference (CLK52M). The 52Mhz clock
reference is used to generate a gapped DS3 clock
when demapping a DS3 from the SONET stream and
also to generate a gapped DS3 clock when receiving a
DS3 from the SBI bus interface. This clock has two
nominal values.
The first is a nominal 51.84MHz 50% duty cycle clock.
The second is a nominal 44.928MHz 50% duty cycle
clock.
When this clock is not used this input must be
connected to ground.
