Y10 Remote Alarm Port West Frame Pulse
AA10 Remote Alarm Port Data West (RADWEST). The
Function
Remote Alarm Port West Clock (RADWESTCK). The
remote serial alarm port west clock provides timing for
the west remote serial alarm port. It is nominally a
9.72 MHz clock, but can range from 1.344 MHz to
10 MHz.
Inputs RADWESTFP and RADWEST are sampled on
the rising edge of RADWESTCK.
(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-84 will
not flywheel on RADWESTFP in order to
accommodate a variety of RADWESTCK frequencies.
RADWESTFP is sampled on the rising edge of
RADWESTCK.
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 by 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.
