Function
RADEASTFP
Input
AB18
Remote Alarm Port East Frame Pulse
(RADEASTFP).
The remote serial alarm port east
frame pulse is used to locate the alarm bits of the
individual tributaries in the east remote serial alarm
port. RADEASTFP is set high to mark the first BIP-2
error bit of tributary TU #1 in TUG2 #1 of TUG3 #1
carried in RADEAST. RADEASTFP must be set high
to mark every occurrence of this bit. TEMUX will not
flywheel on RADEASTFP in order to accommodate a
variety of RADEASTCK frequencies.
RADEASTFP is sampled on the rising edge of
RADEASTCK.
RADEAST
Input
W18
Remote Alarm Port Data East (RADEAST).
The
remote serial alarm port east carries the tributary path
BIP-2 error count, RDI status, and RFI status in the
east remote serial alarm port. The first BIP-2 error bit
of tributary TU #1 in TUG2 #1 of TUG3 #1 on
RADEAST is marked by a high level on RADEASTFP.
The status carried on RADEAST 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].
RADEAST is sampled on the rising edge of
RADEASTCK.
RADWESTCK
Input
AA18
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.
