Function

RADWESTCK

Input

W9 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

Input

Y10 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-84 will

not flywheel on RADWESTFP in order to

accommodate a variety of RADWESTCK frequencies.

RADWESTFP is sampled on the rising edge of

RADWESTCK.

RADWEST

Input

AA10 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 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.
