The Rx APS Port interface receives the synchronous payload data from the mate PHAST-
12P. It will also monitor the in-band forwarded of RxAPS, TxAPS, Status and Request
indications. The TxAPS will be forwarded to the TOH Generator. The latter will have an option
to insert the transmitted K1/K2 APS autonomously from the TxAPS on the Rx APS Port or
from software controlled registers.
The functionality of the APS Interfaces described in
presence of the AU Pointer Tracker and the STM-4 like APS frame makes the APS port can
be used as a STM-4 SONET Lite Port. Important limitation to know about this: the incoming
B2 bytes are NOT processed by the APS Monitor. Remark also the APS port has LVDS I/Os
while the Line Ports has LVPECL I/Os
• RxAPS: forwarded from the receive line interface, or optionally under software control
• TxAPS: under software (APS finite state machine) control
• Status: forwarded from the receive line interface, or optionally under software control
• Request: under software (APS finite state machine) control
