SATURN USER NETWORK INTERFACE (155-QUAD)

Provides a differential TTL serial interface (can be adapted to PECL levels) at 155.52 Mbit/s.

Provides a single transmit frame pulse input across the four channels to align the transport frames to a system reference.

Provides a single transmit byte clock (divide by eight of the synthesized line rate clock) to provide a timing reference for the transmit outputs.

Optionally inserts register programmable APS (K1, K2) and synchronization status (S1) bytes.

Optionally inserts path alarm indication signal (PAIS), path remote defect indication (PRDI), line alarm indication signal (LAIS) and line remote defect indication (LRDI).

Inserts path BIP-8 codes (B3), path far end block error (G1) indications, line BIP-24 codes (B2), line far end block error (M1) indications, and section BIP-8 codes (B1) to allow performance monitoring at the far end.

Scrambles the transmitted STS-3c (STM-1) stream and inserts the framing bytes (A1, A2).

Inserts ATM cells into the transmitted STS-3c (STM-1) synchronous payload envelope.

1.5The Transmit ATM Processor

Provides idle/unassigned cell insertion.

Provides HCS generation/insertion, and ATM cell payload scrambling.

Counts number of transmitted and idle cells.

Provides a synchronous 8-bit wide, four cell FIFO buffer.
