SATURN USER NETWORK INTERFACE

• Recovers the clock and data; frames to the recovered data stream;

descrambles the received data; interprets the received payload pointer (H1,

H2); and extracts the STS-3c or STS-1 synchronous payload envelope (VC4)

and path overhead.

• Extracts ATM cells from the synchronous payload envelope using ATM cell

delineation and provides optional ATM cell payload descrambling, header

check sequence (HCS) error detection and error correction, and

idle/unassigned cell filtering.

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

• Detects loss of signal (LOS), out of frame (OOF), loss of frame (LOF), line

alarm indication signal (LAIS), line remote defect indication (RDI), loss of

pointer (LOP), path alarm indication signal (PAIS), loss of cell delineation and

path remote defect indication (PRDI).

• Counts received section BIP-8 (B1) errors, received line BIP-8/24 (B2) errors,

line far end block errors (line FEBE), received path BIP-8 (B3) errors and path

far end block errors (path FEBE).

• Counts received HCS errored cells that are discarded, received HCS errored

cells that are corrected and passed on, and the total received cells passed

on.

The transmitter section:

• Provides a serial interface at 155.52 or 51.84 Mbit/s.

• Provides a serial interface at 155.52 or 51.84 Mbit/s. Generates data of the

correct amplitude and shape to directly interface with a signal transformer and

transmit over a UTP-5 cable.

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

• Provides idle/unassigned cell insertion, HCS generation/insertion, and ATM

cell payload scrambling; Inserts ATM cells into the transmitted STS-3c (STM-

1) or STS-1 synchronous payload envelope using H4 framing

• Generates the transmit payload pointer (H1, H2) and inserts the path

overhead; scrambles the transmitted STS-3c (STM-1) or STS-1 stream and

inserts framing bytes (A1, A2) and the identity byte (C1).
