SATURN USER NETWORK INTERFACE PLUS

• Extracts ATM cells from the received STS-3c/1 (STM-1) synchronous payload

envelope using ATM cell delineation and provides optional ATM cell payload

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

and idle/unassigned cell filtering.

• Provides a generic 16 bit or 8 bit wide datapath interface to read extracted

cells from an internal four cell FIFO buffer.

• Extracts all transport overhead bytes and serializes them at 5.184 Mbit/s for

optional external processing.

• Extracts the section user channel (F1) and the orderwire channels (E1, E2)

and serializes them into three independent 64 kbit/s streams for optional

external processing.

• Extracts the data communication channels (D1-D3, D4-D12) and serializes

them at 192 kbit/s (D1-D3) and 576 kbit/s (D4-D12) for optional external

processing.

• Extracts all path overhead bytes and serializes them at 576 kbit/s for optional

external processing.

• Extracts the 16 or 64 byte section trace (J0) sequence and the 16 or 64 byte

path trace (J1) sequence into internal register banks.

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

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

pointer (LOP), path alarm indication signal (PAIS), path remote defect

indication signal (PRDI) and loss of cell delineation (LCD).

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

line far end block errors (M0 or M1), received path BIP-8 (B3) errors and path

far end block errors (G1) for performance monitoring purposes.

• Counts received cells written into the receive FIFO, received HCS errored

cells that are discarded, and received HCS errored cells that are corrected

and passed through the receive FIFO.

• Extracts and serializes the GFC field from all received cells (including

idle/unassigned cells) for external processing.
