SATURN USER NETWORK INTERFACE (622-POS)

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA INC., AND ITS CUSTOMERS’ INTERNAL USE

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

indication signal (AIS-L), line remote defect indication (RDI-L), loss of pointer

(LOP), path alarm indication signal (AIS-P), path remote defect indication (RDI-

P), path extended remote defect indicator (extended RDI-P).

• Counts received section BIP-8 (B1) errors, received line BIP-96 (B2) errors, line

remote error indicates (REI-L), received path BIP-8 (B3) errors and path remote

error indications (REI-P) for performance monitoring purposes.

The Receive ATM Processor

• Extracts ATM cells from the received STS-12c/STM-4-4c or STS-3c/STM-1

payload using ATM cell delineation.

• Provides ATM cell payload de-scrambling.

• Performs header check sequence (HCS) error detection and correction, and

idle/unassigned cell filtering.

• Detects out of cell Delineation (OCD) and loss of cell delineation (LCD) alarms.

• Counts number of received cells, idle cells, errored cells and dropped cells.

• Provides a UTOPIA Level 2 compliant 16-bit wide datapath interface (clocked up

to 50 MHz) with parity support to read extracted cells from an internal four-cell

FIFO buffer.

• Provides a UTOPIA Level 3 compatible 8-bit wide datapath interface (clocked up

to 100 MHz) with parity support to read extracted cells from an internal four-cell

FIFO buffer.

1.4

The Receive POS Processor

• Supports packet based link layer protocols using byte synchronous HDLC

framing like PPP, HDLC and Frame Relay.

• Performs self-synchronous POS data de-scrambling on the received STS-

12c/STM-4-4c or STS-3c/STM-1 payload using the x

43+1 polynomial.

• Performs flag sequence detection and terminates the received POS frames.

• Performs frame check sequence (FCS) validation for CRC-CCITT and CRC-32

polynomials.
