SATURN USER NETWORK INTERFACE (155-QUAD)

• Captures and debounces the synchronization status (S1) byte in a readable

register.

• Filters and captures the automatic protection switch channel (K1, K2) bytes in

readable registers and detects APS byte failure.

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

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

end block errors (FEBE).

• 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 (PRDI) and path extended remote defect indicator (PERDI).

• Interprets the received payload pointer (H1, H2) and extracts the STS-3c

(STM-1) synchronous payload envelope and path overhead.

• Provides individual divide by 8 recovered clocks (19.44 MHz) for each

channel.

• Provides individual 8KHz receive frame pulses for each channel.

1.3 The Receive ATM Processor

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

envelope 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).

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

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

1.4 The SONET Transmitter

• Synthesizes the 155.52 MHz transmit clock from a 19.44 MHz reference.
