SATURN USER NETWORK INTERFACE

• Counts received section BIP-8 (B1) errors, received line BIP-8/24 (B2) errors, line
far end block errors (FEBE), received path BIP-8 (B3) errors and path far end
block errors (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 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).
• Synthesizes the 155.52 MHz, 51.84 MHz transmit clock from a one-eighth
frequency reference.
• Provides a serial interface at 155.52 or 51.84 Mbit/s
• Inserts path alarm indication signal (AIS), path remote defect indication (RDI), line
alarm indication signal (AIS) and line RDI.
• Inserts path BIP-8 codes (B3), path far end block error (FEBE) indications, line
BIP-8/24 codes (B2), line far end block error (FEBE) indications, section BIP-8
codes (B1) to allow performance monitoring at the far end.
• Allows forced insertion of all zeros data (after scrambling) or corruption of framing
byte or section, line, or path BIP-8 codes for diagnostic purposes.
