SATURN USER NETWORK INTERFACE (622-MAX)
•
•
•
•
Provides a differential PECL bit-serial interface at 622.08 Mbit/s.
Inserts a register programmable path signal label (C2).
Generates the transmit payload pointer (H1, H2) and inserts the path overhead.
Scrambles the transmitted STS-12c/STM-4-4c or STS-3c/STM-1 stream and inserts the framing bytes
(A1, A2).
•
•
•
Optionally inserts register programmable APS bytes.
Provides a byte-serial transmit path data stream allowing two devices to implement 1+1 APS.
Inserts path BIP-8 codes (B3), path remote error indications (REI-P), line BIP-96 codes (B2), line
remote error indications (REI-L), and section BIP-8 codes (B1) to allow performance monitoring at the
far end.
•
Allows forced insertion of all-zeros data (after scrambling) and the corruption of the section, line, or
path BIP-8 codes for diagnostic purposes.
•
Inserts ATM cells into the transmitted STS-12c/STM-4-4c or STS-3c/STM-1 payload.
1.5
The Transmit ATM Processor
•
•
•
•
Provides idle/unassigned cell insertion.
Provides HCS generation/insertion, and ATM cell payload scrambling.
Counts number of transmitted and idle cells.
Provides a UTOPIA Level 2 compliant 16-bit wide datapath interface (clocked up to 50 MHz) with
parity support for writing cells into an internal four-cell FIFO.
•
Provides a UTOPIA Level 3 compatible 8-bit wide datapath interface (clocked up to 100 MHz) with
parity support for writing cells into an internal four-cell FIFO.
