1.5 The SONET Transmitter

PM5352 S/UNI STAR

SATURN USER NETWORK INTERFACE 155 (STAR)

• Synthesizes the 155.52 MHz transmit clock from a 19.44 MHz

reference.

• Provides a differential TTL serial interface (can be adapted to PECL

levels) at 155.52 Mbit/s with both line rate data (TXD+/-) and clock

(TXC+/-).

• Provides a transmit frame pulse input to align the transport frames to a

system reference.

• Provides a transmit byte clock (divide by eight of the synthesized line

rate clock) to provide a timing reference for the transmit outputs.

• Optionally inserts register programmable APS (K1, K2) and

synchronization status (S1) bytes.

• Optionally inserts path alarm indication signal (PAIS), path remote

defect indication (PRDI), line alarm indication signal (LAIS) and line

remote defect indication (LRDI).

• Inserts path BIP-8 codes (B3), path far end block error (G1)

indications, line BIP-24 codes (B2), line far end block error (M1)

indications, and section BIP-8 codes (B1) to allow performance

monitoring at the far end.

• Optionally inserts the section and line data communication channels

(D1-D3 or D4-12) via a 192 kbit/s (D1-D3) and 576 kbit/s (D4-D12)

serial stream.

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

the 16 or 64 byte path trace (J1) sequence from internal register

banks.

• Scrambles the transmitted STS-3c (STM-1) stream and inserts the

framing bytes (A1,A2).

• Inserts ATM cells or POS frames into the transmitted STS-3c (STM-1)

synchronous payload envelope.

1.6 The Transmit ATM Processor

• Provides idle/unassigned cell insertion.
