SATURN USER NETWORK INTERFACE PLUS

The transmitter section:

• Provides an internal four cell FIFO into which cells are written using a generic

16-bit or 8-bit wide datapath interface.

• Inserts the generic flow control (GFC) bits via a simple serial interface and

provides a transmit XOFF function to allow for local flow control.

• Counts transmit cells read from the transmit FIFO.

• Provides idle/unassigned cell insertion, HCS generation/insertion, and ATM

cell payload scrambling.

• Inserts ATM cells into the transmitted STS-3c/1 (STM-1) synchronous

payload envelope.

• Inserts a register programmable path signal label (C2).

• Generates the transmit payload pointer (H1, H2) and inserts the path

overhead.

• 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.

• Optionally inserts externally generated path overhead bytes received via a

576 kbit/s serial interface.

• Optionally inserts externally generated data communication channels (D1-D3,

D4-D12) via a 192 kbit/s (D1-D3) serial stream and a 576 kbit/s (D4-D12)

serial stream.

• Optionally inserts externally generated section user channel (F1) and

externally generated orderwire channels (E1, E2) via three 64 kbit/s serial

interfaces.

• Optionally inserts externally generated transport overhead bytes received via

a 5.184 Mbit/s serial interface.

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

bytes (A1, A2).
