SONET/SDH TRANSPORT TERMINATING TRANSCEIVER

1 FEATURES

• Monolithic SONET/SDH Transport Overhead Terminating Transceiver for use

in STS-1, STS-3 (STM-1), or STS-12 (STM-4) line interface applications.

• Operates in one of four modes: STS-1 bit serial mode, STS-1 byte serial

mode, STS-3/STM-1 byte serial mode, or STS-12/STM-4 byte serial mode.

• Provides independent control of the transmit and receive operating modes.

• Performs byte interleaved multiplexing of lower rate drop side SONET/SDH

data streams. STS-3 to STS-1, STM-4 to STM-1 and STS-12 to STS-3

multiplexing modes are supported.

• Processes byte serial data at 6.48 Mbyte/s, 19.44 Mbyte/s or 77.76 Mbyte/s

depending on the mode selected.

• Frames to the receive stream by monitoring the status of the upstream

pattern detector provided by available Serial to Parallel / Parallel to Serial

front end devices.

• Optionally inserts the framing bytes (A1, A2) and the STS identification bytes

(C1) into the transmit stream.

• Optionally descrambles the receive STS-1, STS-3/STM-1 or STS-12/STM-4

stream. Optionally scrambles the transmit STS-1, STS-3/STM-1 or

STS-12/STM-4 stream.

• Calculates and compares the bit interleaved parity error detection codes (B1,

B2) for the receive stream. Calculates and inserts B1 and B2 in the transmit

stream.

• Optionally inserts line far end block errors (FEBE) into the Z2 growth byte

based on received B2 errors.

• Accumulates near end errors (B1, B2) and far end errors (Z2) for

performance monitoring purposes.

• Extracts the order wire channels (E1, E2) of the receive stream and serializes

them at 64 kbit/s. Optionally inserts the order wire channels into the transmit

stream.
