STTX
SONET/SDH Transport Overhead Terminating Transceiver
FEATURES
• Monolithic, SONET/SDH Transport
Overhead Terminating Transceiver for
use in STS-1, STS-3 (STM-1), or
STS-12 (STM-4) applications.
• Operates in STS-1 bit-serial mode,
STS-1 byte-serial mode, STS-3/STM-1
byte-serial mode, or STS-12/ATM-4
byte-serial mode.
• Compatible with PM5355 S/UNI-622
physical layer interface, PM5344
SPTX SONET/SDH Path Terminating
Transceiver, and with commercially
available 622 Mbit/s serial-to-parallel
conversion devices.
• Performs byte-interleaved multiplexing
of lower-rate, drop-side, SONET/SDH
data streams.
• Optionally inserts the framing bytes
(A1 and A2) and the STS identification
bytes (C1) in to the transmit stream.
• Performs frame synchronous
descrambling and scrambling.
• Compares the bit-interleaved parity
error detection codes (B1 and B2) for
the receive stream. Inserts B1 and B2
in the transmit stream.
• Inserts line Far-End Block Errors
(FEBEs) into the Z2 growth byte based
on received B2 errors.
• Accumulates near-end errors (B1 and
B2) and far-end errors (Z2).
• Extracts and inserts the order wire
channels (E1 and E2).
• Extracts and inserts the data
communications channels (D1-D3 and
D4-D12).
• Extracts and inserts the section user
channel (F1).
• Extracts and inserts the Automatic
Protection Switch (APS) channel (K1
and K2). The receive APS bytes are
also filtered and extracted into internal
registers.
• Detects Loss Of Signal (LOS), Out Of
Frame (OOF), Loss Of Frame (LOF),
Far-End Receive Failure (FERF), line
Alarm Indication Signal (AIS), and
protection switching byte failure
alarms.
• Inserts FERF and AIS in the transmit
stream.
• Provides LOS insertion, framing
pattern error insertion, and coding
violation insertion (B1 and B2) for
diagnostic purposes. B1 and B2 error
can also be generated “on-the-fly”
using an error insertion mask.
• Provides a transmit and receive ring
control port, allowing alarm and
maintenance signal control and status
to be passed between mate STTXs for
applications in ring-based add/drop
multiplexers.
• Low power, +5 V, CMOS technology.
Device has TTL/CMOS-compatible
inputs and outputs.
• Available in a high performance 208-
pin copper slugged (28 by 28 mm)
Plastic Quad Flat Pack (PQFP)
package.
