STS-192 SONET/SDH Interleaver/Disinterleaver
Overview and Applications
SONET Processing
The S19201 can be used in either SONET or SDH applica-
tions. On the high-speed side, it interfaces to a STS-192/
STM-64 signal in each direction. On the low-speed side, it
interfaces to four STS-48/STM-16 signals in each direction.
The S19201 can be used in conjunction with AMCC’s
RHINE, MISSOURI, or DANUBE chips for terminating
STS-48/STM-16 payloads.
In the multiplex direction, the S19201 accepts four 16-bit
parallel STS-48/STM-16 (155 Mb/s) signals. The S19201
locates the STS-48/STM-16 frames, descrambles the data,
processes the TOH bytes (or SOH bytes in SDH mode),
muxes the four STS-48/STM-16 tributaries.
This muxed signal, or the STS-192 from the demux input is
then selected as the input to the FRGEN192. The S19201
then generates the TOH bytes (or SOH bytes in SDH
mode), performs frame synchronous scrambling, and out-
puts the data onto a 16-bit bus.
In the demultiplex direction, the S19201 accepts a 16-bit
wide STS-192/STM-64 signal. The S19201 locates frame
in this signal, performs descrambling, and processes the
TOH bytes. This signal is then selected for disinterleaving.

The four tributaries are then output on four 16-bit parallel
interfaces.
A TOH/SOH interface provides direct add/drop capability
for both Section and Line overhead.
On the multiplex side the S19201 generates section and
line overhead. It performs framing pattern insertion (A1,
A2), scrambling, alarm signal insertion, and generates sec-
tion and line Bit Interleaved Parity (B1/B2) for far-end per-
formance monitoring.
On the Demux side the S19201 processes section and line
overhead. It performs framing (A1, A2), descrambling,
alarm detection, bit interleaved parity monitoring (B1/B2),
and error count accumulation for performance monitoring.
High-Speed Interface
On the high-speed side, the S19201 supports 16-bit paral-
lel high-speed interfaces, operating at 622 MHz, on both
the multiplex and demultiplex side.
Low-Speed Interface
On the low-speed side, the S19201 supports four 16-bit
parallel high-speed interfaces operating at 155 MHz.
