The S19201 is a highly-integrated VLSI device that provides
for the multiplexing and demultiplexing of STS-48/STM-16
SONET/SDH signals into an STS-192/STM-64 SONET/SDH
signal. When used in conjunction with AMCC's RHINE chip,
the INDUS provides a channelized OC-192 solution down to
STS-48/STS-12/STS-3 signal payloads. When used in con-
junction with AMCC's MISSOURI chip, the INDUS provides a
channelized OC-192 to STS-48/STS-12/STS-3/STS-1
framer/pointer processor solution.
The S19201 provides full section and line overhead process-
ing. It also provides SONET/SDH framing, scram-
bling/descrambling, alarm signal insertion/detection, and bit
interleaved parity (B1/B2) processing.
The S19201 is SONET/SDH standards compliant with
Bellcore GR-253, ITU G.707, and ANSI T1.105 -1995.
A general purpose 16-bit microprocessor interface is pro-
vided for control, and monitoring. The interface supports both
Intel and Motorola type microprocessors, and is capable of
operating in either an interrupt driven or polled-mode configu-
rations.

Overview and Applications
SONET Processing
The S19201 can be used in either SONET or SDH
applications. 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 conjuction with AMCC's
RHINE or MISSOURI 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, descram-
bles the data, processes the TOH bytes (or SOH bytes
in SDH mode), muxes the four STS-48/STM-16 tribu-
taries.
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 outputs 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 disinteleaving. The four tributaries are then
output on four 16-bit parallel interfaces.
A TOH/SOH interface provides direct add/drop capabil-
ity 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 gener-
ates section and line Bit Interleaved Parity (B1/B2) for
far-end performance monitoring.
On the Demux side the S19201 processes section and
line overhead. It performs framing (A1, A2), descram-
bling, 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
parallel 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.
