CS19201 Datasheet, PDF (1/2 Pages) Applied Micro Circuits Corporation – STS-192 SONET/SDH Interleaver/Disinterleaver

INDUS
STS-192 SONET/SDH Interleaver/Disinterleaver
Features
• Supports the multiplexing and demultiplexing of STS-48/STM-
16 SONET/SDH signals into an STS-192/STM-64 SONET/SDH
signal.
• SONET/SDH low speed side interfaces compatible with
AMCC’s STS-48/STM-16 devices.
• Supports the transfer of up to four STS-48/STM-16 data
streams, carrying any valid combination of STS-48c/AU-4-16c,
STS-12c/AU-4-4c, or STS-3c/AU-4 SONET/SDH payloads, to
other AMCC SONET/SDH POS/ATM terminating products.
• Provisionable for performance monitoring & regeneration.
• Terminates & generates SONET/SDH transport/section over-
head layers, with TOH/SOH interfaces in both mux and demux
directions, on the high-speed side.
• Provides a 622.08 MHz 16-bit bus interface on the High Speed
line side interface in both the MX and DX directions.
• Provides four 155.52 MHz 16-bit bus interfaces on the low
speed line side in both the MX and DX directions.
• Selectable scrambling/descrambling (X⁷+X⁶+1) of SONET/
SDH frame.
• 16-bit synchronous microprocessor interface for configuration,
control, and status monitoring.
• Supports Automatic Protection Switching (APS).
• 192x192 Cross-connect with STS-1 Level granularity.
Product Brief
Part Number S19201CAI12, Revision 2.9, March 2003
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 pro-
vides a channelized OC-192 solution down to STS-48/STS-12/
STS-3 signal payloads. When used in conjunction with AMCC’s
MISSOURI and DANUBE chips, the INDUS provides a channel-
ized OC-192 to STS-48/STS-12/ STS-3/STS-1 framer/pointer pro-
cessor solution.
The S19201 provides full section and line overhead processing. It
also provides SONET/SDH framing, scrambling/ 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 provided 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 configurations.
Applications
• ATM switches and Packet over SONET Routers
• SONET/SDH Add Drop Multiplexers, Terminal
Multiplexers and Digital Cross Connects
• WDM and DWDM
• Test equipment
