S19202 Block Diagram
PRODUCT BRIEF
Part Number - S19202CBI30
Product Brief Revision 3.1 - January 2002
· Supports full duplex mapping of ATM cells or packets for a
single STS-192c/AU-4-64c, four STS-48c/AU-4-16c or six-
teen STS-12c/AU-4-4c SONET/SDH payloads.
· Supports a single STS-192/STM-64 or quad STS-48/STM-
16 line interfaces on the line side and on the protection
port. Each STS-48/STM-16 can support a concatenated
payload or can be channelized down to STS-12c/AU-4-4c.
· Terminates and generates SONET/SDH section, line, &
path layers on the line side and APS port, with transport/
section E1, E2, F1 and DCC overhead interfaces in both
transmit and receive directions.
· Supports independent loop timing when in quad STS-48/
STM-16 mode.
· Supports protection switching (APS) between two Ganges
devices or between two fiber optics modules
· Provides an Optical Internetworking Forum (OIF) SFI-4
compliant 622.08 MHz, 16-bit bus LVDS interface on the
line side in both the TX and RX directions.
· Provides a 64-bit, 200 MHz FlexBus 4 system interface
that supports the transfer of either packets or ATM cells.
· Support mixed ATM and POS data termination, config-
urable on a per-tributary basis
· 16-bit synchronous microprocessor interface for configura-
tion, control, and status monitoring.
· Packaged in a 624-pin CBGA.
· Implemented in .18 micron, 1.8V and 2.5V technology.
The Ganges IC is a highly integrated VLSI device that pro-
vides full duplex mapping of Packets or ATM cells into
SONET/SDH payloads at rates up to 9.95Gb/s.
Ganges provides full section and line overhead processing
for either a single STS-192/STM-64, or four STS-48/STM-16.
It supports framing, scrambling and descrambling, alarm sig-
nal insertion and detection, and bit interleaved parity (B1/B2)
processing. It also provides path overhead processing for
STS-192c/AU-4-64c, STS-48c/AU-4-16c or STS-12c/AU-4-
4c SONET/SDH payloads and includes bit interleaved parity
(B3) processing.
The automatic protection switching (APS) port of the Ganges
supports generation and termination of SONET/SDH section
and line, as well as TOH insertion and extraction. This allows
inter-device protection switching between two Ganges
devices or intra-device protection between two fiber optics
modules.
The Ganges is SONET/SDH standards compliant with
Bellcore GR-253, ITU G.707, and ANSI T1.105 -1995.
Applications
· Core ATM switches and IP Routers (POS)
· ATM, POS and Frame Relay line cards in Edge and Metro
Switches
· Direct Mapping of any traffic type in SONET/SDH STS-192/
STM-64 and STS-48/STM-16 payloads

STS-192 POS/ATM SONET/SDH MAPPER
Product Brief Revision 3.1 - January 2002
Ganges: S19202CBI30
PRODUCT BRIEF
Overview and Applications
SONET Processing
The S19202CBI30 supports either a single STS-192/
STM-64, or four STS-48/STM-16 SONET/SDH on its pri-
mary line interface as well as on its APS port. It provides
full duplex mapping of ATM cells or packets for STS-
192c/AU-4-64c, STS-48c/AU-4-16c, and/or STS-12c/
AU-4-4c SONET/SDH payloads.
A TOH/SOH interface provides direct add/drop capability
for E1, E2, F1, and both Section and Line DCC channels.
On the transmit side the S19202CBI30 generates sec-
tion, line, and path overhead. It performs framing pattern
insertion (A1, A2), scrambling, alarm signal insertion,
and generates section, line and path Bit Interleaved Par-
ity (B1/B2/B3) for far-end performance monitoring.
On the receive side the S19202CBI30 processes sec-
tion, line, and path overhead. It performs framing (A1,
A2), descrambling, alarm detection, pointer interpreta-
tion, bit interleaved parity monitoring (B1/B2/B3), and
error count accumulation for performance monitoring.
The APS interface is a mirror image of the primary line
interface that also operates either as a single STS-192/
or as four STS-48/STM-16 SONET/SDH Line. This
includes TOH add/drop as well section and line monitor-
ing. This APS port can directly interface to a fiber optics
module or to the APS port of a mate S19202CBI30.
ATM Processing
When configured for ATM cell processing, the
S19202CBI30's ATM processor(s) will perform all neces-
sary cell processing as defined by ATM UNI3.1 and ITU-
T I.432.1 and I.432.2.
HDLC Processing
When configured for POS mode, the S19202CBI30's
HDLC processor(s) provide the insertion of HDLC
framed packets into the STS SPE(s)/STM VC(s). The
S19202CBI30 performs HDLC processing as defined by
IETF RFCs 1661, 1662 and 2615. This includes optional
Address/Control field insertion and removal, Frame
Check Sequence (FCS) generation and check, transpar-
ency processing, HDLC frame delineation and optional
X43+1 scrambling and de-scrambling.
The HDLC processor(s) are also compatible with Frame
Relay Forum's FRF.14 specification.
Line-side Interface
On the main line-side and the APS port, the
S19202CBI30 supports a 16-bit parallel LVDS interface,
operating at 622MHz that is compliant with the OIF SFI-4
recommendation and designed to interface to AMCC's
S3091/92 and S3097/98 OC-192 physical layer devices.
For quad STS-48/STM-16 operation, the S19202CBI30
supports four 4-bit, 622 MHz, line interfaces and is
designed to interface to AMCC's S3455 OC-48 physical
layer device.
System Interface
The S19202CBI30 IC provides a 64-bit, 200MHz, Flex-
Bus 4
TM
system interface for the transport of either pack-
ets or ATM cells. The S19202CBI30 also includes a clear
channel mode that enables the direct mapping of system
payload from the system interface into Synchronous
Payload Envelope.
The FlexBus 4 interface complies with the OIF SPI-4
specification.
