ADVANCED PRODUCT BRIEF
STS-48/STM-16 SONET/SDH Framer and ATM/POS Mapper
Features
• Provides two SONET/SDH line interface modes of operation:
single STS-48/STM-16 or quad STS-12/STM-4s.
• Processes any valid combination of SONET/SDH STS-48c/
AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU-4, or STS-1/AU-3
tributaries within an STS-48/STM-16 or STS-12/STM-4.
• Alternatively, this TDM port can be used to support protection-
switching configurations between two OHIO devices or two
fiber optics modules.
• This 4x622MHz APS/TDM drop/add interface supports both
synchronous and asynchronous operation.
• Terminates/generates SONET/SDH section, line, and
optionally path overhead. SONET/SDH processing of all
defined TOH/POH bytes, compliant with Bellcore GR-253 and
ANSI T1.105, and ITU G.751, G.783, G.804.
• Performs full-duplex mapping ATM cells or packets for up to
48 payload tributaries. These tributaries can range in size
from STS-48c/AU-4-16c down to STS-1/AU-3.
• Supports full-duplex mapping of ATM cells or packets into
DS3 tributaries for ATM over DS3 or packet over DS3 applica-
tions. DS3 tributaries are then mapped into either STS-1s or
STM-1s via AU-3.
• ATM mapping is compliant with the ATM Forum UNI 3.1 speci-
fication and ITU-T I.432.1 and I.432.2.
• POS mapping is compliant with IETF RFC 2615.
• Built-in 144x48 cross-connect capability in the TX direction.
Supports ring architectures such as add-drop, drop and
continue, and hairpinning, as well as APS.
• Provides a four bit 622 MHz line interface on the SONET/SDH
side for STS-48/STM-16 applications; four serial 622 MHz
signal for STS-12/STM-4 applications
• Supports independent loop timing in quad STS-12/STM-4 line
configuration
• Provides a 100 MHz 32-bit Flexbus-3TM system interface;
supports Utopia Level 3 mode for ATM applications; for packet
operation, can be provisionned either in extended Utopia-3
mode or in OIF SPI-3 mode.
• Programmable Utopia/FlexBus-3TM addresses for multi-PHY
operation.
• Supports simultaneously ATM, POS, TDM and direct-mapped
traffic on a per tributary basis.
• Loopback capability for SONET/SDH, ATM and POS
tributaries
• Provides a single 4x622 MHz telecom bus type system
interface for add/drop of payload tributaries containing TDM
traffic. This interface includes a 144x48 STS-1 level cross-
connect for grooming of TDM tributaries.
• Packaged in 624 pin CBGA
• 0.18um CMOS, 1.8V core and 2.5V I/O supply
