Preliminary
XRT94L55
SONET/SDH OC-48/STM-16, 4XOC-12/STM-4, 16XOC-3/STM-1
FRAMER/CONCENTRATOR WITH INTEGRATED CDR’S
GENERAL DESCRIPTION
REV. P1.0.0
The XRT94L55 is a SONET/SDH OC-48/STM-16,
4xOC-12/STM-4, 16xOC-3/STM-1 Framer/Concen-
trator with integrated CDR's.
APPLICATIONS
• DWDM Multiplexer/Demultiplexers
• Add Drop Multiplexers
• Optical/Digital Cross-Connects
• Router and Switch Line Cards
• Provides Overhead Transparency between low
andhigh speed interfaces
• Supports performance monitoring and alarms
required by GR.253 and ANSI T1.105
• Supports 50 msecond APS by monitoring and filter-
ing K1,K2 bytes as required by the standards
• Provides 48x48 STS-1 cross-connect between OC-
48 and OC-12/OC-3 interfaces
• Supports Tandem Path Monitoring for Network Fail-
ure sectionalization as required by ANSI T1.105
FEATURES
• Provides the highest level of integration and cost
savings for Multiplexer/Concentrator applications
with on chip CDR's
• Provides multiplexing/concentration between OC-
48/ STM-16 interfaces and 4xOC-12/16xOC-3
interfaces
• Provides 4 serial OC-12/STM-4 interfaces with
integrated CDR, compatible with industry standard
optical modules
• Provides 16 serial OC-3/STM-1 interfaces with
integrated CDR, compatible with industry standard
optical modules
• Provides 1+1 protected 4-bit parallel 2.488 Gbits/
sec OC-48/STM-16 interface, compatible with
industry standard CDR/transceivers
• Supports the mappings for any standard combina-
tion of STS-48c/AU4-16c, STS-12c/AU-4c or STS-
3c/AU4 or STS-1/AU3
• Supports both SONET and SDH on all interfaces
• SONET/SDH is programmable per interface
• Provides pointer processing to accommodate tim-
ing offsets between optical interfaces
• Terminates Section Overhead, Line Overhead on
OC-48/STM-16, 4xOC-12, 16xOC-3 interfaces
• Provides options to terminate and/or monitor STS-
Path Overhead
HIGH SPEED INTERFACE
• 1+1 Protected OC-48/STM-16, 4-bit parallel LVDS
compliant with TFI-5 Protocol
LOW SPEED INTERFACES
• SONET/SDH compliant 4xOC-12 interfaces with
integrated CDR meet all the relevant jitter specifica-
tions; OC-12 interfaces are PECL and compatible
with industry standard optical modules
• SONET/SDH compliant 16xOC-3 Interfaces with
integrated CDR meet all the relevant jitter specifica-
tions; OC-3 interfaces are PECL and compatible
with industry standard optical modules
APS INTERFACE
• Provides bi-directional APS Interface for 1 + 1 and
Ring Protection
SECTION, LINE, STS-PATH OVERHEAD INTERFACE
• Provides serial access to all Section, Line and STS
Path Overhead data for OC-48, 4xOC-12 and
16xOC-3 interfaces
• Provides serial access to DCC channels for direct-
connections to standard HDLC processors.
MICROPROCESSOR INTERFACE
• Supports standard 8-bit micro-controllers with Intel
or Motorola style interfaces
• Provides interrupts for alarm processing
