XRT94L55 Overview
Description
The XRT94L55 is a SONET/SDH OC-48/STM-16, 4xOC-12/STM-4, 16xOC-3/STM-1 Framer/Concentrator with integrated CDR's. 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 filtering K1,K2 bytes as required by the standards - Provides 48x48 STS-1 cross-connect between OC48 and OC-12/OC-3 interfaces - Supports Tandem Path Monitoring for Network Failure sectionalization as required by ANSI T1.105 HIGH SPEED INTERFACE.
Key Features
- Provides the highest level of integration and cost savings for Multiplexer/Concentrator applications with on chip CDR's
- 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 both SONET and SDH on all interfaces
