Description

​SSQ2CXL417 Version Description

The CXL4 is available in several functional versions. The functions provided by the functional versions are different.

Item Description
Functional versions The CXL4 is available in two functional versions, namely, Q2 and Q3. The Q3CXL4 is discontinued.
Differences
  • Interface specifications: receipt of NE ID check results.
  • Maintenance features: CF cards.
  • DCC processing capability.
  • Others: transparent transmission of DCC overhead information over external clock interfaces.
Substitution The Q5CXLLN can substitute for the Q2CXL4 that operates at the same line rate by using the board version replacement function, but active and standby boards must be the same, Q5CXLLN boards or Q2CXL4 boards.
SSQ2CXL417 Application

 

The CXL4 provides service processing, service grooming, clock input/output, and communication control functions in the OptiX OSN system.

The CXL provides the other boards in the system with the timing information, processes the SDH signals, grooms the services between line boards or tributary boards, communicates with the other boards in the system, and performs the configuration and management functions for the other boards in the system.

 

SSQ2CXL417 Functions and Features

 

The CXL4 processes SDH signals, controls communication, grooms services, and inputs/outputs clock signals.
