Version Description
The functional version of CSHR boards is SLJ1.
Application
OptiX RTN 910A uses CSHR boards as system control, switching, and timing boards. CSHR boards implement system control, service switching at the TDM/packet plane, and the clock function, and provide service ports and IF ports. Therefore, OptiX RTN 910A configured with CSHR boards can support basic applications without other boards.
Figure 1 Application scenario of CSHR boards
NOTE:
OptiX RTN 910A can use service boards and ISV3 or ISM6 boards to provide extended functions. In this case, the service boards process the related services before sending them to the CSHR. After being groomed by the CSHR, the services are sent to the IF boards for processing and then to the ODU.
Functions and Features
CSHR boards provide 10 Gbit/s packet switching capacity, full time-division cross-connection, system control and communication, and clock processing functions. In addition, CSHR boards provide GE, E1, IF, auxiliary, and management ports.
NOTE:
The CSHR board is non-pluggable.
