SL91CSH,CSH,Huawei OptiX RTN 950A IDU Board

Huawei RTN 950 IDU Board SL91CSH Overview

The CSH is a Hybrid/Packet system control, switching, and timing board.

The functional versions of the CSH are SL91 and SL92.

Compared with the SL91CSH, the SL92CSH incorporates the following new functions:

MPLS-TP Tunnel OAM
ETH PWE3 packets carrying control words
2.5 Gbit/s backplane bus
VPLSs

CSH boards function as system control, switching, and timing boards on OptiX RTN 950 NEs building Hybrid/Packet microwave networks. In this scenario, CSH boards also groom TDM services and Ethernet services. Like CST boards, CSH boards can function as system control, switching, and timing boards on NEs building TDM microwave networks.

The CSH provides the functions of 10 Gbit/s packet switching, full time-division cross-connection, system control and communication, and clock processing, and provides auxiliary ports and management ports.

The CSH consists of the system control and communication unit, packet switching unit, cross-connect unit, clock unit, and power supply unit.

The CSH can be inserted in slots 7 and 8 in the chassis. The logical slots for the CSH on the NMS are the same as the physical slots.

This section describes the technical specifications of the CSH, including the packet switching capability, cross-connect capability, specifications of clocks and wayside service ports, mechanical specifications, and power consumption.
