HUAWEI CSHN SLB2 Hybrid system control switching and timing board
Product Description:
The functional versions of the CSHN are SLB1 and SLB2.
Compared with the SLB1CSHN, the SLB2CSHN incorporates the following functions:
Multiprotocol label switching transport profile (MPLS-TP) tunnel OAM
ETH pseudo wire emulation edge-to-edge (PWE3) packets carrying control words
Virtual private LAN services (VPLSs)
Application:
CSHN boards function as system control, switching, and timing boards on OptiX RTN 980 NEs. In this scenario, these boards also converge and groom various services using their STM-1/4 and GE service ports.
Figure 1 Application scenario of CSHN boards
NOTE:
In the preceding figure, IF boards can be TDM IF boards, or general-purpose IF boards or XPIC IF boards working in SDH microwave mode if they need to converge TDM microwave services, and they can be general-purpose IF boards or XPIC IF boards working in native E1+Ethernet mode or native STM-1+Ethernet mode if they need to converge integrated IP microwave services.
E1 services shown in the preceding figure can be native E1 services or CES/ATM E1 services, and Ethernet services can be native Ethernet services or ETH PWE3 services.
Service boards shown in the preceding figure can be Ethernet interface boards, STM-1 interface boards, E1 interface boards, or Smart E1 processing boards.
Functions and Features:
The CSHN provides 22 Gbit/s packet switching, full time-division cross-connection, system control and communication, and clock processing functions. It provides GE ports, STM-1/4 ports, auxiliary ports, and management ports.
Table 1 lists the functions and features that the CSHN supports.
