HUAWEI CSHC SLA1 Hybrid control units switching and timing board
Product Description:
The functional version of the CSHA/CSHB/CSHC is SLA1.
Application:
CSHA/CSHB/CSHC boards function as system control, switching, and timing boards on OptiX RTN 910 NEs building Hybrid radio networks. In this scenario, these boards also receive and transmit E1/STM-1/FE/GE services. The selection of CSHA, CSHB, or CSHC boards depends on desired port types and port quantities.
Figure 1 Application scenario of CSHA/CSHB/CSHC boards
NOTE:
IF boards shown in the preceding figure must be general-purpose IF boards or XPIC IF boards working in native E1+Ethernet mode or native STM-1+Ethernet mode.
Service boards shown in the preceding figure can be E1 interface boards, STM-1 interface boards, or Ethernet interface boards.
CSHA/CSHB boards must work in conjunction with STM-1 interface boards for receiving and transmitting STM-1 services.
To transmit IEEE 1588v2 packets through Ethernet ports on system control, switching, and timing boards, use CSHD/CSHE boards.
Functions and Features:
The CSHA/CSHB/CSHC provides 4.2 Gbit/s packet switching, full time-division cross-connection, system control and communication, and clock processing functions. The CSHA/CSHB/CSHC provides FE/GE service ports, PDH/SDH service ports, auxiliary ports, and management ports.
Table 1 lists the functions and features that the CSHA/CSHB/CSHC supports.
