The BSC subracks are classified into the GMPS, GEPS, and GTCS. This describes the recommended configurations of these subracks in different application scenarios and combination modes.
Configuration of the GMPS (Configuration Type A)
The GMPS is configured in the GBCR. Each BSC must be configured with one GMPS. The GMPS processes the basic services of the BSC, performs operation and maintenance, and provides clock signals for the system. The configuration of the boards in the GMPS varies with the configuration modes of the BSC subracks.
Configuration of the GMPS (Configuration Type B)
The GMPS is configured in the GBCR. Each BSC must be configured with one GMPS. The GMPS processes the basic services of the BSC, performs operation and maintenance, and provides clock signals for the system. The configuration of the boards in the GMPS varies with the configuration modes of the BSC subracks.
Configuration of the GEPS
The GEPS is configured in the GBCR or GBSR. The BSC can be configured with zero to three GEPSs. The GEPS processes the basic services of the BSC. The configuration of the boards in the GEPS varies with the configuration modes of the BSC subracks.
Configuration of the GTCS
In BM/TC separated configuration mode, the GTCS is configured in the GBCR or GBSR. The BSC can be configured with zero to four GTCSs. The GTCS performs transcoding, rate adaptation, and sub-multiplexing.
