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.
BM/TC Separated (Built-In PCU)
In BM/TC separated (built-in PCU) configuration mode, the GMPS must be configured with the GOMU, GTNU, GSCU, GGCU, GXPUM, GDPUP, and GEPUG/GFGUG. The GDPUX, GXPUT, GEIUB/GOIUB/GEHUB/GFGUB/GOGUB, and GEIUT/GOIUT are optional boards.
Figure 1 shows the fully configured GMPS.
BM/TC Separated (External PCU)
In BM/TC separated (external PCU) configuration mode, the GMPS must be configured with the GOMU, GTNU, GSCU, GGCU, and GXPUM. The GXPUT, GEIUB/GOIUB/GEHUB/GFGUB/GOGUB, GEIUP/GOIUP, and GEIUT/GOIUT are optional boards.
Figure 2 shows the fully configured GMPS.
BM/TC Combined (Built-In PCU)
In BM/TC combined (built-in PCU) configuration mode, the GMPS must be configured with the GOMU, GTNU, GSCU, GGCU, GXPUM, GDPUX, GDPUP, and GEPUG/GFGUG. The GXPUT, GEIUA/GOIUA, and GEIUB/GOIUB/GEHUB/GFGUB/GOGUB are optional boards.
Figure 3 shows the fully configured GMPS.
BM/TC Combined (External PCU)
In BM/TC combined (external PCU) configuration mode, the GMPS must be configured with the GOMU, GTNU, GSCU, GGCU, GXPUM, and GDPUX. The GXPUT, GEIUA/GOIUA, GEIUB/GOIUB/GEHUB/GFGUB/GOGUB, and GEIUP/GOIUP are optional boards.
Figure 4 shows the fully configured GMPS.
A over IP (Built-In PCU)
In A over IP (built-in PCU) configuration mode, the GMPS must be configured with the GOMU, GTNU, GSCU, GGCU, GXPUM, GDPUX, GDPUP, GEPUG/GFGUG, and GFGUA/GOGUA. The GXPUT and GEIUB/GOIUB/GEHUB/GFGUB/GOGUB are optional boards.
Figure 5 shows the fully configured GMPS.
A over IP (External PCU)
In A over IP (external PCU) configuration mode, the GMPS must be configured with the GTNU, GSCU, GGCU, GXPUM, GDPUX, and GFGUA/GOGUA. The GXPUT, GEIUB/GOIUB/GEHUB/GFGUB/GOGUB, and GEIUP/GOIUP are optional boards.
Figure 6 shows the fully configured GMPS.
CAUTION: The GDPUX inherits all the functions of the GDPUC. The GDPUX must be configured in any of the following conditions: in BM/TC combined configuration mode, in BM/TC separated configuration mode with the GEHUB/GFGUB/GOGUB configured, or in A over IP configuration mode.
When the number of TRXs to be supported is greater than 256, a pair of GXPUTs must be configured in the GMPS.
The A, Abis, Ater, and Pb interfaces support E1/T1, FE/GE, and STM-1 transmissions. The Gb interface supports E1/T1 and FE/GE transmissions. The previous figures take E1/T1 transmission as examples, where the GEIUA/GEIUB/GEIUT/GEIUP/GEHUB/GEPUG is configured.
