Clock Synchronisation In GSM Networks
Hello friends, here is the link to my new UDEMY Course on 5G Technologies, Architecture And Protocols and all other courses
This video explains how clock synchronisation is dome in GSM (Global System For Mobiles) network. The MSC can be supplied the clock through the caesium PRC. Some networks may also supply the clock to the MSC through the PSTN networks. The BSC receives the clock from the MSC. The MSC transfers the clock to the BSC. BTS receives the clock from the BSC in a manner similar to the clock transfer from the MSC to
the BSC.
There are a few things that transmission planning engineers should know when planning synchroni-
The clock always flows from the MSC to the BSC and the BSC to the BTS. The MSC gets the clock from the PRC.
r The maximum number of equipments in a chain should be limited; e.g. the number of SSUs should
not be more than 10. Jitter and wander become accumulated when the synchronisation chains are long. To maintain the quality of a synchronisation network, a highly accurate clock should be used as the PRC and there should always be more than one clock source available at all times for the equipment/element
needing synchronisation. This is video is a part of a free training on Global System For Mobiles
