For terminology and architecture for GSM PLMNs see 3GPP TS 23.002 [2].

Interfaces, interface characteristics, connections through an MSC and ancillary functions of the MSC are defined in 3GPP TS 11.30 [16].

The functions supported by HLRs and VLRs are given in 3GPP TS 11.31 [17] and 11.32 [18].

Each MSC will be responsible for synchronisation, if required, with the fixed network to which it is connected. The requirements of ITU-T Recommendation Q.541 should be observed.

Timing and synchronisation of the radio subsystem is specified in the 3GPP TS 45.010 [4].
