To ensure management of different manufacturers' BTSs from the OMC through the BSC in a standardized way, this BSC interworking ETS relates the OMC-BSC interface (Q3) as specified in GSM 12.20 and the BSC-BTS interface (A-bis Qx) as specified in GSM 12.21. In GSM 12.01 it is required that the BSC performs the Mediation Function between the OMC and the BTS. This ETS defines the requirements for this Mediation Function.
