As mentioned earlier, the capacity of a BSC is mentioned as Radio capacity i.e., how many TRXs the BSC can handle. It simply means using of a Radio interface. For MSC, it has several factors such as the VLR capacity, Inter node Trunks & number of simultaneous switching the MSC can perform. I.m actually giving the very simple principle to calculate. But for MSC, the procedure will go further.
Thank u friends,
