The interface between BSC and the BTS is called as Abis interface. its hard to understand ur question…if ur using siemens BTS i can tell u how u calulate the number of trunks required on the Abis interface.
As Sudhir said it is an interface between BTS and BSC. Use Erlang formula to calculate the required resources for the subscribers.
Do not hesitated to contact me if you have further questions.
