Now Between BSC-TRA-MSC :-
**************************
BSC Recives those ( 12 PCM TS[64 k] ) 42 AIR TS in 16 K Rate.
BSC Have to transfer them to 64 K Rate for MSC SWITCHING PURPOSE.
BSC connects TRA Internally ( ERICSSON SWITCH).42 AIR TS in 16 K transfered to 42 – 64 K TimeSlot.
So you need 2 PCMs between BSC and MSC ( still arnd 18/19 TS will be free for you ).
…..What do you think guys.
I should charge USD-500 as training FEE.
