HI Neuil,
Nice Question.I cannopt give you exact things…but for basics..
Between BTS and BSC :
*********************
Number of TS =NTS
Number of PCM = (NTS/4)/30
Round it to next Integer.
Like if you get 0.7 RESULT=1.
If you gert 1.3 RESULT=2.
Thi is not exact but use this for gainming knowledge.In practical…you may see different things.
Between BSC(TRA)-MSC :
*********************
Think that TRA Always inside BSC.
Number of Ater/A Interface PCM =
( Number of Traffic TS in AIR Interface ) / 30.
This is BASICs ok…
