“1 TRX require 2 ABIS TS”
Why do you say 1 nibble ?
1 TRX carries 8 radio TS.
Each radio TS (16kbps) is connected to 1 ABIS nibble (16kbps).
Therefore, 1 TRX = 8 radio TS = 8 Abis Nibble = 2 Abis TS.
Read slowly 🙂
You know, I just found out that an easy way to compute how many Abis TS are needed for a BTS (the minimum number, that is).
# of Abis TS = 2.25 x # of TRX
It took me years to finally discover this simple method. Dumb & Dumber & Pix (the Dumbest).
