You can do all that you want with internal crossconnection between BB2A and TRX.
But you don’t respect a logical idea. I advice you to respect a logic.5th May 2006 at 06:27 #42976daroga parsadGuest

I make a mistake: You can use 1BCF and 1 PCM.
But your BTSmix will have 6 sectors: ABDCEF
ABC for 1800mhz
DEF for 900 mhz13th May 2006 at 16:42 #42983HELDERGuest
