LAPD stand for LINK ACCESS PROTOCOL ON D CHANNEL.
DAC value is basically defined for the synchronisation of one bts with other and to make a hand over possible intercellular hand over.

can we operate all three sector of nokia ultrasite bts by using only two BB2A?1st May 2006 at 21:26 #42969patrickGuest
daroga parsad – 1 May 2006
1BB2A = 2TRX
3 sectors = 3 TRX you can use 2BB2A but you can add TRX.
I think it is not recommanded by Nokia.
minimum recommanded by Nokia => 3 sectors(222 min) = 6 TRX(min) = 3BB2A
saurabh – 30 Apr 2006
Ultrasite => 666 TRX max
Metro site => 4 TRX max2nd May 2006 at 09:39 #42970utkarsh varshneyGuest

i don’t thing it can be possibe ,two bands in one cabinet.that is why venders has two differnt cabinets.because the internal system is differntfor each one.
other wise our venders will start do manufaturing of dual band cabinets with the name like DBTS or DRBS.3rd May 2006 at 09:09 #42974patrickGuest
