It depends on the TRX’s configuration, e.g. if u the following distribution:
TRX2: SDCCH +7TCH
then (6+7+8+8=29 for full rate & 29*2=58 for half rate) subscriber can talk at the same time & (8+8=16) subscriber can make call setup at the same time. So, it highly depends on the TRX channel configuration.

this column is very much helpful for me to know the details of BSS.i thank all of u for this(esp PIX).3rd June 2008 at 20:03 #35399pixGuest
In NOKIA BTS, i guess you can achieve abot 14 TRX per Abis link, max. Approximatively… it depends hat kind of RSL and OML multiplexing you want to use. it also depends on how many cells : one cell with many TRX’s takes less Abis timeslot than several cells with less TRX/cell.
i’m not nokia, so i can’t say the exact value. Why don’t you ask them directly ??25th June 2008 at 04:35 #35400Dear SirGuest
