Multiplexed and non-multiplexed configurations should look the same to osmo-bts. The main difference will be on ARFCN settings. Multiplexed (MCBTS) - TRX0 is the primary ARFCN. Channel spacing is fixed at 4, so TRX1 and TRX2 must be set 4 and 8 ARFCN channels higher than TRX0 respectively. Non-multiplexed - ARFCN for each channel can be set within the limitations of the RF device. This will vary depending on the particular RF product. -TT
