However, we are understanding some bits around the MCTR<br>(multi carrier transceiver?), a new MO that appears to be present for<br>every physical RUS (Radio Unit) attached to the DUG 20.<br><br>Let's add what we have learned so far.<br><br>Thanks to Sylvain Munaut for his help with this.<br><br>Change-Id: Ib868358eca12b94c4fcca58e94ec8ab1a4edfda2<br>---<br>M include/osmocom/bsc/abis_om2000.h<br>M
