Description
See #6078 and https://gerrit.osmocom.org/c/osmocom-bb/+/33532
I've configured osmo-bsc/bts with a 850MHz cell on ARFCN 136. I then try to register to it from osmocom-bb/mobile via trxcon and get:
20230628205120086 DL1C NOTICE trxcon(0)[0x61200004f720]{BCCH_CCCH}: L1CTL_DM_EST_REQ indicates single ARFCN PCS1900 136 (l1ctl.c:569)
20230628205120086 DTRXC ERROR trx_interface(0)[0x61200004f8a0]{RSP_WAIT}: ARFCN 32904 not defined (trx_if.c:321)
Some research shows that mobile will do something like "ARFCN 136 | PCS" because SI1 rest octests contains "Band Indicator: 1900" for this cell.
