Description
Since some months ago, when connecting osmo-bts-sysmo to a remote osmo-bsc that is not directly on the LAN, (and very occasionally on the LAN), but rather on some higher latency link, I am often seeing
common/oml.c:991 OC=CHANNEL INST=(00,00,00): SET CHAN ATTR: this BTS model does not support TSC 7 != BSIC-BCC 0
Seemingly because in the OML bringup we are sending Set CHAN attrs before we have sent Set BTS attrs
I don't know what controls this sequence, but maybe it would be good if that were a little more robust.

- File bsic_0.pcap bsic_0.pcap added
It might be of help to observe what happens if the TSC is set to 0 so that the OML bring up is not terminated, eventually we do send the set BTS attr. See bsic_0.cap
