[L] Change in osmo-bts[master]: contrib: Add BER testing tool

by laforge

Attention is currently required from: laforge. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/31967 to look at the new patch set (#4). Change subject: contrib: Add BER testing tool ...................................................................... contrib: Add BER testing tool This implements RTP based GSM BER testing for osmo-bts, implementing ideas described in https://osmocom.org/projects/osmobts/wiki/BER_Testing In short: The command transmits a PRBS sequence encapsulated in RTP frames, which are sent to the BTS, which transmits that data in the (unimpaired) downlink. The mobile station receives the data and is instructed to loop it back in the (possibly impaired) uplink. The BTS receives that uplink, puts in in RTP frames which end up being received back by this very tool. By correlating the received RTP with the PRBS sequence, this tool can compute the BER (Bit Error Rate) of the (possibly impaired) uplink. Doing this with different RF channel model simulators in the uplink allows to establish BER at different levels and channel conditions. Original code by Sylvain Munaut extended with some comments and Automake integration by Harald Welte.

[M] Change in osmo-bsc[master]: pcu_sock: handle multiple BTSs with one BSC co-located PCU (in theory)

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/31618 ) Change subject: pcu_sock: handle multiple BTSs with one BSC co-located PCU (in theory) ...................................................................... pcu_sock: handle multiple BTSs with one BSC co-located PCU (in theory) The current PCU implementation has never been tested with multiple BTS attached to it. This is due to the fact that it has been used exclusively in an BTS co-located setup where naturally only one BTS is present. The PCU sock protocol supports multiple BTSs in theory and we should handle this correctly.
