L1 TCH code status

Hi, Just a quick update for those that don't follow the git or IRC: A few days ago, I merged most of was in my sylvain/testing branch into master. It's now in a state where you can place a call on a BS11 or nanobts. It took a while for me to go from the raw prototype from Dieter to a state I was happy with. (especially because I wanted to understand the purpose of every line I was rewriting since my main goal is to learn :) There were also some extensions (mode switching / bugs fixes / partial HR support / ...). There are still somethings that are only in my testing/ because they're hacks (or even missing): - SIM support: The code is clearly [WIP]. I may get to cleaning it myself at some point, but that's not a priority for me ... - TS change fixup: There is a bug when going from a high TS to a low TS that's tricky to fix. I'm still thinking about the best way to handle this. There is a hack to work around it in my testing branch. This case can't happen on nanoBTS or BS-11 but it may happen on a real network. - TOA loop: I want to check if I can re-use the common code from our AFC/AGC loop rather than adding some other regulation stuff. - Enabling HR: Well ... it doesn't work yet, so no point in putting it in master :) All theses will be added when I have the time to do it. Cheers, Sylvain Munaut
