I never worked a lot with Nokia, so you may be right. In the 3GPP specs
(and as implemented in Siemens), the BTS initiates the data link to the BSC.
Today I was digging in dahdi-linux docs again and I
see that it uses BKL
mechanisms in the kernel. Is it still valid? Because BKL was removed from
kernels starting from 2.6.39
I'm not sure what you are referring to. I have kernels up to 5.8.0 running
with DAHDI without any problems.
What linux kernel do you use on your server with dadhi
E1 adapters?
mostly whatever version Debian 10 (amd64) ships. I then build DAHDI for that
kernel from source. https://github.com/osmocom/dahdi-linux has a few
fixes for recent kernel versions that upstream doesn't yet have merged to
master. But if upstream compiles on your kernel, you don't need those patches.
