PS1, Line 66: ubit_t
so here the nbytes indicats the number of _input_ bytes. I find that a bit confusing. Maybe call the parameter n_out_bytes / n_in_bytes to make it more obvious? Not critical, but just a thought.

Change subject: csd_v110: properly set bit E2 for TCH/F4.8 NT
......................................................................
Patch Set 3: Code-Review-2
(1 comment)
Patchset:
PS3:
Unfortunately this approach cannot work because bit E7 simply does not exist in NT mode: that bit position gets replaced by one of D-prime bits belonging to the RLP frame. You reference TS 44.021 Figure 1 - but that figure is part of section 10.2.1.1, and that entire part of the spec (all of chapter 10) is applicable only to transparent services. NT services are covered by chapter 12 of this spec instead, plus chapter 15 of TS 48.020 that is more relevant.
The only correct solution is to extend the internal API to `csd_v110_rtp_encode()` and pass a flag that indicates alignment with TDMA multiframe structure.

Ah I didn't see it was a loop, fine then.
