[L] Change in libosmo-abis[master]: libosmotrau: implement RAA' encoder function

by falconia

falconia has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-abis/+/38292?usp=email ) Change subject: libosmotrau: implement RAA' encoder function ...................................................................... libosmotrau: implement RAA' encoder function RAA' is the rate adaption function specific to 14.4 kbit/s CSD services. It is defined in 3GPP TS 48.020 chapter 11, and consists of transforming each user data frame of 290 bits (as it would appear at the radio channel coder interface) into a special A-TRAU frame. 64 kbit/s streams consisting of these A-TRAU frames are meant to traverse the call switching network from one mobile call leg to the other, or from a mobile call leg to an IWF. RAA' transform involves rather bewildering manipulation of payload bit content, done to prevent any possibility of false A-TRAU frame alignment in octet-oriented (no frame boundaries) 64 kbit/s transport. The complexity is such that unit tests are essential, especially unit tests that cross-check our software implementation against those made by others. Fortunately this RAA' function is included in traditional T1/E1 TRAUs, those that support CSD in 14.4 kbit/s mode and implement it according to the specs. Nokia TCSM2 in Themyscira lab includes the necessary support, and the present patch includes a unit test that verifies perfect agreement between our software implementation of RAA' encoder and the historical hw implementation in the old Nokia TRAU.

[XL] Change in pysim[master]: tests: sanitize all cards before running tests

by dexter

Attention is currently required from: dexter, fixeria, laforge. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/pysim/+/38254?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: tests: sanitize all cards before running tests ...................................................................... tests: sanitize all cards before running tests Even though our tests are written in a way that they shouldn't interfere with each other, it may happen that one testrun writes content to a file that upsets a different testrun. The resulting problems are often difficult to diagnose. To minimize the problem, let's reset the cards to a defined state before running the actual tests. This can be done using pySim-shell's export feature. We can generate a backup from a known good state and then play back the backup to reset files that have been changed. Files that didn't change will not be written thanks to the conserve_write feature of pySim-shell.
