Feature #4535
openDevelop "E1/Abis generator"
60%
Description
This will then provide a E1 line with 16k (and possibly 8k) sub-slots and TRAU frames for the different voice codecs via libosmo-abis.
It will enable development and testing of osmo-mgw without any external dependencies.
I am also considering to include a RTP to E1 conversion inside that generator, so that a test caes could send an RTP packet to the e1-gen, which would turn it into a TRAU frame that appears on a sub-slot of an E1 timeslot, which then subsquently travels into osmo-mgw, which will perform the inverse operation and re-create a RTP packet. The test suite could then compare the two RTP packets.
Details will be worked out on-the-fly. Right now I'm mainly workin at the I.460 subchannel mux/deumux as well as TRAU frame alignment for all of the modes/codecs.
