develop software for E1 framing / deframing, CRC4, alignment FSM
I've been writing some code for the framing/deframing for basic frame and crc4-multiframe, as well as Rx + Tx side of CRC4 handling, alignment FSM, ...
It can be found in the
laforge/software branch of osmo-e1-xcvr. See http://git.osmocom.org/osmo-e1-xcvr/log/?h=laforge/software
TODO is mainly: testing of various modes (crc4/non-crc4, ...) as well as any interop tests with real-world E1 out there. My reading of the spec may very well be wrong
