Description

Not implemented, but also probably limited interest, except
  • GSM-R heavily uses CSD and might be an intresting niche market
  • some end-to-end encrypted mobile phones also use CSD

This will need the corresponding support in the PHY, of course.


Checklist

  • add the E1/E2/E3 bits to the decoded v.110 frame based on out-of-band knowledge of user bit rate (2400/4800/9600)
  • TS 45.003 coding / interleaving
  • RSL CHAN ACT for CT
  • RA1'/RA1 rate adaptation from/to 64k
  • RFC4040 clear-mode RTP payload
  • TS 45.003: missing TCH/F2.4 channel coding
  • TS 45.003: missing FACCH/[FH]
