In order to reciprocally assign telecommunications channels of different capacities, for example an ISDN-D channel and DECT channels in a hybrid telecommunications system, in particular an "ISDN-DECT-specific RLL/WLL" system, with a good (cost-effective) use of the band width and minimal technical outlay (for example by simulating the ISDN channel structure with the DECT channel structure), a DECT-specific Cs channel and a DECT-specific Cf channel are used for transmitting information in the hybrid telecommunications system depending on the amount of information transmitted through the ISDN-D channel.

Why it's free to use
- Filed April 3, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 3, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 3, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
