A telecommunications network (12) includes a digital cross-connect system (10) that receives frame relay information carried in individual DS-0 signals over DS-0 links (14) and/or multiple DS-0 signals over FT-1 links (16). The digital cross-connect system (10) includes a cross-connect matrix (44) that consolidates DS-0 signals into DS-1 signals. The digital cross-connect system (10) further includes a frame groomer (40) that extracts frames from each DS-0 signals for consolidation into a frame groomed consolidated circuit.

Why it's free to use
- Filed December 19, 1997 and granted March 20, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 19, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 19, 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.
