  • System, device, and method for consolidating frame information into a minimum number of output links
    Patent number: 6181688
    Abstract: 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 signal for consolidation into a frame groomed consolidated circuit. The frame groomed consolidated circuit is transferred to an edge switch (24) in DS-1 signals through the frame groomer (40) and the cross-connect matrix (44).

  • Signaling protocol conversion system
    Patent number: 6084887
    Abstract: A telecommunication system (10) includes one or more subscribers (24) that provide telecommunication traffic in an upstream direction to a D4 channel bank (26). The D4 channel bank provides network interface signals having a first signaling protocol format to a cross-connect (18) over a telecommunication link (28). The cross-connect (18) includes a signaling protocol converter (30) that converts network interface signals having the first signaling protocol format into network interface signals with a second signaling protocol format. The cross-connect (18) passes the network interface signals with the second signaling protocol format to a local digital switch (20) over any of multiple telecommunication links (22a-22n). In a downstream direction from the local digital switch (20) to the subscribers (24), the signaling protocol converter (30) converts from the second signaling protocol format to the first signaling protocol format.
