  • 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.
