摘要: 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. In this manner, devices with differing signal protocol formats may communication with each other.
