GATEWAY APPARATUS FOR TRANSPORTING ELECTRICAL TELEPHONY SIGNALS

摘要

There are disclosed systems, apparatus and methods for rerouting (Fig. 3) telephony signals in the case of a front card (44) failure through the standby or redundant front cards (44), as well as standby or redundant rear cards (45). These redundant cards are coupled with through or bussed connections at connection areas (28A, 29A) assembled with connectors (P2, rP2) of the Compact PCI(R) Standard). This allows the standby or redundant front card (44) to operate in place of the failed front card (44), using the corresponding rear card (45).
