Abstract
Apparatus is used in communicating in a data and voice communication system. The apparatus includes a line card and a crosspoint switch in communication with the line card. The apparatus also includes an accelerator card in communication with the line card and the crosspoint switch. The crosspoint switch is configured to provide a redundant communications path between the line card and the accelerator card.
Claims9
An apparatus comprising:
- an interface circuit for sending and receiving information over an interface;
- a processing circuit in direct communication with the interface circuit for processing information received from the interface circuit;
- and
- a crosspoint switch in communication with the interface circuit and in communication with the processing circuit, the crosspoint switch providing a redundant communications path between the interface circuit and the processing circuit upon failure of the direct communication;
- wherein the direct communication does not pass through the crosspoint switch.
2 more elements
An apparatus comprising:
- at least two interface circuits including a first interface circuit and a second interface circuit for sending and receiving information over interfaces;
- at least two processing circuits including a first processing circuit and a second processing circuit, the first processing circuit in direct communication with the first interface circuit and for processing information received from the first interface circuit, the second processing circuit in direct communication with the second interface circuit and for processing information received from the second interface circuit;
- and
- a crosspoint switch in communication with the at least two interface circuits and in communication with the at least two processing circuits, the crosspoint switch providing a redundant communications path between the first interface circuit and the first processing circuit upon failure of the direct communication between the first interface circuit and the first processing circuit and providing a redundant communications path between the second interface circuit and the second processing circuit upon failure of the direct communication between the second interface circuit and the second processing circuit;
- wherein the direct communication between the first interface circuit and the first processing circuit does not pass through the crosspoint switch and wherein the direct communication between the second interface circuit and the second processing circuit does not pass through the crosspoint switch.

- at least two interface circuits including a first interface circuit and a second interface circuit for sending and receiving information over interfaces;
- at least two processing circuits including a first processing circuit and a second processing circuit, the first processing circuit in direct communication with the first interface circuit and for processing information received from the first interface circuit, the second processing circuit in direct communication with the second interface circuit and for processing information received from the second interface circuit;
- and
- a crosspoint switch in communication with the at least two interface circuits and in communication with the at least two processing circuits, the crosspoint switch providing a redundant communications path between each of the at least two interface circuits and any one of the at least two processing circuits upon failure of the direct communication between an interface circuit of the at least two interface circuits and a processing circuit of the at least two processing circuits;
- wherein the direct communication between the first interface circuit and the first processing circuit does not pass through the crosspoint switch and wherein the direct communication between the second interface circuit and the second processing circuit does not pass through the crosspoint switch.
