System and method for network using redundancy scheme
First Claim
1. A network system comprising:
- a network interface connected to a first network;
a primary switch connected to the network interface;
a secondary switch connected to the network interface; and
a second network connected to both the primary switch and the secondary switch;
wherein packet-switched data is transferred between the network interface and the second network across the primary switch if the primary switch is operable, and the packet-switched data is transferred between the network interface and the second network across the secondary switch if the primary switch is inoperable.

Abstract
A system and method is provided for transferring packet-switched data across a network. A network interface may be connected to a primary switch and a secondary switch, both of which may be connected to a network. The network interface may also convert between circuit-switched data and packet-switched data. Further, packet-switched data may be transferred between the network interface and the network across the primary switch if the primary switch is operable, and across the secondary switch if the primary switch is inoperable. The system and method may also include a selection switch, route server and controller. Additionally, the system and method may include a primary router and a secondary router. Packet-switched data may be transferred across the primary router if the primary router is operable, and across the secondary router if the primary router is inoperable.

15. A method for transferring packet-switched data comprising:
-
determining if a primary switch and a first link are operable;
transferring packet-switched data across the primary switch if the primary switch and the first link are operable; and
transferring packet-switched data across a secondary switch if at least one of the primary switch and the first link are inoperable. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A network assembly comprising:
-
a digital signal processing card for converting between circuit-switched data and Internet protocol packets;
a primary switch connected to the digital signal processing card;
a secondary switch connected to the digital signal processing card;
a selection switch connected to the digital signal processing card, the primary switch and the secondary switch, wherein the selection switch enables the Internet protocol packets to be transferred across the primary switch if the primary switch is operable, and across the secondary switch if the primary switch is inoperable;
a route server connected to the selection switch, wherein the route server controls the functioning of the selection switch; and
a controller connected to the primary switch, wherein the controller monitors the primary switch and deactivates the primary switch if the primary switch is inoperable. - View Dependent Claims (25, 26, 27)
