Abstract
Abstract A local area network interface for a network element having redundant processors is made by using a pair of connectors for each processor. A delay line is used between pairs of connectors for non-redundant LAN configurations. For redundant LANs, the delay line is not used.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
67 words
A local area network interface for a network element having redundant processors, comprising: a first pair of connectors connected to a first node for connection to a first one of the redundant processors; and a second pair of connectors connected to a second node for connection to a second one of the redundant processors; and a delay line connectable between the first node and the second node.
Claim 2
Dependent Claim
67 words
A local area network interface for a network element having redundant processors, comprising: a first pair of connectors connected to a first node for connection to a first one of the redundant processors; and a second pair of connectors connected to a second node for connection to a second one of the redundant processors; and a delay line connectable between the first node and the second node.
Claim 3
Independent Claim
130 words
A method of providing a network element interface for a local area network, comprising the steps of: providing a separate pair of connectors for each of a plurality of network element processors; connecting each separate pair of connectors to a correspondingly separate node within the network element; connecting each node to a corresponding network element processor; and connecting a connectable delay line between a first pair of connectors and a second pair of connectors for providing a selected delay between the corresponding network element processors used as redundant processors wherein one of the first pair of connectors is for connection to an input line of the local area network and wherein one of the second pair of connectors is for connection to an output line of the local area network.
Claim 4
Independent Claim
130 words
A method of providing a network element interface for a local area network, comprising the steps of: providing a separate pair of connectors for each of a plurality of network element processors; connecting each separate pair of connectors to a correspondingly separate node within the network element; connecting each node to a corresponding network element processor; and connecting a connectable delay line between a first pair of connectors and a second pair of connectors for providing a selected delay between the corresponding network element processors used as redundant processors wherein one of the first pair of connectors is for connection to an input line of the local area network and wherein one of the second pair of connectors is for connection to an output line of the local area network.
Claim 5
Dependent Claim
27 words
The method of claim 2, wherein each separate pair of connectors is for connection as an input and output connection pair for corresponding separate local area networks.
Claim 6
Dependent Claim
84 words
The network interface of claim 1, wherein the delay line is connectable between the first and second nodes by means of: a first pair of jumper connections, a first jumper connection thereof connected to the first node and a second jumper connection thereof connected to a first end of the delay line; and a second pair of jumper connections, a first jumper connection thereof connected to the second node and a second jumper connection thereof connected to a second end of the delay line.
