US Patent:

6433988, Aug 13, 2002

Filed:

Nov 5, 1997

Appl. No.:

08/964676

Inventors:

Gregory D. Lowe - Dallas TX
Dale Moore - Sachse TX

Assignee:

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

H02H 900

US Classification:

361119, 361 56, 361115

Abstract:

An apparatus comprises a protection group. The protection group includes components, a signal bus, including segments and connectors, that couple the components. The components also include a plurality of working components, and a protection component. Each connector is included in a working component. Each segment couples two adjacent components. The signal bus is terminated by the protection component. A method comprises generating a first signal from a plurality of working components. The first signal is analyzed by a protection component to determine if any working component is improperly functioning. The protection component transmits a second signal to the plurality of the working components to turn off an improperly functioning working component. Data signals are routed by coupling the improperly functioning working component through a signal bus to the protection component. The data signals are processed by the protection component.

International Classification:

H04L001/00

US Classification:

370216, 370220, 370223

Abstract:

A system and method for protection of virtual connections at the data link layer. The method provides for protection switching in a ring network. The method comprises detecting an error in one of a first and second routes (“the errored route”). Error cells are generated for each virtual connection affected by the detected error. Error cells are transmitted downstream on the errored route. First switch fabric receives the error cells at a downstream network element associated with the errored route. Change in state of the errored route is communicated to a second switch fabric of the downstream network element associated with the other of the first and second routes (the “other route”). When the state of the errored route is worse than the state of the other route, automatically configuring the second switch fabric to establish the other route to be a working route for the virtual connection.

Appl. No.:

8/946760

Inventors:

Gregory D. Lowe - Dallas TX

Assignee:

ADC Telecommunications, Inc. - Minnetonka MN

International Classification:

H04L 700

US Classification:

3408252

Abstract:

The apparatus includes a plurality of components, including a first component, a center component, a component adjacent to the center component, and a last component. The apparatus also includes a first signal source generating a first signal, and a second signal source generating a second signal. The second signal source is separated by one or more components from the first signal source. A first bus couples the first signal source to the plurality of components. A second bus couples the second signal source to the plurality of components. The first and second signals are distributed substantially in-phase to the components.

Appl. No.:

9/027156

Inventors:

Gregory D. Lowe - Dallas TX
Dan Zheng - Plano TX

Assignee:

ADC Telecommunications, Inc. - Minnetonka MN

International Classification:

H04N 116
H04J 304

US Classification:

370222

Abstract:

A network element for a virtual path ring network is provided. The network element includes a first ring interface module with a ring input and a ring output. Further, the network element includes a second ring interface module with a ring input and a ring output. A first bus is coupled to the first ring interface. A second bus is coupled to the second ring interface. The first and second ring interface modules each include a switch fabric that passes packets from the ring input of the interface module to its ring output for packets with a destination address for an endpoint associated with another network element. The switch fabrics of the first and second ring interfaces further pass packets from the ring input to the first and second buses, respectively, for packets with destination addresses for endpoints that are associated with the network element. An access interface module is coupled to the first and second buses that adds and drops traffic to and from the ring network.
