Arrangement For Discovering The Topology Of An Hfc Access Network
US Patent:
6704288, Mar 9, 2004
Filed:
Feb 23, 2000
Appl. No.:
09/511087
Inventors:
Richard R. Dziekan - North Wales PA
Nicholas D. Lee - King of Prussia PA
M. Lamine Sylla - New Britain PA
Jonathan A. Weinstock - Doylestown PA
Nicholas D. Lee - King of Prussia PA
M. Lamine Sylla - New Britain PA
Jonathan A. Weinstock - Doylestown PA
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04J 314
US Classification:
370248, 370255
Abstract:
A hybrid fiber coaxial (HFC) access network manager is formed to support a variety of functions related to the operation and management of an HCF access plant. The network manager includes a topology discovery module that can function either automatically, or under control of a command from the access network manager, to poll individual network elements to identify their type and location, thus creating a topological map of the network. The polling can be accomplished in either the analog or digital domain.
Hfc Access Network Management System
US Patent:
6711135, Mar 23, 2004
Filed:
Feb 23, 2000
Appl. No.:
09/511090
Inventors:
Richard R. Dziekan - North Wales PA
Nicholas D. Lee - King of Prussia PA
M. Lamine Sylla - New Britain PA
Jonathan A. Weinstock - Doylestown PA

Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04J 314
US Classification:
370242, 370248
Abstract:
A hybrid fiber coaxial (HFC) access network manager is formed to support a variety of functions related to the operation and management of an HCF access plant. The HFC access network manager allows for monitoring of the downstream and upstream transmission paths, and supports the sectionalization of faults. The monitoring can be achieved through a variety of techniques including, but not limited to, monitoring bit error rate (BER), frame error rate (FER), carrier-to-noise ratio (C/N), or any other suitable quality-related signal parameter.
Arrangement For Providing Mediated Access In An Hfc Access Network
US Patent:
6728887, Apr 27, 2004
Filed:
Feb 23, 2000
Appl. No.:
09/511702
Inventors:
Robert R. Dziekan - North Wales PA
Nicholas D. Lee - King of Prussia PA
Jonathan A. Weinstock - Doylestown PA
Nicholas D. Lee - King of Prussia PA
Jonathan A. Weinstock - Doylestown PA
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04L 932
US Classification:
713201, 709225
Abstract:
A hybrid fiber coaxial (HFC) access network manager is formed to include a mediated access system to control each service providers ability to monitor, view and re-configure selected elements within the HFC access network. A database included within the manager contains a mapping between the information service providers and the various network elements for which each service provider is permitted access and/or control. With mediated access, an information service provider has the ability to monitor quality, perform diagnostic tests and configure that equipment which directly supports the provided services.
Monitoring System For A Hybrid Fiber Cable Network
US Patent:
6400863, Jun 4, 2002
Filed:
Jun 6, 2000
Appl. No.:

Assignee:
General Instrument - Horsham PA
International Classification:
G02B 628
US Classification:
385 24, 385 15, 385 39, 385100, 359109, 359113
Abstract:
A monitoring system for a HFC network includes a plurality of âtest pointsâ disposed at various locations throughout the network. Each test point is used to allow for the isolation of communication problems within the network (for example, ingress) and mitigation of the effects of the network problems. By distributing a plurality of test points throughout the topology of the network, only limited sections of the network need to be isolated at any point in time to address the particular communication problem.
