US Patent:

20070274719, Nov 29, 2007
Filed:

Jan 3, 2007
Appl. No.:

11/619267
Inventors:

JULIA GAY FERGUSON - RALEIGH NC, US
THOMAS MICHAEL HOLLAND - RALEIGH NC, US
BILLY CHI-KANG SU - CARY NC, US
Assignee:

ALCATEL LUCENT - Paris
International Classification:

H04J 14/00
US Classification:

398 66
Abstract:

A system, method, and computer readable medium for passive optical network rogue optical network unit diagnostics, comprises, detecting an alarm of a network, correlating the detected alarm to a bandwidth map, and selectively disabling an optical network unit upstream to the detected alarm on the bandwidth map for a pre-determined interval.

US Patent:

20150156014, Jun 4, 2015
Filed:

Dec 30, 2013
Appl. No.:

14/143434
Inventors:

- Murray Hill NJ, US
Julia G. Ferguson - Raleigh NC, US
Assignee:

Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:

H04L 9/08
H04Q 11/00
Abstract:

A manner of authenticating subscriber devices for operation in an optical access network, such as ONUs attempting to access a PON. When a managing node such as an OLT in a PON detects a subscriber device, it sends a request for a text string or password, which is presumably resident on the subscriber device and known to the managing node.The request contains an encryption key, which may, after validation by the subscriber device, be loaded into a register. The subscriber device then uses the encryption key in conjunction with a preferably proprietary and embedded encryption algorithm to encrypt the test string or password prior to transmitting it in reply to the request. The managing node may then evaluate the reply message and the encryption or lack thereof of the text string or password prior to determining whether to authorize access by the subscriber device.

US Patent:

20140369681, Dec 18, 2014
Filed:

Apr 25, 2014
Appl. No.:

14/261957
Inventors:

- Murray Hill NJ, US
Julia Ferguson - Raleigh NC, US
Assignee:

ALCATEL-LUCENT USA INC. - Murray Hill NJ
International Classification:

H04B 10/07
US Classification:

398 27, 398 9
Abstract:

A manner of detecting the presence of alien devices, for example ONUs, that are transmitting upstream in an optical access network such as a PON. An alien detection device, for example a properly configured OLT, supports normal network operation and also monitors a selected performance characteristic. When the selected performance characteristic is evaluated to perform within satisfactory parameters, a protocol that includes a command to subscriber devices such as ONUs to go quiet, for example a rogue check, is executed and a signal detector monitored during the quiet period. An alarm may be generated if an alien device appears to be present.
