20110051596 | SYSTEM AND METHOD FOR ENHANCEMENT OF ETHERNET LINK LOSS FORWARDING - A system and method provide enhanced link loss forwarding in an Ethernet system to determine link degradation and to selectively block and re-establish transport between a near end device and far end device based on link status detection using local packets. When an excessive number of errors are detected in an Ethernet port, a device enters a Links Off mode from a Transport mode where Ethernet ports are turned off at both ends of a circuit associated with the errors. A Block Transport mode is then entered where local packets (e.g., OAM packets) are monitored to evaluate link quality. Transport mode is re-established when acceptable link quality is achieved for a selected period of time. | 03-03-2011 |
20110188514 | METHOD AND APPARATUS FOR AUTOMATED SUBSCRIBER-BASED TDM-IP CONVERSION - An automated conversion method and apparatus are provided to automatically detect the type of an incoming signal (e.g., SONET or Ethernet signal) at a site and to encapsulate outgoing data, or not, based on that detection to facilitate conversion to new infrastructure (e.g., TDM to Ethernet). The automatic detection can be achieved by alternating a search for a SONET signal or Ethernet signal received after a loss of signal or other similar event. Diagnostics of any prior valid transmission are retained in case the disruption was due to transmission quality problem rather than a change in the transmission protocol (i.e. SONET to Ethernet or Ethernet to SONET). The apparatus has an FPGA loaded by a microprocessor with the hardware configuration necessary to support either an IP or SONET configuration when change is detected in the format of the signal arriving at the optical port of the premises device. | 08-04-2011 |
20120294606 | SYSTEM AND METHOD FOR ENHANCEMENT OF ETHERNET LINK LOSS FORWARDING - A system and method provide enhanced link loss forwarding in an Ethernet system to determine link degradation and to selectively block and re-establish transport between a near end device and far end device based on a SONET connection between end devices and link status detection using local packets. When an excessive number of errors are detected in an Ethernet port, a device enters a Links Off mode from a Transport mode where Ethernet ports are turned off at both ends of a circuit associated with the errors. A Block Transport mode is then entered where local packets (e.g., OAM packets) are monitored to evaluate link quality (e.g., SONET bit error rate). Transport mode is re-established when acceptable link quality is achieved for a selected period of time. | 11-22-2012 |
20140133124 | Security Mechanism For Electrical Components - A telecommunication distribution box includes a housing and an electrical component mounted in the housing. A cover plate is movably connected to the housing and is movable between open and closed positions. A lip extends outwardly from the cover plate. The lip covers the electrical component when the cover plate is in the closed position to prevent accessing and removing the electrical component. | 05-15-2014 |
20140268597 | Metro Cell Aggregator Enclosure - A telecommunications aggregator enclosure includes a housing and a cover movably connected thereto. The cover is movable between open and closed positions. A printed circuit board is disposed in the housing. At least one first optical termination is connected to the printed circuit board to receive cables from a base station router. At least one second optical termination is connected to the printed circuit board to receive cables from at least one metro cell. A power supply module is connected to the printed circuit board to supply power thereto. | 09-18-2014 |

Diagnostics of any prior valid transmission are retained in case the disruption was due to transmission quality problem rather than a change in the transmission protocol (e.g., SONET to Ethernet). An FPGA can have firmware configured as necessary to support either an IP or TDM configuration when change is detected in the format of the signal arriving at the optical port of the premises device. | 10-16-2014 |
20150201528 | HEAT FIN FOR SMALL FORM-FACTOR PLUGGABLE OPTICAL TRANSCEIVER MODULE - A small-form pluggable optical transceiver (SFP) device comprising a housing including a main body that houses SFP components, and at least one protruding member that dissipates heat generated from the SFP components, wherein the protruding member extends beyond the main body of the housing. | 07-16-2015 |
