An intelligent network patch field management system is provided that includes electronic hardware, firmware, mechanical assemblies, cables, and software that provide visible and audible cues for connecting and disconnecting patch cords in an interconnect or cross-connect patching environment. Systems of the present invention also monitor patch cord connections in a network.

Intelligent inter-connect and cross-connect patching system

A system for managing and documenting a local area communications network is provided which deploys power sourcing equipment and powered devices by the use of active electronic modules, having an Ethernet controller and Power over Ethernet forwarding capabilities, as integral, managed components within the cable plant, to enhance management, documentation, security and emergency 911 aspects of the network as well as extending the physical reach of the network.

Network managed device installation and provisioning technique

Systems and methods for managing a network

A powered patch panel (PPP) is disclosed that inserts power in mid-span regions of a network and provides fault-tolerance at the power supply level and the power-plane level. Information such as physical location, port status and policy enforcement information may be locally stored and utilized by a processor of the PPP to achieve network control and monitoring. A network management system and/or element management system may be provided to interface with processors of PPPs to achieve network monitoring, control and policy enforcement goals.

Powered patch panel

An arrangement and method for switching a single destination data channel to a different destination without losing any data messages. Such a switch is required, for example, when a switch is made to a standby control unit and the messages originally destined for the original active control unit must be sent to the standby. Received messages are drained from the source prior to making the switch. Appropriate data is copied from the active unit to the standby so that the standby unit is in a state to start accepting newly queued messages from the source.

Arrangement for changing the destination of single link, single destination data messages

In order to provide reliable backup memory for the operational memory (RAM) of a control unit, two segments of a memory with write protect facility are used. Only one of these segments contains the backup memory at any one time, but the other segment may be updated with a new release. Write protect is removed from one of these segments only when an update is taking place. The software for controlling initialization of the operational memory from the backup memory is stored in the backup memory. Extensive checks are performed before accepting an update of the backup memory or an initialization of the operational memory.

Backup memory for reliable operation

An Electrically Erasable Programmable Read Only Memory (EEPROM) provides backup and initialization data for random access memory (RAM) in a control unit. In order to update the EEPROM with new releases of a program and data, the EEPROM is divided into two segments, each with a separately controllable write enable voltage. Advantageously, this allows a new release to be written into one segment of a single EEPROM without erasing the other segment until the newly written segment has been verified.
