A connector assembly comprises a plurality of ports. Each of the plurality of ports is configured to receive a respective connector attached to a respective segment of physical communication media. Each of the plurality of ports comprises a respective media interface configured to receive data from a respective storage device attached to the respective connector. The connector assembly is configured to determine if a first connector attached to a first port included in the plurality of ports is defective by determining if a signal level received on the respective media interface associated with the first port has stabilized after a first predetermined amount of time has elapsed since the first connector was connected to the first port. If the signal level has not stabilized after the first predetermined amount of time has elapsed since the first connector was connected to the first port, the first connector is considered defective.

Dynamically detecting a defective connector at a port

A radio frequency signal distribution module and panel for receiving such a module are disclosed. One module includes a housing having a front and a rear, a radio frequency signal input connection positioned on the rear of the housing, and a plurality of radio frequency signal output connections positioned on the rear of the housing. The module also includes a splitter within the housing and connecting the radio frequency signal input connection to the plurality of radio frequency signal output connections. Certain modules include an active attenuation component connected to and providing programmable attenuation of a radio frequency signal output connection from among the plurality of radio frequency signal output connections. Other modules include a data port on the housing, the data port configured to communicate information about radio frequency signals within the module to a computing system remote from the module.

RF circuit module and panel

A telecommunications apparatus includes a switching matrix. The telecommunications apparatus also includes a plurality of conductive user output locations and a plurality of conductive network input locations. For any given user output location there exists a conductive path coupling the given user output location to a corresponding network input location. The telecommunications apparatus also includes a plurality of switches. For any given conductive path, a switch is interposed therein, and each switch has a first state in which the given conductive path is unaltered, and a second state in which the given conductive path is altered, so that the given conductive path couples the corresponding user output location to the switching matrix. The aforementioned telecommunications apparatus may be networked with other such telecommunications apparatuses.

Telecommunication distribution device with multi-circuit board arrangement

A splitter unit including a chassis containing splitter cards. The splitter unit includes a central processing unit mounting location. The splitter unit also includes test access devices that are inactive when the central processing unit mounting location is vacant. The splitter unit is configured such that the splitter cards provide passive signal splitting even when the central processing unit mounting location is vacant.

Splitter system and test access

A WDM optical system including a media converter module including a plurality of converter cards, each converter card being configured to convert a native signal into an optical signal. The system also includes a panel bracket having an opening and a plurality of fingers, and a cable management panel including a drawer having an interior space. The cable management panel includes a splitter/combiner module mounted in the interior space, and the cable management panel is positioned in the opening of the panel bracket so that a space is defined between the cable management panel and the media converter module.

WDM systems and methods

An interface card adapted to be mounted at the back plane of a splitter chassis. The interface card includes card edge connectors for providing connections with a splitter card. The interface card also includes cable connectors for inputting mixed voice and data, and for outputting data and voice signals. Tracings are provided on the interface card for interconnecting the cable connectors and the card edge connectors. The tracings are configured such that first tracings carrying data signals from the splitter card to the cable connectors do not cross second tracings carrying voice signals from the splitter card to the cable connectors.

Splitter architecture for a telecommunications system

Telecommunications systems are provided which include telecommunications equipment, multi-pair connectors and cables, and management devices for grooming the conductors of the connectors and cables for efficient use of the conductor pairs between equipment. A further management device provides cross-connect fields for the conductor pairs of the system. A chassis may house the grooming device, any cross-connect device, and possibly a POTS splitter device. The grooming and cross-connects may be manually controlled, or electronically controlled, including locally or remotely.

Systems and methods for managing digital subscriber line (DSL) telecommunications connections

An apparatus and method provide for filtering of voiceband and specified tone frequencies of a mixed voice/data signal, such as an Asymmetric Digital Subscriber Line (ADSL) signal. A lowpass filter section passes voiceband content of the mixed signal and suppresses mixed signal content having frequencies falling within a databand of the mixed signal. A bandpass filter section is coupled to or integral with the lowpass filter section and passes the specified tone frequency, such as a metering or billing tone frequency. The lowpass and bandpass filter sections exhibit a combined frequency response that provides for a stopband between the voiceband and the metering tone frequency. The bandpass filter section effectively detunes a frequency response of the lowpass filter section to provide for the stopband. The stopband preferably provides for an insertion loss of 3 dB or greater between the voiceband and the metering tone frequency, and suppresses undesirable mixed signal content having frequencies falling within the stopband. The lowpass filter section and the bandpass filter section may each be implemented to include only passive components, such as passive magnetic components.

Apparatus and method for filtering voiceband and metering tone frequencies of a mixed voice/data signal

A monitor circuit for indicating whether a digital cross-connect bay has a cross-connect jack that cross connects equipment being tested that includes a non-intrusive sensor for sensing current changes in a power feed line of the bay being monitored. The non-intrusive sensor is operatively coupled to a sensor device that generates a signal to activate an external sensor if a current change is detected by the sensor. The sensor device is powered from the same power supply as the bay it is monitoring.
