20090142054 | SONET multiplexer card having front panel access to electrical and optical connectors for use in compact enclosure for SONET multiplexer cards - A reduced size multiplexer and, in particular, a reduced size SONET multiplexer module is provided for use in a reduced size enclosure. The SONET multiplexer module has electrical and optical connectors on its faceplate to provide ease in access without having to remove the SONET multiplexer from the enclosure. The SONET multiplexer circuit is configured in a standard Type 400 mechanics circuit board arrangement. The SONET multiplexer module therefore can be inserted into an enclosure in a direction opposite to that in which the DS1 or DS3 connector projects from the face plate, so that the DS1 or DS3 connector remains freely accessible outside of the enclosure when the SONET multiplexer module is fully loaded into the enclosure. DS1 and DS3 cables and optical fibers can thus be easily coupled to the DS1 and DS3 and optical connectors, respectively, when the SONET multiplexer circuit is fully loaded into the enclosure. | 06-04-2009 |
20110069608 | System for providing backup programming at radio or television transmitter - A system transmits backup programming media in a transmitter station being connected to a remote media station. The media station includes a media programming input to receive a source media signal, which includes media programming. The media station further includes an Ethernet programming input that receives an Ethernet media signal including backup media programming being different the media programming. A transmitter station receives the source media signal via a transmission medium and transmits the media programming. The transmitter station further receives the Ethernet media signal and stores the backup media programming in a storage device. A controller detects a fault on a transmission medium connecting the media station and the transmitting station. The controller retrieves the stored backup media programming and generates a backup media signal. A transmitter transmits the backup media programming based on the backup media signal until it is controlled to re-transmit the source media signal. | 03-24-2011 |
