DEV Adds Scheduled switching of RF signals

August 9, 2011

 

DEV America, unveiled new features to its DEV 1951 Dual-Channel Universal Switch Chassis that allow automatically programmed switching according to a daily broadcast or other event schedule.   The product improvements enable cable, broadcast, and satellite technical facilities to more cost-effectively manage their RF (radio frequency) systems. 

By using the Time Switch function of the field-proven Dual-Channel Universal Switch Chassis DEV 1951, modules in the chassis can be activated autonomously and switched precisely according to pre-defined time schedules without requiring an overlaying network management system.  The new feature lets operators schedule “on” or “off” switching of CATV, L-band or ASI signals, according to plans controlled and monitored via an easy-to-use web interface. In only 1RU form factor the compact Universal Switching Chassis DEV 1951 offers two slots to accommodate a wide variety of modules. Typical configurations are two switches for two-channel operation or redundant single-channel switching, or one switch and one passive splitter for a distribution function.

The chassis may be operated locally or remotely via a digital interface using protocols such as SNMP, Leitch, Sandar Prosan, and QEC. The web interface allows access to essential module functions. Using this interface, standard switch modules can be activated and switched autonomously following customer specific timing schedules without intervention of the network management system.
