RSS-3RV Multiple RF Channel Redundancy Switching station with Video-Audio Monitoring for Automatic Switching
The RSS-3RV RF switching station incorporates (3) three independent 2X1 automatic Broadband RF switches. Each switch module has a separate video input to monitor the main input video Sync (optional Black) level for its automatic switching operation.
The RSS-3RV is a hybrid unit designed to provide redundancy to local TV channels received over fiber and other transport links, when the backup channel is reprocessed and therefore only available as RF modulated channel. This is the case often with off-air local Broadcast channels. In addition, it can be used community channel automation and channel sharing when special events are received over the return-band and reprocessed directly at RF.
Each switch module in the RSS-3RV chassis accepts two RF (CATV) channel inputs to switch automatically to the backup input when the main input video (Sync or Black) level drops below its Threshold setting level. The RSS-3RV thus monitors independently the main input video of each switch for its automatic switching operation and for remote status monitoring and alarm over an IP-Network. An embedded server is also available that allows multi-user remote access for monitoring and switch override/control from a Web-page using any Web browser, with an SNMP protocol for alarming to NOC (Network Operation Center) & remote monitor/control.
The RSS-3RV switches back automatically to the main RF input channel, when the main video signal is restored above its threshold level, with a built-in Hysterisis. Like in all other Tekron RSS automatic switching products, the RSS-3RV incorporates a passive signal bypass to pass the main RF input to the output in the event of power loss to the RSS station.
The RSS-3RV is designed with internal (adjustable) delays before alarming & switching occurs after video sync drop below threshold level, and built-in Hysteresis.
Front panel “status LED” indicates video presence & switch position for each module. A toggle switch is also available for emergency switch override & control. Additionally, the RSS-3RV has Ethernet-IP remote Network monitoring/alarm & switch control capability, with serial port for remote DTMF-tone phone (switch) control via modem over dial-up telephone line with restricted access.
Tekron RSS products offer unique solutions to signal back-up and redundancy in Headend & Hub sites, as well as monitoring and alarm. They address automatic switching applications of CATV RF-Broadband & L-Band feeds, digital ASI/SDI feeds, analog Video, Audio & IF channels, and single CATV channels.
