RSS-2T RF Broadband Automatic Switching Station

Transcription

1 RSS-2T RF Broadband Automatic Switching Station The RSS-2T is designed for the redundancy of analog RF channels, QAM RF channels, and CATV RF- Broadband feeds in Headend and Hub sites. The RSS automatic switching station incorporates two (2) independent A/B switches. Each switch module monitors independently its main & backup input feed for automatic switching operation, and remote status monitoring & alarming over TCP/IP Networks. The RSS-2T automatic switch covers a wide input RF level range and incorporates front panel Threshold adjustment for each input being monitored. It can be used to monitor feeds before or after Broadband amplifiers, after Fiber receiver, or monitor a single TV channel or QAM channel in the 5 MHz to 1GHz CATV Band. Because The RSS continuously monitors the main and backup inputs, it will only switch to the backup input feed when the RF level of that input is present and above its threshold setting. The RSS-2T incorporates front-panel switch override capability as well as indication of switch position & level status. An TCP/IP port is available for remote monitoring, alarm and control of the RSS station via SNMP protocol & Web-page. An optional serial port is offered for connection to external modem for dial-up DTMF-tone (phone) switch control in emergency situations. The remote control of the switch overrides in this case, the RSS switch automatic operation as well as the front panel toggle switch. Other RSS models are also offered for automatic switching applications in the Headend and remote Hub sites for the redundancy of: Analog & Digital video/audio channels DVB-ASI & SDI Digital TV Channel feeds Split-Band RF-Broadband feeds RF Broadband feeds L-Band (LNB) Broadband feeds Tekron Communication is specialized and offers solutions to Remote Site Switching Monitoring & Remote Control (SMC) applications in CATV Headend/Hub sites and Broadcast transmission sites. A short list of available models can be found on the last page.
