Description

The RSS-6T automatic switching station incorporates (6) Automatic A/B switches that monitor independently RF-Broadband feeds, with automatic switchover to their respective backup feeds. The threshold level at which the unit switches to the backup feed can be separately adjusted for each input and automatic switch module in the chassis.

The RSS6-T monitors separately the main & backup inputs of each switch module for automatic switching and alarming, and it is designed to prevent automatic switching to the backup input while the main input is below its Threshold level setting. The RSS6-T offers high isolation environment between Broadband input feeds and minimal insertion loss. Input & switch status indications are available at the front panel, with toggle for switch override and control.

Ethernet/IP & RS-232 ports are available at the back of the chassis for remote monitoring, alarm & control. While the SNMP protocol is used for alarming to and remote monitor/control by NOC “Network Operation Center” over the IP-Network, an embedded Web-Server allows regional & local technical personal to remotely access (password protected) for status monitoring and switch override/control from a Web-page using any standard Web browser. The Serial port is used with an external modem to override/control the switch by DTMF (phone) switch control commands over telephone dial-up line.

Features:

• Fail-safe during power loss: When power loss occurs, the RSS-6T switches back or remain in the primary position to pass the main Broadband feed.
• Threshold adjustment: Separate front panel adjusting pot available for each input.
• Hysteresis: Built-in Hysteresis to prevent flutter during automatic switching.
• Switch delay: Optional fixed delay can be added, before automatic switching to the backup input, after the RF dropped below the threshold level setting.
• Optional back-chassis (contact closure) terminal connections are available to interface with existing Monitor-n-Control systems at the remote site to pass monitoring & alarm conditions, and allow remote switch override & control of each switch in the chassis.
• Remote control functions over the IP-Network include commands to disable automatic-return, to allow for example technical staff to resolve an intermittent problem before returning to normal automatic switch operation. Monitoring backup input feed can also be set for alarming only, thus preventing it from affecting the automatic switch operation.
