Description:
The TANDBERG TT4021 Redundancy Controller provides 1+1 redundancy switching combined with the advanced error detection and monitoring capabilities of the TT4000 Transport Stream monitoring family.
Rather than monitor the health of individual hardware units the TT4021 actually monitors the incoming transport stream for health giving a more reliable and robust redundancy switch. The versatility of the TT4021 and wide range of input options negates the need for external converters making the unit even more cost effective. |
Features:
• DVB ASI and other input options
• Robust relay based switching: signal integrity independent of power supply
• Spare input source is checked before switching
• 2 x 1 real-time TS monitor switching
