The QTX-2 device is designed to form 8 transport streams in DVB-C format, transmit selected channels to the frequencies and transmit them to the cable television network. Up to 8 STV-Crypt conditional access system scramblers can be included in the device, which allows organizing a paid access system for watching television programs in cable television networks with the SCR-1 (Scrambler Controller) device. The presence of the built-in multiplexer allows you to transfer programs from any of the inputs of the transport stream (4xASI, 1xGbE) to any output (8xQAM (16-256), 1xGbE). Control and configuration via 100 Mbps Ethernet (web browser). Support for Simple Network Management Protocol (SNMP) allows you to monitor the current state of the device.
