| PRODUCT DESCRIPTION |
| The Maximum 2111 TM DS3 DVB QAM Modulator, which combines DS3 adapter, DVB TS PID Filter and digital cable QAM (DVB-C) modulator in a single unit. It supports 3 input modes, including DS3 signal from HFC system, ASI and SPI (LVDS) input, and then transmodulates the input signal to digital QAM signal. It also supports 3 output modes, including DVB-ASI output, RF output and DS3 (optional) output. 2111 TM DS3 adapts Ethernet WEB Management interface complying with HTTP protocol, which allows real-time status monitoring and control. It can obtain the PSI/SI information coming from each input port and multiplex them up to 1 TS with PCR Error Correction. 2110 TM DS3 can also be called Multi-protocol TS Processor and QAM transmodulator. It is mainly applied to transmitting DVB-C signal in HFC, MMDS and MUDS systems. |
