AMT70 Modulator<br />
The hub uses the Advantech AMT70 Universal Modem. The AMT70 supports a<br />
broad range of transmission standards including both DVB-S and DVB-S2. As<br />
part of RCS network synchronization, the AMT70 supports NCR time stamping<br />
and synchronization via 10MHz and GPS’ 1pps inputs.<br />
The AMT70 supports the full range of DVB-S/S2 coding and modulation.<br />
Burst Demodulator<br />
The hub burst demodulator is a full IF to baseband multi-carrier demodulator<br />
(MCD). Packaged as a single rack-mount unit, the MCD supports an L-band<br />
interface, per<strong>for</strong>ms frequency de-multiplexing, burst demodulation and decoding<br />
and <strong>IP</strong> reassembly.<br />
Features of the MCD include:<br />
• L-band interface (950 to 2150 MHz).<br />
• Maximum Throughput: 24Mbps<br />
• Maximum Bandwidth: 34MHz<br />
• Supported Traffic Encapsulation Format: 1 & 2 ATM and MPEG<br />
