SurfBeam® SMTS-1200

Satellite Modem Termination System

The SurfBeam® Satellite Modem Termination System (SMTS) brings you a new generation of affordable Ka-band/ Ku-band wireless broadband services. Based on the open data-over-cable service interface specification (DOCSIS) standard, the SMTS resides at the satellite system gateway, as a direct analog to the cable modem industry’s cable modem termination system (CMTS). The SMTS includes a bank of satellite modulators and demodulators for transmissions to and from remote subscriber terminals. Up to 12 modulator/ demodulator blades fit in each chassis, with each blade containing one 72 Mbps forward channel and eight 2.5 Mbps TDMA return channels.

All real-time scheduling of over-the-satellite traffic is performed by the SMTS, which also provides air interface control for the network. In addition, the SMTS handles the physical LAN interfaces and IP routing protocol support for direct connection of the satellite system into a standard routed TCP/IP terrestrial network.

Specially designed for today’s emerging Ka-band/Ku-band satellite systems, the SurfBeam SMTS provides fast, reliable, high-quality bandwidth-on-demand for a variety of digital communication services. As a component of the SurfBeam Broadband Satellite Access Network, which allows you to offer broadband Internet access to both current and new markets, the SMTS manages traffic between satellite network subscribers and the satellite gateway.
