We provide Industry leading technology MFTDMA ,Which provide FULL Mesh HUBLESS Technology .The Product VSAT Plus 3 is designed and industry leading technology for Satcom Applications.

Fully integrated services in a single platform The VSATPlus 3 terminal is based on TDMA with frequency hopping (FHOP). Taking advantage of both time domain and frequency domain access methods, the VSATPlus 3 allows users to support multiple services such as data, voice, and videoconferencing in one simple, integrated IP transport platform.

The single VSATPlus 3 platform integrates with IP based routing and user equipment allowing for a more reliable,flexible, and economical solution. Hubless, full mesh operation within a single satellite hop. The VSATPlus 3 is based on a flexible architecture that supports various network topologies including star, full mesh, hybrid, or any combination of these. 
The VSATPlus 3 architecture eliminates the need for costly central hub equipment and improves call quality by transferring information over single satellite hops.

Satellite IP platform with integrated IP protocol enhancements.

  • Full mesh BoD operation with single satellite hop.
  • Software-controlled adjustable rate satellite modem.
  • Turbo Forward error correction (FEC) with multiple user selectable code rates.
  • L-band or 70MHz IF interface options.
  • Carrier (frequency) hopping on up to 32 carriers
  • Easy terminal installation and low-cost network expansion.
  • Fully automatic acquisition and synchronization operation.
  • Operates with C- or Ku-band radio frequency (RF) systems (other bands optional).
  • No single point of failure for the network due to hubless operation

Modem Redundant Switches

RCS 11

The RCS11 1:1 Redundancy Switch provides simple backup redundancy protection for all configurations of DMD15, DMD20, DMD50 and DMD2050 SCPC modems and the DM240 / DD240 DVB series of Digital Video Modulators and Demodulators. The backup functions of the RCS11 may be performed automatically, manually or from terminal Mode.

RCS 20

The RCS20 M:N Redundancy Switch provides backup switching/protection for up to nine pairs of satellite modem channels (modulators/demodulators). The RCS20 is a companion product to the DMD15/DMD2401/DMD20/DMD50/DM240/DD240 Satellite Modems. The RCS20 is an intelligent microprocessor-controlled system, capable of controlling up to nine modems in a variety of configurations. The RCS20 is comprised of three separate units that make up the switching system; the Redundancy Control Unit (RCU20) shown above, the Digital Data Switch (DDS20), and the Intermediate Frequency Switch (IFS20).
