iDirect satellite communications Netmodem

STAR COM satellite communications terminal using iDirect Netmodem  II

Uploads of 128k/256k/512k and 1024k.   Downloads of 512k/1024k/2048k and 4096k.

Designed to use with Internet Cafés for 5, 10 and 20 PC’s and VOIP

New high quality VoIP services have been proven to work well with all these systems

Simplicity

  • One-Box Solution (Satellite Modem, IP Router, TCP Optimization, QoS, Star Com Encryption)
  • Centralized Management (Software Upgrades, Configuration Changes)

Most Reliable Solution over Satellite

  • First to implement Turbo Product Code (TPC)
  • Forward Error Correction 10-9 or Better Bit-Error-Rate Guarantee
  • Uses 50% lower power (Eb/No) when compared to RSV
  • Auto Power Adjustment provides reliable connectivity even in bad weather conditions
  • The ultimate result is more TCP throughput Performance
  • Highest TCP/IP throughputs in the industry (9.1 Mbps downstream - 4.2 Mbps Upstream
  • TCP/IP is very sensitive to BER. TPC Encoding ensures 10-9 BER, providing fiber like reliability Technological Superiority Allows Use of Much Smaller Antenna Sizes

TCP Performance Improvements

  • Mitigates the effects of latency over satellite
  • TCP Acceleration - Reduces overall bandwidth requirement, while enhancing performance
  • 3-Way Handshake Acceleration - Provides better HTTP performance
  • Local DNS Caching - More User Satisfaction

 

Quality of Service

  • Traffic Prioritization based on multiple parameters (Source/Destination IP Address, Source/Destination Port Number, Protocol Type)
  • Class Based Queuing - Assign percentage of bandwidth to each class
  • Rate Limiting - Allocate only bandwidth that is needed
  • Committed Information Rate - Dedicate bandwidth as required (Static and Dynamic)
  • Easily Support VoIP and VTC
  • TDMA/iSCPC Turbo Code FEC
  • L-Band (C/Ku/Ka Band) Variable Data Rates
  • CIR/Dynamic CIR QoS/Firewall
  • IP Router VLANs
  • DNS Caching DHCP/NAT
  • TCP/Web Acceleration RTTM Features
  • 3DES Chipset Onboard Mobile Mode
