iDirect Evolution X7 Remote Satellite Router

The iDirect Evolution X7 remote is the first of iDirect’s next-generation family of remotes. Built on an entirely new multi-core hardware system, the X7 is optimized to deliver best-in-class DVB-S2/ACM and A-TDMA throughput performance.

The X7 also features SCPC on the return and an 8-port embedded switch for managing multiple user groups. The rack-mountable remote comes with multiple choices of embedded power supply units and dual DVB-S2 demodulators with fully independent RF chains. This makes it uniquely suited for a range of enterprise voice and data services while simultaneously receiving multicast channels over the same or a second transponder or satellite – even combining spot-beam HTS capacity and Ku- and C-Band capacity.

X7 Features

  • Up to 100 Mbps of combined inbound and outbound throughput
  • 1 RU high remote chassis fitting in standard telecom racks
  • Licensable 2nd demodulator for multicast traffic
  • Variant power supply module configurations
  • Dual image support and Web iSite for ease of deployment and upgrades
  • Communications-on-the-Move (COTM) support
  • AES Encryption

Comtech CDM-760 Advanced High-Speed Trunking Modem

The Comtech CDM-760 High Speed Modem offers an expansive range of symbol rates (1 ksps to 150 Msps) and data rates (100 kbps to 314 Mbps). Run in a duplex setting, this is a staggering 628 Mbps or 300 Msps.

Coupling these speeds with the native Super Jumbo Frame Ethernet interfaces supporting Ethernet frames from 64 Bytes to >10,000 Bytes and the CDM-760 will process Ethernet frames at a blazing (> 1.2 Million packets / second).

Expanding on the efficient DVB-S2 EN 302 307 standard, the CDM-760 again furthers spectral efficiency with its DVB-S2-EB1 (Efficiency Boost) waveforms. DVB-S2 is widely accepted as the most spectrally efficient standards-based waveforms. With our Efficiency Boost technology (DVB-S2-EB1), you can achieve a 10% – 35% increase in efficiency over the DVB-S2 standard without an increase in power or occupied bandwidth. The CDM-760 accomplishes this task by virtually doubling the number of available MODCODs, introducing three new ROF figures (5%, 10% and 15%) and minimizing implementation loss to near theoretical operation. The CDM-760 is software upgradeable to support future standards including DVB-S2 Efficiency Boost, DVB-S2 Extension and DVB-S3.

Implementing Adaptive Coding and Modulation (ACM) operation allows link margin to be converted to user capacity during non-faded conditions by taking advantage of the actual signal to noise ratio rather than calculated worst case signal to noise.

By using the best encapsulation methods, the CDM-760 further increases throughput by using minimal overhead. In G.703 synchronous mode, users can implement monitor and control over the satellite with no additional overhead. When using Ethernet bridge mode, less than 1% overhead is used for encapsulation.

Additionally, the CDM-760 leverages our powerful DoubleTalk® Carrier-in-Carrier® “Adaptive Cancellation” technology. With the ability to overlay TX and RX carriers, Carrier-in-Carrier enables the operator to establish the perfect balance between bandwidth and power, enabling the best possible use of the satellite resource and reducing operating expenses (OPEX).

These technologies alone offer enormous savings to the ISP and telco operator. When used in combination, however, the savings are astronomical. The innovative high-performance architecture of the CDM-760 allows efficient networking and transport over satellite links while supporting a wide range of applications and network topologies.

ADTEC Digital EN91P Contribution Encoder

The ADTEC Digital EN91P is an ultra-low delay 1080P MPEG 4 AVC/H.264 high definition encoder.

The ultra-low delay mode requires the use of Adtec’s RD70 IRD and delivers picture-to-picture services in 100 milliseconds; The EN91P standard delay mode is fully interoperable with other IRDs making it ideal for mission critical trunking and ad-hoc applications. MPEG 4 AVC/H.264 is significantly more efficient than JPEG making it the CODEC of choice for multiplexed and bandwidth sensitive applications; AVCs inherent interoperability significantly adds to the value of solutions based on this industry standard.

The lightweight, 10 pound or 4.5 Kilo EN91P offers amazing features and specifications in its 1 RU chassis, including redundant AC power supplies, enhanced control and monitoring via its front-panel, a browser and SNMP; video support includes SD, 2D-HD and 3D AVC 422, sixteen channels of phase aligned audio, robust VBI support, reliability and easy of use all for an extraordinary value. In addition to encoding phase aligned audio, the EN91P pass-through support includes PCM, DolbyE (16 and 20 Bit) and Dolby AC3 (2.0 and 5.1).

The EN91P encodes and concurrently transports services via ASI, IP and DVBS/S2. The DVBS/S2 modulator is available in IF or L-band with modulation modes ranging from QPSK up to 32APSK based on software licenses.
