Dual Optimized M7 Satellite Modems from Datum Systems

March 24, 2015

Datum Systems, an industry leader in advanced bandwidth efficient and high performance SCPC satellite modems announces a key technology partnership with XipLink to embed their latest generation of optimization software (XipOS 4.3) into its M7 Series modems. XipLink is the technology leader in wireless link optimization and a previous Technology of the Year Award recipient by the World Teleport Association.

By tightly integrating the XE-Series wireless optimization software within Datum Systems’ highly
efficient satellite modems, which already offers carrier cancelling, sharper carrier roll-off’s and
sophisticated low latency coding schemes, Datum Systems’ modems will now accelerate and
compress TCP/UDP data for maximum capacity.

“The more than double throughput capability of Xiplink’s optimization software coupled with Datum
Systems’ more than 50 percent carrier bandwidth savings makes the M7 a true Dual Optimized
modem and a win-win for our customers. Xiplink’s powerful optimization and advanced streaming
compression capabilities with our reliable high performance modems allows us to provide greater
throughput and network efficiency to satellite based IP networking customers than ever before, just
what today’s wireless users require,” said David Koblinski, Vice President of Datum Systems.

“We are excited by the flexibility and lower capital cost this partnership will bring to Datum Systems’
growing customer base. The XE-Series software will also include XipLink Real Time (XRT)
functionality to further extend and improve the current high performance Datum Systems line of
satellite modems,” said Bruce Bednarski, Senior Vice President for XipLink. “Technical enhancements
such as XRT will compress, coalesce and prioritize VOIP and UDP for significantly more bandwidth
and packet efficiency without compromising quality. XRT can provide bandwidth savings up to 50%
on this traffic classification.”

XipLink has enjoyed a very close technical and commercial partnership with Datum since 2012 when
both companies collaborated to deliver XipLink's TCP acceleration and compression functionality into
Datum's PSM modems. With Datum's evolution to the M7 series modem, customers will still have
access to TCP acceleration and compression functionality but now delivered on a significantly more
powerful platform capable of supporting the complete portfolio of XipLink's wireless link optimization

New high performance features such as byte-level caching and advanced cellular compression (ACC)
will deliver sizeable reductions in the amount of bandwidth required to transport applications in several
high growth vertical markets. For instance, byte-level caching reduces required bandwidth
requirements by approximately 80% on repeated traffic including images, audio and video. Advanced
cellular compression can reduce header and payload transport by up to 40% on both 3G/4G voice
and data content as it traverses the network connection.
