Cards designed to save bandwidth, operate with
unique DoD equipment
Wallingford, CT (USA) - DNE Technologies, a provider
of tactical voice and data communication solutions, announces the
release of new interface cards for its TAC Multi-Service Access
Concentrator Line. These cards, a High-Speed Circuit Emulation Services
(HS-CES) card and a full series of V.34 FNBDT Secure Compressed
Voice cards, are designed to support newer Department of Defense
(DoD) communications needs while increasing bandwidth performance
for the user.
DNE's new HS-CES card offers four ports of serial
data traffic, supporting a full concurrent 20Mb per port. This interface
allows newer, higher speed equipment, such as cryptographic units
and routers, to interface over a network at higher speeds than previously
supported. Using an enhanced dynamic bandwidth allocation functionality,
these cards can allocate and release bandwidth for short events,
such as video teleconferencing, without operator intervention. This
results in high quality performance of serial applications while
freeing up bandwidth for other data and voice applications when
the bandwidth is not in use.
DNE's new V.34 Future Narrow Band Digital Terminal
(FNBDT) Secure Compressed Voice cards support the transport of secure
voice telephony traffic based on FNBDT. This new class of encryption
is rapidly replacing older STU and STE type devices. Currently,
a Secure call typically requires 64k of transport in most devices
- or at least 16k in the most effective compression devices currently
in use. DNE’s cards are unique in that they allow the traffic
to pass at its native modem rate of 4.8k, resulting in a 65% over
the best compression technology currently deployed. In addition,
DNE has introduced a 2.4k MELP compressed voice algorithm for a
non-secure call so that users can enjoy the additional throughput
in both secure and non-secure modes while actually improving the
quality of the voice call. DNE is offering these cards in FXS, FXO,
E&M, T1 and E1 versions.
These new interfaces can be used in DNE's TAC
Multi-Service Access Concentrator product line. The TAC-300 and
TAC-900 models allow legacy and modern Department of Defense (DoD)
efficient access to bandwidth constrained satellite circuits as
well as to today's modern high-speed networks. They offer an affordable
transition toward end-to-end networking while retaining support
for critical applications, including Secure Voice, encryption, legacy
serial, and CDI devices.
DNE's TAC Multi-Service Access Concentration
product line concentrates and switches voice, data, and video onto
a network. The line consists of two models: TAC-300 and the TAC-900
both of which support speeds up to 155Mbps OC-3c/STM-1. In addition
to the new interfaces, all models offer a broad selection of network
and user interfaces, including 20Mbps Serial ATM, IP-LAN, Video,
Ethernet, PBX, Framed Services, Native ATM, and Circuit Emulation.
The DNE TAC product line features IP transport,
native ATM cell switching, PVC/ S-PVC/ SVC/A-SPVC connection flexibility,
analog and digital voice support, virtual LAN and data router access.
They also support Unspecified Bit Rate (UBR), Variable Bit Rate
(VBR) and Constant Bit Rate (CBR) ATM Services.
DNE’s Manager of Marketing Peter Gladis
stated, "The release of these state of the art interfaces demonstrates
DNE's commitment to the DoD’s evolving network challenges.
They can also support other emerging critical communications needs,
such as Homeland Security and Emergency Response Teams requirements.
DNE recognizes its customers require a reliable network, maximum
bandwidth availability, and Secure communications. These cards,
designed for our successful TAC Multi-Service Access Concentrator
line, address all three requirements." Mr. Gladis added, "These
interfaces complement DNE's other new option cards, such as a Secure/Compressed
Voice card suite. We truly offer the DoD a complete, reliable communication
solution that is ready to provide real benefits – NOW."
DNE has also recently released a new CV-MCU
NRZ-CDI/Fiber converter line, with both electrical and fiber-optic
interfaces that allow standard NRZ devices to interface with CDI
networks. DNE also continues to manufacture its widely-installed
AN/FCC-100 multiplexer.
