MOBILE VOICE AND DATA SWITCH FOR
TACTICAL COMMUNICATION SYSTEMS
Ascom openAccess Nodes are integrated
voice and data switches that provide the essential
foundation for today’s mission critical
communications infrastructures. They are used
by national and international military forces,
peace keeping troops and crisis management
teams.
Ascom openAccess Nodes’ connectivity and
operational features provide secure and scale-
able functionality for voice, data and imagery
applications demanded in the combat arena and
homeland security relations.
Built on proven hardware and software
technology, Ascom compact network nodes are
compliant with global industry and governmental
standards for vehicle and military grade
electronics.
In alignment with NATO TACOMS Post 2000 architecture, Ascom
Tactical openAccess Node T (TAN T) provides interoperable access
functionality towards mobile headquarter communication infrastructures.
In mission critical operations this critical communication link assures
information flow at all levels from command headquarters to the troops.
Ascom Tactical openAccess Node T connects local area subsystems
with headquarter offices, other detached command and control facilities
and isolated mobile area sub-systems. By creating an extended single all-IP
network, fixed line communication equipment and field radio devices are
able to exchange information enhancing situational awareness.
Ascom Tactical openAccess Node T is a rugged high-performance
military-grade communication network access node with integrated routing
functionality. With low power consumption it is mechanically designed for
a large variety of permanent and ad-hoc deployments, principally in extreme
field conditions. The watertight ultra rugged enclosure is hermetically sealed
to withstand severe humidity and dust exposure as well as extreme
temperatures. It is corrosion resistant and shock/vibration protected.
Ascom Tactical openAccess Node T can be used to create virtual LANs
even over various transmission technologies, including Ethernet, ISDN,
SHDSL, LOS (Line-of-sight) and satellite infrastructure. QoS routing priorities
can be defined as well as security levels set for secure and efficient traffic
management.

networks, wired and wireless, IP and non-IP, into
one unified All-IP communication domain. This
enables a transparent and robust IP network for
tactical environments, where users can
communicate end-to-end without technology
boundaries.
TAN T supports multiple IP routing protocols, and
can intelligently arbitrate between them.
Multiple tactical network types like Ethernet, E1,
SHDSL, Eurocom, CNR, or WLAN can be connected
to TAN T.
TAN T can be used as autonomous mesh network
node.
TAN T includes non-blocking, full gbit/s line rate
Ethernet switch (optical and copper).
Standards compliant IPSec VPN tunnels for LAN
Ethernet ports supporting multiple authentication and encryption schemes can be established
between TAN T nodes. Available Q2/2011
Multiple VoIP and circuit switched voice
technologies (SIP, IAX, ISDN, Eurocom, Analog)
are supported by the built-in PBX.
The TAN T PBX can convert between all supported
voice technologies, allowing it to be used as VoIP
gateway, e.g. ISDN-to-SIP, or Analog-to-SIP.
Multiple TAN T nodes can build a fully interconnected voice network. Flexible number
translation per voice trunk allows for integration
into different numbering domains.
Routing algorithms optimized for low bandwidth,
high latency radio networks are available and
allow to route traffic over wireless radio
networks.
TAN T provides network services to locally
attached LANs, as DHCP, DNS, and NTP services.
The built-in QoS engine allows for shaping traffic
with prioritization based on DiffServ or 802.1D
classification.
TAN T provides non-blocking, line rate switching
for all LAN Ethernet ports (copper and optical)
including support for 802.1Q VLAN.
TAN T routing engine supports static, OSPF, BGP,
PIM-SM, and IGMP routing protocols. Specialized
routing algorithms are available for mesh
networking and integration of radio networks.
Filtering and redistribution of routes is
supported.
TAN T includes 802.11 a/b/g compliant wirelss
LAN access point. Available Q2/2011.
DiffServ standards compliant IP/Ethernet traffic
conditioning, based on IP DSCP or Ethernet
802.1p fields. Hardware traffic shaper works at
gbit/s line rate.
RFC compliant DNS server supporting dynamic
DNS in combination with included DHCP server.
