ASCOM TACTICAL openACCESS® NODE C
MOBILE VOICE AND DATA SWITCH FOR
TACTICAL COMMUNICATION SYSTEMS
Ascom Tactical 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 Tactical openAccess Nodes’
connectivity and operational features provide
secure and scaleable 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 C (TAN C) provides interoperable access
functionality towards mobile headquarter communication infrastructures.
It connects local area subsystems with headquarter offices and other
detached control facilities by creating an extended single all-IP network.
This allows fixed line communication equipment and field radio devices to
exchange information that enhance situational awareness.
Ascom Tactical openAccess Node C is a high-performance militarygrade communication network access node with integrated routing
functionality. Supplied in a non-rugged housing with a standard range of
operating temperature, it is the cost effective choice for sheltered environments.
Designed for a large variety of permanent and ad-hoc deployments,
Ascom Tactical openAccess Node C 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.
Upstream DNS server (forwarders) and caching of
DNS queries are supported.
Full featured standards compliant DHCP server
supporting multiple IP subnets.
NTP server and client functionality in order to
provide accurate timing information for
connected devices. Time sources for NTP server
include GPS, remote NTP servers, or local clock.

IP PBX supporting analogue (FXO, FXS, radio),
digital (ISDN, Eurocom), and VoIP (SIP, H.323,
IAX) interfaces. Technology neutral voice
switching core combined with voice application
platform for fast development of customer
specific voice features. Support for direct inward
and outward dial (DID/DOD) with caller-ID.
Full voice gateway functionality including
support for DTMF and caller-ID for all available
analogue, digital, and VoIP interfaces.
Number translation (NT) applied on called and
calling numbers for incoming and outgoing calls.
PBX includes multiple NT hooks in call routing
path, as e.g. one NT per voice trunk. TAN T can be
easily integrated into existing dialing plans.
IAX trunks allow to setup bandwidth optimized
VoIP channel bundles between TAN T nodes. ISDN,
Eurocom, SIP, and H.323 trunks are available for
connecting TAN T to existing telephony
infrastructure, including PSTN.
Number flood searching allows for deploying flat
dialplans.
Conferencing, hotline, MLPP (available July 2011)
