bintec RT1202
High-end ISDN media and VPN gateway
The bintec RT1202 is a powerful and, thanks to its comprehensive equipment, flexible media and VPN gateway. With
its 19-inch metal housing and highly efficient internal switched-mode power supply the fan-free and hard drive-free
design guarantees long-term reliability in critical corporate applications.
Two configurable BRI interfaces (NT/TE) for the use of up to 4 ISDN B-channels and the integrated 4-channel DSP
permit four simultaneous hybrid voice connections (VoIP) and fax traffic (FoIP).
The device has five Gigabit Ethernet ports, which can be configured for LAN, WAN or DMZ, and comes with a licence
for 10 out of a possible 110 hardware-accelerated IPSec tunnels. This makes the RT1202 ideal for use as a media and
VPN gateway in SMEs and company head offices.
Remote CAPI
As the remote CAPI is a network application, which operates independently of the MS Windows© operating system
software, it is ideal for server use. Consequently, CAPI applications can be installed and maintained without suspending
operation and no reboot of the server is required. The software supports 16/32/64 Bit operating systems and
applications. The remote CAPI is also available for Linux.
This function is groundbreaking for the use of virtual machines. MS Hyper-V©, MS virtual PC©, VMware©, virtualBox©
and other virtual platforms do not offer an option to connect ISDN cards. The bintec remote CAPI avoids this problem
and
thereby allows fax and unified communication servers to be operated on virtual systems.

VoIP Media Gateway
With the RT1202 up to 4 telephone calls and fax transmissions (T.38) can be transferred simultaneously between the IP
network and the traditional telephone network. This can be carried out either directly as a terminal adapter (an ISDN
telephone is registered with the VoIP provider) or using a PBX.
A traditional ISDN PABX can be coupled with SIP providers or a modern IP PABX can be operated on the ISDN
BRI/PRI exchange connection. Fax transmission over T.38 is supported in both scenarios. A fax device on the
analogue connection of the traditional PABX can thus send and receive faxes over the SIP provider. This allows FoIP
clients and servers in the LAN to fax over the ISDN exchange.
The G.711, G.726 and G.729A voice coding offered by the SIP trunking and DDI-capable Funkwerk Media Gateway
can be adapted to suit your quality requirements and thereby ensure ISDN quality and high compression. Echoes are
successfully suppressed in G.168.
Fax over IP, T.38, permits implementation of the analogue T.30 group 3 fax protocol.
Thanks to the intelligent quality of service bandwidth management and adjustment, you can prioritise voice traffic over
normal data traffic over the internet, for example, and thereby always ensure sufficient bandwidth for your IP voice
connections.
Pure VoIP calls are not limited and are only restricted in terms of number by the existing bandwidth for the provider.

Routing and VPN gateway
The additional media services, which the bintec RT Series permits, in no way restrict the standard scope of functions of
the bintec R Series. You can use the entire scope of services of the VPN gateway with identical data rates in parallel to
media services.
Bintec gateways have features that go far beyond just IP routing and allow it to be seamlessly integrated into complex
IT infrastructures.
As routing protocols, you can use RIP, OSPF or the Multicast routing protocol PIM-SM for example, and the
comprehensive multicast support makes the device ideal for use in multimedia and streaming applications.
Even the basic equipment provides a SIP application level gateway (ALG) for the direct connection of IP telephones in
the network or for registering with a VoIP provider. The ALG automatically controls the internal firewall making it easier
to configure your VoIP solution, if the media gateway is not active.
