bintec RS232bw
Universal router with integrated ADSL 2+ modem, ISDN and 11n WLAN
The bintec RS232bw is a powerful and, thanks to its comprehensive equipment, flexible router. The integrated ADSL 2+
modem on the RS232b supports Annex B (ADSL over ISDN), which is predominantly used in Germany, in accordance
with ITU G992.1 and is compatible with Deutsche Telekom's U-R2 connection.
The router in the fan-free metal housing guarantees long-term reliability in critical corporate applications and is ideal for
use as an access router in SMEs, branch offices and home offices. In addition to the integrated ADSL 2+ modem, the
device has five Gigabit Ethernet ports, which can be configured for LAN, WAN or DMZ, and comes with a licence for
five hardware-accelerated IPSec tunnels. The built-in ISDN BRI interface and the UMTS USB modem connected to the
USB port can be used as a remote configuration access and as an ISDN backup interface.

The bintec RS232bw also has a dual band WLAN module with 2.4 and 5 GHz, which supports IEEE 802.11n. The new
802.11n technology permits gross transmission speeds of up to 300 Mbps and offers a better range than the previous
802.11g technology.
Thanks to the integrated IEEE 802.11n compatibility mode, the bintec RS232bw is compatible with all IEEE 802.11g
and IEEE 802.11abgh clients and supports the mixed operation of IEEE 802.11n clients and IEEE 802.11b/g or IEEE
802.11a/h clients. This enables the seamless exchange of existing WLAN routers through the bintec RS232bw without
significant changes to the infrastructure. Clients that already support 802.11n benefit automatically from the higher data
throughput.

Using functions flexibly
Only a few functions are required to forward data packets between two networks. The bintec RS232bw has features
that go far beyond just routing and allow it to be integrated into complex IT infrastructures. By using Extended Routing
and NAT (ERN) the data can be routed in IP routing according to criteria such as IP protocols (Layer 4), source or
destination IP address, source or destination port, TOS/DSCP, source or destination interface and the status of the
destination interface. In addition, you can also use network address translation to translate the data traffic for both
inbound and outbound connections and individually for each interface based on a wide range of criteria.
The comprehensive multicast support makes the device ideal for use in multimedia and streaming applications.
The Stateful Inspection Firewall (SIF) offers effective protection against attacks from the Internet through dynamic
packet filtering. Firewall handling is made easier through numerous pre-configured services. An optional content filter
rounds off the security functions of the devices*. In this case, all the outgoing Internet enquiries are classified and allow
contents not wanted to be reliably filtered out.
The basic equipment of the RS Series also offers a SIP application level gateway (ALG) for the direct connection of IP
telephones in the network or for registering with a VoIP provider, without affecting the security of the WAN connection.
The corresponding releases in NAT and the internal Stateful Inspection Firewall are controlled automatically by ALG for
the length of the communication.
Quality of Service is more than a watchword in FEC devices. Thanks to the rising convergence between voice and data,
the classification of data streams is gaining in importance. Our routers provide corresponding QoS mechanisms for
prioritising the VoIP traffic ahead of normal internet traffic, for example, and to guarantee it sufficient bandwidth.
Alternatively you can give normal data traffic priority over e-mail traffic. The bintec QoS implementation allows voice
data to be processed before e-mal data, for example, within a VPN tunnel.
The DNS proxy function supports the LAN for address implementation and the automated IP configuration of PCs is
carried out over an integrated DHCP server.
Remote CAPI is available for the joint use of various ISDN services.

Comprehensive IPSec implementation
The IPSec implementation integrated in bintec RS232bw works not only with preshared keys but also with certificates.
This allows a public key infrastructure to be created for maximum security. (The German Federal Office for Information
Security also recommends the use of certificates.)
Furthermore, the bintec IPSec implementation offers support when creating VPN connections with dynamic IP
addresses: Even small branch offices can be reached without having to be permanently online. If both VPN nodes only
have dynamic IP addresses, confidential information can continue. The exchange of IP addresses is carried out either
over dynamic DNS providers or directly over ISDN. The actual dynamic IP address is transferred either in the ISDN
D-channel (free of charge) or, if this is not possible, in the ISDN B-channel (at cost).
