Introduction
The models Business LAN R800+ are fully-featured routers that therefore also can be
used in combination with the integrated firewall for providing secure Internet access to a
complete local network (LAN).
With the integrated VPN option enables the devices act as powerful Dynamic VPN gate-
ways for external offices or mobile users.
The devices offer each an ADSL connector and also an ISDN connector. The ISDN line
can be used as back-up for the DSL connection, for remote management of the router, as
basis for the office communication via LANCAPI or for establishing VPN connections to
remote sites with dynamic IP addresses.
By using the Voice over IP function, these devices can transfer voice data over broadband
Internet connections as well.
How does ADSL and ADSL 2+ work?
ADSL (Asymmetric Digital Subscriber Line) is currently the most common broadband
Internet connection technology. Standard and almost ubiquitous telephone lines (analog
or DSL) are the basis for DSL data transfer to the nearest telephone exchange. From here,
the data is passed directly on to the Internet over high-speed connections.
The asymmetric ADSL version of DSL was designed for applications in which the user
receives high volumes of data but only transmits relatively small volumes, e.g. for acces-
sing the world wide web (www). With an ADSL connection, a user can download at up to 8
Mbps (“downstream”) and upload at up to 800 Kbps (“upstream”). These maximum rates
can be reduced as required by the ADSL provider.
To satisfy the strongly increasing demand for higher bandwidths, the standards ADSL 2
and ADSL 2+ provider higher data rates as a basis for applications such as video strea-
ming or high-definition TV (HDTV) over the Internet. Depending on the Internet provider,
ADSL 2 devices support data rates of up to 12 Mbps, and ADSL 2+ devices support up to
24 Mbps. Handshake routines during connection establishment ensure that the stan-
dards ADSL, ADSL 2 and ADSL 2+ are intercompatible.
With ADSL, all traditional telephony applications (telephone, fax, answering machine,
PBX) can still be used without restrictions. So-called splitters make this possible. Splitters
are devices that separate the telephone line's “voice frequencies” from the “data frequen-
cies” and ensure that the signals are forwarded to the appropriate networks.
10 Introduction
A splitter is also used at the subscriber end to permit ADSL modems/routers and conven-
tional telephone equipment to be used at the same time. The ADSL/ADSL 2+ modem is
integrated directly in the device. It can be directly connected to the splitter with the supp-
lied cable.
ADSL can operate over modern ISDN telephone service as well as conventional analog
service (POTS – Plain Old Telephone Service). Both telephone systems use different tech-
nical specifiations.
A Business LAN R800+ device can only be used with ADSL-over-ISDN
service, as they are offered at all T-DSL accounts from the Deutsche
Telekom.
Which use does VPN offer?
A VPN (Virtual Private Network) can be used to set up cost-effective, public IP networks,
for example via the Internet.
