Optional LANCOM Dynamic VPN
With the LANCOM VPN Option a LANCOM DSL/I-1611 Office is enabled to
set up VPN tunnels even between two peers with both dynamic IP addresses.
This is enabled by the patent-pending
LANCOM Dynamic VPN technology.
LANCOM LANCAPI and LANCOM CAPI Faxmodem
The main advantages of using LANCAPI are economic ones: LANCAPI is a
special implementation of the CAPI 2.0 interface that permits different com-
munication programs to access a router via the network.
By
LANCAPI , all workstations that are part of a LAN get an unrestricted
access to office communication functions such as fax and eurofile transfer.
All functions are available via the network, without additional hardware at
the workstations. This eliminates the costs of equipping all individual work-
stations with ISDN adapters or modems. Solely the software for office com-
munication has to be installed at each workstation (if not already provided by
the operating system).
A fax device is simulated at the workstation so that faxes can be sent. With
LANCAPI , the PC forwards the fax via the network to the router, which estab-
lishes the connection to the recipient then.
Automatic time control
The device needs always the exact time in order to provide meaningful sta-
tistics and to choice the right connection via the least-cost-router . The device
itself can read the time via the ISDN network or via public NTP time servers.
The internal time of the router is compared either with each connection
establishment or with each switch-on of the device with the external time
service. A manual setting of the time is also possible, of course.
Channel bundling and compression
The device supports on the ISDN line both static and dynamic channel bun-
dling via MLPPP and BACP. Stac data compression (hi/fn) can be used to
achieve an additional increase of the data transfer rate up to 400%.
Least-cost-routing
Also with a considerable large number of providers for telecommunication
services, you always select the most inexpensive ISDN lines with the
least-cost-router. Thereby you define once the provider with the most favor-
able rates for your needs and by each connection, the router selects automat-
