Configuration using public lines
This example uses telephone and leased lines to remotely
connect the LANs.
Remote connection is achieved by connecting the bases
using telephone and leased lines.
Digital lines are advantageous over analog lines as they
can achieve faster data communications.
Whether to use pubic lines or leased lines depends on the
cost factor. When using ISDN, one line can be used to
simultaneously carry out data communication and
telephone communication.
The ends of the line are presumed to be Ethernet. There
are cheap routers that support ISDN.
In addition, for connecting to remote sites that do not
have a network established, a dialup router can be used.
When the remote DX100/200 or the PC accesses a
network at the office, the dialup router will automatically
dial up and connect to the public line. In this case, the
dialup router must be configured, but you can construct a
closed network using public lines.
