RAS access by the OpenCom 130 in a
LAN with an IP server
The user account administered by
the OpenCom 130, with which dial-
ling in is permitted, only allows the
establishment of connections using
TCP/IP. If you want to allow file or
printer access in the network, you

LAN-to-LAN Link

You can use the OpenCom 130 to in-
terlink two LANs via ISDN. To do this,
you configure two OpenCom 130
systems so that they can dial in to
each other. In order for this to work,
the two LANs must be configured for
different IP address ranges (subnet-
works). For at least one of the
OpenCom 130 systems, change the
prescribed address range for the
LAN.
In the Configurator, NET Configura-
tion: LAN-LAN menu you can con-
figure the dial-in settings. The

must set up a suitable user account
on the server for network log-in. If
you use the same log-in name for
the OpenCom 130 user account and
the same password for the network
log-in, you have to enter this combi-
nation only once when dialling in.
Note: In a larger Windows network
with several segments, the lists of
computer names visible in the net-
work environment can no longer be
established by broadcasts. In this case
you use a special WINS server whose
address the OpenCom 130 does not
make known to the workstation
when dialling in. For this reason, you
enter the address of a WINS server
manually in the network settings of
the workstation.
OpenCom 130 will set up a
connection whenever a TCP/IP data
transfer to the other LAN is re-
quested.
Note that such a connection is only
set up when specific requests are
made. These can be for FTP file
transfers, e-mails or downloading
Web pages. Name resolution via
broadcasts is not possible. If you
wish to use the LAN-to-LAN link to
access files and printers in the Win-
dows network, you need an IP-ena-
bled server that administers the
