RAS Access
You can establish a connection from an external computer with an ISDN card to the OpenCom 100. The necessary TCP/IP settings are transmitted by the OpenCom 100 on establishment of the connection. The computer that has dialled in now has access to all services in the LAN capable of being used via TCP/IP. The authorisation for RAS access is set up in the Configurator via the User
Manager: User Groups menu.
In a serverless LAN, Windows uses the NetBIOS protocol for accessing files and printers via the network environment. NetBIOS can use Net-
BEUI, IPX/SPX or TCP/IP as the transport protocol. In the network environment, you can only access files and printers on workstations using TCP/IP for NetBIOS.
Note: In a serverless LAN, the work-
stations running decide independently which one is to keep the list of names visible in the network environment. This process is triggered by broadcasts, which can take some time on a RAS connection. You can shorten this period by activating the “Find >
Computer” function in the Start menu and selecting the client computer.
OpenCom 100 in a LAN with an IP-enabled Server
In a LAN with an IP-enabled server, you should coordinate integration of the OpenCom 100 with the responsible network administrator. You must decide on the IP address space to be used and which network services
(DHCP, DNS, RAS, Internet access) the OpenCom 100 is to handle in the
LAN.
