IP pooling for dial-up access
With a greater number of available B channels,
ELSA LANCOM Business is an ideal
remote-access server for small and mid-size businesses. The router has a pool of IP
addresses from which an IP address is assigned to the LAN for the duration of the
connection so that a separate route does not have to be set for every dial-up access.
The settings for the IP address pool in
ELSA LANconfig in the 'TCP-IP' configuration
section on the 'Addresses' tab or under
/Setup/IP-router-module
for telnet or
terminal connections.
Office communications and LANCAPI
LANCAPI from ELSA is a special version of the popular CAPI interface. CAPI (Common
ISDN Application Programming Interface) establishes the connection between ISDN
adapters and communications programs. For their part, these programs provide the
computers with office communications functions such as a fax machine or answering
machine.
This chapter briefly introduces you to LANCAPI and the accompanying application
programs for office communications as well as providing you with instructions that are
important for installing the individual components.
ELSA LANCAPI
What are the advantages of LANCAPI?
Above all, the use of
LANCAPI offers you economic advantages. LANCAPI provides all
workstations integrated in the LAN (local-area network) with unlimited access to office
communications functions such as fax machines, answering machines, online banking
and EuroFileTransfer. All functions are supplied via the network without the necessity of
additional hardware at each individual workstation, thus eliminating the costs of
equipping the workstations with ISDN adapters or modems. All you need do is install the
office communications software on the individual workstations.
For example, faxes are sent by simulating an ISDN fax machine at the workstation. The
PC uses
LANCAPI to transfer the fax across the network to a ELSA LANCOM Business,
which establishes the connection to the recipient via ISDN.
LANCAPI’s dynamic design also means that communications paths are easily scaled.
When more B channels are needed to handle a larger number of jobs, another
ELSA
LANCOM Business is simply installed in the network. All devices present in the local
network then share the pending tasks.
