Connection Connection
Operation in LAN, triggering via a-b port behind telephone system
A local Ethernet (LAN) establishes – e.g. by means of a router – a
connection with the Internet on request.
This type of connection is useful with a time/volume tariff.
In the event of an access from outside, e.g. via external PC, the user
interface of the browser initiates a trigger request by the directory
server to a specific phone number.
The trigger request from the directory server via the a-b input of the IP
central unit causes the IP central unit to establish a safe connection to
the Internet via LAN and router. As soon as the connection is
established, the IP central unit logs in with the directory server.
Important: The request from the directory server to the a-b port does
not establish a telephone connection so that there are no connection
charges. The IP central unit detects the „ringing" signal at the a-b
terminals. The calling number is not identified (CLI). For this reason,
each call on the connected line will be detected as a trigger signal.
IIf this is undesired, a separate MSN can be assigned to the telephone
system in an ISDN structure. In an analog structure, a separate
connection is necessary in this case.
