Notes to the individual values:
User name and password: Users authenticate themselves with this
information when dialling in.
Incoming number: The LANCOM router uses the optional ISDN caller ID
as an additional user authentication. This security function should not be
used when users dial in from differing locations.
The ISDN calling line identity (CLI)
The ISDN caller ID—also known as CLI (Calling Line Identity)—this is the telephone number
of the caller which is transmitted to the participant receiving the call. As a rule, it consists of
the country and area codes and an MSN.
The CLI is well-suited for authentication purposes for two reasons: it is very difficult to manip-
ulate, and the number is transferred free of charge via the ISDN control channel (D-channel).
