8.1.3 General PPP Settings
Authentication You must enter the
➤➤
PPP settings for each WAN partner, e.g. the settings
needed for authentication of connection partners with
➤➤
CHAP or
➤➤
PAP (see chapter 7.3, page 159 ). If a call is received, X4000 then
recognizes the calling WAN partner from the calling party number with the aid
of
➤➤
CLID (Calling Line Identification) and therefore knows what
authentication negotiations it has agreed with this partner. The call is accepted
if the authentication is correct.
CLID In some cases, it is not possible to identify an incoming call via CLID. This is the
case, for example,
■
if the call is made over an analog line (the caller dials into your router via a
➤➤
modem ),
■
if the caller suppresses the CLID facility.
In both cases, X4000 receives no calling line number. The caller therefore
cannot be identified by CLID, even if the caller is entered as a WAN partner.
X4000 does not know which
➤➤
PPP authentication protocol to use to
identify the incoming call.
General
PPP settings
In order to answer the call in spite of the identification problem, X4000 executes
the defined general PPP authentication protocol with the caller. This protocol
does not refer to a certain WAN partner. If the data (password, partner PPP ID)
obtained by executing the authentication protocol are the same as the data of
an entered WAN partner, X4000 accepts the incoming call.
When you carry out remote CAPI configuration on the hosts, you must enter
the user name and password for each user corresponding to the entries in
X4000 .
