Authentication
For PPP connections, the dial-in user is authenticated by a user ID and password
(PAP/CHAP standards). This information, entered in the configuration of a Dial-
Up Networking connection, is transmitted automatically to the remote dial-up
server upon connection. More user information generally is not required.

Up Networking connection, is transmitted automatically to the remote dial-up

Some Internet providers (including many universities, etc.) use the calling line
identification transmitted over the ISDN D channel in addition to or instead of the
user name and password. The next section explains how the virtual modem must
be configured to transmit the ISDN D-channel number.

ISDN D channel
Note:
The ISDN D-channel number can be transmitted only if you did not
expressly request that your network provider deactivate transmission of
this number.
expressly request that your network provider deactivate transmission of
this number.
Entering the ISDN D-channel number:
Using the registry command
S49=<multiple subscriber number>
any multiple subscriber number (MSN)
from the block assigned can be specified for transmission in the D channel. The
block of numbers for your line is assigned by the network provider.
An invalid number entry is automatically replaced with the first MSN in the
assigned block.
block of numbers for your line is assigned by the network provider.
An invalid number entry is automatically replaced with the first MSN in the
assigned block.
If no number is set in register "S49", the first subscriber number assigned to your
DSS1 (Euro ISDN) line is sent.
DSS1 (Euro ISDN) line is sent.
Suppressing caller ID display (CLIR):
Use the registry command "S54=1" to
suppress the display of the ISDN D-channel number. This allows anonymity for
ISDN connections, for instance, in Dial-Up Networking. At a number of ISDN
connections, the ISDN feature ”Case-by-case suppression of Caller ID (CLIR)”
must be explicitly requested. The network provider generally activates this
feature free of charge.

If your ISDN-Controller is connected to an internal S0 access "behind" an ISDN
telecommunication system (internal S0 bus), some ISDN telecommunications
systems require that the connected device signal an MSN when the connection is
established (please see also the documentation of your ISDN telecommunication
system). In cases where caller ID of the outgoing MSN is to be suppressed at the
remote site enter the registry ATS49=<MSN>; S54=1

Summary of charge information:
To record the on-line charges accrued, specify
an MSN for outgoing calls to which all charges then will be billed.
For ISDN PBX systems with an internal S0 bus, the on-line charges for the
specified MSN can be calculated using the telecommunication system’s software.
