the D channel. An ISDN caller ID generally consists of an area code and
an MSN.

The 

password for the ISDN connection

 is an alternative to the use of

the ISDN caller ID. It is always used to authenticate callers that do not
send an ISDN caller ID. The exact same password must be entered on both
sides. It is used for calls in both directions.

The 

Shared  Secret

 is the central password for security within the VPN.

The exact same password has to be entered on both sides

Data compression increases the transfer speed of the connection at no
additional cost. This is completely unlike the bundling of two ISDN- chan-
nels with MLPPP (

Multi Link

 

PPP

): The transfer rate will be doubled but

there will also be additional telephone costs for two connections.

Settings for the TCP/IP router

In TCP/IP networks, addressing has a special significance. Please note that
two interconnected networks are logically separate from one another. Each
must therefore have its own network number (in our example, '10.0.1.x' and
'10.0.2.x'). These network numbers may not be identical. 

Unlike when accessing the Internet, all of the IP addresses in the involved net-
works are visible on the remote side when coupling networks, not just those
of the router. The computer with the IP address 10.0.2.10 in the branch office
