Operation Manual

Configuring ISDN Call Destinations 121
- ISDN subscriber Number of the ISDN adapter/device in the
remote router or PC (including PBX Extension, if it is con-
nected to a PBX).
Entering the numbers here might be compared with dialing a number
on the phone: if one digit is wrong you will get a wrong connection or no
connection at all. Therefore make sure that you have the correct
number of the remote site and that you enter it correctly.
For special connection types such as semipermanent and 56
Kbps connections, refer to Chapter 13, section "Special Connec-
tion Types" in this Guide.
9. Check the Encapsulation Protocol .
Default: AVM Proprietary
Options: AVM Proprietary, PPP over ISDN
The AVM Proprietary and PPP over ISDN protocols are different
encapsulating methods for transferring network protocols over
the ISDN B channel.
AVM´s market-proven proprietary protocol has been in practical
use for more than four years. It is based on X.75SLP, which is
standardized in ISDN. Since it offers more powerful features
than PPP over ISDN such as data compression (according to
V.42bis) and various line management features, it is the recom-
mended protocol to be used for connections between AVM´s
NetWare MultiProtocol Routers for ISDN and NetWare Multi-
Protocol Router for ISDN and AVM´s remote node product
NetWAYS/ISDN. Both have been on the market since 1992 and
support channel bundling and compression according to V.42bis.
PPP over ISDN has been an international standard since 1994
and is intended to provide interoperability between remote
access products of different manufacturers over ISDN. Channel
bundling (PPP MP), for example, has been defined in 1995.
PPP over ISDN is not supported with the GSM protocol stack.
10. Specify the Subaddress .
The Subaddress is a supplement to the number that is dialed to
reach the ISDN-Controller configured at the remote site, and
specifies the concrete address of its logical interface. The Subad-
dress is not used for PPP connections.
