Supported ISDN Protocols and Access Types

Overview of ISDN Standards
Protocol Router for ISDN in a number of companies, refer to the
NetWare MultiProtocol Router for ISDN Solutions Guide by AVM.
ISDN D Channel Protocols
This section covers ISDN specific protocols and ISDN access types
supported by the NetWare MultiProtocol Router for ISDN. A de-
tailed survey on the supported networking protocols is given in the
NetWare MultiProtocol Router 3.1 Rules of Thumb, pp. 4-7, and there-
fore not repeated here.
NetWare MultiProtocol Router for ISDN supports access from
terrestrial ISDN BRIs (Basic Rate Interface) and PRIs (Primary Rate
Interface) as well as access over GSM-based cellular networks from
remote nodes equipped with AVM´s Mobile ISDN-Controller M1
and a mobile phone. A number of ISDN D and B channel protocols
are supported. The ISDN protocols are software-implemented and
can be loaded as required; thus, future enhancements and protocol
changes can be effected through software without the need to re-
place ISDN hardware components. Additionally, NetWare MultiPro-
tocol Router for ISDN 3.1 can also be equipped with an AVM Mobile
ISDN-Controller M1 and a mobile phone for direct mobile-to-mobile
links over GSM-based cellular networks. In Germany, for example,
mobile-to-mobile links cost half as much as standard ISDN links.
An overview of the important ISDN standards and their position in
the OSI Reference Model is given in Table 1-1.
