This chapter describes how to set up a connection to a remote host over
Integrated Services Digital Network (ISDN) using PPP.
ISDN is a set of services provided by telephone companies over public
telecommunication lines. Voice and data services are supported at speeds
greater than normal telephone line speeds, using multi-channel digital
telephone lines through specially-configured switches. The channel used for
voice and data is referred to as the B channel.
As a data service, ISDN can be used as the medium for a Wide Area Network
(WAN) or for a dedicated connection to the ISP. In either case, PPP should be
used to provide connectivity between systems.
The ISDN module supports only the SunISDN™ version 1.0.3 software, which
is available with the SunISDN hardware. Most of the configurations that are
possible using ISDN and PPP are supported. The compression and multi-point
links configurations are not supported. (If you need advanced configurations
for your site, you can unconfigure the Netra ISDN module and use the tools
provided by the SunISDN software instead.)
