+ configuring the DDR interface. PPP
+ is configured on the dialer interface using the same commands that
+ enable PPP on a serial interface. HDLC is the default encapsulation for
+ an ISDN interface on a Cisco router, but most networks employ PPP for
+ circuit-switched connections. Because of its robustness,
+ interoperability, and additional features such as authentication, PPP is
+ the data link protocol in use on the B channels of most routers. To
+ configure PPP on the DDR interface use the following commands:

+ <p><font face="Courier New" size="2">Home(config)#<b>username

+ </blockquote>
