Purpose
Enter enable mode (also called
privileged EXEC mode).
Enter the password.
You have entered enable mode when the
prompt changes to .
5300#
Enter global configuration mode. You
have entered global configuration mode
when the prompt changes to
5300(config)#.
Enter serial interface configuration
mode. After configuring the controller, a
corresponding D channel serial interface
is created instantly. For example, serial
interface 0:23 is the D channel for
controller 0. You must configure each
serial interface to receive incoming and
send outgoing modem signaling.
Assign an IP address and subnet mask to
the interface.
Configure all incoming voice calls to go
to the modems.
Assign serial interface to dialer group 1.
The dialer group number is used with the
dialer-list command to determine which
packets will be meet the criteria
specified by the dialer-list command and
activate the ISDN connection.
Changes the default to encapsulation ppp
so you can enter ppp commands.
1
Enable PPP multilink on the serial
interface.
2 3
Enable CHAP and PAP authentication
on the serial interface.
Support dial-in PC clients.
Return to enable mode.
