To dial out on the ISDN and serial lines, you
can configure dial-on-demand or manual
dial. Dial-on-demand automatically dials the
destination bridge/router when network
traffic is present and hangs up when the
network is idle. Dial-on-demand also
provides failover support. If the primary line
goes down, the bridge/router will failover to
another available dial-up line, either from a
dial pool or from another path assigned to
the same port. To dial manually, use
NETBuilder commands to dial and hangup.
