[nsp] ISDN redundant link.

[Temkin, David]

You can force it to dial by either pinging the other side of it's dialer map
(if you're using dialer maps) and watching a debug dial, debug ppp auth and
making sure that all works OK...  This obviously won't test to ensure that
the actual failover works, but that the other side answers the phone and is
configured correctly.

If you're not using dialer maps,  you can force a dial from the command
line, but that really proves absolutely nothing other than your ISDN line
works.  Use the "isdn call interface" command.
