You don't need the async stuff if you are jsut dialing in when the
normal
WAN goes down.
I enter the follwoing into the modem via hyperterm:
at&fs0=1&c1&h0&d2&r2&b1&m4&k0&n6&w, or
at&f0s0=1&b0&n6&u6&m4&k0&w, or
AT&FS0=1&C1&D3&B1&K1&M4&W
Depending on your modem type one of these will work. This string will
force
auto answer on as well.
I would also lower your speed to 9600 which is the default to ensure
that
you have no connectivity issues. Other than that your config looks like
the
one I use every day.

Subject: connect the modem to aux port (not a ccie question, but very
common in the real world)
hello group
it is a basic question but really confused me.
i am trying to connect a modem to aux port so we can maintain the router
by
dialing in through aux when troubleshooting. my configuration is as
follow:
interface Async1
ip address 192.168.10.1 255.255.255.0
encapsulation ppp
async dynamic routing
async mode dedicated
!
no ip classless
ip route 0.0.0.0 0.0.0.0 Async1
logging buffered
!
line con 0
exec-timeout 0 0
line aux 0
modem InOut
transport input all
rxspeed 38400
txspeed 38400
flowcontrol hardware
line vty 0 4
login
there are several things i am not sure:
1,do i have to configure async interface or just aux )
2,are there special configuration on modem such as turn on the
auto-answer
3, is the command " modem autoconfigure discovery" necessary ? if yes,
how
can i avoid it? ( the ios-12.2 in 1721 does not has this command.)
any guideline is appreciated
james
