Some our sites have this as ISDN is not available. Connect a modem to the aux port and then create an async interface on the router. It will act just as BRI plus a few configs that pertain to Async interface. The AUX port also has to be configured. HTH. Here's a sample:

(Global) chat-script dial "" "ATDT\T" TIMEOUT 120 CONNECT \p

interface Async65
 bandwidth 28800
 ip address XX.XX.XX.XX XX.XX.XX.XX
 no ip directed-broadcast
 encapsulation ppp
 no ip route-cache
 no ip mroute-cache
 shutdown
 dialer in-band
 dialer idle-timeout 600
 dialer map ip XX.XX.XX.XX name XX modem-script dial broadcast XXXXXXXXXXXXX
 dialer-group 1
 async default routing
 async mode dedicated
 fair-queue 64 32 0
 no cdp enable
 ppp authentication chap

line aux 0
 exec-timeout 0 0
 password 7 XXXXXXXXX
 autoselect ppp
 modem InOut
 transport input all
 stopbits 1
 speed 115200
 flowcontrol hardware

Subject: Telephone line back up?

Group,

I have come up with a situation where the primary circuit is not stable and
there is no ISDN service in the area but telephone lines. Is there any ways
to have telephone lines as a backup like ISDN backup?
I am not sure if this is doable and if so, how.

Thanks!

Yuki
