I would configure a track to monitor the interface. You can't monitor a t1 interface directly with tracks, but you can monitor the routable interface that is connected to it (ppp, hdlc, frame-relay, etc.).
Example of track testing ppp 1:
test if interface ppp 1 line-protocol
Example of the mail client:
address to <recipient@address>
address from <from@address>
server <your smtp relay address>
subject WAN interface monitoring event
do show interface t1 0/1
do show interface ppp 1
capture trigger track wan1
send trigger track wan1 fail
This will email you whenever the ppp 1 interface goes down.
Im not sure if you have to create another mail-client and send trigger track wan1 pass to report on the interface going back up, or if you can issue a second send trigger within the same client, but this works.
Thank You! I will try it after hours.
