Hello Joseph,

if you want to implement an out of band management for emergency to be used only when needed you need to use dial on demand routing.

you can find the basis of DDR in 12.4 dial config guide

http://www.cisco.com/en/US/docs/ios/dial/configuration/guide/dia_preparing_ddr_ps6350_TSD_Products_Configuration_Guide_Chapter.html

for the WIC-1AM-V2 it has a built-in analog POTS modem

follow the following document

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/gt12pwi8.html#wp1053415

as you can see from router point of view it is seen as an interface Asynch.

you will use a separate address plan for out of band management so that the device can be reached = called or it can call the NOC center

a floating static route completes this scenario using PPP authentication and call screening (specifying the calling number that can be accepted)

Hope to help

Giuseppe
