    Cisco Router as a PSTN Simulator

    Is it posible to emulate PSTN using Cisco routers.

    Im thinking 2x 1751-V both routers have FXS and FXO.

    Can i connect both router in FXO that 1 acts as Voice Gateway and 1 is PSTN simulator?

    Hi,
    Sure it will work for your CCNA-V lab simulator. And connect fxo to fxs or vise versa to make it working.
