[gauravm]

i have a router having a Leased Line configured on its serial interface.i need to configure another serial interface with a analog modem and a PSTN line .

then the objective is to place that line as a backup link to the Primary Leased Line connectivity.

could anyone help me in the configuration .

Thanks in advance.

There are many ways to skin this particular cat. Here is a good doc to get you started. It may be advantageous to use your aux port for dial backup, and leave your unused serial for future leased line usage.
