All-
I intend to setup a simple modem lab as follows:
To simulate the POTS phone lines, instead of using POTS line simulator like virtual console, can I use one 2811 router with VIC2-2FXS module, any configuration suggestions will be appreciated. Thanks for your input.
Solved! Go to Solution.

Alan,
Happy New Year.
All the best for 2013.
Yes, this should be OK.
I take it that your router has a DSP like
a PVDM2-8 to cater for the FXS ports.
2 FXS ports and dial peers.
