what is the difference between VIC-2FXS and VIC-2FXO?

Can them just be used in WIC slots of cisco 2600?

thanks in advance

The difference between them is, one provides Dial tone (FXS) and one requires Dial tone (FXO).

In the simplest sense you connect a "regular phone" to the FXS card and a "phone line" to the FXO card.

To use them in the 2600 you need an NM-2V or NM-1V

The VIC-2FXS is a station device and can provide loopstart and ground start service to a analog phone device. It will give you dialtone.

The VIC-2FXO is a office card. IT is meant to provide a telco office type conenction. This is used to forward digits out to telphony networks. It will not give you dialtone. They cannot be used in a WIC slot of 2600, they can be used in a VIC slot. The 2600 would require a NM-2V, or NM-1V in order for these modules to work properly.
