WAN Accelerator

Hi,

I'm searching for a tutorial to find a WAN accelerator solution.
The network environment is CISCO and I also want to implement a CISCO
solution.
Are there any solution guides ?
I search the CISCO side but I can't find any good tutorials

The reason why I would like to implenent this, there are several
performance problems while working over WAN lines (T1) with MS office
product.

thanks
