I've a task to develop topology for one central and multiple regions sites. The main task is to minimize DS0 timeslots, so I'm going to use hardware compression (taking into consideration that there would be 99% text-only not-compressed data through FTP).

I'm looking for Cisco3825 + Channelized 2xE1 NM + 2 AIM-COMPR4. But what can I use on central site? There is no HW compression modules for 7200 or even 7600 routers, so what output can I expect on that series in software/CPU? Or any other suggestions?

Thanks :-)
