Re: Cisco 3845 question

i think you're misreading the info.
it states that the 3845 will support full rate ds-3 with services and that
it supports a maximum of 2 ds-3's. they are two different things.
basically, it is not stating that it will support 90mb at line rate with
services. will it support 2 ds-3's, yes. does it support 1 ds-3 at line
rate with services, yes. but it won't support 90mb with services.

i'd never put more than a ds-3 wtih vpn, qos, etc. on a 3845..
