I would like to know if the router can support 2MB. currently upgrading from 1MB to 2MB for cisco 1721 router. i am sure this can be done right?
Not need to upgrade to 1841 to cater to 2MB leased line right?
Yes, the 1721 can support a leased line of 2Mb on an E1 circuit, xDSL, Frame Relay or any WAN link that supports 2Mb.
Hope it helps!
