Cisco 3660 and 3640 for WAN

For WAN,Can I use only cisco 3600 series,for example, Cisco 3660 for Central office and 3640 for remot officies? (I should use Leased line(64Kbps) and E1 Links from TDM Telco Services,E1 for Central office and 64Kbps line for remote office.) Or, I must use a better Cisco Router from 3660?

For E1 at Central, 3640 is sufficient. For 64k cirucits at remote ends, even smaller routers will work fine.

Thanks.

Another point to consider, would be how much port density you want at the Central Office. 3640 has 4 slots, 3660 has 6 slots. With a 3660, you have better options for expansion.
