Cisco 1751 Router

[Guest_imported]

I am getting a Cisco 1751 Router for my company. This is my company layout. We share a floor with some other companies, this floor is setup with a T1 line, which most of the offices use for Internet access. This T1 line comes into a closet where it is connected to a Cisco Router, and from that router to a switch. We have a connection to that switch and a Static IP address. Here is the question, I know the 1751 router comes with one ethernet port; Do I need to get an extra ethernet port, that way I can have one connection to the main switch and from there another connection to my internal network?

Any help would be greatly appreciated.

Thanks.

1751 comes with FastEthernet port.
So all you need to do is configure trunk line on that router's FastEthernet interface and put a cisco switch that support trunk between your new router and the existing switch(Main Switch).

So the new configuration would be like this:

T1---CiscoRTR---MainSwitch-----------YourSwitch---YourLAN
