connecting a linux router to a cisco 1841 router

Hello, as a Cisco newbie I am thinking about building a linux router (for a study project) to connect to a Cisco network (2 x 1841 routers).

Can somone please tell me what kind (standard) of serial interface card will I need to install on the Linux PC router to enable serial communications with the other two 1841s.

Thanks for any advice.

You should ask that in a Linux forum.

Hello Philip,

Regarding the standard of a serial interface that could be installed to a Linux box and yet be capable of talking to your router: if you have a HWIC-2T or HWIC-2A/S serial module, it is compatible with the following serial standards:

EIA-232, EIA-449, V.35, and X.21 are supported in DTE or DCE mode, and EIA-530 and EIA-530A are supported in DTE mode.

Taken from http://www.cisco.com/en/US/prod/collateral/modules/ps5949/qa_c67-490366.html

Best regards,

Peter
