I'd like to know what is necessary to configure the parameter line 1 60 in a Cisco 2821 router with a two E1's direct connected in a interfaca VWIC2-MFT-E1 and two PVDM's modules installed.
When I try to enter the line "router(config)#line 1 60" the ios returns an error message that there are no physical hardware to support "line 2". I just can enter line 1.
Which is necessary to do this?
My best Regards,
