2nd link is my conversation, 4 mounth ago and I absolutely forget it. Genius!

1st link I have just read it some days ago but i don't understand cisco P/N, but I think that it dosn't exist cisco cable with this pin-out. I think that is custom cable for test and laboratory and I can't find code.

Anyway, cod 2626x and 6026x is not true code to get this type of cable.

Hi,

You can use two cables, DTE on one side and DCE on the opposite one and connect these cables together. Your choice is V.35, RS-232, X.21,RS-449, RS-530 interface.

E.g.: When choosing the RS-232 interface you connect either the cable CAB-SS-232MT at the WIC-2T and at the same time the cable CAB−232FC at the WIC-1T or connect the cable CAB-SS-232FC at the WIC-2T and the cable CAB−232MT at the WIC-1T.

When configuring please do not forget to include "clock rate" command at the DCE side.

And YES, feel free to connect the second WIC-2T port to another router.

Best regards,
