Cisco x.21 DTE to DCE back to back cables

[matthew_epps]

I cannot find a product reference code for an x.21 DTE to DCE back to back cable, can anyone help?

I want to avoid using separate cab-x.21MT and cab-x.21FC cables as the routers I want to join are co-located in the same rack.

Thanks,

Matt

Cisco do not make one but several manufactures do sell custom back to back cables. The following URL provides a part number for a back to back V.35 cable by Blackbox:

Many thanks for the information, I will try Blackbox.
