UNIVERSAL to RS-449/V.36 DCE Cable

To connect a SuperStack II bridge/router to a V.36 DCE device, cable the UNIVERSAL connector using a V.36 adapter cable.

Figure 2-10 shows the pin assignments of the V.36 adapter cable.

When constructing your own V.36 adapter cables, the required cable type is equivalent to Belden part number 9835. Cable length is limited to CCITT standard V.11 Appendix I.2.
