This does not apply to the router.
Standard V.35 Straight-through Cable
A standard V.35 straight-through cable can be used to connect a DTE port to a
DTE, where a 34-pin plug-type connector is needed for the data port and a
34-position socket-type connector is needed for the DTE. No special-order cables
are required.
