Pin Assignments
Since FrameSaver SLV NNIs have standard connectors, there is no need to order, buy,
or make special cables. You can use any standard straight-through cable for each
interface. However, interface and cable pin assignments are available in Appendix G,
Cables, Connectors, and Pin Assignments, of the User’s Guide.
