Cable Pinouts

This appendix shows the pin designations for the following:

Ethernet AUI

Table C-1 describes the pin designations for the Ethernet AUI interface.

WAN interfaces support V.35, RS-449, EIA-530, X.21 with one clock source cable pinouts, and X.21 with two clock source cable pinouts. The cable configurations for these interfaces are shown in Figure C-1 through Figure C-5. Only the pins which are connected to the SwitchProbe device are shown. Pins which go straight through, connecting DTE to DCE, are not shown.
