Interface types supported are V.35, RS-449, EIA-530, X.21 with one clock source, and X.21 with two clock sources. The cable configurations for these interfaces are shown in
Figures B-1 through B-5. Only the pins which are connected to the probe are shown. Pins which go straight through, connecting DTE to DCE, are not shown.
