38LS-SWITCHED OR SNBU-CABLE DIAGRAM
The 38LS-switched or SNBU-cable diagram and table
show the signal path from the communications MPU
card to the connector (J140) on the cable connector
panel. The table indicates probe points that can be
referenced by the MAPs. Use th is cable diagram for
switched networks for the SNBU section of a
nonswitched 38LS card (see 865 for nonswitched
probe points). See 901 for information on how to use
the cable diagrams. The arrow
(~)
indicates the
logical direction of the signal.
