Basic Multipoint Installation Distances
Figure 230, Basic Multipoint with One Work Location,
on page 576 provides cabling information for
fanout of ISDN-BRI multipoint installations. In this illustration, the terminating resistor is located in the
satellite closet. All distances assume 24 AWG (#5) (0.5 mm
