Figure 6. Autotest Connections for Twisted Pair
Network Cabling
Connecting to Star Topologies
Telephone cables wired in a star topology (Figure 7) are
connected together at a bridge tap at the distribution
center. The bridge tap connects each wire to all other
wires of the same number.
The tester detects bridge taps and measures the distance
to the bridge tap. To measure the length of each cable
connected to the bridge tap, you must connect the
wiremap adapter or remote ID locator to the bridge tap
and the tester to the wall outlet. The tester cannot
measure length past the bridge tap because reflections
from the bridge tap connections interfere with
measurements.
If you connect the tester to the bridge tap, the tester
measures the length only to the bridge tap, which is only
the patch cord length.
