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.฀
