Installation
1. Disconnect the Line
At the NID (Network Interface Device) or first accessible entry point, disconnect the
customer premises wiring from the local loop.
!
WARNING:
Do not continue unless the line has been disconnected. Refer to
Important Safety Instructions, page 13.
2. Determine Wiring Arrangement
Use a tone generator or continuity tester to determine whether wall jacks are wired in a
series or star configuration.
H
If wall jacks are wired in series, trace the wiring and use the tone generator or
continuity tester to determine which is the first wall jack wired to the line’s
origination at the NID or other entry point. You must replace that wall jack with a
Wall Jack Filter.
H
If some or all wall jacks are wired in a star configuration (that is, more than one wall
jack is wired directly to the NID or other entry point), you must replace every such
wall jack.
Use the following table to select the proper procedures for installation.

* Replace the wall jack nearest the NID with a Wall Jack Filter. If the SuperLine IAD
will not be used at that location, treat the Wall Jack Filter as a NID and run new
(unfiltered) wiring for the SuperLine IAD from the filter input connections.
