connection for pins 11 and 27 of the plugin’s gold
finger card edge. Insert the grounding wire into the

3. CONNECTIONS
The barrier strip provides screw-down terminals for
network and customer signal interfaces. Customer-
side connections are usually made through the RJ-48
connector which is prewired to the barrier strip. To
connect to the barrier strip, conductors should be
placed beneath the square washer of each screw
terminal and tightened. Table 1 provides cable pair
connections and descriptions.
The T400 LP housing is compatible with other loop-
powered T400 units. Table 2 describes the terminal
barrier strip and circuit card gold finger connector
interface signal assignments.
