TIWAY 1 Ti505 NIM User Manual
With the cover removed from the PPX:500–5606 Tap Housing, note that there are three
sets of terminals, and that each set is labeled G (Ground), W (White), and B (Blue). (See
Figure 2Figure 2.) One set of these terminals is for the incoming Local Line twisted pair;
the center set is for the drop line; and the remaining set is used to connect the Local Line
to the following node, or to terminate the Local Line if the tap housing is the last one on
the network trunk.
For consistency in installation, always connect the LLM+ (Pin 6 of the Local Line Con-
nector) to the white strand of the twisted pair and to the terminal marked “W” in the tap
housing. Connect the blue strand to the LLM– (Pin 9 of the Local Line Connector) and to
the terminal marked “B” in the tap housing. The Cable Shield and Signal Common
should be connected to Pin 3 of the Local Line connector and to terminal “G” inside the
tap housing.
NOTE
All Siemens tap housings contain factory-installed termination
resistors. If the tap housing is not used to terminate the Local Line, the
terminating resistors must be removed when the output cable is
attached.
