Cross-Connections to Distribution Frames and Building 91
Practice 450-1011-201
How to Terminate Building Wiring at the Cross-connect Panel
It is assumed that the pre-installation wiring contractor has already installed all
necessary building wiring and Teladapt jacks. The cross-connections should have
been made from the panel to the building wiring at the same time. However, if this
has not been done, proceed as follows:
(1) To locate the station location codes for the wires to be connected, see the floor
plan and the wiring log in the Site Records, 450-1011-152. These codes should
match the codes that the pre-installation wiring contractor marked on the
distribution frames. If no distribution frame is used, the codes should be tagged
on the ends of the cables themselves.
(2) Route the cables to the cross-connect panel and up the side of the panel via the
distribution rings.
Note: The cable should have 24-gauge twisted-pair wires. Typically, six-wire
(three-pair) cable is terminated at the distribution frame, but only four-wire
(two-pair) wiring is jumpered to the cross-connect panel as shown in Fig. 9-3.
(3) Connect the wires to the appropriate BIX connectors on the cross-connect panel.
These connectors cross connect to the 50-pin connectors at the top of the panel
as shown in Fig. 9-4.
