Media gateway connections to the MDF
38 Installing and Connecting the MDF and Telephones
●Coil the cable around the columns in the cable slack manager to store cable slack. The
first run should always go across the full length of the 5 columns in the cable slack
manager.
●Connect the cable to the assigned connecting/terminal block.
●Avoid placing copper cables where they may bend or strain fiber optic cables.
Trunk cables among network interface, sneak fuse panel, and media gateway The 1-pair of central office (CO) trunks are installed by the network provider in the green field.
Up to 24 pairs may be terminated on each row of the 110-type terminal block. Tie trunks also
appear in the green field with up to eight 3-pair trunks terminated on each row of the 110-type
terminal block.
WP-90929, List 1 and 3 concentrator cables can be used to connect the media gateway to the
110-type terminal blocks in the purple field. The 1-pair patch cords/jumper wires are then run
from the purple terminal block rows to the green terminal block rows in order to establish the
correct 3-pair modularity.
Installing cables between media gateway and MDF To install cables between the media gateway and the MDF:
1. Install D rings on the wall between the cable slack manager and the terminal/connecting
blocks mounted on the MDF.
2. Install a self-adhesive port label on the back of each connector on the connector cable.
Position the labels so the media gateway connector retainers do not cover them.
3. At the rear of the media gateway, connect one end of the connector cable to the assigned
connector.
4. Route the cable down the rear of the media gateway, through the cable slack manager, and
to the MDF.
5. At the MDF, connect the other end of the cable to the assigned terminal/ connecting block
connector.
6. Store the cable slack in the cable slack manager.
7. Repeat Steps 2 through 6 until all cables are installed.
