Main distribution frame labels
Figure 4: Label graphic symbols and nomenclature on page 20 shows the graphic symbols used on labels for the media gateways, cross-connections, information outlets, and cables. The labels are color-coded to identify media gateway wiring:
●Green — To central office (CO)
●Purple — To media gateway ports
●Yellow — To auxiliary equipment and miscellaneous media gateway leads
●Blue — To information outlets
●White — From MDF to satellite locations
Each label identifies two rows on the terminal block. The upper half identifies the row above it and the lower half identifies the row below it. The labels are inserted into the clear plastic designation strips furnished with the terminal blocks. The strip is snapped in place between the terminal block rows. Label code number 1220A (comcode 103970000) contains all of the required labels.
