Anleitung Zusammenfassung
The media gateways are connected to the MDF with the supplied B25A male to female 25-pair cables. The cables are provided in 10-foot (3 meter) and 15-foot (4.5 meter) lengths. Figure 1: Example MDF connections (MCC1 Media Gateway) shows the cross-connections for common circuit packs. See this figure when cross-connecting wire pairs to the MDF.

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 (3-pair) 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. Figure 4: Label graphic symbols and nomenclature r758422i LJK 050996 Figure notes: 1.
