Main distribution frame hardware installation

This section provides information on installing a main distribution frame (MDF) in an equipment room. It must be installed before connecting media gateways to it and before connecting it to the public switched telephone network (PSTN) outside the building and stations within the building.

SYSTIMAX 110-type hardware is used for the MDF. 110-type hardware is available in two basic types: the 110A and 110P. The 110A requires less wall space than the 110P. The 110P includes horizontal and vertical cable troughs for managing cross-connect cables. 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.

Figure 2: Example MDF connections (G650 Media Gateway) on page 18 shows a detailed example of the G600 Media Gateway cables connecting media gateways and satellite closets to the MDF. This figure shows the cross-connections for one example station circuit.
