Installing the Avaya S8700 Media Server with an Avaya G650 Media Gateway
December 2003
Installing main distribution frame hardware
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.
NOTE:
If standard 110A cross-connect equipment is used, consult DEFINITY Communications
System Generic 1 and Generic 3 Main Distribution Field Design (555-230-630).
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.
See DEFINITY Communications System Generic 1 and Generic 3 Main Distribution Field Design, 555-
230-630, for more information.
Figure 43, Example MDF connections (MCC1 Media Gateway),
on page 138 shows the cross-
connections for common circuit packs. See this figure when cross-connecting wire pairs to the MDF.

Figure 44, Example MDF connections (G650 Media Gateway),
on page 139 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.
