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.
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.
