May 2003
Install 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 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 Main Distribution Frame (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 m) and 15-foot (4.5 m)
lengths.
Refer to DEFINITY Communications System Generic 1 and Generic 3 Main Distribution Field
Design, 555-230-630, for more information.
