Installing Main Distribution Frame Hardware - Avaya S8500 Manual

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.
See DEFINITY Communications System Generic 1 and Generic 3 Main Distribution Field Design, 555-
230-630, for more information.
