Cable Running to MDF
1. Cable Running to MDF
(1) Usually a pre-wired MDF is provided ex-factory for new installations. In this case, 50-wire ribbon cables are
used between the PABX and the MDF, as shown in NAP-200-003.
(2) In order to facilitate the termination of standard 25-pair cables which are shown in Figure 006-2 from the
system to an existing MDF, the length of each cable to be used should be determined according to the distance
between the MDF and the system, and each cable should be labelled at both ends using cable number or cable
designation as shown in Table 006-1.
Note
: Only centre-loaded CHAMP connectors (as illustrated) are suitable for use with existing 25-pair cables.
