To connect individual coaxial traffic cables to the NPT-1020 or xDDF-21:
1.
Based on the site cabling diagram, arrange the coaxial cables in groups according to the designated
electrical interfaces and route them along the guides at the side of the rack to the appropriate
NPT-1020 or xDDF-21 unit.
2.
Cut excess cable length, if necessary.
3.
Connect the NPT-1020 or xDDF-21 end of the cables to DIN 1.0/2.3 connectors and the other end to
the relevant coaxial cable connector, crimping the cable as required.
4.
Bend the cable and thread it through the side cable guides of the rack so that the cable connector is
positioned at the level of the appropriate adapter. Use cable ties as required to fasten the cable to
the rack side rails.
5.
Connect the connector on the cable to the corresponding electrical connector on the NPT-1020 or
xDDF-21.
6.
Connect the connector on the other end of cable to the corresponding electrical connector on the
external DDF.

Routing and Connecting Data Interface Cables to
Ethernet Interfaces
Data cables with RJ-45 connectors are used for connecting FE interfaces on data modules and on the
NPT-1020platform.
As part of the site preparations, Category 5 or better cables must be routed from the relevant Ethernet DDF
(if used) to the intended rack location and connected to the RJ-45 connectors. Sufficient length must be
available to permit routing the cables to the appropriate level in the rack.
To connect data cables to an Ethernet interface:
1.
Based on the site cabling diagram, route the data cables along the guides at the side of the rack to the
appropriate NPT-1020 unit.
2.
Pull each data cable down to the level of the NPT-1020 unit.
3.
Bend the cable and thread it through the side cable guides of the rack so that the cable connector is
positioned at the level of the NPT-1020 unit. Use cable ties as required to fasten the cable to the rack
side rails.
4.
Connect the RJ-45 connector on the cable to the corresponding connector on the data module or
NPT-1020 front panel.
