OTE: The cable route described above assumes that the E1 module is installed on the left
side in the NPT-1020. If it is installed on the right side, perform the same procedural steps but
on the cabinet's right side.
5. Use cable ties as required to fasten the cables to the cable guide and to the cable clamp.
6. Use a cabling diagram of the cabinet (or site) to associate module connectors with the appropriate
DDF connections. Cut excess cable length if necessary.
7. If the DDF is installed in the frame, see
to the DDF wiring blocks.

5.10.5 Routing and Connecting Coaxial Cables

Individual coaxial cables are used to connect to the interfaces located on E3/DS-3 and electrical STM-1
modules.
As part of site preparations, suitable cables must be routed from the relevant High Rate DDF (if used) to the
intended cabinet location and connected to the coaxial cables with DIN 1.0/2.3 connectors. Leave sufficient
length to permit routing the cables to the appropriate level in the cabinet.
To connect coaxial traffic cables to E3/DS-3 or STM-1 modules:
1. Pull each coaxial cable to the level of the corresponding electrical connection module.
2. Connect the DIN 1.0/2.3 connector on the cable to the corresponding connector on the module.
3. Based on the cabinet (or site) cabling diagram, arrange the coaxial cables in groups according to the
designated module and route them along the left side of the cabinet.
4. Bend the cables and thread them through the left side cable guide of the cabinet.
5. Route the cables near the left cable clamp on the C-rail.
