4.6.5 Installing the xDDF-21 Patch Panel

The NPT-1020 only supports balanced E1s directly. For unbalanced E1s, install the xDDF-21 that provides
balanced-to-unbalanced conversion for 21 E1s. The number of xDDF-21 units to be installed with one
NPT-1020 unit is based on the number of PME1_21 modules (for the number of unbalanced E1s required).
To install an xDDF-21 patch panel:
1. Route the 100-pin SCSI cables leading from the E1 interfaces on the PME1_21 panel along the side of
the rack to the location where the xDDF-21 patch panel is to be installed.
2. Before you install the patch panel, connect the SCSI cables leading to the rear of the xDDF-21 patch
panel. The cables are marked J1 and J2 and must be connected to their respective connectors.
3. Attach the patch panel to the rack rails and secure using the four supplied screws, washers, and nuts.
4. Connect the traffic cables to the front of the xDDF-21 patch panel, and make a note of the
appropriate channels on the identification label on the inside of the panel door.

4.6.6 Installing SM_10E/EM_10E ICPs

Three types of ICPs were developed to simplify installation and connection to customer termination
equipment. The ICP is connected to the SM_10E/EM_10E module using a special cable that spreads the
condensed cable to connector types commonly used for each service. Each ICP can serve one
SM_10E/EM_10E traffic module. An ICP can be installed anywhere in the rack.
