NPT-1020 Installation and Maintenance Manual

3.4.2 Typical NPT-1020 Installation

For a typical installation of a NPT-1020 shelf in an ECI's ETSI rack, see
NPT-1020 in an 2200 ETSI
In addition to the NPT-1020 itself, the equipment installed in the rack includes:
One RAP installed at the top of the rack. The RAP is used to connect external power and alarm

monitoring lines (RAP-4B only) to the NPT-1020 shelves installed in the rack. The RAP fully supports
up to four shelves with dual power feeding or eight shelves with single power feeding. In addition to
the space needed for RAP installation, you must leave at least 50 mm of free space under the RAP for
cable routing.

OTE: The RAP-BG does not support alarm monitoring lines.
Fiber Storage Tray. A separate FST can be installed for each NPT-1020 with optical modules. Each FST

contains two storage reels, enabling the fiber to be stored on the right or left side of the tray. Leave at
least 50 mm of free space between the NPT-1020 shelf and its FST, and another 50 mm free between
the FST and the next NPT-1020 shelf.
xDDF-21. When unbalanced E1 interfaces are needed, the xDDF-21 should be installed with the

NPT-1020. Each xDDF-21 can support 21 channels of E1. The xDDF-21 can be installed anywhere on
the same rack on which the
NPT-1020 shelf is installed, or on another rack.
ICPs for the SM_10E/EM_10E, including ICP_VF, ICP_V24, ICP_V24F, ICP_V11_V24, and ICP_V35.

When PCM interfaces are provided by the SM_10E/EM_10E, the corresponding ICPs can be installed
in order to simplify installation and connection to customer termination equipment. Each ICP can
support one SM_10E/EM_10E traffic module. ICPs can be installed anywhere on the same rack on
which the NPT-1020 shelf is installed, or on another rack.
3.4.3 Integrating NPT-1020 Platforms and Other Equipment
in One Rack
When NPT-1020 platforms and associated accessories do not occupy the entire rack, additional equipment
can be installed in the remaining rack space. Make sure that any heat generated by this equipment can be
dissipated efficiently, and that thermal isolation is provided between the various equipment units.
In the event of additional equipment being installed in the rack, contact ECI's Customer Support team for
assistance.
