Accessories

The MINI-LINK TN R3 product program contains a comprehensive set of
accessories for installation and operation. This section gives additional
technical information for some accessories.
7.1

Interface Connection Field (ICF)

MINI-LINK TN R3 uses Sofix connectors for 120 Ω E1 traffic connections on the
plug-in units in the AMM. Sofix is a high-density connector holding four E1s per
connector. It is optimized to occupy minimal space on the plug-in unit fronts,
which enables very compact site solutions. D-sub connectors are used for
connection of power supply and User I/O.
The ATU uses RJ-45 connectors for E1 traffic.
For further details on connectors, see MINI-LINK TN ETSI Product Specification
and MINI-LINK TN ETSI Indoor Installation Manual.
Instead of connecting directly to the front of the units in the AMM, an Interface
Connection Field (ICF) can be used. It provides a panel with connectors
and pre-assembled cables to be connected to the units. The use of an ICF
enables easy on-site installation and flexibility, with a minimum of impact when
re-configuring traffic cables.
The following types of ICF are available:
ICF1
ICF2
ICF 16x2
ICF3
The ICF fits in standard 19" or metric racks.
The following figures show examples of the different ICF types and the number
of connectors for each type.

The ICF1 is used for AMM 20p. It provides connectors for E1 traffic
(D-sub 120 Ω or SMZ 75 Ω), redundant power supply of PFU1 and
FAU1, User I/O, and fuses for FAU1, see Figure 93 on page 124.
The ICF2 is used for AMM 6p B. It provides connectors for E1 traffic
(D-sub 120 Ω or SMZ 75 Ω) and User I/O, see Figure 94 on page 124.
The ICF 16x2 can be used for any AMM. It provides connectors for E1
traffic (D-sub 120 Ω or SMZ 75 Ω), see Figure 95 on page 125.
The ICF3 can be used for any AMM or ATU. It provides connectors
for E1 traffic (BNC 75 Ω). ICF3 has a modular design with a frame
with room for up to four connection boxes, each one with a specific
cable connecting to the plug-in unit (Sofix) or ATU (RJ-45), see Figure
96 on page 125.
