INTRODUCTION TO ERICSSON
MINI LINK CRAFT
Overview:
The Ericsson MW Indoor comprises of the
following:
Radio Transmission Cabinet (RTC)
AMM (Access Module Magazine)
The RTC is the cabinet where the Ericsson
equipment are been installed. Within it you have
the AMM and other equipment like the SAU e.t.c
Access Module Magazine (AMM)
The AMM is like empty mini equipment which in it
can accommodate various Modules. The indoor
plug-in units are installed in an AMM. The AMM
can be fitted directly into a 19” or metric rack. It
provides the mechanical housing and
interconnection for the plug-in unit’s through the
backplane. It has different slots according to
design specification. There are like three (3)
Design Specifications for AMM:
• 2p Magazine
• 6p Magazine
• 20p Magazine
• Each specification is according to the number of
MMU cards/ Site Design.
• 2p Magazine
• 6p Magazine
AMM 2p
The AMM2p has two half-height slots, one
equipped with NPU3, NPU3B, or NPU3C,
the remaining half-height slot can be
equipped with LTU, ETU, SAU or SXU.
The power supply is not included in NPU3,
NPU3B, or NPU3C; it is separately
integrated in the AMM on the left hand
side. At the Right Hand Side are slots for
Two (2) MMU’s. The AMM Kit delivery
comprises:
• One assembled AMM 2p
• One Rack Screw Kit
• One Earthen Cable, 1m
• One NPU3, or One NPU3B, or One
NPU3C.
• One RMM
• Two MMU
Note: AMM2p requires a DC cable
RPM517560/nnnn which must be
purchased separately.
AMM 6p
AMM 6p C or D have four (D) or five(C) fullheight horizontal slots, four (D) or two(C)
half-height horizontal slots and two halfheight vertical slots. They house one NPU3,
NPU3B, or NPU3C, one or two PFU3B, and
one FAU2.
The remaining slots in AMM6pC/D can be
equipped with MMU, LTU, SAU, AAU, SXU,
SMU or ETU. An AMM6pC/D Kit delivery
comprises:
• One assembled AMM6pC or one assembled
AMM6pD
• One Rack Screw Kit
• One Earthling Cable, 1m
• OneNPU3, or One NPU3B, or One NPU3C
• One RMM
• One DC Connector Kit
• One FAU2
• One PFU3B, (one additional PFU3B Kit is
needed for redundancy)
AMM 20p
The AMM20p has twenty full size slots of which 10 are available as
standard. Additional slots can be made available by ordering the
optional feature “AMM20p Slot Extension”. The NPU1B or NPU1C
occupies one slot. One or two PFU1 are fitted in dedicated slots at
the left hand side of the AMM. The AMM20pB -10R4 Kit delivery
with 10 available slots comprises:
• One assembled AMM20p
• Two Rack Screw Kits
• One DC Connector Kit
• One Earthing Cable, 1m
• One NPU1B, or One NPU1C
• One RMM
• One Cable Shelf, an additional cable shelf can be used when routing
many cables.
• One PFU1, one additional PFU1 Kit is needed for redundancy
• One Fan Alarm Cable
Note: Power Input for all magazines is -48v, this tells in the breaker
each power cable should be terminated.
The Node Processor Unit (NPU)
An NPU provides the main control system functions and holds a Removable Memory Module (RMM) for
storage of license and configuration information. In addition to this, it provides some traffic
handling functions and interfaces, but which ones are depending on type of NPU. The different
types are:
• NPU1 B: used for AMM 20p B provides user I/O interfaces, eight unstructured E1 interfaces, an
Ethernet interface for Site LAN, and a USB port for local management.
• NPU1 C: used for AMM 20p B provides User I/O interfaces, eight unstructured E1 interfaces, one
combined Ethernet Site LAN/traffic interface and one Ethernet Traffic interface, two Ethernet SFP
interfaces, and a USB port for local management. It contains a non-blocking gigabit Ethernet switch.
The switch is a managed VLAN switch (IEEE 802.1Q and IEEE 802.1D) and HW prepared for Provider
Bridge switching (IEEE 802.1ad).
• NPU3: for AMM 2p, 6p C, and 6p D, provides four unstructured E1 interfaces, one Ethernet Site LAN
and one Ethernet Traffic interfaces, two User Outputs, and one USB port for local management.
• NPU3 B: Provides four Unstructured E1 interfaces, one combined Ethernet Site LAN/traffic interface
and one Ethernet Traffic interface, two User outputs, and one USB port for local management. It
contains a non-blocking gigabit Ethernet switch. The switch is a managed VLAN switch and HW
prepared for provider bridge switching.
• NPU3 C: Provides four unstructured E1 interfaces, one combined Ethernet Site LAN/traffic interface
and one Ethernet Traffic interfaces, two User Outputs, and one USB Port local management. It
contains a non-blocking gigabit Ethernet switch. The switch is a managed VLAN switch and HW
prepared for provider bridge switching. The NPU3 C supports Synchronous Ethernet.
Modem Unit (MMU)
• The MMU is the indoor interface with the
radio unit. One MMU is required per radio
unit.
Note: Before you slot in your MMU, make sure
you have Connected your IF cable properly.
Radio Unit (RAU)
Overview
The basic function of the Radio Unit (RAU) is to generate and receive the RF
signal and convert it to/from the signal format in the radio cable, connecting the
RAU and the MMU. It can be combined with a wide range of antennas in
integrated or separate installation. The RAU connects to the antenna at the
waveguide interface. Disconnection and replacement of the RAU can be done
without affecting the antenna alignment.
DC power to the RAU is supplied from the MMU through the radio cable.
The RAU is a weatherproof box painted light gray, with a handle for lifting and
hoisting. There are also two hooks and catches to guide it for easier handling,
when fitting to or removing from an integrated antenna. It comprises a cover,
vertical frame, microwave sub-unit, control circuit board and filter unit.
The RAU is independent of traffic capacity. The operating frequency is
determined by the RAU only and is set on site using the LCT. Frequency channel
arrangements are available according to ITU-R and ETSI recommendations.
For detailed information on frequency versions, see the
Product Catalog
and
MINI-LINK TN ETSI Product Specification
.
Two types of mechanical design exist, RAU1 and RAU2.
