System Module interfaces

5 System Module interfacesThe System Module is equipped with the following interfaces:

Front panel connectors DC input connector (in the centre of the module)

The System Module FSMF has 14 connectors on the module. The connectors, their

types and purposes are listed in the table below.

Connector Type Description

DC Out FCI Power profile Power output for power chaining to one optional

baseband capacity extension sub-module.

DC In FCI Power profile Power input connector for power distribution to

the System Module.

LMPSite Support Interface

RJ45 Ethernet interface for Element Manager or SiteSupport equipment (battery backup module, for

example).

EIF2/RF/EXT6 SFP An additional optical interface that provides

RP3-01 (OBSAI) or CPRI interfacing to RF

Module or RRH.

Another option is interfacing to another System

Module (RP3-01 only).

It can be alternatively SW configured as a GbE

interface for external transport.

RF/EXT1 SFP Optical interfaces provide RP3-01 (OBSAI) or

CPRI interfacing to RF Modules or RRHs.

Another option is interfacing to other System

Modules (RP3-01 only).

RF/EXT2 SFPRF/EXT3 SFP

SRIO SFP Interface in the core module (and one similar

interface in each optional extension sub-

modules) support high-speed chaining up to

nine System Modules per BTS.

BB EXT1 QSFP Interfaces for broadband interconnecting

between the core module and the optional

extension sub-modules.

All necessary signals are carried over a single

copper cable between the core module and the

sub-module.

BB EXT2 QSFP

EIF1 RJ45 100/1000 Base-T Gigabit Ethernet interface for

external transport, that is, interfacing towards

the RAN, or directly towards the CN (LTE).

EAC HDMI External Alarms and Controls (EAC) interface

provides six alarm signals and six SW controlla-

ble interfaces that can be assigned to support

either control or alarm signals.

Sync In HDMI HDMI-based input and output external synchro-

nization interfaces enable, for example, inter-

facing to GPS equipment.Sync Out HDMI
