5.4 LTE947: FSMF Flexi Multiradio 10 System ModuleIntroduction to the featureFlexi Multiradio BTS System Module FSMF is a highly integrated 3U high outdoor System Module of the Flexi Multiradio BTS. It hosts the telecom control, system opera-tion and maintenance, baseband application, transmission, and power distribution func-tionality. The System Module can be also equipped with optional capacity extension sub-modules which bring additional signal processing power and/or allow the system to support different radio access technology. Adding the capacity sub-modules in the field does not affect ongoing traffic.

The System Module can also act as a System Extension Module operating in a baseband extension mode. Flexi Multiradio BTS architecture supports chaining up to nine System Modules enabling to build very high capacity sites and different redundancy solutions.

Flexi Multiradio System Module hardware supports the following software operating modes:

GSM/EDGE mode WCDMA mode LTE in FDD and TDD mode

5.4.1 Benefits

Functional overviewThe Flexi Multiradio BTS System Module FSMF consists of a 3U high casing, which can accommodate in addition to the base module, optionally

up to two baseband sub-modules (FBBA), one additional transport sub-module (FTxx), one power distribution sub-module (FPFx).The following functions are integrated in the FSMF:

ethernet transport, clock and control functions, baseband processing, fan control, status LEDs.Table Flexi Multiradio System Module FSMF peak throughput shows the total through-put of a Flexi Multiradio System Module, which can vary depending on the combination of the modules used. Note that MIMO is supported for both HSPA and LTE.

One FSMF System Module provides a hardware baseband capacity for up to three 20 MHz LTE cells.

5.5 LTE949: FPFD Flexi Power Distribution Sub-moduleIntroduction to the featureThe FPFD is a highly integrated optional power distribution sub-module for the new Flexi Multiradio System Modules.

5.5.1 Benefits


Operator benefitsOutdoor Power distribution unit with fuses is integrated into the 3U high System Module casing. The FPFD is installed into the Flexi Multiradio System Module and requires therefore no dedicated power distribution unit thus no need for additional space or cabinet.

5.5.2 Requirements


Hardware requirementsThis feature requires Flexi Multiradio 10 BTS.


Functional overviewOptional integrated FPFD outdoor sub-module is a size optimized power distribution unit (PDU). It is located at the top left of the outdoor Flexi Multiradio System Module.

It can be used for stacked configuration and feederless configuration the same way as earlier Flexi integrated Power distribution units. In feederless configuration FPFD can be used with optional Over Voltage Protection units (OVP with FSEC or FSES).

It can be installed together with new Flexi Multiradio System Module in one 3U casing. FPFD Power distribution sub-module provides four external -48 V DC outlets for Flexi Modules (RF Module, RRH, or external System Module) or any standard 48 V DC device at site and one internal DC output to System Module itself.

The FPFD has integrated basic Over Voltage Protection on input (OVP Type approval level with +/- 1 kV (L-L) 8/20 s and +/- 2 kV (L-N) 8/20 s), EMC filtering and reverse polarity protection. It protects the connected units against short circuit, overcurrent (fixed trip points), and high voltage transients.

Figure 30 FPFD sub-module

InterfacesThe FPFD provides the following external interfaces:

One -48 V DC input Four external -48 V DC outputs One internal DC output to the System Module Control panel with the following elements:

one LED for each output (RF1, RF2, RF3, EXT, SYS) SELECT and SET buttons to control their status

Communication with Flexi Multiradio System Module is done via serial interface.

5.6 LTE950: FPFC Flexi Power Distribution ModuleIntroduction to the featureThe optional FPFC is a stand-alone 19 inch rack wide power distribution module for Flexi Multiradio BTS configurations.

5.6.1 Benefits


Operator benefitsThe general-purpose FPFC can be flexibly used at larger outdoor and indoor Flexi BTS sites, or up on a tower, together with Radio Modules or RRHs. It provides six -48V DC outputs with improved Over Voltage Protection (OVP).

5.6.2 Requirements


Hardware requirementsThis feature requires no new or additional hardware.


Functional overviewOptional FPFC is a stand-alone outdoor general purpose Power Distribution Unit (PDU) with Class II Over Voltage Protection, with 15 kA protection level. External overvoltage protection (using, for instance, units of type FSEC or FSES) might be needed with RF parts if the PDU is located more than ten meters away from the powered unit.

FPFC is a stand-alone external 19 inch wide 2U high outdoor module. Power distribution module FPFC provides six outlets for Flexi Modules (Radio Modules, RRHs, or System Module), or any standard -48 V DC device at site. It can also be used, for example, at the top of the antenna mast to distribute power to several RF Modules or Remote Radio Heads. It has one External alarm to indicate Over Voltage Protection (OVP) device con-dition.

To provide more than six outputs, it is possible to chain two FPFCs using the same DC power source.

Figure 31 FPFC module

InterfacesFPFC provides the following external interfaces:

one DC input six DC outputs

CH1-2: maximum fixed output 30A CH3-6: maximum adjustable output 4A/15A/30AAdditionally, each output has On/Off bar.

one EAC connectorEAC connector (RJ45) informs about any abnormal situation, for example, when the protective component(s) have been damaged. It indicates SPD alarm via two alarm signals - Normal Open (NO) and Normal Closed (NC): NO

Alarm is active when the connection is closed. 5V alarm detection line is pulled down during alarm: Active = 0, Inactive = 1.

NCAlarm is active when the connection is open. 5V alarm detection line is pulled up during alarm: Active = 1, Inactive = 0.
