blocks

5 Flexi Multiradio 10 System Module operation

and main blocks
Flexi Multiradio System Module is an integral part of Flexi Multiradio 10 BTS. For GSM-
R, it supports the following software operating mode:

• GSM/EDGE

g Note: GSM Railway currently does not support the following capacity extension
modules:

472182A FBBA Capacity Extension Sub-Module

472797A FBBC Flexi Capacity Extension Sub-Module

With Flexi Multiradio 10 BTS the user can build a site in a flexible way, that is adjusted to
needs.

g Note: RFM modules can be connected as plug-and-play unit in the fast delivery mode
to Multiradio 10 System Module-based configurations only.

The tasks of the System Module are:

• telecom control
• system operation and maintenance
• baseband processing
• transmission
• synchronization
• power distribution via optional sub-module

The following version of Flexi Multiradio 10 BTS System Modules is available for GSM-R:

• Flexi Multiradio System Module Outdoor FSMF (472181A)

5.1 Flexi Multiradio 10 System Module Outdoor

The outdoor Flexi Multiradio 10 System Module FSMF consists of:

• casing of the height of three standard rack units

• weatherproof core module
• fans

The fan assembly is connected with a cable to the core module. All these items form a
single sales item. The core module has the control and baseband processing
functionality of the BTS. It contains also up to two integrated Gigabit Ethernet transport
interfaces for the backhaul.
Additional optional equipment that can be installed in the System Module casing is:

• up to two capacity extension sub-modules

• one transport sub-module

5.2 Capacity Extension Sub-Module

Capacity extension sub-module allows increasing of the BTS capacity. It can be inserted
into the casing, providing additional signal processing power to the system. Adding the
capacity sub-modules in the field does not affect the ongoing traffic. The following
capacity extension sub-modules are available:

• FBBA for FSMF (472182A)

• FBBC for FSMF (472797A)

FBBA is powered by the core module. The second sub-module is powered by the first
one. Every extension sub-module is connected to the core module through QSFP
connector.
In case of FBBC both sub-modules are powered directly by the core module via Y-cable.
Similarly to FBBA, every extension sub-module is connected to the core module through
QSFP connector.
For more information on cabling, see Cabling Flexi Multiradio 10 BTS.

5.3 Transport options

5.3.1 Flexi Multiradio 10 System Module (FSMF)

Flexi Multiradio 10 BTS System Module FSMF is equipped with two integrated transport
interfaces: electrical Gigabit Ethernet (GE) interface (EIF1) and optical interface
(EIF2/RF/6).

The latter is SW configurable for transport purposes or for RP3-01 interface. To operate
in either (transport or RP3-01), it requires a Small Form-factor Pluggable (SFP). Both
Ethernet interfaces provide a physical interface to the backhaul network.

g Note: In GSM the optical interface (EIF2/RF/6) is available as transport interface EIF2
if the optional transmission sub-module (FTIF) is not deployed.

Flexi Multiradio 10 System Module FSMF is optimized for Ethernet Transport, and the
HW supports the following integrated transport functions (without the optional
transmission sub-module):

• 1 x 100/1000Base-T Ethernet port

• 1 x optional optical SFP (depends on configuration)
• Ethernet based chaining and switching across up to two interfaces
• IEEE1588-2008, Synchronous Ethernet, 1PPS and 2.048MHz1)

g Note: There is a possibility to install an optional transmission sub-module (FTIF) to

extend Flexi Multiradio 10 BTS transport capabilities.
The FTIF transmission sub-module is needed, for example: for GSM legacy Abis
support.

5.4 Power distribution options

Power distribution module provides 48 V DC power output connectors for power

distribution to RF Modules, Remote Radio Heads, capacity extension System Modules,
or any standard 48 V DC device at the site.
The following optional power distribution modules are available:

• power distribution sub-module (FPFD) for near-by-located devices.

Note that FPFD is installed in the System Module casing (see Front panel of the
System Module). When it is installed, it also powers the core module via an internal
connector (MEC8). Hence, the FSMF DC IN interface must not be used.
• stand-alone power distribution module (FPFC) for feederless sites mainly.

For more information, see Flexi Multiradio BTS Optional Items Description.

5.5 Optional items

Optional items are the elements that do not belong to the above-mentioned categories.
Optional items are, for example:

• Flexi Mounting Kit for Floor, Wall, and Pole (FMFA)

• Flexi Cabinet for Outdoor (FCOA)

For more information, see Flexi Multiradio BTS Optional Items Description document.

DN09259792 Issue: 1-0-0 © 2018 Nokia. Nokia confidential. 17

Synchronization Flexi Multiradio 10 BTS System Module Description

6 Synchronization
The Flexi Multiradio 10 BTS requires accurate timing information. It can be extracted
from:

• the TDM-based network interface

• the packet network via:
– Timing over Packet
– Synchronous Ethernet

• the 2.048 MHz signal

• another Flexi BTS or a legacy BTS
• the Global Positioning System (GPS)
• the BeiDou Navigation Satellite System
• the Global Navigation Satellite System (GLONASS)
• the GPS GLONASS Receiver Antenna (FYGB)
• the Flexi GPS Box (FYGD)
• the Flexi Enhanced External GPS Box (FYGE)
• the Outdoor External GNSS Enhanced Holdover (FYGG)
• the Outdoor GNSS receiver (FYGM)

FSMF does not contain an integrated GNSS (GPS and GLONASS) receiver, and so
requires an additional unit. The full list of available units can be found in Flexi Multiradio
Base Station and Flexi Multiradio 10 Base Station Optional Items Description.
FYGM is compatible with existing legacy Sync-In port and plug-and-play to existing
synchronization features in FSMF.

g Note: The BTS-internal clock source can also be used for a limited period if the
external timing reference is lost.

In the Ethernet transport case, the timing information can be carried over the Ethernet-
based network using the Timing over Packet functionality, where specific timing packets
are sent over the network from a master clock to the BTS.
If Synchronous Ethernet generation is required, FSMF must contain FTIF.
If PCM frequency (Abis 2048000 Hz/E1/T1) is used as reference for BTS, and:

• If PCM frequency is faulty from BTS start up time:

– Oven tuning starts.
– If faulty situation continues for 48 hours, frequency degradation detection starts
afresh.

• If PCM frequency is detected faulty in run time:

– Tuning cycle is paused.
– If faulty situation continues for 48 hours, tuning cycle starts from the point where
it was paused.

Flexi Multiradio 10 BTS System Module Description Interfaces

9 Interfaces
All interfaces of the System Modules, capacity extension sub-modules, and transport
sub-modules are located on the front panel.

OBSAI RP3-01 line can handle up to 6.144 Gbps, that is, it can transfer up to 32
WCDMA carriers via one link. Hence, it allows creating very large RF configurations. For
CPRI the following line rates are supported: 1.228, 2.45761, 4.9152, and 6.144 Gbps.
BTS internal communications between sub-assemblies is done with SRIO (6.25 Gbps
line rate) which provides very fast and low latency interface and allows the operator to
utilize advanced receiver algorithms.
SRIO and OBSAI RP3-01 interfaces are used also as communication channels between
the first System Module and the expansion System Modules. The SRIO switch supports
Link Layer Encryption scheme on 4 of its 16 ports. Encryption is used for external
interfaces to protect them against possible intruders.

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

external transport, that is, interfacing towards
the RAN, or directly towards the CN.

EAC HDMI External Alarms and Controls (EAC) interface

provides six alarm signals and six SW
controllable interfaces that can be assigned to
support either control or alarm signals.

SYNC IN HDMI HDMI-based input and output external

synchronization interfaces enable, for example,
SYNC OUT HDMI interfacing to GPS equipment.

10 LEDs
System Module and capacity extension sub-module have tricolor LEDs on the front panel
to indicate the operational status of the module and all fault conditions during operation.
It is recommended that you read the information on the LED indications carefully. A
blinking red LED does not always require removing of the module.
