Flexi Multiradio 10 System Module operation
Flexi Multiradio System Module is an integral part of Flexi Multiradio 10 BTS. It supports the following software operating modes:
- GSM/EDGE
- WCDMA
- HSPA, HSPA Evolution
- LTE in FDD and TDD
They are supported either in a dedicated or a concurrent mode of operation. The concurrent mode functionality can include several radio access technologies and their combinations, for example: GSM-LTE, GSM-WCDMA, WCDMA-LTE, GSM-WCDMALTE.
Flexi Multiradio 10 BTS also supports multi-operator cases (MORAN) where several operators can share resources of one BTS.
With Flexi Multiradio 10 BTS the user can build a site in a flexible way, that is adjusted to needs:
- System Module can act as a System Extension Module operating in a baseband extension mode. Flexi Multiradio 10 BTS architecture supports chaining of up to nine System Modules. It thus enables building of very high capacity sites and different redundancy solutions.
- Multiband support - RF Modules for different frequency bands can be connected to the same System Module.
- Cooperation with the existing Flexi Multiradio BTS and sharing the same network interface, synchronization, and power distribution units.
1. Flexi Multiradio 10 System Module Outdoor (FSMF) Hardware

| Extension Capacity Module FBBC |
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
- one power distribution sub-module
The capacity extension sub-modules are connected with cables to the core module. Other two sub-modules are connected through internal connectors. The System Module has no backplane. All modules are outdoor-capable, IP65-sealed modules.
Transport options
Flexi Multiradio 10 Base Station 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.
Note: In WCDMA and LTE the optical interface (EIF2/RF/6) is available as transport interface EIF2 if not used for RP3-01 connection.
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)
- LTE S1/X2, or WCDMA Iub/IP, or GSM Packet Abis over Ethernet backhaul interfaces
Note: The reset button is located under the EIF1 interface. Press the reset button for 5 seconds to clear configuration data. Manual reset is required afterwards for changes to take effect.
