Flexi EDGE 18/36 TRX System Module

The new Flexi EDGE 18/36 TRX System module provides the GSM/EDGE specific functionality within the Multiradio BTS. It stores and runs the GSM/EDGE BTS SW and provides the GSM/EDGE specific external and internal BTS functions.

There are two variants of Flexi Multiradio System Module; with integrated baseband processing capacity: ESMB for up to 18 and ESMC for up to 36 GSM/EDGE TRX capacities. The ESMC provides maximum capacity, however in most applications the capacity of ESMB is sufficient. As the ESMB can be duplicated and chained, operator can start the site build-out either with ESMB or ESMC with both tracks providing expansion path to maximum system capacity (36TRX/BCF).

EDGE System Module has following main functions:

• GSM/EDGE BTS O&M,

• Abis and transport,

• OBSAI connectivity,

• power distribution to the radios,

• GSM/EDGE baseband

• BTS synchronization.

The BTS O& function in Flexi Multiradio System module unit takes care of Radio Software management, Configuration management, alarm handling and recovery, reference clock management and externals alarms and controls.

ESMB/ESMC has an integrated transport unit which provides the physical transmission interfaces and the transport functionality of the BTS. Six different network interface alternatives are offered: E1 symmetrical, E1 unsymmetrical, T1, Fast Ethernet, Gigabit Ethernet and Flexbus.

These transport interface variants are same as with Flexi EDGE System Module ESMA.
