7. AXE PLATFORM From a functionality point of view the BSC can be divided into the following main parts: APZ control system Central Processor, CP The CP has the most processing capacity in the AXE. It is responsible for all high-level functionalities, like the analysis of telephone numbers and processing of charging information. The call setup procedure is one of the main tasks controlled by the CP.       Regional Processor, RP The RP is responsible of controlling all hardware located in the APT switching part of AXE.      I/O System The main task of the I/O system is to connect the user to the AXE in form of Alphanumeric Terminals, Alarm panels and External Media. The examples are: APG 40 and APG 43/2. APT switching system Group Switch, GS The GS is the heart of the AXE. It is responsible for switching of calls, connection of APT equipment and synchronization both internally and externally. The GS is implemented in the XDB boards.     Exchange Terminal, ET The ET connects traffic links to the AXE. There are a lot of different standards for these links where STM-1 (155 Mbit/s) and E1 (2 Mbit/s) are the most common.     Signaling Terminal, ST The signalling terminal is used to communicate with other nodes over signalling links. There exist a lot of different signalling standards. The most common standard for interexchange signalling is Signalling System No.7, SS7. In the access network for fixed telephony a common standard is Digital Signalling System No.1, DSS1.

9. HW Building Blocks

10. CMXB : The CMXB provides the Ethernet switching infrastructure to the EGEM2 subrack with 10 Gbps per slot. Two boards are required per EGEM2 subrack . The CMXB3 supports 10 Gbps and 40 Gbps connections between EGEM2 subracks for user plane traffic. Node external traffic uses up to 4x10 Gbps per CMXB3. CMXB3 works in pairs for 1+1 redundancy.

11. SCXB – System Control Switch Board : SCXB controls the eGEM2 magazine. It provides the same functionality as SCBRP and in addition it also acts as an eGEM2 magazine Ethernet switch and provides accessibility to up to 30 boards via 10/100/1000BaseT with auto negotiation and provide external Ethernet switch accessibility four 10/100/1000/10000BaseT and two 10/100/1000BaseT ports in the front.

12. EvoET : The EvoET board is an optional board to handle TDM transport on Abis .

13. One EVO ET board supports 8 STM-1/OC-3 ports. The operator gets a whole board, but maybe the whole capacity is not required, therefore Hardware Activation Codes (HWAC) are needed to activate required no of ports.

14. EPB : The Evo Processing Board, that is the BSC RP (TRH, GPH, PGW and AGW ). It will be designed to meet the capacity roadmap of the Evo Controller, which implies a high performance processor.

15. EPB1.The capacity of one EPB1 is similar to 7 GARP-2, since each EPB1 adds 7 virtual RPs and each virtual RP has the capacity that corresponds to one GARP-2. APPLICATIONS   TRH – Transceiver Handler Application: TRH is used for signaling towards TRX. One TRH VRP can handle up to 256 TRXs .   GPH – GPRS Packet Handler Application: GPH is estimated to be able to handle up to 512 BPDCH or 256 GEPDCH or a mix thereof .   PGW - Packet Gateway: Capacity per VRP (PGW ) 200 TRXs for Abis Optimization 255 TRXs for Abis over IP A-Interface Gateway: The capacity is the same as in BSS G10B (900 simultaneous calls), except if Abis over IP together with Abis Optimization is used, then the capacity is increased to 2000 simultaneous calls .  

16. CTH (Combined Traffic Handler) Concept A CTH RP should be dimensioned with spare capacity. This so that Super Channel Groups and LAPD links of an RP going out of order can be moved to other RPs. CTH capacity Limit :Up to 512 CTH RPs per BSC

17. In 12B the cores will have fixed allocated function: GPH, TRH, AGW or PGW. In 13B CTH is introduced and can dynamically take on TRH, PGW & AGW functionality, GPH on separate cores, but both CTH and GPH cores can share same EPB1
