Ericsson AXE

The AXE telephone exchange is a product line of circuit switched digital telephone exchanges manufactured by Ericsson, a Swedish telecom company. It was developed in 1974 by Ellemtel, a research and development subsidiary of Ericsson and Televerket.[1] The first system was deployed in 1976. AXE is not an acronym, but an Ericsson product code.

The AXE is the digital successor to the AKE analogue telephone exchange and ARF/ARM family of crossbar switches. The design is modular with an APZ dual processor running in sync mode, an APT switching part and an APG I/O part. It is used for connecting local landlines, operate mobile networks (TDMA, GSM, CDMA, W-CDMA, PDC), international telephony traffic and signaling.

AXE based equipment are being used as BSC/TRC, MSC, HLR, SCP, FNR, TSC, STP and wireline nodes.

The brain of the AXE system is a dual processor system called APZ. It runs in parallel sync mode making it fault redundant. The family of APZs started with APZ 210 03 in 1976; the latest one is APZ 214 03. The parallel sync mode was partly abandoned in the APZ 212 40 and subsequent models and has been replaced with a warm standby scheme.

The latest APZ type is 214 03 which is used as MSC, TSC and HLR Blade in AXE. The latest implementation of AXE is on a blade cluster system[2] capable of handling up to 8 million subscribers.

The core of the switching part was the Group Switch, initially a time-space-time multiplexer capable of switching up to 64K positions or connections. This Group Switch later evolved to a Distributed Group Switch using Time-Space switching technique with a maximum capacity of 512K.

AXE nodes have evolved as a traffic controller, having the new Media Gateway node running on CPP platform handle the payload traffic.

Ericsson AXE telephone exchanges support lawful intercepts via the remote-control equipment subsystem (RES), which carries out the tap, and the interception management system (IMS), software used for initiating the tap, which adds the tap to the RES database. In a fully operating lawful interception system the RES and IMS both create logs of all numbers being tapped so that system administrators can perform audits to find unauthorized taps.

Code is written in PLEX (a proprietary programming language tied to the AXE hardware, designed by Göran Hemdahl),[3]SDL and ASA210C programming languages. Code for Regional Processors (controlling hardware Extension Modules) is written in ASA210R.

The AXE product line was used in the United Kingdom under the name System Y to supplement and replace the System X by General Electric Company plc.[citation needed]

Wallis Dudhnath - 4th July 2018 (20:11 GMT) Hi Edson, If you have a production AXE10 then you must have a mini test plant where you can test new configurations (Data Transcript) and new patches / fix files. In the past I have used an 'unused' EMG on a Production AXE10 to perform some basic tests. This approach comes with a major government health warning. Let me know what what is failing and I will see if I have encountered your issue. VBR/ Wallis Dudhnath Edson Firmino da Silva - 23rd June 2018 (15:12 GMT) Hi friends need to know about a test system to see ts failures in emg wallis dudhnath - 1st July 2015 (15:25 GMT) Just in case you are interested with ASA machine code. This will give you a feel for the Registers, Instruction Set, etc. Used by ASA (Assembler for AXE10):- 652.

EP; 00FD 0177 Wallis Dudhnath - 28th June 2015 (06:14 GMT) Some other good AXE10 commands that I remember:- SYRIP: SURVEY; (checks the Software) PLLDP; (processor load information) ALLIP; (Alarm list) SYREI: Rank=LARGE/SMALL; (Very careful use) PCORP: BLOCK=BUNGA; (Checks if a Correction has been loaded) SYFAP; (Check for hangings) Please note that there are over one hundred AXE10 MML (Man-Machine Language)commands. The link with MML, PLEX and ASA was a powerful combination. VBR/ Wallis Dudhnath Wallis Dudhnath - 20th June 2015 (08:49 GMT) For TestSystem a good understanding of the AXE10 'blocks' (RE, REICH, PREA, REIBA, REIAA, FOAM, etc.), MML commands, PLEX and ASA really helps you to get upto speed with TestSystem. In the past (circa 1990s) patches could be deployed on a live switch using TestSystem. In fact, 'punching' variables using 'SET (T)VAR' and 'PRINT VAR' was a common practice. At the time there was other switches that was based on BTCoral66.

Periodically, this required a decompiler (DCD) to ensure that the executing code and data was correct. Wallis Dudhnath - 19th June 2015 (14:24 GMT) Using AXE10's Test-System comes with a government health warning. It can crash your system. Below is an example of Test-System.

The software and hardware is divided into Central and Regional components. The Central Processor (usually just referred to as the CP) is called APZ and the trace examples here are from APZ 212 02 from the early 1990's in most cases.

The APZ CP is literally a real-time supercomputer. The data store, program store and signal buffers are actually separate pieces of hardware. Everything from instance variables to marshaled signals between function blocks is all preallocated. Language that is used is PLEX.

The APZ (processor) used ASA (Machine/Assember code). PLEX was based on a 'block' and 'signal' approach. In fact, when I look back it uses a several principles from OOPs. Michael King - MSCEngineer - 1st August 2014 (21:44 GMT) Where would you find the data to interpet software errors on the AXE-10 excluding the E-module in ALEX. Command SYRIP:SURVEY,SYRIP:LOG and SYRIP:EVENT=XXX; is there anyhtinh else available? Thank You BINDU - 25th January 2012 (13:02 GMT) HI I NEED BSC CALL TRACING COMMANDS can you send ME THANKS bert - 18th September 2010 (09:22 GMT) test system Is only for experts,who are trained to use it.

When misused it can destroy the whole switch with one command. Other messages Other messages: Post a reply to this article Name Enter your name. Message Enter your message.
