The latest implementation of AXE is on a blade cluster system capable of handling up to 8 million subscribers. The latest APZ type is 214 03 which is used as MSC, TSC and HLR Blade in AXE. 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 family of APZs started with APZ 210 03 in 1976 the latest one is APZ 214 03. It runs in parallel sync mode making it fault redundant. The brain of the AXE system is a dual processor system called APZ. It is used for connecting local landlines, operate mobile networks ( TDMA, GSM, CDMA, W-CDMA, PDC), international telephony traffic and signaling.ĪXE based equipment are being used as BSC/TRC, MSC, HLR, SCP, FNR, TSC, STP and wireline nodes. The design is modular with an APZ dual processor running in sync mode, an APT switching part and an APG I/O part. The AXE is the digital successor to the AKE analogue telephone exchange and ARF/ARM family of crossbar switches. AXE is not an acronym, but an Ericsson product code. ![]() It was developed in 1974 by Ellemtel, a research and development subsidiary of Ericsson and Televerket. The AXE telephone exchange is a product line of circuit switched digital telephone exchanges manufactured by Ericsson, a Swedish telecom company.
