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
.. The first system was deployed in 1976. AXE
is an acronym
for Automatic Cross-Connection Equipment
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
), international telephony traffic and signaling.
AXE based equipment are being used as MSC, HLR, SCP, FNR, TSC 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 212 60. 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 01 which is use as MSC and TSC Blade in AXE. The latest implementation of AXE is on a blade cluster system capable of handling up to 8 million subscribers.
