AXE telephone exchange

The AXE is the digital successor to the AKE analogue telephone exchange and ARF/ARM family of crossbar switches.

It is used for connecting local landlines, operating 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 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 implementation of AXE is on a blade cluster system[2] capable of handling up to 8 million subscribers.
