AASTRA PBX958.EXP.A470-1C PBX expansion module for Aastra 400 series telephone systems.
The AASTRA PBX958.EXP.A470-1C is an expansion module designed for Aastra PBX telephone systems. This card extends the capabilities of the base PBX unit by providing additional interface capacity or functionality within the Aastra 400 series communications platform.
This expansion module is typically deployed in enterprise telephony environments where the core PBX system requires additional port density or feature expansion. It slots into the main PBX chassis to scale the system as organisational communication needs grow.
The Aastra 400 series and associated expansion hardware represent legacy telephony infrastructure. While these systems remain operational in many installations, they have been superseded following Mitel’s acquisition of Aastra. This module is suited for maintaining and extending existing Aastra deployments.
