KX-TDA100 Panasonic KX-TDA100 PBX Module

The Panasonic KX-TDA100 is the main cabinet, or Key Service Unit (KSU), for the KX-TDA100 hybrid IP-PBX telephone system. This listing is for the cabinet enclosure only, without cards or power supply. The KSU provides the physical housing and backplane for system cards, expansion modules, and trunk interface boards.

The KX-TDA100 forms the core of Panasonic’s mid-range hybrid PBX platform, designed to support a blend of traditional TDM telephony and IP communications. When fully populated, the system supports up to 108 extensions and integrates analogue, digital, and IP endpoints within a single chassis.

The KX-TDA series has been discontinued by Panasonic and superseded by the KX-NS series. However, the KX-TDA100 remains widely deployed in small-to-medium business environments, and spare cabinets are sought for system replacements, migrations, or capacity consolidation projects.
