KX-TDA0174 Panasonic KX-TDA/KX-TDE Series PBX Expansion Card

The Panasonic KX-TDA0174 is a 16-port single line extension card designed to expand analogue extension capacity within Panasonic hybrid IP-PBX telephone systems. This card provides connections for standard analogue telephones, fax machines, and other single line terminal devices.

The KX-TDA0174 is engineered for use with the Panasonic KX-TDA and KX-TDE series of business communication systems. It slots directly into the main processing unit, allowing administrators to scale their telephony infrastructure by adding additional analogue endpoints without requiring separate external hardware.

This is a legacy product associated with Panasonic’s discontinued TDA/TDE PBX platform. While no longer in active production, these systems remain deployed across many business environments, and expansion cards like the KX-TDA0174 continue to be sought for maintenance, upgrades, and system expansions.
