KX-TDA0290 Panasonic KX-TDA PBX Expansion Card

The Panasonic KX-TDA0290 is an ISDN30e Primary Rate Interface (PRI) line card designed for integration with Panasonic KX-TDA series hybrid IP-PBX systems. This card provides a single ISDN30 (E1) trunk connection, delivering up to 30 simultaneous voice channels for external call handling.

The KX-TDA0290 enables connection to ISDN30e services provided by UK telecoms carriers, making it essential for businesses requiring high-density trunk connectivity. It slots directly into the KX-TDA main processing unit, expanding the system’s external line capacity for medium to large office environments.

The Panasonic KX-TDA platform is a legacy system that has been superseded by the KX-NS series. However, the KX-TDA0290 remains in demand for maintaining and expanding existing KX-TDA installations where ISDN30 connectivity is still in use.
