KX-TDA0175 Panasonic KX-TDA/KX-TDE Series PBX Expansion Card

The Panasonic KX-TDA0175, also known as the MSLC16, is a 16-port Message Single Line Card designed for use with Panasonic KX-TDA and KX-TDE series hybrid IP-PBX systems. This expansion card provides analogue single line telephone (SLT) ports with integrated message waiting lamp functionality, enabling connection of standard analogue telephones and fax machines to the PBX.

The MSLC16 card is typically deployed in environments where a mix of digital, IP, and analogue endpoints are required. The message waiting indicator support makes it particularly suitable for hospitality applications and office environments where voicemail notification via lamp signalling is needed on analogue handsets.

The KX-TDA and KX-TDE series are legacy Panasonic PBX platforms that have been widely deployed across small to medium enterprise installations. While these systems are now discontinued, they remain in active service at many sites, creating ongoing demand for expansion cards and replacement components.
