Panasonic KX-TE82480SX 2×8 Expansion Card

Panasonic KX-TE82480SX 2×8 Expansion Card

The Panasonic KX-TE82480SX 2×8 Expansion Card expands compatible KX-TES824 and KX-TEM824 business telephone systems. It adds two analogue Central Office lines and eight Single-Line Telephone extensions. Therefore, growing offices can connect additional external telephone lines and conventional analogue devices without replacing the complete Private Branch Exchange system. It suits small businesses, reception areas, clinics, schools, and retail operations.

Product Overview

The KX-TE82480 provides two ports for analogue public telephone lines. These ports increase the number of incoming and outgoing external connections available to the PBX. In addition, eight Single-Line Telephone ports support compatible analogue telephones, fax machines, modems, answering machines, and similar line-based devices.

The Panasonic KX-TE82480SX 2×8 Expansion Card installs internally within a supported PBX. On a KX-TES824, it can also be mounted above a KX-TE82483 expansion card. However, installation requires the system to be powered off and disconnected from the electrical supply.
