Panasonic KX-TE82480SX 2-Port CO Line & 8-Port SLT Expansion Card

Panasonic KX-TE82480SX 2×8 Card

The Panasonic KX-TE82480SX Expansion Card facilitates the physical expansion of the Panasonic KX-TES824 Advanced Hybrid PBX system. This hardware module integrates two additional Central Office (CO) lines and eight Single Line Telephone (SLT) extension ports into the existing chassis. It utilizes a proprietary bus interface for high-speed communication with the main system processor. Network engineers utilize this card to scale analogue telephony infrastructure without requiring a complete system overhaul. The module supports standard analogue signaling for seamless integration with PSTN networks and legacy handsets. Consequently, it provides a cost-effective path for growing small-to-medium enterprises requiring additional trunk and extension capacity.

Key Features

• Dual CO Line Interface
  The module adds two loop-start analogue trunks to the PABX system for increased external call concurrency and PSTN connectivity.

• Eight SLT Extension Ports
  This component provides eight dedicated ports for standard analogue telephones, fax machines, or wireless local loop terminals.

• Advanced Signaling Support

  • Supports DTMF and Pulse dialing protocols for universal handset compatibility.
  • Facilitates Caller ID transmission (FSK/DTMF) when paired with compatible system modules.

Why Choose This Expansion Module

• Scalable Architecture: This hardware allows for incremental growth, enabling the PABX to reach its maximum 8 CO and 24 extension limit. Therefore, businesses can expand their communication reach as personnel requirements increase.

• Plug-and-Play Integration: The system BIOS automatically recognizes the interface board upon installation. Consequently, configuration time is minimized during maintenance windows.

• Legacy Reliability: This board maintains high-quality voice transmission over standard copper cabling. Additionally, it ensures consistent power delivery to all connected single-line devices.

• Optimized Resource Management: By adding discrete CO lines, the system improves inbound call traffic management. However, it maintains the compact footprint of the original KX-TES824 control unit.
