Panasonic KX-NS5170 4-Port Hybrid Extension Card DHLC4

KX-NS5170 Hybrid Interface

The Panasonic KX-NS5170 Extension Card is a 4-port digital hybrid line circuit (DHLC4) engineered for the KX-NS500 and KX-NS700 communication servers. This expansion module enables the simultaneous connection of digital proprietary telephones, single-line analog phones, and DSS consoles. It utilizes a high-density architecture to maximize port availability within a single physical slot.

Key Features

• DHLC4 Architecture
  Each physical port on the circuit board supports hybrid connectivity for analog and digital devices.

• D-XDP Support

  • Allows two digital proprietary telephones to share one port.
  • Increases total extension capacity without extra hardware.

• RJ45 Connectivity
  The module utilizes standard RJ45 interfaces for all four hybrid line connections.

The internal logic of this hardware handles complex signal conversion between digital and analog protocols. Consequently, network engineers can deploy legacy analog hardware alongside modern digital handsets on the same physical infrastructure. The signaling protocol utilizes standard balanced pairs for SLT communication. However, it simultaneously employs proprietary digital signaling for DPT endpoints.

Installation involves inserting the module into a dedicated expansion slot on the PBX main unit. It interfaces directly with the system backplane to ensure low-latency communication. Additionally, the card includes integrated Caller ID (FSK) support for all single-line telephone ports. Therefore, users maintain access to essential identification features across analog hardware.

This system also provides power management for connected digital proprietary telephones. It eliminates the requirement for external power adapters at individual workstations. For large-scale deployments, the card supports message waiting lamps for analog handsets. This ensures that basic devices remain compatible with advanced unified communication features.
