Easily configurable for analog network opportunities

Designed for analog networks, the SmartWORKS LD has both passive and terminate network interface capabilities. The SmartWORKS LD features programmable voltage thresholds and loop reversal detection and is easily configured to accommodate variations across analog networks. This product is offered in 4, 8, 16 and 24-port versions, suitable for small to large offices and call centers.

  • Tap Environment
    The LD series accommodates low- to high-density environments with 4, 8, 16, or 24-port blades. The SmartWORKS API supports a total of 512 channels per system. The tapping point can be anywhere on an analog line: between Central Office and PBX, Central Office and phones, or PBX and phones.

    Terminate Environment
    The LD series can be used to initiate as well as terminate calls. When configured as an interactive resource, phone lines can directly connect to and terminate on the LD blades. Standard ring detection is available.

    Worldwide Analog Support
    The SmartWORKS LD supports passive call recording on ground start and loop start analog networks. It has line terminating capabilities for loop start environments. Features such as programmable voltage thresholds, voltage detection, and polarity reversal are managed through the common SmartWORKS API. As a result, the SmartWORKS LD easily adapts to variations found on analog systems throughout the world.

    Built-in Performance Monitoring
    Built-in voltage detection allows SmartWORKS LD to distinguish a disruption of service if a cable is damaged or disconnected. This unique feature is only available on the LD series.
