Tap Environment
The LD series accomodates low to high density environments with 4, 8, 16, or 24 port boards. 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 boards. Standard ring
detection is available.

World-Wide 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 feature is unique in the industry and only
available on the LD series.

4-24 Port Telephony Cards

Offers low to high density boards that are ideal for any analog environment.

On Demand Voltage Detection

Voltage values are reported with standard SmartWORKS™ API events to simplify application development.

Programmable Voltage Thresholds

Control voltage detection event reporting with ease by adjusting the board to the local analog environment.

Detects Polarity Reversal

Adapts to environments where Tip and Ring are reversed.

Minimum 18k Ohm Impedance

High impedance receivers record both sides of a call without interrupting service.

CODEC Support

SmartWORKS™ offers a large selection of voice CODECS (including G.723.1, G.729A and MS GSM)
