Key Features and Benefits
4-24 Port Telephony Cards
Offers low to high density boards that are ideal for any analog environment.
Voltage Detection
Voltage values are reported with standard SmartWORKSTM 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
SmartWORKSTM offers a large selection of voice CODECS (including G.723.1, G.729A and MS GSM)
Tap Environment
The LD series accomodates low to high density environments with 4, 8, 16, or 24 port boards. The SmartWORKSTM 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 SmartWORKSTM 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 SmartWORKSTM API. As a result, the SmartWORKSTM LD easily adapts to variations found on analog systems throughout the world.
Built in Performance Monitoring
Built in voltage detection allows SmartWORKSTM 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.
LD boards connect directly to a standard POTS line or behind a PABX. LD provides passive monitoring of voice conversations and signaling or acts as a point of termination for applications such as IVR, Automated Attendant, and Unified Messaging.
