Single or Dual T1/E1 Terminate Card

SmartWORKS™ DT/PCM Series

Key Features and Benefits
• Media Control - CODECS
• Tone Detection / Generation
• CallerID/FSK/DTMF/MF Detection
• Activity / Silence Detectors
• Switching (H.100 and MVIP)
• Automatic Gain Control (AGC)
• Automatic Volume Control (AVC)
• Stereo Recording with AGC
• Echo Cancellation
• Call Progress Monitoring (CPM)
• Full-duplex Channels
• Media Streaming
• Live Monitoring
• Start/Stop Call Recording Triggers


Terminate Environment
The SmartWORKS™ DT connects directly to a Central Office or PBX providing line supervision to answer and generate inbound and outbound calls. Each board processes up to 60 channels, with a maximum of 512 channels per system. Each channel has programmable volume control, tone generation, echo cancellation, and Call Progress Monitoring. Outbound dialing and call control is managed through the SmartWORKS™ API.

International ISDN Support

The SmartWORKS™ DT supports Channel Associated Signaling (CAS), and any Q.931 based ISDN variant. Trunk coding and framing is selected on a per framer basis. This allows a single board to control two trunks, each with different settings.

Built in Performance Monitoring

Network conditions and call statistics are available via the SmartWORKS™ API. Event driven alarms are reported for loss of signal conditions or synchronization errors. Framer and call statistics are available through standard API function calls.

Software Switchable T1/E1 Interface

Supports T1 and E1 using the same board. Uses software to switch the telephony interfaces to T1 or E1 on a trunk basis.

Auto-configures for all ISDN variants

Configure to any supported ISDN variant. Save time and reduce operator error when installing and configuring the board in the field.


Calling and called numbers are collected from ISDN signaling packets and passed to the user application via the SmartWORKS™ API.

On-board DSP to complete voice processing

Encoding capabilities, with a rich set of CODECS, reduces the need to purchase other hardware components.

CODEC Support

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