Welcome to Synway Technology!

DTP
DATASHEET

The DTP is widely used as a reliable tool for call logging applications developers to passively tap E1/T1 trunks in high-density telephony environments. DTP has been used by many call center applications developers for its multiple signaling capabilities and high compatibility with international standards. Synway's DTP is software configurable for E1/T1 interfaces .

KEY FEATURES AND BENEFITS

Single and Dual Hi-Impedance E1/T1Digital Tap

Tap digital lines with no additional hardware for passive logging applications.

Multiple Call State Monitoring (DSS1/ISDN/SS7)

Support the ISDN, MTP3,TUP, ISUP, DSS1 signaling protocols and report the call states and calls parameters via comprehensible API events.

True Dual Span Capabilities

Customizable RJ-45/BNC/RJ-11 interfaces can record inbound/outbound sides of a conversation, and support inbound and outbound call recording.

Support Direct Windows WAV Format

Data is stored in WINDOWS WAV format directly, and can be played out by sound card with no format conversion.

Voice-Processing Capability

A large selection of voice CODECs for developers, including G711 A-law, μ-law, Linear PCM, IMA-ADPCM, MP3, and support VOX format .

High Density Passive Tap Capabilities

Operating between a central office and PBXs, the DTP's high impedance receivers record both sides of a call without interrupting service. Each board can process up to 60 ports, with a maximum of 480 ports per host.

Tap Environment

With single or dual E1/T1 trunk boards, DTP adapts to high density applications. The Synway's in-house unified API supports a total of 480 ports per system. In any digital environment, DTP can work well as tapping point between office and PBX, office and phones, PBX and phones and any other digital audio signals.

Worldwide Interface Digital Support

DTP supports passive call recording on E1/T1 networks features such as programmable voltage thresholds, voltage detection,and ring detection are managed through Synway's in-house unified API, so the products can easily adapt or be quickly customized to variations in most digital systems worldwide.

Security for User Software

The built-in authorized code identification circuit is included to provide an exclusive authorization code for protecting users' software security.
