DTP (1-4E1/T1/J1)

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
  • Single, Dual or Quad 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, CAS 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.
  • ap 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.
