DUC-E series PRI Gateway

DUC-E series PRI Gateway

  • 1, 2 Port Available
  • SIP to PRI & PRI to SIP
  • 30 Sessions
  • 2 *100 Base-T Ethernet for VoIP payload and signaling


With a more efficient manner to interconnect and deliver large-scalability services, The Dasscom DUC E1 enables service providers and carriers to maximize value of their networks and services. The Dasscom DUC E1 converts digital PSTN message into IP formats and connects and secures sessions across IP and mixed network boundaries to support the seamless delivery of services.
The Dasscom DUC E1 connects IP and hybrid networks via telephony and E1(T1 or STM-1)/Ethernet links in a compact 1U form factor appliance. It also transforms media and signaling to support efficient and reliable voice, fax and multimedia sessions for mobile, fixed and cloud-based applications. The convergence of IP multimedia and TDM gateway functionality in a single chassis in the DUC offers significant reductions in investment and operational cost when compared to less integrated alternatives.
Inbuilt call classification/analytics is vital for hi-density OBD applications, including predictive dialing, dialer, telemarketing and more. It helps minimize dialing cost and maximize value of dialing (human and network) resources. With call classification, OBD applications could improve dialing efficiency by up to 60% and deliver high satisfaction for both agents and subscribers.

Key Features

● Flexible Scalability
From 30 to 60 simultaneous SIP sessions with multimedia transcoding provides high performance in a small footprint to help lower ownership cost and operational cost; a broad range of gateway toolkits help gateway’s maintenance and software upgrading for Web UI, gateway services and firmware.

● Flexible and efficient Gateway Solution
Provide a clear migration path to an all-IP network. It can scale up to 60 simultaneous IP sessions and at the same time provide media transcoding and impressive sessions per second performance; Support SS7 signaling, call routing, call automated failover from IP to TDM for outbound routing.

● Any-to-Any Signaling and Transcoding

Provide any-to-any network connectivity through its ability to interwork multiple protocols to deliver services. It can provide interworking between SS1, R2, ISDN, SS7, SIP formats and any-to-any media transcoding for popular voice codecs, T.38 and G.711 fax interworking, RTP, INBAND and SIPINFO.

● User-Friendly Management & Toolkits
