E1/T1 ISDN PRI/SS7 Gateway
  • Compact 1U form factor for 1/2/4/8/16/64 E1/T1 Ports

  • Compliant with SS7/SS1/ISDN/MF R2 Globally

  • Best Cost for SMB, and Telco Reliability For Carrier

  • Telecom Resilience and Voice Quality

With a more efficient manner to interconnect and deliver large-scalability services, The Synway SMG2000/3000 E1/T1 gateway enables enterprises, service providers and carriers to maximize the value of their networks and services. The SMG2000/3000 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.

It connects IP and hybrid networks via telephony and E1(T1 or STM-1)/Ethernet links in a compact 1U form factor appliance, and 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 offers significant reductions in investment and operational cost when compared to less integrated alternatives.

The enterprise-oriented SMG2030L/2060L, with mini size for better space and shipment efficiency, are unparalleledly cost effective and compliant with PRI ISDN, R2 and SS7 packets, adopting dedicated DSP chipsets for processing IP/TDM signaling and optimizing voice quality. Compared to with rival products, it features high reliability and unmatched cost and delivers a perfect alternative option for enterprises, operators and system integrators.
