Hybrid platform SMG-3016 is used as a trunk gateway for reciprocation of signal and media flows of TDM and VoIP networks. The gateway also might be used as an IP PBX with value added services (VAS) support and a multipurpose solution for infocommunication new generation networks (NGN). The wide function-set, strict compliance with require-ments and standards and carrier class reliability allow service providers and carriers to solve most part of their objectives on the basis of SMG-3016.

  SMG-3016 is a beneficial investment in the future of your project due to its scalability. The gateway supports up to 16 E1 streams (SS7, PRI, V5.2) and up to 768 VoIP channels.

IP PBX with VAS support
  Additional options for SMG-3016 gateway allow using it as a full-featured IP PBX for up to 3000 SIP subscribers with support for a wide range of value added services. A programmable IP PBX module ECSS-10 is designed for fast deployment of a VoIP node with a minimum of capital expenses. ECSS-10 and SMG-3016 might be used as a PBX of any level.

Functional compatibility
  The strict compliance with up-to-date protocols’ requirements, recommendations and standards provides functional compatibility with a variety of equipment: digital PBX, IP PBX, Softswitches, VoIP gateways, SIP phones, software SIP clients, etc.

Carrier class reliability
  SMG-3016 provides high level of fault tolerance due to embedded state-of-the-art Quad-Core ARMv8 Marvell Armada 7040 processor, uniform load distribution among submodules, usage of up-to-date technologies based on parallel computing and power modules redundancy. In case of a primary submodule fault, the gateway switches to a backup submodule.
Media streams transcoding
  The hardware transcoding based on Mindspeed Technologies media codecs helps to negotiate media streams with different VoIP codecs which are used in up-to-date networks.

Intellectual protection of IP networks
  The intellectual protection against unauthorized external SIP subscribers connection and connections via http/https/ /telnet/ssh is realized on the SMG-3016 (Dynamic Firewall, Static Firewall, black and white lists of IP addresses and subnetworks, etc.). For additional defense, SMG-3016 may be used in coupling with with session border controller (e.g. SBC-1000) that is used as a firewall for VoIP networks.

RADIUS routing
  Intellectual call routing based on billing system responses via the RADIUS protocol allows you to create flexible methods of call processing.
