Product Overview

The MTG3000 is the next-generation intelligent relay gateway developed by Dingshin Tongda, designed to meet the business needs of specific industries and carriers. Built on a philosophy of maintainability, manageability, and operability, it features carrier-grade performance, high density, and large capacity. Equipped with SDH synchronous fiber interfaces (STM-1), it integrates advanced capabilities such as IP voice, IP fax, Modem, and voice recognition to help users build flexible, efficient, and future-ready communication networks.

The MTG3000 media gateway supports multiple signaling protocols, enabling conversion between traditional SS7 and PRI signaling and SIP. The MTG3000 supports various codecs with comprehensive encoding/decoding capabilities, along with signaling encryption and intelligent voice recognition technologies. These features ensure high voice quality while optimizing trunk resource utilization, making the solution ideal for access networks of all sizes, from service providers to large enterprises.
