The MTG3000 trunk gateway is a new-generation intelligent trunk gateway designed for the business needs of industries and operators. Based on the design philosophy of maintainability, manageability, and operability, it features telecom-grade reliability, high density, and large capacity. Equipped with SDH synchronous optical fiber interfaces (STM-1), it integrates enhanced functions such as IP voice, IP fax, Modem, and voice recognition, providing users with a flexible and efficient future-oriented communication network. It supports multiple signaling protocols to realize the conversion between traditional signaling (SS7, PRI) and the SIP protocol. The MTG3000 supports various codecs, offering comprehensive codec capabilities, and provides signaling encryption and intelligent voice recognition technologies to ensure voice quality while improving the usage efficiency of trunk resources. It is widely applicable to access networks of various scales, such as operators and large enterprises.
