 MDA Series Analog Gateway
Carrier-class reliability ● Supports fault detection and network management alarms. ● Low power consumption and high integration. ● Support three levels of lightning protection standards. ● Supports over-voltage over-voltage protection for POTS interfaces. ● Smaller, higher-quality communications power supply with ripple protection, surge protection, power line bonding and other protections, stable output, high reliability, and instantaneous power-off protection are supported. ● The use of shielded electromagnetic radiation characteristics of the chassis, the electromagnetic compatibility, ROHS and other aspects of a professional design, can effectively shield all kinds of environmental electromagnetic interference. ● Transmission loss, loss frequency, nonlinear distortion, cross-talk attenuation, cross-over noise, and non-overlapped noises meet carrier-grade standards. Flexible and powerful functional strategies ● Support administrator login and password protection, with its own firewall function, can effectively prevent various network virus attacks and improve data security. Rich protocol support capabilities ● Supports SIP, MGCP, and H248 protocols. ● SNMP network management protocol is supported to implement centralized network management, remote monitoring, and maintenance of devices. ● Supports T.30, T.38, and VOICE transparent transmission protocols to implement fax services on IP bearer networks. ● Supports RTP/RTCP protocol for real-time voice packet encapsulation and voice playback. Perfect business support capabilities ● Support voice, fax, Modem business. ● Supports various voice basic services and supplementary services. ● Switch between IP phones and traditional PSTN phones. Flexible access method ● Support IP line access. ● Support xDSL dial-up access. ● Supports Cable Modem access. Diversified management methods ● Support SNMP-based remote centralized device network management. ● Support Web-based device network management. ● Strong QoS guarantee. ● Supports IPv4-based Tos and DiffServ services to ensure voice priority. ● Supports IEEE802.1P, IEEE802.1Q.
