IDM MSG OVER IP Magneto Telephone Gateway

I. Overview

The IDM MSG OVER IP gateway utilizes large-scale ASIC design to implement the transmission of 1 magneto telephone channel over Ethernet. The device transmission mode can be selected as 1 Ethernet electrical interface or 1 Ethernet optical interface, with a maximum bandwidth of 100M when configured with either interface. The device supports WEB network management configuration, allowing modification of gateway server registration, IP address configuration, telephone call modes, etc. via the WEB page.
