Overview:

The IDM-30EN Integrated Service Multiplexer uses optical fiber as the transmission medium, utilizing standard optical fiber or E1 transmission channels (G.703 standard), adopting the PCM30/32 format to convert telephone service signals or data signals to be transmitted into optical signals for transmission to the remote end via optical fiber; in addition, unlike the IDM-30E Integrated Service Access Device, it can provide two Ethernet services in addition to all services available on the former.
This series of equipment features easy installation, simple operation and maintenance, and high system reliability, and can be widely applied in public telephone network access or private line information transmission in industries such as telecommunications, electric power, banking, and public security.
