IDM-30EN-32 Integrated Service Access Device
The IDM-30EN-32 Integrated Service Optical Terminal uses optical fiber as the transmission medium, utilizing standard fiber or E1 transmission channels (G.703 standard) with PCM30/32 framing to convert telephone service signals or data signals into optical signals for transmission to the remote end over fiber; in addition, unlike the IDM-30E-32 Integrated Service Access Device, it can also provide two Ethernet service channels in addition to all services available on the former.
