IDM-NT202 Telephone Optical Terminal 2 Telephone Channels 2 Ethernet Channels

Overview:

The IDM-NT202 Telephone Optical Terminal extends voice and data services to various subscriber areas, serving as a substitute for remote small exchanges, enabling cross-boundary subscriber allocation, and alleviating the load on switching offices. Alternatively, in urban areas, it resolves the constraints of twisted pair cables in terms of frequency band and transmission distance, thereby expanding the service coverage of switching offices. This device can be widely applied in public telephone network access and dedicated line information transmission for telecommunications data services, power, banking, public security, military, schools, highways and other sectors.

Product Features:

• Desktop chassis design with high integration and compact size;
• 1 dual-fiber (single-fiber) optical channel;
• 2 ordinary telephone interfaces with Caller ID (CID) function;
• 2 groups of shared 100M Ethernet channels; the 2 groups of Ethernet interfaces can be arbitrarily divided into VLANs;
• Comprehensive alarm indication functions;
