Overview:
The IDM-TDO Telephone Optical Terminal primarily provides 2 telephone interfaces.
The IDM-TDO Telephone Optical Terminal extends voice services to various subscriber areas, serving as a replacement for remote small exchanges, enabling cross-boundary subscriber provisioning, and alleviating the load on switching offices; Alternatively, it resolves the limitations of twisted pair in terms of bandwidth and transmission distance within urban areas, thereby expanding the service coverage of the switching office. This optical terminal equipment can be widely applied in the telecommunications, electric power, banking, public security, military, education, and highway sectors for public switched telephone network (PSTN) access and dedicated line information transmission.
Product Features:
- Adopts a desktop chassis structure design, featuring high integration and compact size;
- 1 channel dual-fiber (single-fiber) optical path;
- Provides 2 standard telephone interfaces with Caller ID (CID) functionality;
- Equipped with comprehensive alarm indication functions;
