Overview:
The IDM-E1/V.35 Interface Converter and IDM-FE1/V.35 Interface Converter can convert all or part of the E1 timeslots (i.e., N*64K) to a V.35 interface, with bandwidth ranging from 64Kbps to 2048Kbps. They can be widely applied in computer network interconnection, DDN data network access, transmission optimization for mobile telephone networks, and various transmission access applications based on E1 PCM networks.
Product Features:
- Supports transparent transmission and fractional timeslot transmission of V.35 interface data over E1 lines, with bandwidth ranging from 64Kbps to 2048Kbps;
- When using fractional timeslots, the number and position of timeslots can be set arbitrarily;
- Auto-adaptive to the data phase transmitted by DTE devices for easy commissioning;
- Provides multiple loopback setting functions for convenient testing and commissioning;
- Offers both unbalanced 75Ω and balanced 120Ω E1 interfaces;
- Equipped with E1 circuit diagnostic functions;
- Supports network management functions, enabling monitoring of device operation status and configuration of device working states.
