IDM-E1/V.35 Protocol Converter

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 of mobile telephone networks, and various transmission access based on E1 PCM networks.

Product Features:

• Transparent transmission and timeslot-based transmission of V.35 interface data over E1 lines, with bandwidth ranging from 64Kbps to 2048Kbps;
• When using timeslot-based transmission, the number and position of timeslots can be set arbitrarily;
• Auto-adaptive to the data phase transmitted by DTE devices for easy commissioning;
• Multiple loopback settings for convenient testing and commissioning;
• Provides both unbalanced 75Ω and balanced 120Ω E1 interfaces;
• E1 circuit diagnostic function.
• Network management function to monitor device operation and configure device working status;
