E1/V.24 Interface Converter

Overview:

    The TRX E1/V.24 Interface Converter completes the conversion between a transparent E1 transmission channel and the V.24 interface. It is widely used in data communication equipment and is suitable for extending the working distance of devices with V.24 interfaces over fiber, microwave, DDN private networks, or other 2M channels. It is widely applied in remote interconnection of surveillance data, image processing, video conferencing, and other equipment.

Main Features:

   V.24 (RS232) Synchronous: 64K or 128K    Asynchronous: 300~115200bps

   E1 channel supports CRC-4 and non-CRC-4 error checking modes;

   Maximum transmission line bandwidth is 7.68Mbps, supporting high-quality image surveillance systems;

   Automatically detects the number and delay of E1 lines upon reset and automatically selects the available E1;

   Allows up to 8ms delay difference among 4 E1 lines; this device is the optimal choice in DDN networks where delay is difficult to determine;

   Real-time monitoring of E1 interface status; automatically cuts off lines with LOS or AIS at both ends, and automatically reconnects when the line recovers;

   Complete line alarm indication output, providing LOS, AIS, and E1 delay exceeding 8ms alarm outputs;

   E1 line loopback function for convenient E1 channel performance testing;
