E1/V.24 Interface Converter

Overview:

    The TRX E1/V.24 interface converter enables transparent conversion between E1 transmission channels and V.24 interfaces, widely used in data communication equipment. Suitable for fiber, microwave, DDN private networks, or other 2M channels, it extends the operational distance of devices with V.24 interfaces. Widely applied in remote interconnection of surveillance data, image processing, and video conferencing equipment.

Key Features:

   V.24 (RS232) synchronous: 64K or 128K    asynchronous: 300~115200 bps

   E1 channel supports optional CRC-4 and non-CRC-4 check modes;

   Maximum transmission bandwidth up to 7.68 Mbps, supporting high-quality video surveillance systems;

   On reset, automatically detects the number of E1 channels and latency, then selects available E1 channels;

   Allows up to 8ms delay difference among 4 E1 channels, making it the optimal choice in DDN networks where latency is uncertain;

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

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

   Features E1 line loopback function for convenient performance testing of E1 channels;
