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. It supports transmission over fiber, microwave, DDN private networks, or other 2M channels, enabling extension of the operational distance for devices equipped with V.24 interfaces. It is extensively applied in remote interconnection of monitoring data, image processing, and video conferencing systems.

Key Features:

   Synchronous V.24 (RS232): 64K or 128K
   Asynchronous: 300 to 115200 bps
   E1 channel supports optional CRC-4 or 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 automatically
   Allows up to 8ms latency difference among 4 E1 channels—ideal for DDN networks where latency is uncertain
   Real-time monitoring of E1 interface status; automatically disconnects lines with LOS or AIS at both ends; reconnects automatically when line returns to normal
   Comprehensive alarm indication output: provides LOS, AIS, and E1 delay exceeding 8ms alarm outputs
   Supports E1 line loopback function for performance testing of E1 channels
