Ensuring reliable communication in critically short timeframes

PCM30U-OCH is a family of transmission systems based on PDH and SDH multiplexers, designed for the transmission of standard telecommunication signals such as voice, data, and Ethernet (bridge), as well as protection signal commands in analog (binary contacts) or digital form with various protocols (e.g., C37.94). Additionally, the system provides 50 Hz frequency transmission for specific solutions. The PCM30U-OCH solution allows for cost optimization according to individual functional variants based on specific customer needs. The system focuses on high reliability for the transmission of critical signals. The system offers full compatibility with analog and digital protection systems from various vendors, providing transmissions for optical interfaces of differential protection systems from ABB, SEL, and SIEMENS.
