About This Part
The Huawei 03030REY, also known by its internal designation CR2D000DE111, is a high-density 16-Port E1 Physical Interface Card designed for robust telecommunications infrastructure. This modular line card integrates seamlessly into compatible Huawei transmission and access platforms, providing essential connectivity for Time-Division Multiplexing (TDM) services. Each of the sixteen E1 ports operates at a standard data rate of 2.048 Mbps, adhering to the ITU-T G.703 specification for digital transmission. The card is engineered with a 120-ohm impedance, ensuring optimal signal integrity and compatibility with a wide range of existing E1 network deployments. Its primary function is to aggregate and transport multiple E1 circuits, supporting critical voice, data, and signaling traffic across various network segments. The Part Number 03030REY is crucial for operators requiring reliable, high-density E1 termination within their core or access networks, facilitating the delivery of traditional circuit-switched services. This Huawei 16-Port E1 Physical Interface Card is typically deployed in central offices, remote terminals, and data centers where E1 connectivity is paramount. It serves as a vital component within Huawei's comprehensive portfolio of Multi-Service Transmission Platforms (MSTP) and access network solutions, enabling the aggregation and distribution of E1 circuits for various applications. Telecommunication operators, internet service providers, and large enterprises frequently utilize this card to support traditional voice services, leased lines, and signaling links for mobile backhaul or fixed-line infrastructure. The 03030REY effectively addresses the ongoing need to integrate and manage legacy TDM traffic within modern network architectures, providing a reliable bridge for services that have not yet migrated to IP-based solutions. Its high port density allows operators to maximize rack space and reduce operational complexity by consolidating multiple E1 streams onto a single modular unit, thereby optimizing network resource utilization and ensuring seamless service delivery for critical applications.
