About This Part
The Huawei 03030QCQ, also identified by the model CR2D000IE110, is a high-density 32-Port E1 Physical Interface Card designed for robust digital transmission within carrier-grade network infrastructure. This module integrates seamlessly into compatible Huawei platforms, providing essential connectivity for voice and data services. Operating at the E1 standard (2.048 Mbps per channel), the card facilitates the aggregation and transport of numerous independent digital streams. Its 75-ohm impedance ensures signal integrity over coaxial cabling, a common requirement in telecommunications for reliable short-to-medium distance connections. This Part Number 03030QCQ is critical for systems requiring extensive E1 connectivity, supporting various applications from traditional PSTN interconnections to leased line services and mobile backhaul. The card's design emphasizes high port density and performance, crucial for managing large volumes of time-division multiplexed (TDM) traffic efficiently. This 32-Port E1 interface card is typically deployed in the access or aggregation layers of telecommunication networks, often within Huawei's extensive portfolio of carrier-grade routers, multiservice access platforms, or digital cross-connect systems. It serves as a vital component for telecom operators and Internet Service Providers (ISPs) that need to provision or maintain a large number of E1 circuits. Common use cases include providing connectivity for traditional voice switches (PSTN), integrating legacy TDM-based services into modern IP/MPLS networks, and offering leased line services to enterprise customers. Furthermore, it plays a role in mobile backhaul for 2G and 3G networks, where E1 lines are still prevalent for connecting Base Station Controllers (BSCs) or Radio Network Controllers (RNCs) to the core network. The card's high port density enables efficient space utilization and simplifies network architecture by consolidating multiple E1 terminations onto a single module, thereby reducing operational complexity and capital expenditure for network expansion or upgrades.
