Description

The Nortel NT7Q33AA is a high-capacity Extended Capacity Core (E5 XCC) cross-connect board designed for the Passport 15000 and 20000 multiservice switch platforms. This module provides a 12.5 Gbps (12G5) switching fabric per slot, functioning as the central switching matrix for the chassis. It is responsible for the efficient routing and switching of ATM, Frame Relay, and IP traffic between various line cards and processor modules. The board ensures non-blocking architecture, maintaining high-speed data integrity and low latency across the backplane for carrier-grade telecommunications services.The NT7Q33AA supports redundant configurations, allowing for 1+1 protection schemes where two XCC boards operate in an active/standby or load-sharing mode to prevent system-wide outages. It features integrated synchronization circuitry to ensure precise timing across the switching fabric, which is critical for maintaining cell and frame alignment in multiservice environments. The module is equipped with specialized ASICs for high-speed cell switching and includes comprehensive diagnostic indicators for monitoring link status and hardware health. It is fully hot-swappable, enabling maintenance and capacity upgrades without system downtime. The board interfaces directly with the high-speed midplane of the Passport chassis, facilitating seamless communication between all installed interface modules.
