Product Description:
The Avaya TN2402 Processor Card for CSI (Control, Signaling, and Interface) is the central processing unit for Avaya Definity communication systems configured in Compact Single Interface (CSI) mode. Acting as the system’s command center, the TN2402 manages voice and data routing, call processing, feature execution, system booting, and overall control logic across all active modules.
Designed for medium-sized to enterprise-grade installations, this processor card integrates directly into CSI-configured carriers and supports direct connections with expansion boards such as line/trunk cards, memory modules, and announcement boards. With its robust Motorola processor and high-speed architecture, the TN2402 ensures low-latency system performance, quick feature responses, and seamless call handling.
Key functions include error logging, boot diagnostics, administrative access, and integration with maintenance terminals. It is compatible with various versions of Avaya Communication Manager software and plays a critical role in maintaining system uptime, user call experience, and internal system coordination.
