Avaya 847138880 CO Trunk TN465C RHS circuit card for Definity/G3 PBX systems.

The Avaya 847138880 (also referenced as 700394513) is a TN465C Central Office (CO) Trunk circuit card designed for Avaya Definity and G3 series PBX systems. This Right-Hand Side (RHS) card provides analogue trunk interfaces, enabling connectivity between the PBX and the public switched telephone network (PSTN) via CO trunk lines.

The TN465C is deployed within Definity cabinets to deliver standard CO trunk functionality, supporting inbound and outbound call routing through traditional analogue telephone lines. It is typically used in enterprise telephony environments where PSTN connectivity remains essential alongside digital or IP infrastructure.

This is a legacy product associated with the Avaya Definity platform, which has been succeeded by more recent Avaya Communication Manager and Aura systems. However, the TN465C remains in demand for maintaining and expanding existing Definity installations where analogue trunk capacity is required.
