RPM603386/100 Ericsson TAU2680 Telecom Module

The Ericsson RPM603386/100 is an X.21 adapter cable designed for use with the TAU2680 transmission access unit. This cable provides the physical interface connection required for X.21 protocol data communications, enabling connectivity between the TAU2680 and external network equipment or data terminal equipment.

The TAU2680 is part of Ericsson’s transmission access portfolio, typically deployed in telecommunications networks for multiplexing and data transport applications. This adapter cable is an essential accessory for installations requiring X.21 serial interface connectivity, commonly used in legacy WAN and leased line configurations.

As with much of Ericsson’s earlier transmission equipment range, the TAU2680 and its associated accessories represent legacy telecommunications infrastructure. However, these systems remain in active service across many operator networks, creating ongoing demand for spare parts and replacement cables to maintain operational continuity.
