Nokia ESB20-A shelf/bus support unit for Nokia SDH/PDH multiplexer platforms.

The Nokia C108900 B1B is an ESB20-A card, a shelf/bus support unit from Nokia’s legacy telecom equipment range. Units in the ESB family provide backplane or bus-support functions for the shelf they’re fitted to, working alongside the interface, control and power cards installed in the same rack.

As a support-tier card rather than a customer-facing interface or a control processor, the ESB20-A’s role is to keep the shelf’s internal bus and inter-card communication functioning correctly, rather than terminating an external circuit directly.

Please confirm shelf type and slot compatibility before ordering. Tech-Star (UK-based, shipped worldwide) checks every module before it ships. Get in touch to confirm compatibility with your Nokia system.

Worldwide supply. We export new and refurbished telecoms and networking equipment internationally. International buyers welcome, request a delivered quote in your currency. Supply subject to export checks.
