Nokia C108900 B1B: 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 is UK-based and ships worldwide. Get in touch to confirm compatibility with your Nokia system.
