8DG62548AB Ericsson Nokia 1830 PSS System Module

The Ericsson 8DG62548AB is a PBA 130SCUPC (Printed Board Assembly System Control Unit with PC interface), a critical control and management board designed for optical transport network equipment. This board provides centralised system control, monitoring and management functions within telecommunications infrastructure platforms.

The 130SCUPC serves as the primary control processor for optical network systems, handling equipment supervision, alarm management, configuration control and communication interfaces. It is typically deployed in optical transport network (OTN) and synchronous digital hierarchy (SDH) equipment where reliable system management is essential.

This component originates from the Nokia/Alcatel-Lucent optical networking portfolio, which Ericsson has supported through various technology partnerships and acquisitions. The board is suited for operators maintaining existing optical transport deployments or requiring spare components for network continuity.
