Marconi GPT 1HAT10236AEL access/transmission systems Telecom System Card / Module

The Marconi GPT 1HAT10236AEL is a switch controller card for Marconi’s (formerly GPT’s) access and transmission platform, providing the central switching-fabric control function within an access node shelf that coordinates traffic between the shelf’s interface and trunk cards. Marconi GPT hardware of this generation remains in service on established carrier access networks, and the switch controller is typically the single most critical card in a shelf, since its failure can take the whole shelf’s switching function down rather than just one interface. A genuine replacement controller is therefore a routine, high-priority spare for these deployments. Specifiers should confirm the exact host chassis and firmware revision before ordering. Tech-Star (UK-based, shipped worldwide) sources and tests Marconi GPT components to support legacy and current deployments alike.
