Huawei CB03DSL0 C&C08 PBX Card / Module

The Huawei CB03DSL0 is a digital subscriber interface board used within the Huawei C&C08 digital switching platform, a legacy carrier-class telephone exchange system widely deployed for PSTN voice switching. The board provides subscriber line interface capacity on the C&C08 switch, connecting subscriber lines back into the switching fabric so that calls can be set up, routed and billed by the exchange. It is listed in Huawei parts documentation alongside other C&C08 subscriber and trunk boards such as the CC08ASL and associated PDU/control boards, confirming it as a genuine board within this switch family. C&C08 exchanges remain in service in many networks that have not yet fully migrated to IP-based switching, and operators maintaining these installations continue to need spares and replacement line cards such as the CB03DSL0 to keep existing subscriber capacity in service. As a card designed for a specific legacy switch platform, it is not interchangeable with boards from other Huawei product lines.
