Alcatel-Lucent BBG9 SNC5670DAB OHCTL Telecommunication Module

The BBG9 SNC5670DAB OHCTL Telecommunication Module Circuit Board is an OHCTL circuit pack used in Alcatel-Lucent’s DDM-2000 OC-3 Multiplexer family. It provides the TL1/X.25 interface to operations support systems (OSS) such as Telcordia, enabling TL1-based management and X.25 sessions for remote configuration, fault reporting, and performance monitoring of OC-3 transport paths. As a plug-in circuit pack described as BBG9 OHCTL, it integrates with the DDM-2000 shelf to deliver control and telemetry functions within the OC-3 multiplexing environment. The BBG9 OHCTL card designation within the SNC5670DAB family identifies this module as the hardware component responsible for management-plane connectivity between the multiplexing platform and OSS infrastructures. In typical carrier deployments, this module supports centralized management workflows by enabling TL1 transactions and X.25 data sessions needed for fault isolation, performance analysis, and provisioning tasks across OC-3 links.
