Adtran 1223004L6 Remote Telecommunication Transceiver Card

The Adtran 1223004L6 is an H2TUC remote transceiver card from ADTRAN, designed for use in H2TUC-based remote shelf configurations to terminate and manage HDSL2 digital links, enabling the remote interface that feeds copper-line services into the network. Within the 122300xL6 family, which also includes 1223001L6 and 1223003L6, this module functions as the remote half of a high-speed transceiver pair, interfacing with central-office equipment to carry data over copper lines and support basic monitoring and alignment tasks in the field. Documentation linked to these cards references TScan technology, a splice-detection capability used to monitor integrity and detect anomalies in ADTRAN deployments, reinforcing the card’s role in ensuring reliable remote links. The 1223004L6 designation identifies this remote transceiver card as part of ADTRAN’s H2TUC hardware lineup used in legacy HDSL2 remote configurations, serving as the remote-side partner to central transceivers in the ADTRAN ecosystem.
