Adtran 1242046L1 FT1 DP Module

ADTRAN 1242046L1 FT1 DP Module is a legacy ADTRAN network interface module designed for FT1 DP configurations. The part number 1242046L1 is paired with an internal identifier shown in product listings as HI9CYCJB. This module is associated with ADTRAN's FT1 DP family, a control path used in older T1/FT1 deployments to carry data over twisted-pair facilities within channel banks and related interface cards. In reseller listings, the model is explicitly labeled as ADTRAN 1242046L1 FT1 DP Module, confirming its role as a field-replaceable component within the ADTRAN FT1 DP lineage. Technicians and network engineers who maintain legacy ADTRAN equipment may encounter this module when servicing FT1 DP circuits, where it serves as the card-level interface enabling FT1 signaling within the broader Total Access ecosystem. Typically installed in appropriate ADTRAN chassis or channel banks, these FT1 DP modules connect through standard backplane interfaces and support FT1 signaling within legacy telecom networks.
