AT&T ED8C724-30 OC-3 Shelf Assembly Component

ED8C724-30 OC-3 Shelf Assembly, G3, is a DDM-2000 OC-3 shelf component used in Lucent/Alcatel‑Lucent telecom installations to terminate OC-3 traffic within a DDM-2000 chassis. The shelf provides 8.5 inches of mounting space and accepts compatible interface modules (sold separately) that realize DS1, DS3, EC-1, OC-1, and OC-3 interfaces. The ED8C724-30 designation identifies the specific shelf revision, designed for OC-3 configurations and compatible with other ED8C724-30 family variants such as G1 and G4. As a core component of the OC-3 multiplexing shelf, this assembly serves as the physical backbone for card modules that carry line-rate traffic, with the shelf itself housing the backplane and mechanical connections required for reliable operation in telecom environments. When ordering, pair this shelf with the appropriate OC-3/OC-1 interface modules and ensure compatibility with the DDM-2000 OC-3 system chassis to support your network topology and traffic requirements.
