Industrial NTDK27AA Ethernet Adapter Cable Assembly

The Industrial NTDK27AA Ethernet Adapter Cable Assembly is a legacy Nortel Networks Ethernet interface adapter that provides Ethernet connectivity for Nortel Meridian and Option series PBX and switching systems. This external cable uses a DB25 male to DB15 female connector and measures about 6 ft (1.8 m) in length, designed for installation in central offices, telecommunications equipment rooms, or maintenance terminals where Ethernet access is needed for programming, diagnostics, and network communication. Manufactured by Nortel Networks / Northern Telecom, the part carries MPN NTDK27AA (alternate A0630723; secondary marking 143-1) and is commonly used as a repair or replacement component for Meridian and Option systems, available primarily through surplus channels.
