Nortel NTEP21AB (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTEP21AB is recorded as a 13 V35 TP item. That reads as the termination panel for a thirteen circuit V.35 interface card: the breakout assembly that presents the connectors the station cabling plugs into, rather than the processing card itself. Beyond that designation our record is silent, and the release the unit carries needs confirming against the item itself rather than assumed from the code.

DPN-100 and the Passport family were Nortel’s packet and multiservice switching platforms, carrying X.25, frame relay, ATM and later IP services for carriers and large enterprises. A node is assembled from function processors, each pairing a processor with the physical interface for one service type, plus control processors and the shelf that carries them.

If you can tell us the system this is going into, or send a photograph of the board label, we will check the unit we hold against your requirement before you order. Tech-Star (UK-based, shipped worldwide) sources and supplies Nortel hardware to order. Get in touch with our sales team for availability, tested condition and a price.
