Nortel NTAK79AA (OPTera Metro / PDH-SDH / Passport-MSS / networking portfolio) Telecom System Card / Module

The Nortel NTAK79AA is identified on our supplier record as a 2 Mbit/s PRI card. A 2 Mbit/s primary rate interface terminates a 30 channel ISDN circuit on the PBX, which is the standard European trunk connection between a switch and the public network or another site. We have taken that description straight from the supplier record rather than inferring a specification around it, so the host system is worth confirming before you order.

Meridian 1 is Nortel’s large enterprise PBX family, later continued as Communication Server 1000. A system is built from common equipment, network and peripheral shelves, with intelligent peripheral equipment cards providing the line, trunk and service circuits. A great many are still in daily use, and they are maintained by replacing individual cards.

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 is UK-based and ships worldwide. Contact our sales team for current stock, condition details and pricing on this Nortel part.
