Nortel NTBK45AB (OPTera Metro / PDH-SDH / Passport-MSS / networking portfolio) Telecom System Card / Module

The Nortel NTBK45AB is described on our supplier record as a system core card. In Nortel PBX terms the system core carries the call processor and the core software load, so it is the card the rest of the system depends on, but our record does not name the option or generation it was built for. 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.

Nortel Meridian 1 and CS1000 systems remain in service across offices, hospitals, universities and public sector sites. Manufacturer support ended with the move to Avaya, so tested secondary market cards are now the normal route to keeping one of these switches alive.

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.
