We recently received these four Nortel NTLX44AA into stock. The NTLX44AA is a sync card for the Nortel, or really now Genband MG-4000 /Media Gateway-4000.

Used in conjunction with the DMS switch, the MG4000 spans TDM and ATM domains by accepting TDM trunk signaling and translating the output into ATM formats. The TDM-to-packet gateway can reduce tandem/transit trunking congestion and help lower network operating costs. This gateway uses open system interfaces, offering both high-speed (OC-3/STS-1) and low-speed (DS-1) access, with an OC-3c interface to the ATM switching fabric.

Sorry, but these NTLX44AA are sold. We are trying to get some more. If you need some, let us know as soon as possible.
