Nortel NTDU27AA: CS1000/CS1000M Succession Signaling Server assembly, providing SIP and gateway signalling.

The Nortel NTDU27AA is a CS1000/CS1000M Succession Signaling Server assembly, providing SIP trunking and gateway signalling for a CS1000M Succession enterprise voice system, coordinating call setup between the PBX and IP-based trunks or endpoints.

Nortel CS1000/CS1000M and Meridian 1 systems remain in service across offices, hospitals, universities and public sector sites. Manufacturer support ended with the move to Avaya, so secondary-market assemblies are now the normal route to keeping one of these systems running. Specifiers should confirm their exact CS1000 software release before ordering.
