Nortel NTDU27AA 04 (telecommunications transmission and networking portfolio) Telecom System Card / Module Image 1

The Nortel NTDU27AA (release 04) is a Signaling Server for the Nortel Communication Server 1000 (CS1000) platform, part of the established NTDU card family.

The Nortel NTDU27AA is a Signaling Server for the Nortel Communication Server 1000 (CS1000) platform, part of the documented NTDU-prefixed card family used across Nortel’s Succession/CS1000 IP telephony system; this unit carries release suffix 04. The Signaling Server handles SIP and H.323 call signalling, gateway control and a range of CS1000 applications separately from the Call Server itself, letting a CS1000 system scale its signalling capacity independently of core call processing. CS1000 systems remain widely deployed, and genuine Signaling Server hardware is a routine requirement for maintaining redundancy or restoring service after a unit failure; the release level fitted should be confirmed against your system’s software load before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel CS1000 hardware to support ongoing system maintenance. Please contact our sales team to confirm exact compatibility of the Nortel NTDU27AA 04 and for current stock and pricing.
