The Nortel NT6X70AA is a DMS-200 Continuity Tone Detector card, confirming end-to-end trunk continuity before a call is allowed to proceed. It occupies one position within a Digital Trunk Controller (DTC) shelf on the Nortel DMS-200 toll/tandem switching platform, where it verifies the transmission path on inter-office trunks meets loop-continuity requirements ahead of call setup, a standard safeguard on large carrier switches to stop calls being routed over a faulty circuit. DMS-200 exchanges of this generation remain in service on a number of established carrier and tandem networks, and genuine spares such as this one are a routine requirement for maintaining full trunk capacity or replacing a failed detector card. Tech-Star (UK-based, shipped worldwide) stocks Nortel DMS-200 cards to support ongoing exchange maintenance.
