The Nortel NT6X70BA is a Continuity Tone Detector (CTD) circuit pack used in Nortel DMS digital switching systems. Nortel’s DMS-100 Family Quick Reference Guide identifies NT6X70BA specifically as “Continuity Tone Det (MD)”, indicating a maintenance-discontinued version of the NT6X70 circuit pack family.
The NT6X70 family detects tones used during call processing to verify continuity of the voice/data path between Line Trunk Controllers (LTCs). It monitors and records the frequency and level of detected tones, with the information retained for use by the XPM processor.
