TruePulse is looking to purchase NT1X68AB and NT1X80AA circuit packs for the Nortel DMS-100.

The NT1X68AB, HECI code ENPQN1J or NT1X68AC, HECI code ENPQN9X are Nine Track Tape Controllers.  The magnetic tape controller card contains the logic to provide an interface for one MTD (Magnetic Tape Drive), always on port 0 at the MAP (Maintenance & Administration Position) display. It connects a read cable, a write cable, and a control cable, using ports 1, 2 and 3 respectively. Port 0 is always unequipped.  You may possibly be familiar with the modules as a Genband NT1X68AB and Genband NT1X68AC.

The NT1X80AA, HECI code ENPQAL6, is an EDRAM card.  The enhanced digital recorded announcement machine card (EDRAM) provides voice messages to the user. The NT1X80AA provides 4.3 minutes of announcement time and 30 announcement channels. The NT1X80AA is positioned as a peripheral module (PM) to the DMS digital trunk module (DTM). The card is located in a provisional trunk slot of the maintenance trunk module (MTM), the services trunk module (STM), or the integrated services module (ISM). The card has its own DS30 link and is connected to the network by means of a direct cable.  You may possibly be familiar with the modules as a Genband NT1X80AA.

Ribbon Communications no longer supports the DMS-100.

In addition to the NT1X68AB and NT1X80AA, TruePulse is also interested in other DMS-100 modules.  But we are interested in modules for other Nortel platforms including the Connect DX, the OME 6500, the S/DMS TransportNode OC-3/OC-12 and the OM 3500.
