TruePulse would like to acquire NT7X05CA and NT9X10CA for the Nortel DMS-100.

NT7X05CA, HECI code ENCEAFA, is a PERIPH REC LDR for a Nortel DMS-100.  Perhaps more clear is that it is an XPM (XMS-based Peripheral Module) Flash EEPROM Pack.  You may also be familiar with the unit as a Genband NT7X05CA.

NT9X10CA, HECI code ENI2BBB, is a 60Mhz BRISC for Series 70 SN for the Nortel DMS-100.  You may also be familiar with the unit as a Genband NT9X10CA.The NT9X10CA Series 70/EM60 BNR reduced instruction set computer (BRISC) CPU card provides increased performance over the NT9X10AA CPU. It also maintains Series 70 performance for large software loads. The NT9X10CA CPU card can replace the Series 50/60/70 BRISC CPU and the NT9X13 cards. The NT9X10CA card also requires the replacement of the RTIF cards with the NT9X26GA card.

The NT9X10CA processor card, the NT9X26GA RTIF card, and the optional NT9X14FA memory card are designed to be used together. The NT9X10CA CPU card functions only with the NT9X26GA RTIF paddle board and the optional NT9X14FA extended memory card. 

The Nortel DMS-100 is a Class 5 voice switch, which provides telephone service to customers, and as such is concerned with “subscriber type” activities: generation of dial-tone; handling of network services such as advice of duration and charge.

Genband, now Ribbon Communications, no longer supports the DMS-100.

In addition to the NT7X05CA and NT9X10CA, we are interested in other Nortel DMS-100 circuit packs.  Furthermore, we are looking for circuit packs for other Nortel platforms, such as the Optera Connect DX, OME 6500, S/DMS TransportNode OC-48 NE and the OM 3500.  We are your Nortel central office equipment specialist!
