NTBX34BC and NTBX34CA

TruePulse is looking to purchase NTBX34BC and NTBX34CA for the Nortel DMS-100.

The NTBX34BC, HECI code ENPQAWX / ENPQAWX1AA, is a Nortel DMS-100 LCME Processor Circuit Board.  The NTBX34BC, or more fully, the ISDN enhanced LCME processor circuit board works as a link between the ISDN extended peripheral modules (XPM) and the line drawers. The NTBX34BC circuit card performs the processing for scanning of line cards for calls, the initiation of call connections through the Digroup Controller Card (DCC), and the handling of DMS-X messages. 

The NTBX34CA, is a Nortel DMS-100 SRU ISDN LCM Processor Circuit Board.  The NTBX34CA, or more fully, the ISDN enhanced line concentrating module (LCME) has identical hardware to the NTBX34BA and NTBX34AB with different firmware. The NTBX34CA works at the link between the ISDN extended peripheral modules (XPM) and the line drawers. Similar to the NTBX34BC above, the NTBX34CA performs the processing for scanning of line cards for calls, the initiation of call connections through the Digroup Controller Card (DCC), and the handling of DMS-X messages.  But the NTBX34CA starts the PCM30/DS1 links to the host on power-up in the Small Remote Unit (SRU).

You may alternately be familiar with the NTBX34BC or NTBX34CA under the Genband or Ribbon Communications brands. 

Beyond just the NTBX34BC and NTBX34CA, TruePulse buys and sells many other DMS-100 modules.  We are also involved with numerous other Nortel platforms including the OM 6500, CPL, the OM 5200 and the OM 3500.
