TruePulse is looking for NT7H61BA and NT7H72AA for Northern Telecom’s FMT-150, or the Nortel FMT-150.  Have you recently decommissioned any FMT-150s?

The NT7H61BA, HECI code M3CSD50, is a Monitoring and Control Module for the Nortel FMT-150.  You may also be familiar with the part as a CTDI NT7H61BA.

The NT7H72AA, HECI code M3PQ003, is a Fan Module for the Nortel FMT-150.  You may also be familiar with the part as a CTDI NT7H72AA.

The FMT-150 transmits one, two or three DS-3 signals, up to 84 DS-1s and a maximum of 2016 voice circuits. Designed to interface with DS-1 input signals, the FMT-150 utilizes 150 Mb/s fiber transport plug-ins (with up to three DS-3 inputs) and offers plug-in commonality with the DMT-300.

The FMT-150’s maintenance system can be accessed multiple ways: through computer links through the RS232 remote operations port (ASCII) or RS422 remote alarm port (TBOS E2A) that provide complete, monitoring and troubleshooting capabilities, including fault sectionalization of the remote site. You can also monitor alarms and controls at local sites.

The FMT-150 offers:

  • Standard interfaces: DSX-1, DSX-3
  • Optional MX3 multiplex protection
  • Accepts a mixture of DS-1 line signals, i.e. AMI and B8ZS
  • Optional front access
  • Microprocessor controlled monitoring and diagnostics
  • Extended temperature range option
  • True hubbing capability
  • DS-1 and DS-3 remote loopback route diversity

In addition to the NT7H61BA and NT7H72AA for the FMT-150, TruePulse is interested in many Nortel optical transport platforms, such as the Connect DX, the S/DMS TransportNode OC-48 NE, the FD-565, and the Connect HDX.
