I got questions, were you guys upgrading to 5.0 on Option 11C (NTAK11 Cabinet)replacing MGC card with NTDW60ABE5 the new CPU all ethernet connections?
Background:
Nortel is placing all Upgrades and Installs on Hold for Meridian 1 PBX 11C, Cabinet CS 1000M Cabinet (NTAK11) to
release 5.0W where the SSC Card (NTDK20) is being replaced with a CPPM (NTDW61) Processor Card and a MGC
card (NTDW60) or being newly installed.
Nortel is currently investigating an issue that can result in DTA002 events along with Noise and Clicking that is being
experienced when the system has the CPPM and MGC card installed at 5.00W .
This affects only the Option 11 Cabinet based systems with CPPM/MGC IP enabled.
This does not apply to Option 11 Cabinet based TDM systems on 5.0W.
Analysis:
Testing has determined that the MGC card causes noise on the back plane due to clock loading.
We got a New part number (NTDW60BBE5) which should fix the issue.
