[svn-commits] rmeyerriecks: branch linux/rmeyerriecks/dahdi-linux-alarms r8840 - in /linux/...

[SVN commits to the Digium repositories]

Author: rmeyerriecks

New Revision: 8840

URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=8840
Log:
Added hardware transformer check

QuadFalc has the ability to test if the transformer is
performing correctly. If the components between the framer
and the physical span interface are shorted out or opened
for any reason we can now detect it. Possible causes for
tripping this error could be a broken transformer from
an electrical spike or a board manufacturing error.
