New Revision: 9517

URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=9517
Log:
dahdi_maint: Added the loopup/loopdown functionality

Put back in the loopup and loopdown functionality which had been removed
from dahdi_tool

According to the spec AT&T TR 54016 we should keep the loopback
actuate and release signals on the line for 5 seconds.
