New Revision: 7053

URL: http://svn.asterisk.org/svn-view/dahdi?view=rev&rev=7053
Log:
qfalc v3.1 now has integrated xmit resistors.  The external resistors connected
to XL1 and XL2 pins are now replaced with 0ohm resistors.  Now we program
PC6.TSRE to switch between 2ohms for T1 and 7.5ohms for E1 mode.
