Test Call
Extension
The extension used to set up a DSO loop around connection for
testing non-ISDN DS1 trunks. The DSO Loop-Around Test Call
feature is used primarily for testing DSO channels associated

the test extension number; multiple DSO Loop-Around
connections can be established by placing multiple calls to the
loop-around extension.
