Function name: 
Loopback Test 
Function description: 
The GSM Series switches support two types of loopback tests including an Internal and 
an External loopback test. The internal loopback test is an internal test and no test signal 
is sent out of the switch. The external loopback test will send the test signal to its link 
partner to check if the port has got an active link. If there is no active link the external 
loopback test will fail.
