none(1)  - the interface is not in maintenance mode.
hostCompressedLoopback(2) - Host Compressed Loopback.
This mode is set by the managed system to perform the 
compressed voice loopback test. The voice packet is passed
by voice application to the interface associated CODEC.
Instead of feeding these into the CODEC for decompression,
they are immediately sent back to the voice application as
if they had originated locally and been compressed.
              
hostUncompressedLoopback(3) - Host Uncompressed Loopback.
This mode is set by the managed system to perform the 
uncompressed voice loopback test. The voice packet is 
sent by voice application all the way through the
interface associated CODEC and then turned around instead
of being sent to the telephony endpoint.
              
ifCompressedLoopback(4) - Interface Compressed Loopback.
This mode is set by the managed system to perform the 
interface uncompressed voice loopback test for the 
external test equipment that is connected to the voice
interface.
The voice samples are sent from the test equipment all the
way through the interface associated CODEC and then turned
around instead of being sent to voice application.
              
ifUncompressedLoopback(5) - Interface Uncompressed Loopback.
This mode is set by the managed system to perform the 
interface uncompressed voice loopback test for the
external test equipment that is connected to the voice
interface.
The voice samples are sent from the test equipment to the
interface associated CODEC. Instead of feeding the voice
samples into the CODEC for compression, they are 
immediately sent back to the telephony interface.
