This field is deprecated. For ISUP service profiles, specifies the type of continuity
test to perform, based on the configuration of the remote
switch or trunk connection. The remoteLoopback test is used
when the remote switch will loop back channel being tested.
The remote2Wire test is used when the remote switch supports
the 2 wire continuity test procedure. And the remote4Wire
test mode is used when the remote switch supports the 4 wire
continuity test procedure. The default value is remoteLoopback.
