connection when the device is acting as 'speaker'.
Setting the object to zero indicates that the global value
ctsxSxpSpeakerMinHoldTime will be used for the connection.

of ctsxSxpConnListenerMinHoldTime is 65535.
Value of this object should be ignored and can not be set
if the corresponding instance values of ctsxSxpConnModeLocation
is 'local' and ctsSxpConnMode is 'listener' or
ctsxSxpConnModeLocation is 'peer' and ctsSxpConnMode is
'speaker'.
