This object specifies the maximum hold-time for this SXP
connection when the device is acting as 'listener'.
Value of this object must be greater than
ctsxSxpConnListenerMinHoldTime.
Setting the object to zero indicates that the global value
ctsxSxpListenerMaxHoldTime will be used for the connection.
Value of this object must be zero if the corresponding
instance value of ctsxSxpConnListenerMinHoldTime is zero.
Setting the object to 65535 indicates that hold-time
functionality has been disabled for the connection. Value of
this object must be 65535 if the corresponding instance value
ctsxSxpConnListenerMinHoldTime is 65535.
Value of this object should be ignored and can not be set
if the corresponding instance value of ctsxSxpConnModeLocation
is 'local' and ctsSxpConnMode is 'speaker' or
ctsxSxpConnModeLocation is 'peer' and ctsSxpConnMode is
'listener'.
