Subject: [Megaco] Question on using signal parameters for stimal/stedsig signal

Stimulus analogue line package (H.248.34) has a signal "Steady Signal" 
defined in it.

Following is the definition of this signal from this package:
*6.3.2 Steady Signal**
**Signal name: Steady Signal**
**Signal ID: stedsig (0x0002)**
**Description: Used by the MGC to instruct the MG to apply a steady 
signal.**
**Signal Type: OnOff**
**Duration: not applicable*

This signal has only one parameter called "sig".

What if we receive the following request from switch, which contains the 
signal parameters signalType and Duration:

MEGACO/1 Transaction = 387699 {Context = 48 {
     Modify = AL3{Media{LocalControl {   Mode = SendReceive
         }},
       Signals {
         stimal/stedsig {
           *SignalType = timeOut,
           Duration = 15,*
           sig = reversePolarity
         }
       },
       Events = 2527 {
         al/on,
         al/of,
         al/fl
       }
     }
   }
}

Here is my question:
Though the signal definition in package says that the steady signal is 
of type *"OnOf**f"*, but the switch says as "*timeOut*" and duration as 
not application, but the switch says as "15" sec.
What should be the behavior of the MG in this case?
