If SignalType=3D t= imeout is specified in the message then default type OnOff is overridden. In your case MG should apply the signal with timeout of Duration=3D15. In section 7.1.11 of H248.1 If a signal of default type other than TO has its type overridden to type T= O in the Signals Descriptor, the duration parameter must be present. -Arindam From: [email protected] [mailto:[email protected]] On Behalf Of= Murugesh Govindaraju Sent: Tuesday, September 03, 2013 6:14 AM To: [email protected] Cc: Ramesh Kuppili Subject: [Megaco] Question on using signal parameters for stimal/stedsig si= gnal Hi All, Stimulus analogue line package (H.248.34) has a signal "Steady Signal" defi= ned 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 si= gnal parameters signalType and Duration: MEGACO/1 Transaction =3D 387699 {Context =3D 48 { Modify =3D AL3{Media{LocalControl { Mode =3D SendReceive }}, Signals { stimal/stedsig { SignalType =3D timeOut, Duration =3D 15, sig =3D reversePolarity } }, Events =3D 2527 { al/on, al/of, al/fl } } } } Here is my question: Though the signal definition in package says that the steady signal is of t= ype "OnOff", but the switch says as "timeOut" and duration as not applicati= on, but the switch says as "15" sec. What should be the behavior of the MG in this case? -- Thanks, Murugesh G --_000_7DE39EC55B99FC47A3DEB6179256D99176F44D0CUS70UWXCHMBA01z_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Dus-ascii"= > <meta name=3D"Generator" content=3D"Microsoft Word 12 (filtered medium)"> <style><!-- /* Font Definitions */ @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4;} @font-face {font-family:Tahoma; panose-1:2 11 6 4 3 5 4 4 2 4;} @font-face {font-family:"Trebuchet MS"; panose-1:2 11 6 3 2 2 2 2 2 4;} @font-face {font-family:Consolas; panose-1:2 11 6 9 2 2 4 3 2 4;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0in; margin-bottom:.0001pt; font-size:12.0pt; font-family:"Times New Roman","serif"; color:black;} a:link, span.MsoHyperlink {mso-style-priority:99; color:blue; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {mso-style-priority:99; color:purple; text-decoration:underline;} pre {mso-style-priority:99; mso-style-link:"HTML Preformatted Char"; margin:0in; margin-bottom:.0001pt; font-size:10.0pt; font-family:"Courier New"; color:black;} span.HTMLPreformattedChar {mso-style-name:"HTML Preformatted Char"; mso-style-priority:99; mso-style-link:"HTML Preformatted"; font-family:Consolas; color:black;} span.EmailStyle19 {mso-style-type:personal-reply; font-family:"Trebuchet MS","sans-serif"; color:#1F497D;} .MsoChpDefault {mso-style-type:export-only; font-size:10.0pt;} @page WordSection1 {size:8.5in 11.0in; margin:1.0in 1.0in 1.0in 1.0in;} div.WordSection1 {page:WordSection1;} --></style><!--[if gte mso 9]><xml> <o:shapedefaults v:ext=3D"edit" spidmax=3D"1026" /> </xml><![endif]--><!--[if gte mso 9]><xml> <o:shapelayout v:ext=3D"edit"> <o:idmap v:ext=3D"edit" data=3D"1" /> </o:shapelayout></xml><![endif]--> </head> <body bgcolor=3D"white" lang=3D"EN-US" link=3D"blue" vlink=3D"purple"> <div class=3D"WordSection1"> <p class=3D"MsoNormal"><span style=3D"font-size:11.0pt;font-family:"Tr= ebuchet MS","sans-serif";color:#1F497D">Hi Murugesh,<o:p></o= :p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:11.0pt;font-family:"Tr= ebuchet MS","sans-serif";color:#1F497D"><o:p> </o:p></s= pan></p> <p class=3D"MsoNormal"><span style=3D"font-size:11.0pt;font-family:"Tr= ebuchet MS","sans-serif";color:#1F497D">Signal Type: OnOff i= s default type in the specification.
