<div>The standard G.732 :</div>
<div> </div>
<div><u>Multiframe Aligment Signal:<br></u><br>When Timeslot 16 of the E1 frame is used for Channel Associated Signaling<br>purposes, Frame 0 contains information that is used by the receiver to<br>identify the incoming frame. Specifically, this pattern in Timeslot 0,<br>
Frame 0 is called the Multiframe Alignment Signal (MFAS).<br><br> | <strong>Bit 1</strong> | <strong>Bit 2</strong> | <strong>Bit 3</strong> | <strong>Bit 4</strong> | <strong>Bit 5</strong> | <strong>Bit 6</strong> | <strong>Bit 7</strong> | <strong>Bit 8 |</strong><br>
Frame 0 | ------- | ------- | ------- | ------- | ------- | ------- | ------- | -------- | <br> | 0 | 0 | 0 | 0 | <strong>X</strong> | <strong>Y</strong> | <strong> X</strong> | <strong>X </strong> |<br>
<br><br> X = Spare Bits, set to 1 if not used.<br> Y = Yellow Alarm (Loss of<strong> </strong>MultiFrame Alignment Signal)<br> (0 = Normal | 1 = Loss of MFAS)</div>
<div> </div>
<div>But, I used a analyser and I saw :</div>
<div> </div>
<div> 0000 0000 and must be 0000 1000</div>
<div> </div>
<div>i need to change the bit <strong>X</strong></div>
