The standard G.732 :

*Multiframe Aligment Signal:
*
When Timeslot 16 of the E1 frame is used for Channel Associated Signaling
purposes, Frame 0 contains information that is used by the receiver to
identify the incoming frame.  Specifically, this pattern in Timeslot 0,
Frame 0 is called the Multiframe Alignment Signal (MFAS).

                | *Bit 1* | *Bit 2* | *Bit 3* | *Bit 4* | *Bit 5* | *Bit 6*|
*Bit 7* | *Bit 8  |*
  Frame 0  | ------- | ------- | ------- | ------- | ------- | ------- |
------- | -------- |
                |    0   |    0   |    0   |    0    |   *X*    |   *Y*
|  * X*    |    *X  *  |


           X = Spare Bits, set to 1 if not used.
           Y = Yellow Alarm (Loss of*  *MultiFrame Alignment Signal)
                            (0 = Normal | 1 = Loss of MFAS)

But,  I used a analyser and I saw :

                 0000 0000  and must be 0000 1000

i need to change the bit *X*
