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*
