Plays a pair to open falls the line

I am play west the boast to tour, recently did not know any reason, I double opened the boast, had a number to fall the line, but did not demonstrate the network interrupt, will have fallen.In addition a number is very normal, does not have the card machine not to fall the line.
Before simply has not had this kind of situation, I am the net pass.
Before I pay attention looked that under me that transmits how many bytes, received how many bytes to achieve 100,000,000
Now only then more than 200 ten thousand bytes,
How looks under the master explanation a matter.
Now allows double to open?
