[asterisk-users] Primary D-Channel on span 2 down

[Eugeniy Khvastunov]

Hello All!

At start of an asterisk I see the following:

  == Primary D-Channel on span 2 up
  == Primary D-Channel on span 2 down
Oct 23 10:26:25 WARNING[9515]: chan_zap.c:2287 pri_find_dchan: No 
D-channels available!  Using Primary channel 47 as D-channel anyway!
  == Primary D-Channel on span 2 up
  == Primary D-Channel on span 2 up
  == Primary D-Channel on span 2 up
  == Primary D-Channel on span 2 up
.....

What can be to it the reason?
