[Asterisk-bsd] No D-channels available! on T100P

[Brad Waite]

Hi all,

I'm having problems turning up a single span PRI with my T100P.  I'm
getting the following errors on the console:

  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 down

D-channels available!  Using Primary channel 24 as D-channel anyway!

Any ideas?  I've double-checked the signalling and framing and D-channel. 
I've even had the telco (XO) try 5ess signalling.  I've also (blindly)
attempted various settings with the following zapata.conf options:

;pridialplan=national
;prilocaldialplan=national
;priindication=inband
;priexclusive=yes
;nfs=none
