[Asterisk-Users] Unable to start D-Channel

[Lay Chi Man]

Hi all,

I have a problem on starting the ISDN PRI T1 line using on Wildcard 
T400P.It keeps saying the D-Channel of the span is down after T200 
timeup and sending SADME and receive DM from network side.

How can I start the D-Channel? I have checked with the network side and 
matched with their framing and coding.
