[Resolved] PRI SABME question

Asterisk Asterisk Support

D-channel is going up and down all the time. I was checking it on two different hardware (2xmotherbord and 2xwildcard) but on the same disc.
When I type pri debug span 1 I get

-- Got SABME from network peer. Sending Unnumbered Acknowledgement q921.c:782 q921_reset: q921_state now is Q921_LINK_CONNECTION_RELEASED q921.c:733 q921_dchannel_up: q921_state now is Q921_LINK_CONNECTION_ESTABLISHED -- Got SABME from network peer.

What does this output mean? What may be the cause of that? How can I fix that?

What T1 card are you using?

I’m using TE205P in E1 mode.

Edit /etc/zaptel.conf

Change this line:
dchan=16

To this:
hardhdlc=16

Do this for both spans if used of course using the correct channel.

Thanks.
Problem resolved.

Was it resolved by using hardhdlc?
