:>:Hi.
:>:I am trying to get my telco to provision my ISDN BRI line correctly for
:>:use with my ORU-UP. I used the incantation "ACO on the second B-channel"
:>
:>What do they claim ACO stands for?
:That spell was from Lucent. ACO=Additional Call Offering (I suppose the
:equalivent of Call Waiting).
Sort of, ACO is what will allow DCA (Dynamic channel allocation). That is
the ability to drop the b2 data channel IF a voice call comes in on the D
channel. DCA is a subset of PPP and is supported in Linux.
:That's what I have now. I am wanting to get the ability to have the
:ORU-AP drop the B2 call when a voice call comes in. I need ACO on that
:channel and am hoping the easiest way is to get the telco to use the
:pre-defined IOC feature sets.
Yes that is DCA which requires you order ACO. But I seem to remember reading
that there was a bug that prevented the ATT 5ESS switch from doing this
properly. I think NI-1 will do it tho.
Now.. does the OR-U's PPP implementation support DCA? The Bitsurfer Pro
supports DCA, but I cannot find any reference to DCA in the OR-U-AP specs. I
just grepped all the release notes and didnt find anything.
BACP is not yet supported in the OR-U. But I dont know if that would help.
According to the rfc 2125, in order to drop a data call to take an incoming
voice call, the receiving unit would have to receive an LCP Terminate
Request for that channel to remove the link and make it available, and I
believe those are intended to come from the other end, and not the switch
itself. Its all moot anyway since there is no BACP (publically available)
for the OR-EWE-EY-PEE.
