[asterisk-users] Digium PRI card hi-Z for sniffing?
Does anyone know if the Digium PRI cards can be configured or modified to have a high-impedance input on the RX pair? I would be interested in this in order to build a bi-directional PRI audio sniffer using two E1/T1 ports per trunk to be monitored.

I looked in to this exact thing several years ago, and while I do believe that the hardware is capable of it (I don't have a card in front of me, but I believe the T1 termination is done inside the QuadFALC), the driver does not have this capability. I don't think it would be impossible to add, but it would take some work, and please keep in mind that this was a number of years ago that I did look at this on the TE405P, so my memory may be a little hazy. -A. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Hi Tony, http://www.voicetronix.com.au/openpri.htm Never tested, though. We used the analogue boards for monitoring, so far.

We used the analogue boards for monitoring, so far. Thanks for the link - looks interesting. Still interested in whether Digium cards can be set to hi-Z if anyone knows.

I talked to the product manager over the hardware cards yesterday, and he said he wasn't aware of any support on our cards for doing that. I've always seen it done in an external box that sits between the telco and the digital card. -- Jared Smith Training Manager Digium, Inc. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
