Wow you're the first person I've seen using a combination of T1 and E1 on the same card. I wonder if this has something to do with it (i.e. a bug in the drivers).

Based on my understanding of these cards, I don't think it's possible for this to work.


The framer chip on the board will sync itself to the incoming streams and recover the data, so that _might_ work. What will _not_ work properly is the outgoing streams; all the streams leaving the card are clocked using the same clock (either the on-board clock, or the currently selected "span" clock).

When you set a span to clock source "1" in zaptel.conf, that makes it the preferred transmission clock source for the _entire card_. If that span is down, the span marked "2" becomes the source for the card. If none of the spans with non-zero preferences are up, the card uses its internal source to clock the transmissions.
