You are correct; if the spans are on different cards, then one of them would ideally be configured to use the clock recovered from the span, instead of its own onboard clock source. However, even if both cards are configured to use their own clock sources, if those clocks are close enough in frequency and don't have appreciable jitter, the system would still work just fine. It's not an optimal configuration, though. I don't know that I know what you mean by 'set timing'; if you transmit a bitstream onto a T1/E1 span, that bitstream includes clocking, by definition. The source of that clocking is what we are talking about, not whether it is present or not. -- Kevin P.
