Hi, With a digium dual PRI card (dual span). Is there any reason I can't have both PRIs being PRIMARY timing sources? They are both from different CLECs, and as such I need them both to do their own timing.

Now you may be in luck, because even from different CLECs, the clocking tree SHOULD come back to the same clock on their ends, so just choose one as a primary, the other as a secondary (if the primary fails) and you SHOULD be good to go. If they do not have the same clock source you'll end up with frame slips and HDLC errors... in which case there isn't much you can do unless you use either two separate TE110P cards (meaning double the interrupt rate, etc.) or go with a Sangoma dual-span card, which does support this. -A.

In general the PSTN is all synced up these days. Steve
