I have a pair of point-to-point DS1s between two SX2000s that fail every night after active plane switch. Circuits work well otherwise, but require reset each morning. Another pair of P2Ps (between a 2k and a 3300) do not have this problem. Can anyone clarify the indeterminate message when doing a 'status'? Also looking for guidelines on trunk-service and digital link descriptors for msdn configurations. Thanks,

Indeterminate means there has been no activity on the circuit since the reboot/activity switch. Can you give a little more detail as to why your circuit is failing and has to be reset every night?

(Thanks for asking) They seem to be failing each morning at the Activity Switch. I set the far-end to Act Sw an hour earlier than the near-end, no effect. Sometimes reseting the CSU will bring them back, other times the entire card needs to be loaded (bus/rts doesn't do it). DTSTATS doesn't show many/any slips or bpvs.

As Alex said, Indeterminate means it has not been used yet. If you want to change it to idle, test the plid. Are there any maintenance logs?

Maintenance logs were showing a loss of sync. We found a possible mismatch in coding (formatter 1 cards only support ami/d4, right?). What functionality is lost with incorrect Inverted D channel setting in a P2P DPNSS environment? Thanks,

If it is only happening at activity switch, do you have a network sync set on both sides? I'll pull up the tech docs about the formatter 1 card later. The Inverted D channel should be set to yes.

Yes, both ends are sync'd, no problems there. The carrier is esf/b8zs and we're using the adtrans to convert to ami/d4 to the pbx. Also considering the use of Formatter II cards so we can have esf/b8zs all the way through.

OK - lets slow this down for the dumb guy ( me ) when you get into the office in the morning can you call across this circuit?

And what happens when you make a call across the circuit, whats on the display and what shows up in the logs after the call is made?

Are your controllers redundant on both PBX's ?

I am under the impression your circuit is not going down after the activity switch.

Trunk status is "Not Seizable". Call reroutes to 2nd choice (another formatter I card connected to a 3300 LX acting as a gateway across a 3gb link - no problems there). Yes, both 2k controllers are redundant. Circuit remains error-free (checking dts on regular basis) until the activity switch. Far-end activity switch occurs at 0115, near end at 0215. CSU reports frame-slips toward the CPE side, clear to the network.

What do the logs show on both switches and what time does the span go down? We need to see if it is the near side, far side or both activity switches. You may want to set the activity switch on both to Monday morning only for a while and see if it still happens without the switch.
