I have tried all kinds of DSP cards .49 .51 and .53 At this point, I am suspecting ospf being the cause of this since Marshall Morgan says he does not see this behaviour on a non ospf hiperarc setup. If anyone is running ospf without any problems, let me know so I don't start converting to RIP for nothing. One other observation: - Once a channel is stuck in LocalOutOfService, any further call beyond that channel on the PRI gives a fast busy signal Donald

I am trying to move to the 5.x.x Hiper Arc code branch but for some reason The DSP's running in the same chassis start to show Local Out Of Service on one or two channels after a few days of service. The chassis is configured as a regular IP only dial-in service.
Here are my observations: - The issue happens with all recent DSP codes (up to 2.1.9) - The issue happens with all Hiper ARC 5.x.x (up to 5.1.99-8 including 5.0.x) - The issue does NOT happen with Hiper Arc 4.2.x (up to 4.2.78) - The issue happened with DMS100 and 5ESS switches connected to the DSPs - I am running PRI with no NFAS (i.e 23 channels + D channel) - The issue does NOT affect the PRI T1/E1 Quad Modems - I tried NMC and HiperNMC without any difference - In all my tests I was running ospf - I have tried 64Megs and 128Megs HiperArc cards - I made sure to enable ppp offloading - the issue happens with chassis of 2 DSP's up to 10 DSPs
When the problem happens I get the Service state 8 on TCM. If I busy/Unbusy the DSP card the channels lock out and show a "Remote Out Of Service" message and the PRI channels can nolonger be busied/unbusied until I reboot the DSP card. I usually also reboot the HiperArc just in case.
I refuse to think that this is related to telco because I have been able to repeat the issue with two different PRI providers with two different switches. And the issue happens only with HiperArc 5.x.x (never with 4.2.x)
