(usr-tc) Local Out of Service on 5.x.x HARC branch
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) Donald - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Hello.. Hei thanks for the help before.., really change my internal ip network, and now my Tc is working in a ip pool, without problem.. But i have a new question.... Okss.. Sometime ago, i hemember see in 3com something about the Update the TC v34 analog modems to 56k. ( long long time ago, beta version i think).. but now i cant see thiss... A lot of peoples say to me, that only digital modems have or user the v90 x2 protocol.. but i have couriers modem from 3com, analog 56k v90 and x2.. ( humm i think that in TC use modems like courier....and to TC modempool have this update..) why the Netserver no? How i do this?? Pleasee. some help?? thankss - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Hi If you want to support x2/v90 then you must have an x2 enable key in your netserver card. If you dont have one you will have to buy one, try this link To Join: mailto:join-isp-equipment@isp-equipment.com It will work with either the digital modems or the digital/analog modems. I don't think it will work with the analog only modems, I have never even seen a analog only modem. Also for the v90 to work you must have a T-1 card in the t/c box and you t-1 line must be connected to the digital side of your local Centeral office, A line side connection will not work... I hope this helps - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I just found one of my channels in this state, it was channel 1 of a .49 hardware, 2.1.9 software card. -- Aaron Nabil - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

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 find it hard to believe that much of anything on the Arc could be causing channels to be going to LocalOutOfService. Do you have any autoresponse stuff set up on the NMC? That's the only thing I can think of there.
One other observation: - Once a channel is stuck in LocalOutOfService, any further call beyond that channel on the PRI gives a fast busy signal
Sounds like you're running NI-2 translation on it. NI-2 doesn't have service message, so the switch doesn't know the channel is LocalOutOfService, so it keeps sending calls down that channel. The DSP does the only thing it knows to do and rejects the call resulting in the fast busy. Switch to a custom-5ESS or custom-DMS100 (or whatever switch type your telco has) and you should be able to get service messages and get the behaviour you're expecting here (LocalOutOfService channels get skipped) -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Hello, - I have tried several NMCs (including HiperNMC) none of them had anything customised other than the snmp community strings. BTW, I do have chassis awareness enabled on the HARC. - I had suspected in the past an NI-2 issue but how do you explain that when I "manually" busy out a channel, the switch skips the channel correctly ? It is only when the DSP locks into LOOS that I get a fast busy. - One thing I forgot to mention is that some dial-in users (very few) get a Radius Attribute of Tunnel-Server-Endpoint. In other words, the HiperArc is acting as a LAC for an L2TP tunnel. This is probably unrelated but at this point I am suspecting anything... - One of 3com tech support did acknowledge the issue a while ago, he sent me a special HARC code (5.0.81) but it did not fix the problem. He suggested I go back to 4.2.73 I'm just curious on what exactly is causing this behaviour Donald
