Hi all, Has anyone used MSPPP Encryption on an ARC? I'm trying to configure the ARC (Firmware ver. 5.3.3 - 168bit encryption enabled) to work together with SteelBelted Radius ver.3 to get any user who connects to the TC to connect with MicroSoft PPP 128bit data encryption. I've set the attributes in the user tab of SBR for MSPPP Encryption required and 128bit and also defined 128bit_Microsoft_Encryption as the encryption algo. on the default user on the ARC. But this doesn't work. Any help is more then welcomed Thanks Gilad Shinman Network Engineer Intel Israel gilad.shinman@intel.com 972-4-8655577
Hello & Help. :-) On Friday night, we had a pretty good lightning storm here, and about 12:30 AM, our T1 connected to our 3COM HiperDSP stopped taking calls. The power had been out for a few minutes longer than our UPS's can handle, so some of the servers had reset and some hadn't, depending on the particular UPS. I had initially thought the settings in the DSP had been corrupted in the process so that it wouldn't answer (it was answering with dead air) but when we plugged the T1 into our old backup equipment, it only had 4 active channels out of 24 (and it wasn't connected or on at the time of the storm) so we then figured the culprit was upstream. We unplugged the 4 wires from our Pairgain HDSL T1 box to shut the power off to it and then reconnected them, and our old equipment started taking 24 calls again. Good deal - fixed... Or not. When we plugged the T1 back into the HiperDSP, the green CAR light does not come on and only the red ALARM light is lit. Calls no longer get dead air, they simply get routed past the card and are answered by the next modem pool (our BRI ISDN modem pool) so the entire T1 is ignored and bypassed, the same as if it isn't plugged into anything at all. So, I'm looking for suggestions / help. The Pairgain HDSL box doesn't seem any worse for the wear after the power reset, so I don't see how a lightning strike would hurt anything past it. The HiperDSP seems to check out otherwise & I can talk to it OK. I have two HiperDSP cards, but I've never had the second card configured, since I've never had a second T1 and I'm not certain it works at all (it has two red lights lit - ALM and LPBK/D-ALM). So... Help, please. Any suggestions or ideas to try would be great. I'm in Canada, so buying another HiperDSP set is not a cheap / quick thing to do. Perhaps there is an idea of something we can try that will better diagnose the problem? Todd Chamberlain
In regards to the red alarm light: The DSP may have lost it's config. Highlight the span portion in TCM and click on Configure...Programmed Settings....Trunk Settings. Make sure your span settings are correct. You may want to take a quick look under NFAS settings and make sure it is set to FAS. Carrier light needs to be green....if you get that situated, also get into the hiperarc and do a "list chassis" . Does everything look normal? You should have the HDM listed under it's slot with 24 ports. If nothing is listed there you'll get dead air or busies (can't remember which). You might have nmc chassis awareness enabled though which should take care of this for you. "show nmc settings" If it's disabled though...you'll need to configure the chassis slots manually.

OK. I'll try this. When it first went out, we got dead air answer. When I plugged the T1 into the older equipment and only four modems answered, it reasoned that the problem was on the T1. Especially since cycling power to our HDSL box fixed everthing on our old equipment. However, when we went back to the HiperDSP, it now totally missed the card - cycles past it like it wasn't there. I also tried swaping the backs of my two HiperDSP cards today. I figured that if lightning got though the HDSL modem and got to the HiperDSP card, it could not have blown the back of the second card (not connected to the T1 at all), so swaping the back in slot 3 with the one in slot 1 should have (but didn't ) fix things up. Anyway, I'll go through the settings with a finner toothed comb and see what I can find. It all looks OK.

If you just want to check if the circuitry is OK on the DSP you should do a loopback test. You can also make a loopback adapter by crossing the pairs. Do a google search for "t1 loopback" and you'll see the pinout. -- Lewis Bergman Texas Communications 4309 Maple St. Abilene, TX 79602-8044 915-695-6962 ext 115
OK, that's a good idea. I think I have a loopback adaptor left over from my old Equinox equipment I can use. It would help a lot to rule out (or in) that the hardware is toast or not.

Hi Lewis. I tried this with a LoopBack adapter that came with our Equinox Digital Modem Pools we used to have. When I initiate the Loopback test by setting the mode from NoLoop to Payload or Line, the LoopBack LED goes Yellow (test in progress) but it never comes back from yellow. Can you explain how the sequence should look? Perhaps the lookback adaptor I have is not the same - I haven't built my own yet, but will tomorrow. Actually, I think the T1 port is OK - at least the CAR light comes on green and the PairGain HDLS T1 modem's lights activate correspondingly, just that we get a dead-air answer. We've been though the trunk settings over and over, but I just don't see anything wrong. We get the same results on both cards, so we're back to trying a loopback to make sure the CAR lights aren't lying. So, if you could tell me what a successful loopback test should work like, I would be grateful. :-) Todd Chamberlain ----- Original Message ----- From: "Lewis Bergman" <lbergman@abi.tconline.net> To: <usr-tc@mailman.xmission.com> Sent: Tuesday, September 03, 2002 2:49 PM Subject: Re: [USR-TC] HELP: Lightning HiPerDSP

It just stays Yellow forever? It would be nice if it blinked a couple times and then went off or something for a successful test. Mine goes Yellow no matter what I set it to pretty much, and it stays that way forever. ----- Original Message ----- From: "Lewis Bergman" <lbergman@abi.tconline.net> To: <usr-tc@mailman.xmission.com> Sent: Thursday, September 05, 2002 7:24 AM Subject: Re: [USR-TC] HELP: Lightning HiPerDSP

My Settings in a old and forgotten world of CT1 I have been kind of following this thread, I run T1's and I received zero help from my TELCO, it turns out they had no clue and I was on my own. A Lucent PM-4 Manual really helped me... Here are my settings from my old T1, I am sorry I am not running Hiper stuff ----------------------------------------------------------------------------- 1 T1 Span Line 1 Framing Mode SF 2 T1 Span Line 1 Line Coding AMI 3 T1 Span Line 1 Remotely Initiated Loopback Respond 4 T1 Span Line 1 Jitter Attenuation Transmitter 5 T1 Span Line 1 Transmit Line Build Out 0.0 dB 6 T1 Span Line 1 Automatic Busy-out Disabled 7 T1 Span Line 1 Fractional T1 Byte Pattern FE Hex 8 T1 Span Line 1 Short Haul NIC Line Length Not Applicable 1 Set to Feature Group B Defaults 2 Set to Feature Group D Defaults 3 Set to Loop-start Defaults 4 Set to Ground-start Defaults Current Setting 5 Dial-in/Dial-out Trunk Type E & M type II 6 Dial-in/Dial-out Trunk Start Wink 7 Dial-in Expected Address No Address 8 Dial-in Address Acknowledge Wink Enable 9 Dial-out Address Delay 70 10 Dial-in No-Add. timeout no answer (0 fast-ans) 30 ---------------------------------------------------------------- Now in coming up with this stuff, I tried everything, in north america we do not use ground start anymore, if you are not able to set this kind of stuff maybe your software does not support CT1? Do not use Ground Start; no one in north america does. Hope this helps PS. if anyone can improve on this let me know, Thanks! -Cyrus. cyrus@mtio.net
