Joel: I just changed on setting, the "Primary Switch Type" and the 'Busy Signal' is gone. Thanks again. Kirti Joel: Thank you for your suggestions. I plan to setup/test 3Com by following them. One question: How to reset Hiper DSL to factory defaults? Thanks again.

Subject: RE: [USR-TC] RE: Busy signal!!! Importance: High Kirti - Here's the thing with getting PRI's going, and although I don't consider myself an "expert", to my knowledge and from my experience, this is all there is to it: 1. Reset your Hiper DSP(s) to factory defaults, and reset it. 2. Go into the Trunk Settings on the DSP and set the "Primary Switch Type" to whatever kind of switch the telco is using. (This is usually the one and only piece of info you need to know, as far as trunk settings). Save your settings and do a hardware reset on the card. (FYI - in my experience, all of those trunk settings on the DSP are really only needed for CT1's. PRI's are more standardized and always work with the default settings. The only thing you have to change is the switch type, which I believe basically determines the messaging protocol on the D-channel or something like that.) ALSO... note that sometimes the telco will tell you the wrong switch type. For example, they may say it's a 5ESS, which it may physically be a 5ESS, but if they configured your PRI as what they call "standard", it's actually running as an NI2. On a 5ESS switch, they have to configure your PRI as what they call a "custom" in order for 5ESS to be the correct setting. I think we had a similar confusion with a DMS100 one time also, if I remember correctly. I gather that from things I've heard that NI2 is like an old standard, and a lot of different switches support NI2 and a lot telcos still provision PRI's as NI2 PRI's. ONE More thing - I've found that even with the wrong switch type specified, a lot of times the line will still ring. It can still cause busy signals, but more often strange things like intermittent drop out on your D-channel, calls not hanging up, or other funny things happening. But when you've got a constant busy signal on the line, it usually ends up being an ARC issue. 3. Once the DSP card reboots, it should take calls. If it does you're done. If it still doesn't, then the problem is with your Hiper ARC, go on to step 4. 4. If you have only more than one Hiper ARC, take one of them out of the machine. (technically, this is just to avoid conflicts related to chassis awareness, card ownership, whatever. If you need both ARC's, you can configure and put the second one back in after you get the chassis taking calls). 5. Connect a terminal to the serial port on the ARC that's in the machine. Enter the command "delete config" and "Y" when prompted. This will reboot the ARC with factory defaults. 6. When the ARC starts up and prompts you, go through the "Quick Setup" and do the most-simple, most basic config you can. Give it an IP address, default Gateway, a radius server, admin password, dns servers, and an IP address pool. When asked if you want to use chassis awareness, answer YES for now. (This should work fine with just one ARC). When it's all done, do a "save all" and then a "reboot". 7. When the Hiper ARC is rebooted, and comes back to a "Hiper>>" prompt, try to dial it. If it rings, you're working, now just finish configuring the ARC, or delete the config again and set it up the way you want. If it still gives a busy signal, go on to step 8. 8. Disable NMC chassis awareness. To do this, enter the command "disable nmc chassis", press enter, then use the "reboot" command to reboot the Hiper ARC. 9. After the ARC boots, enter the following commands: set chassis slot 1-14 card hdm_24 ports 23 own y save all reboot 10. This time, when the ARC reboots, it should ring. If not, there's something wrong with the PRI from the Telco, wrong with your DSP card(s), or wrong with your Hiper ARC. If you have a second ARC, you might try pulling out the one you have in now and putting in the one you took out in step 4, and then follow steps 5-9 again and see if it works this time. In addition - should say, I prefer to have the latest TCS 4.5 code on the cards before doing this. Now - this may all seem simplified, and depending on how much of the config you do to the ARC, it may or may not work. But these steps DO get the PRI to ring in EVERY time, as long as you don't have broken hardware and you know the correct switch type at the telco. Hope that helps. - Joel -----Original Message----- From: Kirti S.

In my last discussion with Sprint, they informed me that there is no setting they normally provide for an ISDN-PRI's. I have been changing settings to see if something works. I have some new findings: (1) I can test the 3Com with a UID/PW by using the "_auth UID PW" command (2) When I connect a ISDN-PRI line into HiPer DSP, the D-Channel gets locked. Then when I dial-into the line, it is /busy/. Is this information sufficient for somebody to give some hints? Thanks in advance. Kirti -----Original Message----- From: Kirti S.

Hello list: I am dead end. I posted this message over two months ago. I still have not been able to get settings from the telco (Sprint). Is there anybody in Tennessee who has a ISDN-PRI line (1D+23B) from Sprint? If you do, I appreciate if I can get the settings for the trunk from you!! If somebody has any other suggestion please let me know. Please respond. Thanks in advance.

Subject: Re: [USR-TC] RE: Busy signal!!! I'd try to verify the dsp span settings with the telco. In particular things such as dnis/ani and the number of digits being sent by the switch. If you aren't on the same page with the telco as far as though settings go you can get busy signals. Todd ----- Original Message ----- From: "Kirti S.

Todd:
Thank you for your reply.
chassis awareness is ENABLED list chassis does show port 23
Any other suggestion?
Kirti

There could be a variety of things that cause this. How do you have your chassis awareness setup?
When you're in the arc and do a list chassis command does everything look correct as far as number of ports=23, etc?

Hello List:
I finally got 3Com box (1-HiPer NMC, 2-Hiper ARC & 10-Hiper DSP) setup. Today, I connected a T1-PRI ISDN line to test. But as soon as I connect, the line gives busy signal.
What setting causes this. /Please Help/. Thank you in advance.
Kirti
