FW: [USR-TC] RE: Dial-In Problem!!!!

Hello: For the last few days I have posted the following question: ============ Please help. This problem is going on for the last 7 weeks without fixing. TC1000 1-HiPer NMC 2-HiPerARC 10-Hiper DSP We are a small ISP (400 customers). We have 2-ISDN-PRI lines for our customers to dial in. Our entire system looks like this: / / T1 to External Internet / CISCO 26XX Router | HUB 10/100 | ---------------------------------------------------------------| | | | | | NMC ARC1 ARC2 Web Authentication ----------- 3Com ------------ Server/Email | | | | | | | | | Customer Dial-In Our customers can dial-in, are authenticated and can access the internal web site (www.tibonline.net) and retrieve their email. But when they try to connect to any web site (outside our network) on the external net (such as www.yahoo.com) they time out with a message saying that "this page can't be displayed". We have changed the HUBs, RJ45 cables. We have the CISCO Router tested fine. Finally, I replaced the 3COM box with a backup box and the problem continues. Interestingly, we can access any Internet web site (www.msn.com, www.yahoo.com, etc.) from our internal network (over LAN) without problem. ============ Since posting the above message, we have received a number of responses. Charles suggested to see how the CISCO 2600 was assigning the IP addresses (or something similar!!). For the last two days, AT&T technicians has been working with me to look into the router. They have setup static address and have done number of settings without success. I have switched 3COM to a backup 3COM box. Following are new the IP address: NMC (Port 17) 12.21.237.240 ARC1(Port 15) 12.21.237.241 IP Pool: 12.21.237.48/31 ARC2(Port 16) 12.21.237.242 IP Pool: 12.21.237.96/31 The problem is that out Dial-In customers can dial-in, access the internal network (email, authentication, DNS, Web Servers) but can not access the external Network (www.msn.com) etc. I have setup a dial-up PC (Win XP Pro) to test. The first time I connected, the IP address assigned was 12.21.237.98. I could not access the external network. I tried to do a external trace from www.traceroute.org. Following are the results of the trace. -------- Call this TRACE-1 Testing the network route from EASYNEWS.COM to 12.21.237.98...

In TRACE-2 (outside network is connected & the dial-in connection works), the trace gets to my dial-in terminal (12.21.237.99). I have noticed couple of things in the above traces. In both traces, ARC1[Kirti S. Bajwa] (12.21.237.241) is first traced even though the IP address of my terminal (12.21.237.98 or 12.21.237.99) is on ARC2 (12.21.237.242)!! Can someone explain why trace is always first going to ARC1 IP? Can someone explain what is going on? Why sometime the dial-in wotks (access the external network) and other times it does not? AT&T is going to call back around 3:00PM (EST) to help. Is 3COM needs some settings changed? Thanks in advance. Kirti

Check your Timeslots for Local/Remote Out of Service messages. It may also be that two timeslots are mapped [Timeslot Mapping and Blocking] to one Modem or something of that nature. -----Original Message----- From: usr-tc-bounces+adam=semo.net(a)mailman.xmission.com [mailto:usr-tc-bounces+adam=semo.net@mailman.xmission.com] On Behalf Of Shahrooz Sharghi Sent: Tuesday, July 26, 2005 12:26 PM To: Discussion relating to the 3Com/US Robotics Total Control modemsystems.

Saving serttings problem!!
by Kirti S. Bajwa 25 Jul '05

Hello: System: TC1000 1-HiPer NMC 2-HiPerARC 10-Hiper DSP Problem: I am trying to setup this 3COM chassis. I open the Total Control Manager & select all DSP cards. Then I make the changes. Then: Software > Save Both T1/E1 and Modem to NVRAM > Execute Software > Software Reset > Execute Configure > Action/Commands This portion of the DSP settings and saving is success. Then I try to save the Chassis, as follows: Select NMC Card. Configure > Action/Commands Software > Save Chassis to NVRAM > Execute NOW THE PROBLEM. Sometimes there is "Success" and other times the result code "InProgress" stays on for ever. What is the problem? Is there any other way to save the DSP settings? I am working on this problem for 2-weeks and any HELP is highly appreciated>. Thanks, Thanks & many many thanks for a quick response. Kirti

FS: Chassis, analog parts, misc.
by Charles Sprickman 21 Jul '05

21 Jul '05

Hello all, I posted some of this stuff a few weeks ago, but decided to go the EBay route since I'm not sure what it's worth. We have two auctions running, one for two chassis, one for a bunch of misc. parts, including the hard-to-find analog NICs and quad-cables. We recently went with outsourced dialup (yeah, it's hard to give up control, er... Total Control, yuck yuck yuck) so we don't need this stuff. We're also moving to new offices, so it's time to ditch things we don't use. As noted in the parts auction, I'll probably find more oddball stuff as we pack, so the winner there can choose to take whatever else I find if interested. Here's the two auctions: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5791216228&ssPageNa… http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5791221070&ssPageNa… Apologies if this offends... Feel free to contact me directly at this email address with any questions. Obviously if you're local you are more than welcome to visit us to pick this stuff up.
