FW: [USR-TC] RE: Dial-In Problem!!!!
by Kirti S. Bajwa 30 Jan '06

30 Jan '06

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

Hiper DSP T1 / E1 cards ?
by Teodor Georgiev 30 Sep '05

30 Sep '05

Hi, I got a good deal on some refurbished Hiper DSP cards. The issue is - the guy says they work on T1. Unfortunately E1 is my only choice. What gives me some hope is that on the back of the chassis one can see the sign "Hiper DSP T1/E1 NIC". Also, some voice gateways (like Quintum) can switch the port from T1 to E1 (and vice versa) only by changing a simple settings inside them. So, my main question is - can I upload an E1 firmware (R2 CAS) into the Hiper DSP card with the idea to switch it from T1 to E1 ?

Where to next?
by Wayne Barber 30 Sep '05

I've been using TC1000 for over nine years now at this ISP. I've been through some problems with Netserver cards and bad code - there was even a time I was considering going to Portmaster equipment before it disappeared. But over those years, USRobotics, 3Com and Commworks were upgrading the code and making the modems work better. Then they upgraded the hardware to the point where things work pretty smoothly now. But what's next? The current owners don't appear to have made any new code at all. Will there ever be any more improvements? I know I can get used TC equipment for next to nothing, but is there something better out there? If anyone on the list has moved away from the TC1000 to another solution, I'd like to hear what you are using, why you switched and how it's working out.

FreeRADIUS does this. Never used the call-back feature, but the DNIS/ANI shows up as called/calling station ID. -----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, September 27, 2005 10:35 AM To: berto(a)core.com; Discussion relating to the 3Com/US Robotics Total Controlmodemsystems.
