Adtran Atlas 550 alternatives

Greetings; I have four Adtran 550's (one at each site) with a T1 Connection providing data only communications to each location. I am interested in replacinf these devices with newer less exspensive alternatives. Question 1: Would a Cisco 1720 provide a simple soltution for terminating a T1 to Ethernet 100 Mps. Question 2: If this would not be an option, what Cisco box would provide the needed termination/routing? Question 3: If a Cisco device could do this would it be necessary to replace them at both locations or could it communicate with the Adtran device? Thank you in advance for your assistance!!!!

It depends on the topology of how your sites are interconnected to each other. Please describe in greater detail.

Don;t know ip adress adtran612

Maybe the user manual you can find at will shed a light on your problem ?

You may try, with a computer successfully hooked up to the router, to type ipconfig /all in the Command prompt. If your router's DHCP is on, you should get it's IP address in the "Default Gateway"

Can't connect Dell TrueMobile 1184 with Adtran NetVanta 3200

It sounds like you need to "crossover" the connection.

Using a crossover patch cable to connect the two devices is the first thing that comes to mind. (

However, some routers/switches have physical buttons on ports to cross them over or you can use their web-based management to change port settings.

I hope this helps.

Keep getting a 401 unauthorized code when trying to log in to sur

Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) was correct, but access to the URL resource requires user authentication which 1) has not yet been provided or 2) which has been provided but failed authorization tests. This is commonly known as "HTTP Basic Authentication". The actual authentication request expected from the client is defined in the HTTP protocol as the WWW-Authenticate header field.
Generally this error message means you need to log on (enter a valid user ID and password) somewhere first. If you have just entered these and then immediately see a 401 error, it means that one or both of your user ID and password were invalid for whatever reason (entered incorrectly, user ID suspended etc.).
401 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle:
Obtain an IP address from the IP name of your site (your site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
Open an IP socket connection to that IP address.
Write an HTTP data stream through that socket.
Receive an HTTP data stream back from your Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code it recognises as '401'.
Fixing 401 errors - general
Each Web Server manages user authentication in its own way. A security officer (e.g. a Web Master) at the site typically decides which users are allowed to access the URL. This person then uses Web server software to set up those users and their passwords. So if you need to access the URL (or you forgot your user ID or password), only the security officer at that site can help you. Refer any security issues direct to them.
If you think that the URL Web page *should* be accessible to all and sundry on the Internet, then a 401 message indicates a deeper problem. The first thing you can do is check your URL via a Web browser. This browser should be running on a computer to which you have never previously identified yourself in any way, and you should avoid authentication (passwords etc.) that you have used previously. Ideally all this should be done over a completely different Internet connection to any you have used before (e.g. a different ISP dial-up connection). In short, you are trying to get the same behaviour a total stranger would get if they surfed the Internet to your Web page.
If this type of browser check indicates no authority problems, then it is possible that your Web server (or surrounding systems) have been configured to disallow certain patterns of HTTP traffic. In other words, HTTP communication from a well-known Web browser is allowed, but automated communication from other systems is rejected with an 401 error code. This is unusual, but may indicate a very defensive security policy around your Web server.
Fixing 401 errors - CheckUpDown
When you set up your CheckUpDown account, you may optionally provide two items 2. Web Site User ID and 3. Web Site Password. You should provide these only if your site uses HTTP Basic Authentication. If you provide them, the CheckUpDown robot always uses them. This will result in a 401 error if in fact your site does not use this authentication. Conversely, if you do not provide them and your site does use this authentication, you also get a 401 error.
If however your URL is open to all comers, then an 401 message should not appear. Because it indicates a fundamental authority problem, we can only resolve this by negotiation with the personnel responsible for security on and around your Web site. These discussions unfortunately may take some time, but can often be amicably resolved.
Alternatively or the other way around is :

open the XP hosts file, and do a manual insert there.
The hosts file is located at: C:\WINDOWS\system32\drivers\etc
The entry is:
You might need to flush your DNS records at this point, or simply restart your computer.
And then use the following URL to access the admin page:
***Here is another solution to the problem, which is a fairly straight-forward way to disable the annoying wizard.
Type in your browser:
Select: Disable Configuration Assistant, and click on Apply.
You can re-enable it by navigating to (where is your router’s IP address)

T! lines

A T1 line is a dedicated connection to an Internet backbone router. Typically a T1 line is for major businesses and school campuses. A T1 line is capable of handling 637 simultaneous VOIP connections with full-duplex connection.

How many computers do you intend to have connected to this network? Even a fractal T1 is very expensive. A full T1 connection can cost nearly 25K per month usage. A T1 line will need to be installed by your ISP provider and this too will cost a significant amount of money and it depends on how close your network connection will be in relation to the main network trunk-line.

If you trying to connect a T1 line to a Belkin 54g wireless router, you are way out of your league. I have worked for several networking firms in the Atlanta, GA area and we never had more than a fractal T1. Most small to midsized networks (up to 100) users can be accommodated with using a DSL or Cable Internet connection with a dedicated firewall and router/switch to handle the network traffic. Unless you are willing to pay for a T1 fiber optic line to be run from the main trunk line to your place of business or home, you will be fine with a high speed cable internet connection from an ISP provider like Comcast of Qwest here in the US. Fiber still has an installation cost of about $10,000USD per 1000 feet.

Hope this helps to clarify your problem.

Cctv remote view/ adtran total access 900e

It's not likely that VZ gave you dynamic IP's, but it's possible. You should have been given more than one. If not, it's better to get more and a set of configuration instructions. In the last one I set up, we put a 5-port switch on the ethernet port coming off the Adtran, then fed 2 routers and a security system from the switch. Our gateway was one number lower than the bank of IP's we had, and we just gave each piece of equipment a static ip address and gateway to the gateway :-)

How fast can the data go?

The speed of the cable modem is only one part of the equation. There are a combination of factors starting with how fast your PC can handle IP traffic, then how fast your PC to cable modem interface is, then how fast the cable modem system runs and how much congestion there is on the cable network, then how big a pipe there is at the head end to the rest of the Internet. Different models of PCs and Macs are able to handle IP traffic at varying speeds. Very few can handle it at 30 Mbps. Ethernet (10baseT) is the most popular cable modem interface standard for the PC. This automatically limits the speed of the connection to under 10 Mbps even if the cable modem can receive at 30 Mbps. Most Local Area Networks use 10baseT Ethernet, and although they are 10 Mbps networks, it takes a LOT longer than one second to transmit 10 megabits (or 1.25 megabytes) of data from one terminal to another. Cable modems on the same node share bandwidth, which means that congestion is created when too many people are on simultaneously. One user downloading large graphic or video files can use a significant portion of shared bandwidth, slowing down access for other users in the same neighborhood. Most independent Internet Service Providers today connect to the Internet using a single 1.5 Mbps "T1" telephone line. All of their subscribers share that 1.5 Mbps pipeline. Cable head-ends connecting to the Internet backbone using a T1 limit their subscribers to an absolute maximum of 1.5 Mbps. To create the appearance of faster network access, service companies plan to store or "cache" frequently requested web sites and Usenet newsgroups on a server at their head-end. Storing data locally will remove some of the bottleneck at the backbone connection. How fast can they go? In a perfect world (or lab) they can receive data at speeds up to 30 Mbps. In the real world, with cost conscious cable companies running the systems, the speed will probably fall to about 1.5 Mbps.
