I use a DSL-G604T router on my Vodafone connection.
On the test page for the router there are two section regarding ATM which always show up as fail :-

The WAN settings are :-

I assume that the failure is unimportant since my connection works but I am sure that prior to the recent change in the Vodafone network that these items did not show up as failing.

Has anyone noticed same thing?

I think ATM os Automatic Traffic Management.
It appears that this runs on OAM (operations, administration, and maintenance) as an interface.

I am guessing, but this might work in conjunction with an advanced routing management software interface which manages multiple routers & their extended networks.

ATM - Asynchronous Transfer Mode

ATM is an encapsulation mechanism for data packets. In your case your Router takes the IP Packets inside the Ethernet frames from your LAN and puts them into ATM cells to be sent over DSL to the local Telephone exchange.

Clear as Mud?

Short for Asynchronous Transfer Mode, a network technology based on transferring data in cells or packets of a fixed size. The cell used with ATM is relatively small compared to units used with older technologies. The small, constant cell size allows ATM equipment to transmit video, audio, and computer data over the same network, and assure that no single type of data hogs the line.

Some people think that ATM holds the answer to the Internet bandwidth problem, but others are skeptical. ATM creates a fixed channel, or route, between two points whenever data transfer begins. This differs from TCP/IP, in which messages are divided into packets and each packet can take a different route from source to destination. This difference makes it easier to track and bill data usage across an ATM network, but it makes it less adaptable to sudden surges in network traffic.

When purchasing ATM service, you generally have a choice of four different types of service:
1 constant bit rate (CBR): specifies a fixed bit rate so that data is sent in a steady stream. This is analogous to a leased line.
2 variable bit rate (VBR): provides a specified throughput capacity but data is not sent evenly. This is a popular choice for voice and videoconferencing data.
3 available bit rate (ABR): provides a guaranteed minimum capacity but allows data to be bursted at higher capacities when the network is free.
4 unspecified bit rate (UBR): does not guarantee any throughput levels. This is used for applications, such as file transfer, that can tolerate delays.

you never go ATM!


For billions of years since the outset of time, every single one of your ancestors survived, every single person on your Mum and Dads side, successfully looked after and passed onto you life.  What are the chances of that like?

Thanks for all the info guys and a special thanks to the banker.
(You do know that the collective noun for bankers is a "wunch"?)

From what you have all said I guess I can safely forget all about ATM and ignore the failed pings when I run the test on my router.
