ATM has recently gotten to the point where it can outperform Fast Ethernet in a common environment with office applications, some homegrown apps, e-mail and graphics packages. The ATM vendors we've worked with have shown a desire to make their products work together. But the standards are relatively new, and sometimes we run into interpretation issues. It is logistically hard to keep the fleet supported, keep the IT infrastructure up, repair things and get them back. Afloat or ashore, there is no standard warranty.
Different warranties do different things different ways for different lengths of time.
You have finger-pointing, and you have to make sure you have adequate coverage for all parts. All the contracts offer a standard type of warranty. Often what the fleet needs is a spare in the air. Let's assume that a needed part is in inventory on a ship. They send the part to their port of supply.
