Recently we've deployed a fresh installation. But from the start we had some issues with a fax connected via a Cisco ATA 186 to a Linksys SFE2000P-EU switch. Which then is connected to a Cisco 3560. All ports on the Cisco 3560 are looking fine, but if I look at the port to which the ATA is connected I see a lot of Single Collision Frames! Is this because the ATA is running on 10Mbps/Half Duplex? Because I don't get to see these errors when I connect the ATA directly to the Cisco 3560. And is it possible to solve this issue, because the customer is complaining about missing faxes.
