They are meant for casual desktop users that would never put any amount of load on them. About 6 years ago we needed some PCMCIA modem cards and bought 100 of them from a vendor for $25/ea. They started failing in the field. When calling they just could not sync up. Only a reboot could fix the problem. What we learned was that a combination of heat and other factors caused them to drift so much the timing was off. We replaced those in the field with Zoom 3075 at about $65/ea. These modems were not meant for our solution. They were meant for casual laptop users that needed to dial an ISP every so often. I was expecting them to work in a box that would stay up 24x7. They couldn't handle it. I wrote a perl program that used a TLS-4 simulator and would dial the modem constantly. The failures were too much. On the Zooms we would average 10 failures per 1000 calls. -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
