Hi; Thanks for your suggestion, Craig - unfortunately, this fix didn't work out for us. We found that both channels could be brought up, but, as before, after a certain amount of time, the link went dead, even though the lines stayed up. Even before it reached this point, the connection was very slow and unreliable - when we pinged their IP address from the Ascend they were connected to, we typically only got every other packet back, at best. It seems that something is fundamentally going wrong when we switch to dual channel. A PPP connection works fine, but whenever we set ppp on the Cisco to multilink, causing them to negotiate an MPP connection on the Ascend, that's when the trouble begins, with very poor network performance, and eventual deterioration to the point of no throughput. Once again, thanks for the suggestion - can you (or anyone else on the list) think of any other possible cause for this problem, or something else we can try to fix it ?
