It's more than likely interleaving which is causing the latency, it's used in order to reduce line errors (and to increase reach) but a side effect is that it increases latency. The verizon connection is more than likely not using interleaving while the Qwest connection is. John -- John Lyons Phone: +353-1-660-9040 Network Engineer Fax: +353-1-660-3666 HEAnet Ltd.
