Just curious if any one has seen this or could offer any tips. We have a weird issue with a remote site over a T-1. We have a full point-to-point T-1 with a remote site to the main facility. The T-1 is in no way over utilized, users experience issues with their TCP based application when there is only 4% or so of traffic on the T-1. The site really doesn't ever come close to over utilizing the T-1. Now the weird part is this seems to only happen around the HOT months, but can happen at other times. The equipment and both sides has been checked and there seem to be no environmental issues. There are no errors on either serial of routers at either end. We have had both carriers test their ends of the T-1 and they come back clean and no issues or errors. Any suggestions would be greatly appreciated.
