Ping times

Reading your question - I ping tulsaconnect.com -l 500 -t and im getting 0% loss and 25ms returns.

Im in Oklahoma City and tulsaconnect.com is in Tulsa Oklahoma - about 150 miles away.

Id make sure all services on both ends were stopped for a interference free call. See what that does for ya.

yeah I think you've a router/switch in there thats unreliable. 19% packet loss is pretty bad for a T1 dedicated especially for how much it costs ya.

this doesn't pertain to dedicated links, but you can see reliability reports on different ISPs at Broadband reports. Here's a link to their tools page with lists a 24/7 ISP report and whos how good or how bad Link shows California http://www.broadbandreports.com/monitored/CA

Compare this which is public ISPs to yours which is dedicated. You'll see that public is doing better than your private dedicated line and the public ones cost much less.

Have the telco test that circuit. You should not be getting any data loss and your ping times should be a whole lot better.

19% loss sucks. With modern equipment 5k packets should regularly come back with zero loss.
First check all your cables are undamaged and are seated properly. Next port of call should be your carrier.

You are getting results that are common to a frame relay with a low cir rate.

Contact your provider and have them research the link. They should be able to pull up a history on the line and tell you where the problem is.

Good Luck
