Is this formally a dedicated line (fractional E1/T1), or is it frame relay? If it's a true leased line, you should have the bandwidth. >But now when I feel the access is very slow too but the link is not >congested with only 25% utilization.

Most of the newer undersea cable installations go in as 4-site SONET rings. Hypothetically, you might be on a ring Sydney-Singapore-Los Angeles-San Francisco. If the Sydney-LA link is the one you normally use, you may be going Singapore-San Francisco, with longer delay. Better longer delay than infinite delay! >I suspect is that because the >undersea cable utilization is very congested, so the provider only allocated >small bandwidth to us. Is that possible? How to determine?? Will provider >cheat us on leased line bandwidth or the RTD affect a low on performance? Start by asking them, including a request to see the data circuit layout.
