In 12/99 we quoted and resold PSINet InterMAN T1 service ("full" 1.17 speed) to a customer, but during installation BellSouth absolutely could not provision as prescribed. After several attempts and delays, PSINet offered us 1.54 T1 Frame Conn @ 50% CIR instead. Its unclear now if our ex-sales rep ever communicated change of service to customer, as all parties have departed. New person at customer site now complains of slow speed after 1 year+ of service. Says he's owned dedicated T1 and FR before and this is no T1 speed. Talking about year's worth of "fraud" on our part. Yikes!! PSINet's tests show no hint of any speed problems. Our attempts to test onsite via internet speed tests (timed file download) produce results in the 30% to 50% of expected "T1 speed". How best to monitor slowness, perhaps just to certain sites? Or at certain times? Additional problem in that our cost for FR was actually about $100 higher than cost for InterMAN. I would have thought FR should be lower, but PSINet called it an upgrade (meaning: more $$$ to PSINet). Just looking for comments, suggestions or sympathy.
