Or 10kbits/s (little b) 8 bits in a byte...a "64k" ISDN is 64kbits..not 64kBytes. flat out you should see about 8kBytes per second across that line. (for reference you'd get 64kBytes on a 512k link.) If you really are only getting 10kbits across an unloaded line, I'd start looking for serious line or modem issues at one or both ends. ....david --- david raistrick (deep in the south georgia woods) [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=8463&t=8445 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
