Actually, the ISDN approvals that I am familiar with (USA, Canada & Japan) don't _require_ a product to do both 56kbps & 64kbps on the B-channels -- that is left up to the manufacturer. However, since it is still quite likely that either speed could be necessary in a "real life" connection, I think it would be wise to support both. ________________________________________________________________ John Combs, Senior Project Engineer, ITS/TestMark Laboratories Email: [email protected] URL: http://www.testmark.com
