Our local podunk (sp) phone company can now deliver phone lines to me on t1s, with Super Frame and AMI encoding. vs all our other pops which are PRI based. What are my quality of service expectations for sf/ami? This an upgrade in their CO from regular pots lines which we have been using for quite some time. My bottom line is to now be able to deliver x2/v90 to my customers vs the v.34 connections I have been giving them. Will I or my customers notice the difference in quality vs a pri based system? thanks eric - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
