And with CS-03 in Canada, which, thanks to "harmonization," is the same subset of tests as in the U.S., at least for T1 interfaces. >What about ANSI T1.403 and AT&T 54016 compliance?

Those are all optional (but some of the RBOCs and GTE may require you to show compliance before they'll buy your stuff for their own use, depending on what it is that you make). Very few end-user T1 products implement things like PRM generation, alarm reporting, etc., as it is somewhat futile. The telcos cannot be sure that end-user products support such things, so they typically terminate a T1 line at a customer premise in their *own module* which handles those functions, then that module connects to the end-user device. And that module "blocks" the commands from ever reaching the end-user device, which is why I say it is futile to implement them. <g> ________________________________________________________________ John Combs, Senior Project Engineer, ITS/TestMark Laboratories Email: [email protected] URL: http://www.testmark.com
