There is a bit of overhead along with 24 * 64 for 1.544 Mbs. Even this is not set in stone, but is the guaranteed minimum rate. I've seen up to 1.724 on one of our T1s. E1s have 30 channels. Still the question was missed. There are no E1s in the US, unless someone cares to step in and say they do and by the wording of the message, it is a US company with a subsidiary that is *in* Germany. ------------------------------------------- Jeff Mountin - System/Network Administrator jeff@mixcom.net MIX Communications Serving the Internet since 1990
