I am working on a solution that will require my CBX-500 to do transparent mode and not translation mode. I've grepped the docs I have and looked on the web and can't find reference to which mode the CBX uses. This cross connect would be between the FR 3/1 card to the ATM DS3 card. Does anyone know which mode the CBX uses ? -- James H. Edwards Routing and Security Administrator At the Santa Fe Office: Internet at Cyber Mesa jamesh@cybermesa.com noc@cybermesa.com (505) 795-7101
