UGH! Note that ADSUs do NOT fully implement rate shaping and have interesting buffering constraints. This can cause interesting problems. The ADSU <> DS3 solution isn't a bad one if you are going to pull less than about 15Mbps through the line. If you're going to pull more, then save yourself a BOATLOAD of headaches (and heartaches) and go for the AIP card directly in the CISCO box. In *general*, if you're running a CISCO router, there is not all THAT much cost justification for doing the ADSU/HSSI thing (a few thousand bucks) when its all thrown together. -- -- Karl Denninger (karl@MCS.Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly to FULL DS-3 Service | NEW!

what box can i use to convert PacBell ATM (for PacBell NAP) into HSSI?

That is about right, if Kentrox has not further developed this box since I last worked on the PacBell NAP project. If you need full rate DS-3 ATM, gulp hard and go for the cisco AIP interface. You might want to send a note to ca-nap@pacbell.com and ask current NAP members if they have an old Kentrox ADSU lying around after a cisco AIP upgrade. You can start with that and upgrade later if you need to. --Kent
