Long answers are great, if you don't mind lots of Q's. We come seeking knowledge. So if I understand correctly, the 5500 not only switches DS0 traffic between ports (sending calls to the appropriate C5 switch, be it the LEC's, an IXC or CLEC), but it also aggregates and routes the FR/IP/ATM traffic coming in on the DS3/DS1 ports to dedicated FR/IP/ATM ports for transport/switching on the respective packet NW? Do the DS1/DS3 inputs now carry mixed traffic? Can 5500 ports be provisioned to accept a mix of DS3 and DS1 ports within a frame, and then the sw fabric handles the switching at the DS0 level regardless? Is CLEC/IXC interconnection w/ the LEC's a significant portion of the DCS port demand as traffic between carriers grows w/ customer fragmentation (a port acts as a dedicated line between the LEC/IXC/CLEC)? AN2100: as I understand it, it will sit on top of the C5 sw on the edge of the backbone and act as an TDM/ATM gateway, yet you describe it as CPE, implying it combines IP/ATM/FR traffic w/ PBX outputs in the enterprise. Clarification? Also, will ATM sw's evolve to the pt where a small/med size business can plug all of their wires into an ATM CPE sw which connects to a core ATM sw? How soon? Finally (for this mssg), it seems to me that once ATM sw's can perform DCS functions (and the traffic volumes are sufficient) that they would still be relegated to service fewer, yet higher capacity feeds, because of the lower port density/footprint.
