We used that topology, with an Adtran MX 2800 19" rack version. We would take our channelize DS-3 from the Telco and the Cisco PA-MC2T3 cards and in turn wire those to a DSX-1 panel. We then did 1 to 1 DS1 X-connects on the panel. That was starting to get too much of a pain as services grew, so we went with a DACS and that took care of having to do all that DSX-1 wiring. Ugh.

The ASRs seem to be the consensus in a lot of places. Wondering if anyone has tried anything like aggregating T1 customers onto a mux box, then connecting that back to a 6500.

I work in that kind of topology all day long/ both in 6500 & ASR's. All is well/

Hello,

I'm looking to put some feelers out there and see what people are doing to aggregate WAN customers (T1,T3, etc...) these days. What platforms/devices are you using? What seems to be working/not working? Any insights would be great!

Thanks,

Chris
