[c-nsp] Feeding low bandwitdth Ethernet WAN links with Cisco 6500

Hello QoS experts,

I am thinking about the best practice to feed some low bandwitdh 4 Mb/s 
Ethernet over SDH links from a Cisco 6500/Sup720 with SXI IOS.

The carrier equipment has 100Base-TX ports, does no noticable 
queuing/shaping and aggressively drops everything over 4096 kb/s.

The links carry internet traffic and DSCP marked RTP traffic for VoIP.

So we need priority queueing for the voip within the total of 4 Mb/s 
available and make the 6500 aware of the limited bandwith on the 100 M 
ports.

I am sure someone has done (or tried) this already. Does it work?
Any ideas, experience and best practices greatly appreciated.

Thank's a lot!

Michael
