Dan,
Are you saying that Frame Relay access is less preferred than PTP access?
Maybe in Metro areas, but nowhere else, speaking solely in terms of cost.

Can you give me the part number for CHOC3? Does not exist at this time.

In which country are you speaking of? We have hundreds upon hundreds of DS1
ports landing on CT3 cards from the LEC.

Sure there is. He was asking about OC3. 3:1:0 muxes are plentiful. But
you are still terminating DS1s in your POP from the LEC. This is less
desirable as the number of DS1s rises. If CT3 service is available, and you
have more that 8T1s, then get CT3. If not, get M13 muxes and do the
cross-connect yourself.
