It wasn't my intention to imply that CT1s will perform worse when there are line coding mismatches somewhere in the chain.... However, I didn't explain why I said that CT1 is the first ingredient in a recipe for 56k trouble: and, the answer is: RBS. CT1 means you've got an RBS link between your equipment and the telco. If there is any other RBS link in the call path to the customer (ie, SLC, remote office trunks, etc.) decent 56k connections may be impossible unless the RBS links align - a 1-in-6 chance. 56k client modems are supposed to be handle multiple RBS links, but they often do not.

Aloha,
