Thanks to everyone who has responded so quickly to my question.

To my way of thinking, it would be better to have the legacy tie-line 
reconfigured to use esf if possible.

Is D4 (superframe) well supported in Asterisk, are there less features? 
  If it is virtually the same, then I guess I will just setup Asterisk 
to use it rather than messing with the legacy system.

Thanks,
Steve
