I think that Tellabs used TL1 for high bandwidth DCS such as the 5500. While the 532L can work with those types of circuits, it is primarily a low bandwidth DCS. I have not seen the 5320L during my years as a CO tech for an IXC/CLEC.

I wish that Tellabs didn't do away with the command builder function in the 5500. It made my job simpler.
