When I worked for Global Crossing back in the early 2000's, AT&T Local had a 5E in the same building as us. I didn't have the opportunity to walk around the rows of frames, but it seemed like a good switch from what their technicians said. We had a DSC DEX-600E, Nortel DMS-500 and later a Sonus packet switch.

Verizon has a 5E in my town, but it is going to be coming out of service once the Copper OSP Retirement project is completed. It is my understanding that Nokia is now supporting the 5E
