In this Podprofile — a complementary Audiocast for a joint
Telecommunications/Vertical Systems Group Webinar, "Ethernet Solutions for Cell
Backhaul Applications" — Mike Rouleau, Senior VP of Business Development, Time
Warner Telecom talks to Executive Editor Sean Buckley about how it is delivering

carriers adopting or considering using IP/Ethernet for wireless backhaul. What’s
driving the migration from TDM to IP/Ethernet for wireless backhaul and how does
Time Warner Telecom approach this opportunity?
As part of your wireless backhaul you are using ADVA equipment. How important
are their platforms to offering wireless backhaul to cellular operators?
What are the measurable benefits to the deployment of Ethernet solutions for
To help ease the migration pain for a wireless operator using Ethernet for
backhaul, there’s been talk about IP/Ethernet architecture for backhaul where
you maintain TDM for voice and then Ethernet for data. Are you seeing a similar
One issue that’s gaining momentum is dealing with clock synchronization when
using Ethernet for wireless bakchaul. How is TWT addressing that issue?
Given the dominance of copper facilities in the ground, during last year’s CTIA
show, one of the surprising trends to come out of discussions was centered
