TLS/EPL WAN Services

Does anyone know anything about Verizon's (or any other carrier's) EPL service?

Verizon has a MAN service called TLS (Transparent LAN Switching), which does NOT support QoS/CoS. I guess it has something to do with the manner in which the TLS service tags and trunks the traffic.

They do, however, have a MAN service that does support QoS. It's called EPL.

Has anyone heard anything about it? Does anyone know how to configure the termination port on the switch itself? Should the switch port that terminates the TLS/EPL circuit be configured a sa normal full duplex Ethernet access port or as a trunk port? Would be an L2 or L3 connection?

Any input you may have will be helpful, Im sure. HELP!! :-)

TLS is usually delivered either half-duplex or full-duplex depending on the provider. Your termination point would be a L3 router Ethernet port or firewall ethernet wan port. It was typically only available to Federal agencies and is considered "old technology"

EPL I gather from reading the brochure, is more of a replacement for a private line T1 where you own the CPE at both ends. In this case, it is a L2 connection between your two sites vs a L3 connection over a T1.

It really depends on what your goals and needs are. Are you looking for direct Ethernet to the Internet, or between your own sites?
 Most carriers do have some kind of MetroEthernet, FIOS, EPL type service in most major cities.
