But Mid-Band Ethernet has the benefit of using the in-place copper plant??”you don??™t
have to dig, wait, or build new serving sites. It allows the carrier to leverage what is already
in place to deliver better services and get more revenue today without heavy investment.
Typical Deployment Scenarios
The techniques for deploying Mid-Band Ethernet are pretty straightforward. Because
the copper plant is already in place, deployments must fit the existing copper plant
architecture.

There is generally a piece of equipment located at the customer site that terminates
the copper pairs and translates the Mid-Band Ethernet to a more traditional LAN variety
of Ethernet (e.g., a 10/100BASE-T port). There is also a piece of equipment that
resides at the serving office, which aggregates multiple customers together and performs
translation between the carrier Ethernet network and the Mid-Band Ethernet
access network.
The variety in the deployments comes from where the serving office is located and
where the customer demarcation is located. Figure 5.4 shows multiple scenarios. The
serving office could be a carrier??™s central office equipment, a remote terminal, or a wiring
closet in the basement of a building.
