Multidwelling or Ethernet-to-the-Subscriber Network

Metro Ethernet provides the access technology for service providers deploying voice, v ideo, and Internet
access services to metropolitan areas. The Metro Ethernet user-facing provider edge (UPE) switches
provide economical bandwidth and the security and the QoS needed for these services.
Figure 1-1 shows a Gigabit Ethernet ring for a residential location, serving multitenant units by using
Cisco ME 3400 Ethernet Access switches connected through 1000BASE-X SFP module ports. Cisco ME
switches used as residential switches provide customers with high-speed connections to the service
provider point-of presence (POP).
Home access gateways are connected to the ME switches through UNIs configure d as 8 02. 1Q t runks.
Because the default behavior on UNIs allows no local switching between UNI ports, the subscribers are
protected from each other. UNIs also do not process control protocols from customers, so
