DS1 wholesale services are also widely available. These services typically
feature guarantees on important service-level parameters such as service availability
(i.e., uptime) and end-to-end latency.
Wireless network equipment, however, is transitioning to Ethernet. The emerging
generation of equipment (e.g., based on UMTS Release 5) will provide network interfaces
based on IP/Ethernet, not DS1 technology. Wireless providers will look to incumbent
wireless service providers to offer wholesale Ethernet leased-line services. When
they do, they will want services that are consistent and widely available. They will
also demand Ethernet services that provide guarantees for high service availability
and low end-to-end latency. This provides an opportunity for wireline carriers to offer
wholesale Carrier Ethernet services, especially those services that accentuate the key
attributes of standardized services, reliability, and QoS. As discussed previously, these
three Carrier Ethernet attributes fall into the ???sweet spot??? of EoS solutions.
Moreover, the transition to UMTS Release 5 and IP/Ethernet will take time, as will
the growth of Carrier Ethernet services to match the near-ubiquity of DS1 leased-line
services.
