is limited.
TABLE 11.3 Application Fits for EoS and MSPPs
312 Chapter 11
Benefits and Shortcomings
Given the market drivers for Ethernet over SONET and the key applications where
this technology and MSPPs should (or should not) be used, this section summarizes its
benefits and shortcomings from the perspective of a service provider.
Benefits
The main benefit of EoS lies in its ability to enable Carrier Ethernet services. Carrier
Ethernet services represent new revenue potential for service providers who provide
either rudimentary Ethernet services based on enterprise-grade network technology
or no Ethernet services at all.
An example from the wireless world illustrates the benefits of Carrier Ethernet services
and the potential role of EoS. Most wireless service providers lease traditional
DS1 circuits from their cell tower or base station locations to their mobile telephony
switching offices (MTSOs). The incumbent wireline carrier typically provides the wholesale
leased DS1 services.
Wireless providers lease DS1s from ILECs for several reasons. First, their base
stations and MTSO equipment, while featuring a mix of technologies including Time
Division Multiple Access (TDMA), Global System for Mobile Communications (GSM),
and Universal Telecommunications Mobile System (UMTS), typically provide DS1 network
interfaces.
