9 T elecom providers can now offer a range of cost- effective Ethernet hand-offs to dealers of all types and sizes. Service providers have worked hard to leverage existing technologies to offer wide rang- ing options of scalable Ethernet to the ever chang- ing marketplace, providing the bandwidth punch needed to operate effectively, while allowing for scalability. Ethernet over Copper (EoC or EoCu) Ethernet over Copper solutions utilize non-repeated twisted pair. Loops are provisioned comparably, if not identically to ADSL loops. Multiple loops are combined into customer premise Ethernet aggregation devices giv- ing end users a single Ethernet handoff. Loops/speeds are distance sensitive, and SLAs are network-based only (not last mile based). EoC is typically the most cost-effective Ethernet product available to end users. Maximum speeds differ from provider to provider, but max throughputs of 45mbps symmetrical are available. Ethernet over DS1 (EoDS1) Similar to EoC, multiple loops are provisioned and aggregated into a customer premise Ethernet device, only this time the loops are standard DS1. Since stan- dard DS1 is repeatable, EoDS1 is not subject to distance limitations of EoC. While typically higher priced than EoC, SLAs are inclusive of the DS1 local loop of 4 hours. Maximum speed tops out at 10mbps symmetri- Q bandwidth options — continued on page 10 Bandwidth needs for Auto Dealers is increasing. As firms like DealerTrack or Reynolds & Reynolds are migrating their CRM software packages to cloud-based environments, the Auto Dealers are needing more bandwidth beyond the simple Internet DS1 1.5mbps.
