What is Ethernet over Copper Access?
Ethernet over Copper, or EoC, uses copper transmission lines rather
that fiber optics. By using a proprietary modulation scheme, existing copper telco pair can be bonded to transport Ethernet bandwidths from 3 to 50 Mbps.
What is a Service Level Agreement?
An SLA or Service Level Agreement is often part of the contract
between a business and telecom carrier for line or network services.The SLA spells out the expected availability
of the service and what penalties the carrier is liable for downtime or parameters out of spec.
Don't Frame Relay Networks Do The Same Thing as MPLS Networks?
They used to in a simpler way. Frame relay networks use small ATM cells rather than the modern IP network cores of MPLS networks, so they tend to be less efficient. Most carriers are shutting down their Frame Relay networks since the rise of MPLS. The newer MPLS networks tend to be designed for higher speeds to match today's business bandwidth needs.
How MPLS Enables VoIP
Enterprise VoIP phone systems offer performance and cost savings advantages to businesses, but only if voice quality can be maintained. MPLS networks are specifically designed to maintain voice packet integrity.
MPLS Network Configurations
The MPLS network can be thought of as a cloud that is accessible from many locations. Your service can be set up for a single point to point connection, a hub and spoke replacement for central offices serving many remote locations, or a fully meshed network where any site can communicate with any other site.
