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.
How MPLS Replaces Frame Relay Networks
Frame relay has been a popular private WAN networking service to link multiple locations. MPLS is the replacement service that offers more flexibility, higher bandwidth and lower costs.
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.
Advantages of Voice over MPLS
MPLS networks have the quality of service features needed to insure low levels of latency, jitter and packet loss to ensure high quality voice transmission. You avoid toll charges by keeping your internal phone calls on the MPLS network that connects your various business locations.
MPLS Network Speeds
MPLS networks can run at any network speed and are being adopted by major carriers as the multipoint to multipoint technology of choice. For this reason, MPLS is fast replacing Frame Relay.
