10 Mbps Metro Ethernet more cost effective than 6 Mbps ATM

Metro Ethernet provides a migration from the typical bottleneck of bringing multiple remote sites back to a main site on T1 circuits.

Re: Inhibitors for Metro Ethernet adoption.

In the past the options were T1 or DS-3. This was usually too little or too much with the option being multiple T1 host circuits With Metro Ethernet the host circuit can be 10, 20, 50 meg with (in some cases) T1 circuits pulled back to the host at full bandwidth instead of sharing a T1 host or multiple T1 hosts. If higher Bandwidth is needed at any remote site, again Metro Ethernet allows 10, 20 .. Mbps connectivity back to the main site. This is a breakthrough which allows necessary bandwidth to be considered. The cost we find has a breakpoint above 3 Mbps ATM. The next option cost-wise is 10 Mbps Metro Ethernet, cheaper than 6 Mbps ATM-IMA. ( With some providers the Frame Relay T1s can be pulled back to the Metro Ethernet host at the main site.)
