transmit data up to 45 Mbps. Although considerably more expensive than a T1 connection, larger businesses may need a T3 connection to accommodate the number of employees. Large businesses with multiple locations might use a combination of T1 and T3 lines. E3 is a European standard that transmits data at 34.368 Mbps.
Metro Ethernet:
offers a wide range of high-bandwidth options, including Gbps links. Large companies with many branches in the same city, such as banks, use Metro Ethernet. Metro Ethernet connects the main office location and all the branches using switched technology. Metro Ethernet allows the transfer of large amounts of data faster and less expensively than other high-bandwidth connection options.
