- Maximize the performance of copper wire with higher speed and longer coverage distance
- Provides 2-pair, 4-pair and 8-pair bonding with symmetric bandwidth of up to 45 Mbps
- The best replacement solution for legacy and expensive lease lines

Ethernet-in-the-First-Mile (EFM), also known as IEEE 802.3ah, is a matured technology for delivering symmetric bandwidth to businesses, government offices and organizations with multiple locations (multiple-site). It allows continuous standard Ethernet network to reach across the globe, eliminating non-native transport such as Ethernet over ATM from the access networks. EFM delivers up to 5.7 Mbps per line with standard equipment supporting up to bonding — a relatively high-performance connection with up to 45 Mbps bandwidth symmetrically with high stability, low delay and low packet loss.

Today’s carriers are eager to connect business customers to their metro networks. The G.SHDSL.bis EFM technology is the best solution for enterprises with the demand to a certain amount of transmission over symmetric bandwidth. It has advantages of maximizing the performance of copper wire with higher speed and longer distance coverage. By leveraging pre-installed bundles of twisted-pair cable to deliver the first-mile broadband network access, ZyXEL bonded G.SHDSL.bis with EFM solution to smoothen the issues of fiber-optic cable installation. In addition to offering different bandwidth packages by using the G.SHDSL. bis bonding technology, this is the best solution that enables carriers to expand service offerings in high-margin enterprise markets.

The use of IP over Ethernet in subscriber access applications eliminates unnecessary network layers. It reduces the number of elements on a network as well as the equipment, operational and complexity costs. Simple architectures are always easier to manage, especially in complicated central environments. In the first mile, native Ethernet on copper or optical fiber networks will provide significant cost advantage over other technologies. These IP/Ethernet networks can coexist with Time-Division Multiplexing (TDM) services.

ZyXEL’s P792 G.SHDSL.bis Series complies with the ITU-T 991.2 G.SHDSL, G.SHDSL.bis and IEEE 802.3ah standards and offers superior Ethernet connection reliability with unmatched rate and reach. The P-793H Series and P-794H complies with ITU-T G.998.1 (G. Bond) and supports 4-wire/8-wire bundle for higher bandwidth and longer distance. With ZyXEL’s End-to-End G.SHDSL.bis with EFM Solution for business customer edge on customer premises, service providers can quickly and cost-effectively introduce profitable broadband services to businesses, governments, schools and other organizations by fulfilling the demand for higher bandwidth with manageable cost.
