Patton's EFM Equipment for Carriers and Enterprises Shipping Now

Patton (News - Alert) has announced that it is now shipping its RocketLink Model 3202 G.SHDSL Ethernet-in-the-First-Mile (EFM) modem for carriers, service providers and enterprises.

The Gaithersburg, Md.-based provider of business and carrier-class VoIP, network access, connectivity and video-surveillance equipment, began taking orders in September from service providers who want to roll out profitable broadband Ethernet services to businesses, governments and schools, said Patton representatives.

“Inquiries are coming from all sorts of customers, from clean transmission environments -- like business LAN extension -- to noisy railway car applications,” said Johnnie Grant, EFM product manager at Patton.

During the past two months, the Maryland-based manufacturer said it has seen a steady and growing interest in the product. By leveraging pre-installed bundles of twisted-pair cable to deliver first-mile broadband network access, Patton’s EFM Network Termination Unit eliminates the trouble and expense of installing fiber-optic cable, Grant said.

“It preserves capital investment,” Grant said. “With Patton’s EFM modem, operators can use the infrastructure they already have to deliver new, revenue-generating services.”

Using Ethernet-over-SHDSL (EoSHDSL), The RocketLink 3202 extends connections up to 1.6 miles/2.6km at symmetrical nx64 rates up to 22.8 Mbps. The device employs “EFM Bonding” to combine up to four copper pairs (eight wires) into a single communications channel. With an on-board four-port fast-Ethernet switch with QoS, CoS and VLAN (802.1q), the RocketLink 3202 supports four levels of traffic priorities, flow control and rate control.

“Service providers like the 3202, because they can offer premium high-speed symmetrical data services to customers they couldn’t reach with older G.SHDSL equipment,” Grant said. “Today’s carriers are eager to connect business customers to their metro networks, and EFM is the key standard that makes this migration easier. ADSL2 is an inexpensive long-reach technology, but it’s asymmetrical. VDSL2 is blazing fast but has very limited distances, especially in symmetrical configurations.”

Calling it the “ideal gap filler,” Grant noted that Patton’s model 3202 is compliant with ITU-T G.991.2 and IEEE (News - Alert) 802.3ah and offers the reliability of Ethernet connectivity with unmatched rate and reach. Patton’s G.SHDSL EFM is the ideal gap filler.

“EFM enables standardization and Ethernet penetration into the access networks,” Grant said. “Eventually EFM will eliminate non-native transport methods such as Ethernet over ATM.”
