Ekinops Offers Backhaul Solution for DSLAM Networks
By Laura Stotler, TMCnet Contributing Editor
Ekinops has announced a new backhauling solution for DSLAM networks that broadens the company’s aggregation product line by offering increased multi-protocol support and ADM functionality. Based on the PM 1008 DC, which is optimized for DSLAM and 3G mobile backhauling as well as for Metro DWDM networks, the new solution accommodates high-capacity Ethernet links as well as ATM uplinks.
Ekinops is a provider of DWDM, optical transport and aggregation solutions. The new backhauling solution combines benefits of backhaul solutions like SONET/SDH ADMs, WDS systems and 10 Gigabit switches while also offering significant cost savings to carriers. By deploying additional DSLAMs and employing more flexible backhaul solutions, carriers may roll out high-bandwidth services like IPTV ( News - Alert) and VOD.
The new solution uses TDM to aggregate a combination of multiple GbE, OC-3/STM-1 and OC-12/STM-4 signals over one OC-192/STM-64 wavelength. It can then employ WDM to multiplex a number of wavelengths on one fiber. Each wavelength on the network can aggregate multiple and different protocols like GbE, FE, fiber channel, OC-3/STM-1, OC-12/STM-4, OC-48/STM-16 and OC-192/STM-64. Multiple units may be daisy chained to create metro rings, and signals may be added and dropped at each site. The use of aggregation reduces the number of wavelengths in the network and offers a low cost solution.
"Carriers are now deploying their second generation DSLAMs, which have Gigabit Ethernet uplinks," said Didier Bredy, Ekinops' CEO. "Ethernet switches were initially considered as a backhaul option, but for a backhaul solution to be effective it must also handle the ATM uplinks that are common on first generation DSLAMs. Our flexible platform supports both kinds of interfaces and helps carriers support their legacy and future applications at wire-speed."
"Ekinops has developed an elegant solution to backhauling," said Eve Griliches, research manager for IDC. "Aggregating both GbE and ATM on the same wavelength provides a migration path for traditional DSLAMs as well as supporting IP DSLAMs at very low cost points compared to alternative approaches."
