IpLink™ Model 2888
Multi-Megabit Inverse Mux
Transparent Ethernet Bridging of large Ethernet frames and jumbo Ethernet frames over Bonded T1/E1 circuits for Transparent Ethernet Backhaul
Product Description
The Model 2888 Multi-Megabit Inverse Mux is a managed Ethernet bridge with two (2) Gigabit Ethernet ports and either two (2) or four (4) T1/E1 ports. The Inverse Mux transports jumbo Ethernet frames over bonded T1/E1 circuits using Multi-link PPP, creating up to an 8 Mbps transparent Ethernet connection over a TDM based infrastructure network. Complete with Layer 2 filtering, Layer 2 traffic shaping and Active Layer 2 QoS, the Model 2888 enhances a carrier’s rapid service deployment capability when interconnecting NGN equipment or backhauling broadband traffic.
Who is it for?
The Model 2888 Multi-Megabit Inverse Mux is designed for facilities based Tier I carriers with developed TDM networks or other service providers with access to wholesale T1/E1 circuits that need to rapidly expand Transparent Ethernet backhaul in areas where the network infrastructure is not yet in place due to a lack of fiber or other backhaul facilities.
Position Statement
For carriers needing to backhaul Ethernet traffic from IPDSLAMs and 3G cell sites, the IpLink™ Multi-Megabit Inverse Mux transparently carries large Ethernet frames over bonded T1/E1 circuits. Unlike other solutions, which do not support jumbo Ethernet frames, the Multi-Megabit Inverse Mux transparently passes ALL jumbo Ethernet frames to simplify configuration while applying ACTIVE Layer 2 QoS traffic shaping and filtering.
