Transparent Ethernet Bridging of large Ethernet frames and umbo

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.

Product Brief

Solution Description

Rapid service deployment is the key to grabbing

market share, the lifeblood of carrier business

economics. At times the infrastructure needed to

support end user services is not in place, creating

delays that cost millions in long-term lost revenues. To

overcome these ills carriers with access to wholesale

T1/E1 circuits can reuse the TDM network to bridge

the bandwidth gap and continue deploying NGN

services in areas where the infrastructure is developing.
