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.

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.

Unique Selling Position
The IpLink™ Model 2888 Multi-Megabit Inverse Mux is the only transparent Ethernet Bridge offering BOTH jumbo
Ethernet frame and Active Layer 2 QoS at a fraction of the cost of other solutions.
