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. Complete with Layer 2/3 filtering, Layer 2/3 traffic shaping and
Active Layer 2/3 QoS, the Model 2888 enhances an enterprise’s ability to
address the Wide Area Network (WAN) bandwidth requirements of most
Ethernet applications.
The Model 2888 Multi-Megabit Inverse Mux is designed to bridge the Ethernet/IP bandwidth gap between a single
T1/E1 and a T3/E3. Bandwidth hungry applications such as database/Intranet, VoIP and surveillance video over IP that
need to be transported over the WAN will benefit from a resilient multi-circuit solution.
IpLink™ Model 2888
Multi-Megabit Inverse Mux
Transparent Ethernet Extender over Bonded T1/E1 Circuits
For enterprise IT Managers needing to bridge the
bandwidth gap between a single T1/E1 and a T3/E3,
the IpLink™ Multi-Megabit Inverse Mux transparently
transports Ethernet over bonded T1/E1 circuits.
Unlike solutions from Cisco and others, which are
difficult to configure, the Multi-Megabit Inverse Mux
makes it easy to transparently pass ALL Ethernet
frames over the WAN while applying ACTIVE Layer
2/3 QoS, traffic shaping and filtering.

FAQ

As enterprise IT managers leverage the convergence of voice, video and data over Ethernet, the need to transport
Ethernet over the WAN at speeds greater than a single T1/E1 increases. Avoid switching to an expensive T3/E3 circuit,
transitioning to an unproven Ethernet based WAN service or spending endless hours configuring IP routing redundancy.
Use the Model 2888 to bond multiple T1/E1 circuits and increase point-to-point Ethernet bandwidth without
overcomplicating configurations or sacrificing resiliency.

The IpLink™ Model 2888 Multi-Megabit Inverse Mux increases point-to-point Ethernet/IP bandwidth over standard
T1/E1 circuits, reducing configuration complexity, and providing active QoS for real-time application requirements.

balance outbound traffic only. To get bidirectional load balancing requires complex configuration at both ends.
Secondly, both routers must be configured to assign the same administrative distance and cost to a destination. Lastly,
load balancing at the IP packet layer creates a situation where packets can reach the destination out of order, creating a
problem for streaming media such as video. By using Ethernet bridging and relying on ML-PPP, the configuration is
simplified and the out of order packet problem eliminated.
