The Model 2888 Multi-Megabit Inverse Mux is a transparent Ethernet
bridge with two (2) Gigabit Ethernet ports and either two (2) or four (4)
T1/E1 ports. The Inverse Mux transparently extends Ethernet/IP over
bonded T1/E1 circuits, creating up to an 8 Mbps Ethernet connection.
Complete with Layer 2/3 filtering, traffic shaping and Active QoS, the
Model 2888 enables the delivery of multi-service access over existing
facilities to enterprise subscribers outside the range of DSL and fiber.
The Model 2888 Multi-Megabit Inverse Mux is designed for
Tier I carriers that own TDM networks or alternative service
providers with access to wholesale T1/E1 circuits. Service
providers using the Multi-Megabit Inverse Mux can offer highspeed access service over existing facilities in areas where the
network infrastructure, such as fiber and DSL, is not yet in
place. They can also provide known TDM based packet
services to those subscribers resisting the adoption of emerging
broadband technologies.

Multi-Megabit Inverse Mux
Carrier Access Bandwidth
For service providers needing to deliver symmetric IP or Ethernet access at speeds greater than a single T1/E1 but less
than a T3/E3, the IpLink™ Multi-Megabit Inverse Mux transparently bridges Ethernet over bonded T1/E1 circuits. Unlike
other solutions that require difficult routing configurations, the Inverse Mux offers simple high-speed Ethernet transport
over established TDM infrastructures.

FAQ
s
Rapid service deployment is the key to grabbing market share, the lifeblood of carrier business economics. Sometimes
the infrastructure needed to support subscriber services is not in place, creating delays that can cost millions in long-term
lost revenues. Other times subscribers prefer to avoid emerging technologies. To combat these ills carriers with
inexpensive T1/E1 circuits can reuse the already installed TDM network to bridge customer Ethernet traffic, avoiding
endless hours of complex IP routing configurations and providing their subscribers a right-sized service.

The IpLink™ Model 2888 Multi-Megabit Inverse Mux provides broadband Ethernet/IP bandwidth over existing TDM
circuits, increasing service deployment speed and reach, reducing configuration complexity, and enabling low-cost
immediate service roll-out without changes to the network infrastructure.

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.
