IpLink Model 2888 Overview
The Model 2888 Four-Port T1/E1 Multi-Megabit Inverse Multiplexer (figure 2) provides point-to-point high-
bandwidth Ethernet/IP connectivity over TDM-based T1/E1 circuits. Dual 10/100/1000 Ethernet ports
ensure easy connection to any LAN infrastructure.
In order to maximize the bandwidth utilization over the T1/E1 links, the Multi-Megabit Inverse Mux uses
Multi-Link PPP to bond the individual circuits into one high bandwidth WAN link. Ethernet/IP traffic is
transparently bridged over the link using PPP/BCP which adds minimal encapsulation overhead when com-
pared to ATM.
Key features make the Multi-Megabit Inverse Mux an ideal solution for VLAN trunk extension. The Inverse
Mux supports IEEE 802.1p/Q VLAN tagging and priority. VLAN tagged traffic that is received on any of the
Gigabit Ethernet interfaces is transparently transported over the WAN to the matching Inverse Mux on the
other side. The VLAN priority bits are inspected and the QoS of the individual Ethernet frames are preserved
end-to-end. The Multi-Megabit Inverse Mux likewise supports VLAN tagging of Ethernet traffic.
ACLs allow Layer 3 filtering and Layer 3 based QoS of the VLAN and bridge connections. Filter by IP address,
IP port or even protocol. Use the ACL to force an inspection of the ToS/DiffServ bits and preserve end-to-end
QoS.
The 2888 Model Series boasts easy installation, offering CLI configuration via Console/VT-100 or Tel-
net/SSH, HTTP web based management, and SNMP. Patton's series of high-speed access routers offer the ver-
satility and reliability demanded for business-class applications at the most affordable price..
