Quick Eagle Networks Network Router 4200 SDSL User Guide

4200 SDSL Ethernet Bridge  
Cost-effective Ethernet over Copper solution to  
extend LANs over three copper pairs at 7 Mbps.  
Main Features:  
Quick Eagle's 4200 SDSL Ethernet BridgeTM offers you up to 7 Mbps  
symmetrical bandwidth on three pairs of copper loops for distances up to  
11,000 feet (or 480 Kbps for up to 25,000 feet).  
Leverages existing copper infrastructure  
Comes with built-in redudancy for  
critical applications  
The 4200 SDSL Ethernet Bridge can be deployed in two main ways: You can  
configure the 4200 SDSL Ethernet Bridge to bond all three SDSL links in a  
single multilink bundle to leverage load balancing and link resiliency. Using  
frame-based multiplexing the unit load balances traffic across the links to triple  
your bandwidth. When a link is out of service, the unit carries traffic on the  
remaining active links. The unit also detects when a link is operational and  
adds it back automatically to the multilink bundle.  
Supports higher bandwidth by  
“multilinking” up to three pairs of copper  
Offers independent links to different  
locations  
Supports Spanning Tree Protocol (STP)  
2B1Q line coding  
Symmetric transmission (SDSL) from  
480 Kbps to 7 Mbps  
You can also configure the 4200 SDSL Ethernet Bridge to link the three copper  
pairs to different locations. For instance, transportation agencies can take  
advantage of the 4200 SDSL Ethernet Bridge's unique feature set to manage  
outdated traffic light systems, leveraging their existing copper infrastructure  
between different intersections and avoiding the cost of deploying Fiber to  
achieve Ethernet-based services such as video monitoring.  
10/100 Ethernet port  
Transparent learning bridge  
Transparent to VLAN (802.1 Q) label  
tags  
Embedded SNMP agent  
The 4200 SDSL Ethernet Bridge uses a learning MAC Bridge to transparently  
forward packets from one LAN to another over the SDSL links.  
RMON-2 performance monitoring  
enables visibility across the entire  
protocol stack for increased network  
reliability  
In addition, the 4200 SDSL Ethernet Bridge offers extensive remote management  
capabilities, including in-band management on its Ethernet data port or SDSL  
port for simultaneous SNMP, Telnet, Ping, and TFTP management access.  
In-band management for plug-and-play  
installation and troubleshooting
