Chapter 1: description and requirements chapter 1: description and requirements the e3switch converters described herein are used individually to connect a customer's ethernet lan to an isp offering ppp over full or fractional/subrate ds3. The lan interface is pppoe rj45 100/1000basetx copper or sfp...

Chapter 2: quick set-up attach an ethernet utp5 cable from the pppoe lan port on your equipment to the rj-45 lan port 2 of the converter. The converter can perform automatic cross-over vs straight-through cable adaptation. The lan 2 light will change from orange to green if a properly negotiated eth...

Chapter 5: operating modes and configuration packet flow port to port packet flow lan-to-lan certain firmware versions allow lan-to-lan packet flow to be enabled, if desired, in units where the second sfp/lan port has been enabled/purchased. Lan-to-lan unidirectional flow for monitoring may also be ...

Chapter 5: operating modes and configuration 1000mbit/s is generally preferred over 100mbit/s on the pppoe port only, though it generates significantly more power-requirements, heat, and radiated electromagnetic noise even in the absence of packet flow. 1000mbit/s may slightly reduce path latency, a...

Chapter 5: operating modes and configuration ds3/e3 return to service delay the return-to-service delay prevents network topology thrashing if a telecom link is flapping up and down. Some telecom carriers will interrupt service for 50msec, once per day as a link test. A configurable, failure- time s...

The maximum length of each cable shall be 440 meters for e3 or 300 meters for t3/ds3, but the acceptable cable lengths of equipment attached to the converter must be met as well. For lengths over 135 meter...
