3.0 Purpose and Goal
This document describes proper setup and configuration of both Canopy backhaul
elements and the TMUX devices.
Additionally this document illustrates the importance of maintaining reasonable
expectations for the demanding circuit emulation application over a packet infrastructure.
Circuit emulation can never be as good as a “real circuit.” Traditional circuit performance
metrics can only approach that of a terrestrial-based circuit from a telephony common
carrier.
4.0 Optimum Backhaul and TMUX Configuration:
Circuit emulation, the process of converting PBX traffic to wireless Ethernet and back,
requires the installer to follow documented best practices learned from various lab
testing, field trials and customer installations to achieve a bit error rate (BER) equal to or
better than 10

This section provides two quick start diagrams with the Canopy configuration
parameters* that must be set in order to achieve an optimum configuration. This section
is followed by “Optimum Configuration Details” that further details using the Canopy
System for T1/E1 replacement.
