1.2  INTRODUCTION TO CANOPY T1/E1 MULTIPLEXER 
This user guide provides the installation and configuration requirements for the Canopy 
T1/E1 Multiplexer, a modular gateway that works with Canopy Backhaul Modules to 
enable up to four T1 (or up to three E1) circuits to be extended over Ethernet networks.   
The Canopy T1/E1 Multiplexer is available in two power configurations: 
◦ 
an external 3.3-v DC power source from a 120/240-v AC adapter (supplied  
by Canopy) 
 
 
WARNING! 
An external AC surge suppression device must be used with the Canopy 
T1/E1 Multiplexer. For infrastructure installations, Canopy Engineering 
recommends an AC line surge suppression unit that meets the standard 
IEC 801-5 (EN61000-4-5) Maximum Surge Voltage (1.2x50µsec) 6 KV.
 
 
◦ 
a connection to an external 
−48 v DC supply. 
The Canopy T1/E1 Multiplexer is illustrated with Canopy Backhaul Modules (BHs) in
