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
Figure
