8.3.1.6 Telecoms Configuration Page
The Telecoms page is only available when the Telecoms Interface has been set to either E1
or T1 in the Installation Wizard.
It displays the interface setting and line code for the available telecoms channels. The
Canopy 150/300 Mb BH is able to support two E1 or T1 channels. However, in the Canopy
150 Mbps Backhaul configuration one of these channels is disabled. The channels are
referred to as "Channel A" and "Channel B".
The "Channel B" configuration and controls will be displayed only when the second channel is
enabled.
Telecoms Interface may be either E1 or T1, reflecting the Installation Wizard setting.
Line Code Displays the Line Code setting for each channel. The Line Code configuration
must match the configuration of the connected equipment and may be set using the
Installation Wizard.
Cable Length The Cable Length setting is applicable in T1 mode only and shows the cable
length specified in the installation wizard.
Loopback Allows the E1 or T1 data stream to be looped back at the copper or wireless
interface. During normal operation the loopback must be set to "None".
It may be helpful during installation to test the telecoms links by performing loopback
connections.
A "Copper" loopback connects the received data on a given telecoms interface to the
transmit. A "Copper" loopback may be used, in conjunction with an appropriate test unit, to
confirm that the correct connections have been made to the ODU.
