5.10  DS-3 Configuration Page 

 
This page allows the administrator to selectively enable or disable the DS3 interface. If the DS3 
interface is not going to be used, it should be disabled so that alarms are turned off and so that 
more throughput is allocated to the Ethernet interface. With the DS3 input enabled, even if there 
is no DS3 signal present, the aggregate throughput of the Ethernet interface is reduced by 
roughly 89.5Mbps. 
 

Certain combinations of TDD Frame Size, Link Distance and Bandwidth will 
limit if the DS3 interface can be carried by the radio. In these cases, the selection 
on the DS3 Interface Configuration page will not be available. 

 
The DS3 Configuration Page allows the administrator to enable/disable the DS3 interface. Also, 
AIS (alarm indication signal) may be enabled/disabled. If enabled, the radio will place an AIS 
code on the output of the associated interface if/when the link fails or there is no DS3 signal 
available from the far end to provide the user at the local end.

5.11  File Transfer Page 

The File Transfer Page allows the administrator to upload and download files to and from the 
radio. Uploading files will place these new files in a reserve memory space. After files are 
uploaded the File Activation Page is used to enable these files. Uploading files does not 
automatically enable them.
