SETTING THE DATA RATE
The HDSL Mode setting determines the data rate. Depending on the mode
you want to set, continue with either “Standard Mode Data Rates” or
“Extended Mode Data Rates.”
Standard Mode Data Rates
In Standard HDSL Mode, the HDSL line always operates at a constant rate,
however the Fractional Interface Card can be set to operate synchronously at
integer multiples of either 56 kbps or 64 kbps (n x 56 kbps or n x 64 kbps). In
addition, the Fractional Interface Card can also be configured to operate at
“full rate,” where all the user bandwidth of the HDSL line is made available
to the data port.
Some options, such as the HDSL Rate must be the same for
both the local and remote unit. Resetting the Campus unit
configuration values on one unit only, may cause the HDSL
link to go down.
