Designates the data rate for the port. Available selections depend on the current base
rate configured for the port. The factory default for Nx64 is 384 kbps, and Nx56 is
336 kbps.
NOTES: – This selection is not available if the individual channel allocation method
(Channel) is selected using the Assign By field.
– Changing this selection from one rate to another deallocates all DS0
channels assigned to either the network interface or the DTE
Drop/Insert (DSX-1) interface.
– When you enable EDL, 8 kbps of the total bandwidth allocated for this
port is not available to the synchronous data port. For example, if you
select 256 kbps and EDL is enabled, only 248 kbps are available.
– When you enable EDL on a synchronous data port and the clock source
is set to that synchronous data port, the external device must provide a
clock of 8 kbps less than the expected data port rate. For example, if
you select 64 kbps, the external clock source must supply a 56 kbps
clock signal.
