subrate sub-number: Sets the FT3 subrate, in the range of 1 to 44210 kbps.
Usage guidelines
FT3 (also called subrate T3) is a non-standard T3 application. Available FT3 subrate ranges and the
number of subrate grades vary with vendors. You can use the ft3 command to configure your device to
be compatible with the FT3 DSU modes listed in
When you use the ft3 command, note the following:
The subrates available in the DSU mode set with the ft3 dsu-mode command are discrete and the
•
subrate set with the ft3 subrate command is approximate rather than exact. After you set a subrate,
the T3 interface works out the precise subrate (in bps) closest to the approximate subrate within the
subrate range available in the specified DSU mode. This calculated precise subrate is the one
actually applied to the hardware circuit.
You can use the display interface serial interface-number:0 command to display the DSU mode,
•
configured subrate, actual rate, and baud rate of a T3 interface. The actual rate of the T3 interface
is the pure data bandwidth excluding the bandwidth for overhead bytes. The baud rate of the T3
interface, 44736 kbps, is the actual rate of the T3 circuit, including the bandwidth for the overhead
bytes.
Examples
# Configure T3 channel 1 on interface CPOS 2/0/0 to operate in DSU mode 3 and set its rate to 3000
kbps.

link-delay

Use link-delay to set the physical state change suppression interval on a CPOS interface. In case of an
up or down event, the CPOS interface comes up or goes down after the physical state change
suppression interval.
Use undo link-delay to restore the default.
