Usage guidelines
FE3 (also called subrate E3) is a nonstandard E3 application. Available FE3 subrate ranges and the
number of subrate grades vary with vendors. You can use the fe3 command to configure your device to
be compatible with the FE3 DSU modes listed in
When you use the fe3 command, note the following:
• The subrates available in the DSU mode set with the fe3 dsu-mode command are discrete and the
subrate set with the fe3 subrate command is approximate rather than exact. After you set a subrate,
the E3 interface works out the precise subrate (accurate to 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 an E3 interface. The actual rate of the E3 interface
is the pure data bandwidth excluding the bandwidth for overhead bytes. The baud rate of the E3
interface, 34368 kbps, is the actual rate of the E3 circuit, including the bandwidth for the overhead
bytes.
Examples
# Configure E3 channel 1 on interface CPOS 2/0/0 to operate in DSU mode 1 and set its subrate to
500 kbps.
