[Sysname-Cpos2/0/0] e3 1 shutdown
fe3
Use fe3 to configure the specified E3 channel to operate in FE3 mode and configure its FE3 DSU mode
or FE3 subrate.
Use undo fe3 to restore the default DSU mode or subrate.
Syntax
fe3 e3-number { dsu-mode { 0 | 1 } | subrate sub-number }
undo fe3 e3-number { dsu-mode | subrate }
Default
For an FE3 channel, the DSU mode is 1 (Kentrox) and the subrate is 34010 kbps.

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 Table 30.
W
hen 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
