ft3
Use ft3 to configure a CT3 interface to operate in the FT3 mode and set the DSU mode or the subrate.
Use undo ft3 to restore the default.
Syntax
ft3 { dsu-mode { 0 | 1 | 2 | 3 | 4 } | subrate number }
undo ft3 { dsu-mode | subrate }
Default
DSU mode 0 (the Digital Link mode) is adopted, and the subrate is 44210 kbps.
Views
CT3 interface (in FT3 mode) view
Default command level
2: System level
Parameters
dsu-mode: Specifies the FT3 (Fractional T3) DSU mode for a CT3 interface operating in FT3 mode. This
keyword can be followed by 0, 1, 2, 3, and 4.
0: Specifies the Digital Link mode, where the subrate is a multiple of 300746 bps and is in the range of
300 to 44210 kbps (in other words, up to 147 rate levels are available).
1: Specifies the Kentrox mode, where the subrate is a multiple of 1500000 bps and is in the range of
1500 to 35000 kbps. In this mode, the subrate can also be 44210 kbps (making a total of 57 subrate
levels).
2: Specifies the Larscom mode, where the subrate is a multiple of 3157835 bps and is in the range of
3100 to 44210 kbps (in other words, up to 14 subrate levels are available).
3: Specifies the Adtran mode, where the subrate is a multiple of 75187 bps and is in the range of 75 to
44210 kbps (in other words, up to 588 subrate levels are available).
4: Specifies the Verilink mode, where the subrate is a multiple of 1578918 bps and is in the range of
1500 to 44210 kbps (in other words, up to 20 subrate levels are available).
subrate number: Specifies the subrate for the CT3 interface. The number argument is in the range of 1 to
44210 (in kbps).
Usage guidelines
FT3 (Fractional T3 or Subrate T3) mode is a non-standard E3 application mode. In this mode, the subrate
level setting varies with vendors. You can use the ft3 command to make the device to be compatible with
devices of other vendors operating in specific FT3 DSU modes.
This command is only applicable to CT3 boards that support FT3.
This command is only available in CT3 mode.
As for the ft3 subrate command, the actual subrate usually is not exactly the one set by the command.
After you set the subrate by using the ft3 subrate command, the T3 interface searches the subrate levels
corresponding to the DSU mode it is operating in and selects the one that is closest to that set by the
command as its subrate. The device then adjusts the hardware to allow for the subrate.
