Use the no version to remove the text description or alias.
See description.
Use to enable cell scrambling in a T3 ATM interface.
Example
host1(config-controll)#ds3-scramble
Use the no version to turn off cell scrambling on the interface.
See ds3-scramble.
Use to enable cell scrambling in an E3 ATM interface.
Example
host1(config-controll)#e3-scramble
Use the no version to turn off cell scrambling on the interface.
See e3-scramble.
Use to configure the framing format for a T3 or E3 line.
For a T3 line, you must specify one of the following:
T3 FRAME—c-bit or m23 (the default is c-bit)
T3 ATM—cbitadm, cbitplcp, m23adm, or M23plcp (the default is cbitplcp)
For an E3 line, you must specify one of the following:
E3 FRAME—g751 or g832 (the default is g751)
Choose a framing format that is compatible with the framing format of the network
device at the other end of the line.
Example
host1(config-controll)#framing m23
Use the no version to restore the default value.
See framing.
You can configure fractional T3 on T3 frame interfaces. E3 frame interfaces do not support
fractional E3.
Fractional T3 is a portion of a T3 transmission service and provides a set of lines with a
speed that is greater than T1 (1.544 Mbps), but less than T3 (44.736 Mbps).
