Undoing a Command or Feature
If you want to undo a command you entered or disable a feature, enter the keyword no before most
commands; for example, no ip routing.
Saving Configuration Changes
Enter the copy running-config startup-config command to save your configuration changes to
nonvolatile random-access memory (NVRAM) so that they are not lost if there is a system reload or
power outage. For example:
Router# copy running-config startup-config

Step 7
Router(config-controller)# ds0-group 1 timeslots ?
<1-24> List of timeslots which comprise the
ds0-group
Displays the range for the timeslot
option. Specify a time slot range of
values from 1 to 24. You can specify time
slot ranges (for example, 1-24),
individual time slots separated by
commas (for example 1, 3, 5), or a
combination of the two (for example 1-3,
8, 17-24). The 16th time slot is not
specified in the command line, because it
is reserved for transmitting the channel
signaling.
Step 8
Router(config-controller)# ds0-group 1 timeslots
1-24 ?
Displays the two commands (service and
type) available for the time slots.
service
type
Specify the type of service
Specify the type of signaling

1-24 type ?
Lists supported signaling types.

dtmf DTMF tone signaling
mf MF tone signaling
service Specify the type of service
<cr>
Displays the types of channel-associated
signaling available for the e&m-fgb
type.
Step 11
Router(config-controller)# ds0-group 1 timeslots
1-24 type e&m-fgb dtmf ?
