Attention: The steps to uninstall the spring steel buckle are just contrary to install.
Step 7: Set up an application environment.
Connect the line from the NT port in central office with the TE port and the line from the TE port
in central office or an ISDN phone with the NT port to set up an application environment. If the
TE port in central office or the ISDN phone requires the NT port to provide feed, you should
turn on the PSW slide switch of the corresponding channel as well as the slide switch
corresponding to Port1 or Port2 on the module NT200.
Step 8: Connect the clock synchronization line.
Note: Skip this step if there is no need to get clock synchronization for multiple boards.

2. For a BRI16 full-length motherboard and a board of other model (such as a digital trunk
board), when they are connected with a clock synchronization line, powered on and
loaded automatically with the driver, please execute the following command to activate
the clock synchronization configuration.

Note: If the file /sys/module/bri16/parameters/clockconf does not exist, you may try to use
/sys/module/bri16/clockconf to replace /sys/module/bri16/parameters/clockconf on
