Requiring Internal Clocking on T1 Interfaces

This example shows you how to use a commit script to require T1 interfaces to be configured with internal clocking.

This commit script ensures that T1 interfaces are explicitly configured to use internal clocking. If the clocking statement is not included in the configuration, or if the clocking external statement is included, an error message is emitted and the configuration is not committed.
