To enable Scrambling, configure Scramble under the respective Serial Interface for the T3/E3 Controller.
Refer to
Table 57: DSU Modes and Vendor-supported Bandwidths, on page 995
for more information regarding
the modes.
The local interface configuration must match the remote interface configuration. For example, if you define
the data service unit (DSU) interoperability mode as
digital-link
on the local port, you must also do the same
on the remote port.
You must know what type of DSU is connected to the remote port to determine if it interoperates with a T3
or an E3 controller. The
dsu mode
command enables and improves interoperability with other DSUs.
To verify the DSU mode configured on the interface, use the
show controllers t3
command in EXEC mode.
