Usage Guidelines
The default DSU mode Cisco is equivalent to Digilink Mode with Scrambling Enabled. This mode was added
to enable scrambling along with Digilink mode on E3 Controllers.
Digilink Mode, by definition does not support scrambling for E3 Controllers though it supports the same for
T3 Controllers. For T3 controllers, there is no functional default DSU mode. The DSU Mode Cisco is not
applicable for T3 Controller.
For interoperability, it is recommended to always configure the DSU mode command under T3/E3 Controller
by matching the DSU type of the remote port.
