Engineering service channels

The equipment comprises:
--
in the classic IDU configuration: five engineering service channels (ESC N_1 to ESC N_5), except
in the 2 x 2 Mbit/s configuration (only three ESC).
--
in the Light IDU configuration: two engineering service channels (ESC N_1 and ESC N_3).
In the main classic IDU and in the Light IDU, the characteristics of these engineering service channels are
predefined.
The extension IDU (classic IDU version) can be used to customize ESC N_3, N_4 and N_5. This unit has a
SCU board installed with daughter boards to customize ESC N_3 and N_4.
The table below summarizes the ESC options available according to whether the configuration includes a main
IDU (classic, Light) or a classic main IDU with an extension IDU.
