The complete NCC 2020 assembly consists of a front-panel module and a rear panel connector interface module, together occupying a single shelf-slot position accessible from the front and back of the AS2000 rack or shelf. The CIM is installed from the rear of the shelf into the backplane. The NCC 2020 front module is installed from the front. The CIM is always installed first and removed last. The NCC front module is installed last and removed first; it is equipped with ejector handles.
The NCC module front panel provides indicator LEDs and management ports. It also provides a Craft interface port and signal access jacks.
NOTE: The bantam type signal access jacks provide access to internal signals within the module. If the NCC 2020 is being used with any type of DIU (DSU) module, the signals on the bantam jacks will NOT reflect line signals and this jack field should not be used.
