Overview
Verilink NCC 2020 User Manual 1-3
Components
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.
NCC 2020 Front
Panel
The NCC 2020 front panel provides thumbwheel switches, LED
indicators and management and monitor ports. It is equipped with
dual ejector levers to facilitate installation and removal of the
module.
