NCC
3DB 23063 ADAA - Rev 004 July 2007
The NCC is central to the operation of the INU/INUe. It provides management
and control functions, local NMS access, and DC power input. Refer to Table F-1
for details.

Description
Supports primary control and management of the node.
Supports the operation of the backplane TDM bus (buses
A&B; specifically the timing (data rate) and control (frame
synchronization). When an NPC plug-in is installed in an
INU/INUe, timing processor functions are backed-up
(protected) by the NPC.
Supports up to six INU/ODU telemetry channels, one for each
possible RAC/ODU installation.
The telemetry channels connect directly between the RAC
plug-in and a microprocessor-supported serial controller.
They are not carried on the TDM bus.
The CompactFlash card plugs into the right side of the NCC,
or at the rear of the IDU (9500 MXC Terminal). It holds the
system configuration (CT config.), system software
(embedded software) and, for the 9500 MXC Node, the
licensed level. Each CompactFlash is assigned a unique serial
number, which is the license serial number.
Supports four RJ-45 10/100Base-T Ethernet ports for NMS
access, and router functionality for static and dynamic routing
options.
One RJ-45 port provides a serial asynchronous data port
(V.24) for dial-up CT access.
Supports monitoring of power supply voltages and other
analog signals.
• One channel of the ADC is dedicated to a temperature
sensor associated with FAN control.
• It includes an internal level reference accurate to within ±
1% over the INU/INUe operating temperature range.
Provides the various internal voltage rails.
