Node Plug-in Cards
This section highlights current plug-in cards for an INU/INUe.
NCC
The NCC is a mandatory plug-in for an INU/INUe. It performs key node management
and control functions, and provides various dc rails from the -48 Vdc input. It also
incorporates a plug-in flash card, which holds Node configuration and license data.

FAN
The FAN is a mandatory plug-in. There are two variants, 2RU and 1RU. Each is fitted
with two long-life axial fans plus monitoring and control circuits.
• One 1RU FAN is fitted in an INU.
• One 2RU FAN or two 1RU FANs are fitted in the INUe. The 2RU FAN is standard.

RAC 30v3
RAC 30v3 interfaces to an ODU 300hp/ep/sp for channel bandwidths up to 28 MHz
(ETSI) or 30 MHz (ANSI) for capacities of:
•10 to 150 Mbps Ethernet
•5x to 75xE1
• 4x to 100xDS1
•1x, 3x, 4xDS3
• 1xSTM1/OC3
Where transport of E3 rates is required, the DAC 3xE3/DS3M is used in E13 mode to
multiplex the E3 data to NxE1 on the backplane bus.
