Eclipse Installation Manual
INUe
The INUe requires one NCC and one 2RU FAN. It has provision for up to ten option
cards and supports a maximum of five RFUs for five non-protected links, or two
protected/diversity links plus one non-protected link.

Plug-in Cards
Plug-in cards for the INU or INUe enable quick and easy customization on Eclipse
configurations. All cards are hot-pluggable.
• RACs support the radio modem function. In the transmit direction they take the
digital traffic from the backplane or data packet plane and convert it to an IF signal
for connection to an IRU600. The reverse occurs in the receive direction.
• One RAC with one 1+0 IRU 600 is used for a 1+0 link.
• Two RACs with one 1+1 IRU 600 are used for 1+1 or diversity links.
• RACs control TX switching and RX voting on protected / diversity links.
• XPIC (cross polarization interference cancellation) RACs support CCDP
(co-channel dual polarization) operation.
• DACs support the user interface. They take the user traffic and convert it into a
format compatible with the data backplane, where it cross-connects to a RAC or
RACs, or to other DACs.
• Different DACs support DS1, DS3, OC3, and Ethernet connections.
• Multiplexer DACs support transport of OC3 or DS3 with NxDS1 rates.
• Ethernet DACs support a L2 switch function. The GigE DAC GE supports
advanced ring/mesh, link aggregation and VLAN tagging options.
• Most DACs can be protected using a stacked (paired) configuration.
• DS1, DS3, and OC3 DACs support Ethernet-over-TDM options to enable Ethernet
transport over legacy TDM radio or leased-line links.
• AUX (Auxiliary card) supports async or sync service-channel connections, and
alarm I/O options for connection to external devices.
• NCC (Node Controller Card) provides the node management and DC voltage
conversion functions. The NCC is a mandatory card.
• It manages Eclipse operation and event collection and management.
