ECLIPSE INSTALLATION MANUAL
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 Node management and DC-DC converter func-
tions. NCC is a mandatory card.
l It manages Node operation and event collection and management.
l It incorporates a router function for local and remote network management
interconnection.
l Node configuration and licensing data is held in flash-memory.
l Power supply: -48 Vdc (SELV -40.5 to -60 Vdc).
FAN (Fan card) provides forced-air cooling. FAN is a mandatory card.
NPC (Node Protection Card) provides 1+1 protection functions for the NCC power
supply and backplane management.
PCC (Power Conversion Card) supports operation from a +24 Vdc power supply.

RAC 60E
RAC 60E supports DPP (Data Packet Plane) operation, ACM (Adaptive Coding and
Modulation), and airlink recovered timing (ART) for high accuracy radio transport of
a SyncE clock.
There are four dynamically switched modulation rates; QPSK, 16 QAM, 64 QAM,
256 QAM. Coding options additionally apply on each of these modulations, one for
maximum throughput, one for maximum gain, to provide an effective total of eight
modulation states.
l Maximum throughput delivers maximum data throughput - at the expense of
some system gain.
l Maximum gain delivers best system gain - at the expense of some throughput.
l Up to four of the eight modulation states offered with ACM can be selected for
use.
l Modulation switching (state change) is errorless for priority traffic.
A DPP port enables direct routing of Ethernet traffic to a DAC GE3.
Individual ACM modulations can be set as fixed rates. These are complemented by
fixed-only rates for TDM capacities (DS1, DS3, OC3).
ANSI channel bandwidths range from 3.5 to 80 MHz.
Air-link capacities for Ethernet, or for Ethernet+TDM, extend to 366 Mbit/s.
TDM options extend to 127xDS1, 4xDS3, 2xOC3.
Payload encryption is a licensed option.
