Aspire S Trunk Pcbs - NEC Aspire Manual

If PoE (power over ethernet) is to be used to eliminate the separate power adapters, a separate power
source is required. It is recommended that you use a power switch and/or power hub which is IEEE
802.3AF compliant. For example, the PowerDsine 6xxx series of products is unique in the fact that
in addition to offering IEEE 802.3AF support, it also provides for the NEC proprietary detection
and, therefore, the ILPA (In Line Power Adapter) is not required. For systems which require layer 2
switching capability and PoE, the NEC BlueFire 200/24 switch is recommended. This unit provides
layer 2 switch capability in addition to being able to supply ethernet power to 24 NEC IP terminals.
For this unit, power feeding is through the signal pair (1/2, 3/6) or spare pair (4/5, 7/8).

Aspire S Trunk PCBs

4 CO Loop Start Trunk Card (4COIU-S) —
P/N 0891046
The Analog Trunk (4COIU) PCB provides:
●
●
●
●
●
●
The CN5 and CN7 connectors each provide connection to 2 analog trunk
ports, which are polarity sensitive (tip to tip, ring to ring). The power
failure circuit, however, is not polarity sensitive. A maximum of 2
4COIUs per system is allowed.
2 DID/OPX (2DIOPU-S) Card — P/N 0891047
The 2DIOPU PCB supports the analog DID and single line telephone
interface functions (such as Off-Premise Extension). The function type
is assigned in programming for each port.
The DIOPU PCB provides:
●
●
●
●
The CN201 connector provides connection to 2 analog DID trunk ports,
which are polarity sensitive (tip to tip, ring to ring). The OPX circuits,
however, are not polarity sensitive. The DIOPU requires one universal
slot, with 4 maximum PCBs per system. The system will assign either trunk or extension ports to
the PCB based on the system programming (10-03-01). The PCB provides track resistance of 1500
ohms (PB loop) and 3000 ohms (DP loop) which includes the DC resistance of the terminal. This
PCB requires system software 2.21 or higher.
