Aspire 8 Slot KSU w/o PS — P/N 0890000
The KSU is the system's control center. It houses the Power Supply, has
nine PCB slots and provides for connection to trunks and extensions. The
first slot in the KSU is dedicated to the NTCPU. The next slot is a univer-
sal slot which should be reserved for a Digital Station Card. The remain-
ing seven slots are also universal. They can be used for any combination
of Common, Trunk or Station PCBs. The KSU can be floor, wall or rack
mounted.
Central Processing Unit (NTCPU) PCB — P/Ns 0891002 & 0891038
The NTCPU controls all the functions and operations of the Aspire system
using the system software loaded into the NTCPU memory. One 32-bit
NTCPU PCB must be installed in the CPU slot in the Main Cabinet. There
are two versions of NTCPUs. The first version, P/N 0891002, is a 64-port
basic CPU. The second version, P/N 0891038, is a feature-enhanced, 256
extension port CPU.
To upgrade from the 64-port NTCPU, a Feature Upgrade chip (P/N
0891039) is available. The NTCPU provides a connector (CN14) for the
upgrade PAL EPROM chip. Make sure when installing this upgrade chip on
the NTCPU that you wear a grounded wrist strap.
Product Description
The system allows for a maximum of 32 110-button DSS Consoles. One extension can have a
maximum of 32 110-button DSS Consoles. As the 24-button DLS Console is connected to the
bottom of the phone, an extension can only have one 24-button DLS Console installed, but
each extension in the system can have a 24-button Console (256 max.). An extension can have
both a 24-button DLS Console and 32 110-button DSS consoles installed/assigned.
By default, the 24-Button DLS Console has no keys defined. These keys can be programmed
as line keys, extension DSS keys, or programmable function keys using Program 15-07. To
program the keys, use the extension number to which the DLS is installed and, regardless of
the type of keyset connected, start programming the DLS keys at key number 25. Service
codes 851 and 852 can also be used to program these keys if allowed by an extension's Class of
Service.
By default, the 110-Button DSS Console has extension DSS keys defined. These keys can be
programmed as line keys, extension DSS keys, or programmable function keys using Program
30-03-01. Service codes 851 and 852 can also be used to program these keys if allowed by an
extension's Class of Service.
You should plug a Digital Station Card into the first universal slot.
