installing the system, the required blocks are placed on top of each other in a building block
formation and interconnected by round bus cables.
(6) Flexible Interface Ports - The NEAX 2000 IPS employs a Universal Port architecture that has
the flexibility to accommodate station terminal equipment, trunks and adjunct processors. This
universality allows the NEAX 2000 IPS to optimize use of slot space and lower expansion costs.
(7) High Reliability - The NEAX 2000 IPS is designed and manufactured to provide the highest
level of system reliability. The NEAX 2000 IPS is designed with such features as: remote
maintenance, distributed call processing, error-correcting memory, battery backup, and
automatic system alarm indications to insure unsurpassed reliability. Only the finest
components have been used. In addition, through the employment of LSI and custom LSI and
VLSI technology, the number of component parts has been greatly reduced, thus lessening
possible failures and insuring continuous operation.
(8) Intelligent Attendant Console - The NEAX 2000 IPS attendant console, SN716 Desk
Console, is a compact, desktop unit equipped with non-locking keys, Light Emitting Diodes, and
a 4 x 40 character Liquid Crystal Display. The LED's provide continuous information relative to
the status of calls in progress. The display provides station and trunk identification, class of
service and the number of calls waiting. The LCD changes with different call states and instructs
the user which Multifunction keys are available for each state. Keys such as Busy Verify, DND
Override, etc. only appear when needed. The Multi-function Keys reduce the number of different
buttons and greatly simply operation.
(9) Intelligent Digital Multifunction Terminal - In addition to supporting conventional station
equipment, the NEAX 2000 IPS can be equipped with the D
multifunction terminals. The D
which enhance the feature capabilities offered by the system and provide the service of
conventional key telephones over 1-pair wiring. The D
interface adapter to allow simultaneous voice and data switching, without compromising the
voice communication system.
(10) Ease of Installation - Because the NEAX 2000 IPS uses pre-assembled modules and plug-
in type circuits packs, it is easy to install. Wiring connections, both internal and external, are
made through simple-to-use standard plug-ended cables. In addition, with each unit and system
having been fully factory tested prior to shipment, potential obstacles to easy installation have
been held to a minimum.
(11) Ease of Maintenance - Because the system is constructed with first quality components,
reliability is high and operation is trouble free. However, if a minor fault occurs, the self-
diagnostic programs will detect the fault, and automatically make the needed corrections. If the
problem is beyond the internal correction capabilities of the system, the self-diagnostic
programs will automatically print the nature of the fault and the involved unit is identified on the
man-machine interface equipment. The faulty plug-in unit can then be quickly replaced with little
or no interruption of service.
(12) Flexible Numbering Plan - The NEAX 2000 IPS provides flexible numbering assignment to
meet all forms of network integration service.
(13) Future Capabilities - Because the NEAX 2000 IPS uses a stored program control,
performance enhancements and new features can be easily incorporated by simple changes in
software. The NEAX 2000 IPS can be upgraded by using the most current software release and,
when necessary, additional hardware. This means that the system will not become obsolete.
