NEAX2000 IVS General Description
NDA-24293, Issue 2
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 NEAX2000 IVS
term
D series digital electronic multifunction terminals. The D
intelligent microprocessor controlled terminals, 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 NEAX2000 IVS
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, should a
minor fault occur, 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 NEAX2000 IVS
assignment to meet all forms of network integration service.
13. Future Capabilities - Because the NEAX2000 IVS
performance enhancements and new features can be easily incorporated by simple
changes in software. The NEAX2000 IVS
current software release and, when necessary, additional hardware. This means
that the system will not become obsolete.
