NEAX SYSTEM OVERVIEW

CHAPTER 1 NEAX SYSTEM OVERVIEW

The NEAX2400 Internet Protocol eXchange (IPX), the newest member of the NEAX family, fuses existing NEC
technologies with dynamic advancements in hardware and software to satisfy the most stringent system require-
ments.
NEC also introduces Internet Protocol (IP) medium into the NEAX2400 IPX. This capability allows the
NEAX2400 IPX to provide all of NEC’s networking services and D

term

Series digital telephone features when de-
ployed over an IP network.
NEC’s modular design, distributed processing, sensible migration, comprehensive network solutions and the abil-
ity to customize functionality to match specific business applications are just a few of the NEC benchmarks that
the NEAX2400 IPX builds upon.
The NEAX2400 IPX provides over 780 service features that enhance productivity, reduce operating costs, and im-
prove communications efficiently. Innovative modular hardware and software design allows the NEAX2400 IPX
to serve efficiently and grow incrementally over its entire size spectrum, ranging from 384 ports to over 24,576
ports.
The NEAX2400 Internet Protocol eXchange has the ability to expand from its minimum configuration to its max-
imum capacity with virtually no loss of existing hardware. This unique expansion capability allows the system to
grow in a cost-effective manner as the user’s requirements grow. This system is truly unique in today’s telecom-
munications industry.
By serving as the controller of an integrated information network, the NEAX2400 IPX is able to integrate and en-
hance all forms of advanced information processing and management services. The NEAX2400 IPX combines
voice and data, store and forward, packet switching and many other advanced features.
The system also delivers advanced applications such as CCIS, Fusion and IP Networking, IP Stations, Remote
Switching, Centralized Attendant Service, Direct Digital Interface, Integrated ACD, Voice Messaging Integration,
along with many other feature-rich capabilities via the Open Applications Interface (OAI). This reflects the NEON
(NEC’s Enterprise Open Network) Concept, and makes it possible for the NEAX2400 to provide both voice and
non-voice services.
Proprietary digital instruments (D

term

) may be provided to increase system flexibility and eliminate the need for
conventional multiple line stations with their associated control equipment and cable plant requirements.

NEON CONCEPT

CHAPTER 2 NEON CONCEPT

NEON, NEC’s Enterprise Open Network, represents the guiding principles for NEC’s product strategy. NEON
embodies NEC’s philosophy that drives development of complementary communication solutions for OPEN net-
works, delivering value-added capabilities and quality of service, while protecting investment; all without compro-
mising the user experience.
While we would like nothing better than to provide an end-to-end converged enterprise network solution, we real-
ize that a customer’s network almost always consists of a multi-vendor environment and will require an open so-
lution. But unlike many vendors who define “open” as standards compliance, delivering the lowest common
denominator in functionality, NEC’s NEON philosophy delivers value-added solutions within the context of an
open network. Therefore, NEC products can provide important new capabilities with minimal impact on the exist-
ing investment.
NEON-driven solutions perfectly position NEC customers to take advantage of emerging technologies such as
IP Telephony, where and when it makes best business sense for their enterprise. In fact, NEC predicted IP Teleph-
ony, the convergence of voice and data technology, as early as 1977. However, despite the hype fostered by some
in the industry, the IP Telephony journey has only just begun.
NEC believes that a new solution should never offer less than the enterprise’s existing system. Many vendors
offering IP Telephony do so with the assertion that a customer must abandon most of the traditional telephony fea-
tures. They offer a glimpse of new applications derived from the converged solution, but leave behind many im-
portant telephony capabilities that have evolved over the last 20 plus years.
What they are missing in this approach is a basic appreciation for these features as tools for building workgroup or
individual user solutions for call handling and coverage that in many cases are critical to operating the business.
Under the NEON philosophy, we are committed to full IP Telephony capability while preserving all of our current
features and the existing user experience.
What you buy today must stand the test of time as the IP Telephony journey continues. NEC’s commitment to tech-
nology migration has been clearly demonstrated for the last two decades. As the NEON philosophy dictates, we
have deliberately chosen to migrate all of our product platforms. When you invest in an NEC solution, you can
choose the NEC system platform that is most cost-effective and scaled appropriately for your needs. So whether
an enterprise is looking to migrate existing investment toward IP Telephony or is contemplating a new investment
in this technology, selecting a vendor with a proven commitment to cost-effective system migration is critical to
preserving investment.
Choice is a direct result of our application of the NEON principles. You can implement as much or as little IP Te-
lephony as you need, maintain or install TDM solutions where required, and be assured of a smooth path towards
an eventual, fully distributed converged IP Telephony solution. Simply put, NEC solutions are all about choices.

NEAX2400 IPX BENEFITS

CHAPTER 3 NEAX2400 IPX BENEFITS

The NEAX2400 IPX provides a unique set of advantages to users seeking an advanced information system that is
both flexible and dependable. Through the use of state-of-the-art computer controlled telecommunications tech-
nology, NEC is able to provide the following advantages:



Scalability

NEC IP Solutions defy obsolescence at all levels of technology deployment, enabling you to invest at your own
pace without risking anything tomorrow. If you are a current NEC customer, you can deploy IP capability at the
terminal, line card or trunk card level with simple upgrades, depending on which NEAX communications system
you have. If you are a new customer, we offer NEAX communications systems that are fully IP-ready. Which
means, you get all the benefits of IP telephony, plus the proven reliability of today’s voice platform technology.



Fully Featured System

NEAX2400 IPX station users have access to more than 780 service features that enhance user productivity, reduce
operating costs, and improve communication efficiency. In addition, the control, network and interface of the
NEAX2400 IPX can accommodate features, services and subsystems as required by specific applications.



Network Integration

The NEAX2400 IPX offers business, industry, hospitals and hotel/motels the ability to access an extensive array
of information processing and management services by serving as the central controller of an integrated informa-
tion network. The NEAX2400 IPX reflects the philosophy of NEON (NEC’s Enterprise Open Network) concept,
which can provide many voice and non-voice services.



Flexible Line Size

Innovative modular hardware and software design allows the NEAX2400 IPX to efficiently serve from 384 ports
to 6,144 ports, and also FCCS enables port expansion to 24,576 ports. Modularity gives the system the ability to
be expanded from its minimum configuration to its maximum capacity as the need arises. This unique expansion
capability allows the system to grow in a cost-effective manner as the user requirements expand. Your initial sys-
tem investment is protected through this growth capability.



Energy Saving and Space Savings

Through employment of state-of-the-art technology in the system circuitry design, NEC has been able to reduce
power consumption. As a result, the current consumption of the system has been reduced to less than that of any
conventional electronic PBX system. This energy saving oriented system design allows for the use of much smaller
capacity main power equipment and air conditioning equipment. In parallel with the energy savings, the space re-
quirement for the system has been reduced to one third when compared with that of a conventional electronic PBX
system.

CHAPTER 3 ND-91674(E)

NEAX2400 IPX BENEFITS



Building Block Configuration

In a conventional switching system, various kinds of equipment are mounted in a cabinet group and are connected
to each other by use of connecting cables. However, the NEAX2400 IPX utilizes a building block modular design.
When installing the system, the required blocks are placed on top of each other in a building block formation.



Flexible Interface Port

The NEAX2400 IPX employs Universal Port architecture that has the flexibility to accommodate station terminal
equipment, trunks and adjunct processors. This universality allows the NEAX2400 IPX to maximize slot space uti-
lization and lower expansion costs.



Redundancy

The basic design philosophy of the NEAX2400 IPX is to provide redundant capacity for all critical circuitry such
as processors, control circuitry, memory, switching network and power. By providing this redundancy, NEC is able
to offer a highly reliable system with an extremely high grade of maintainability and sophisticated fault diagnostics.
The NEAX2400 IPX has all the inherent reliability required to control network integration services.



High Reliability

The NEAX2400 IPX is designed and manufactured to provide the highest level of system reliability. The
NEAX2400 IPX is designed with such features as: remote maintenance, distributed call processing, error-correct-
ing memory, equipment redundancy, battery backup, self testing 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.



Intelligent Attendant Console

The NEAX2400 IPX attendant console is a compact, desktop unit that provides continuous information relative to
the status of calls in progress.



Intelligent Digital Multifunction Terminal

In addition to supporting conventional station equipment, the NEAX2400 IPX can be equipped with the D

term

se-
ries of digital electronic multifunction terminals. The D

term

instruments are intelligent microprocessor controlled
terminals, which enhance the feature capabilities offered by the system while providing the service of conventional
telephones over 1-pair wiring. The D

term

instrument may be equipped with an interface adapter to allow simulta-
neous voice and data switching, without compromising the voice communication system.

ND-91674(E) CHAPTER 3

NEAX2400 IPX BENEFITS



Ease of Installation

Because the NEAX2400 IPX uses pre-assembled modules and plug-in type circuits packs, it is easy to install. In-
ternal and external wiring connections 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 installation obstacles are
held to a minimum.



Ease of Maintenance

Since the system is constructed with the highest quality components, reliability is insured and operation is trouble
free. However, should a minor fault occur, the self-diagnostic programs will detect the fault, and automatically
make the needed correction(s). If the problem is beyond the internal correction capabilities of the system, the self-
diagnostic programs will send notification as to the nature of the fault and the involved unit to the Maintenance
Administration Terminal. The alarm display panel provides additional notification of any errors detected. The
faulty plug-in unit can then be quickly replaced with little or no interruption of service.



Flexible Numbering Plan

The NEAX2400 IPX provides a flexible numbering assignment to meet all forms of network integration service.



Future Capabilities

Because the NEAX2400 IPX uses a stored program control, performance enhancements and new features can be
easily incorporated by simple changes in software. This means that the system will not become obsolete, protecting
the initial investment.



Cost Controls

With Telecommunications costs growing, it is becoming increasingly important to control them. The NEAX2400
IPX makes it possible for you to get a firm grasp on telecommunications costs. Through the use of such features
as Least Cost Routing (LCR), Class of Service (COS) and Station Message Detail Recording (SMDR), cost reduc-
tion and controls are possible.

NEAX ENTERPRISE SOLUTION

CHAPTER 4 NEAX ENTERPRISE SOLUTION

4.1 IP Telephony Solution

Recently network data traffic is growing rapidly. Internet and Intranet communications are fast becoming critical
parts of everyday work and life. The solution everyone talks about is multiservice networking – running data,
voice, video and other information over a common IP network. Multiservice networking is the future of telecom-
munications.
NEC IP Telephony solutions are part of the NEON strategy: NEC’s Enterprise Open Network. NEON embodies
NEC’s philosophy that drives development of complementary communication solutions for OPEN networks, de-
livering value added capabilities and quality of service, while protecting investment; all without compromising the
user experience.
NEAX2400 IPX supports connectivity and access to internet/intranet with related products to provide to IP. NEC
IP solution allows users the peace of mind in knowing that today’s investment can be upgraded without compro-
mising the user experience. Through NEC’s FCCS strategy, a business or enterprise may choose the networking
environment most advantageous for its business thus gaining a more reliable, less complex and more manageable
network infrastructure via converged voice/data network. NEC’s IP Telephony solution initiative represents a di-
rect response to the growing demand for network convergence solutions that fully satisfy customer expectations.

NEAX ENTERPRISE SOLUTION
4.1.1 NEAX IP WAN Solution

NEAX2400 IPX supports IP WAN network easily and economically. NEAX2400 IPX converts Voice to IP packet
to communication over the Intranet.
Network utilization is more efficient and therefore lower cost of operations.
NEAX2400 IPX provides the following major services for customers.



FCCS/CCIS over IP

In an environment in which the integration of voice and data over IP has becoming commonplace, the capability
to offer CCIS/FCCS over IP brings a welcome reduction in TCO (Total Cost of Ownership). A major service fea-
tures provided by CCIS enables multi-site system to work together as if they were a single system for superior fea-
ture transparency and centralize facilities within the network such as attendant, billing system, and voice messaging
system.
By using FCCS over IP, multiple NEAX2400 IPX system can be operated various services such as number porta-
bility, centralized maintenance and wireless roaming etc.



Voice over IP based on H.323 Standard

NEAX2400 IPX offers support in the form of H. 323 standard protocol compatible gateway, facilitating IP con-
nectivity with network equipment of other vendors .
In order to optimize the bandwidth of the IP network, the IP Trunk Card (IPTC) supports voice compression such
as G.711(64Kbps), G.729a(8Kbps), G.723.1(5.3K/6.3K) and FAX (T.30/T.38 ).
A H.323 Gatekeeper is required to facilitate call establishment and termination and provide function such as ter-
minal and gateway registration, address translation, bandwidth control, etc.

4.1.2 NEAX IP LAN Solution

With traditional PBX system, any moves and changes increase operational costs.
New cables have to be laid and data setting had to be changed by the engineer.
But, with NEAX2400 IPX system, just simple data change can achieve migration to the IP LAN office environ-
ment.
The following NEAX IP LAN solution is more suitable for enterprises with frequent organization changes, and
also it can reduce TCO(Total Cost of Ownership) such as investments in both new telephones and LAN cabling
and moving & laying of telephone cables.

4.2 Network Solution

The NEAX2400 IPX is a business passport to the most sophisticated networking capabilities offered today.
The major networking capabilities of the NEAX2400 IPX are shown below.
• Private Networking



Fusion Call Control Signaling (FCCS), for being dispersed with in the network to operate as if each of
them are part of a single integrated PBX system.



Common Channel Interoffice Signaling (CCIS), for multilocation organizations requiring the several
NEAX2400 IPX, operate as a single system.



Distributed Access Unit (DAU), for remote groups of D

term

75 Series station users to provide full feature
transparency.
• Public Connectivity



Integrated Services Digital Network (ISDN)



Q-SIG (Circuit Switched Basic Call-ETSI Version)



Digital Multi-Frequency Compelled Signaling R2 (MFC-R2)

4.2.1 Fusion Call Control Signaling (FCCS)

In the tradition of NEC’s CCIS, but unlike the earlier application, FCCS enables individual NEAX2400 IPX nodes
dispersed within network to operate as if each of them are part of a single integrated PBX system. This capability
gives NEC a significant edge over other network designs in providing corporate or enterprise systems. FCCS uti-
lizes a database storage, share and access routine that allows the network to learn what database elements are in
separate nodes within a network. Fusion Call Control Signaling (FCCS) allows access in real time from any node
in the network to the database of any other node in the network. FCCS gives the network the ability to perform
point-to-point database downloads throughout the network, so that nodes in the network may “learn” the attributes
and elements of the entire network configuration.



Distributed Versus Monolithic

Distributed network architecture will always be compared to remote distribution of elements of monolithic system
architecture. These network designs take pieces of a single system and extend those pieces across campus or miles
away from the common control of the system. As this is not a very effective network design when reliability is
concerned, it does have the advantage of a single database for administrative purposes.
The FCCS approach to networking, combined with a single point of administration, creates a network architecture
that operates as one unit while being virtually immune to catastrophic failure.

The Ultimate in Networking by Design

FCCS provides “enhanced” feature transparency between nodes of a network and administration from a single
point of entry for a network common database. This is accomplished by CPU to CPU communications-over IP-
between nodes within an FCCS network. In earlier applications with CCIS, one node in a network, which needed
information from another node to process a call would wait for a response from the distant node before further
processing is performed. Although this routine has been very effective, a node in the new FCCS network shares on
a common database of the network. Thus improving the call processing performance and efficiency of the proces-
sor as well as the network.

Logical and Physical Association for Number Portability

One other contribution FCCS provides for the network administrator and an ever-mobile corporate society is the
ability to have full numbering plan mobility throughout the network. By “learning” what database is contained in
other nodes of the network, FCCS offers the intelligence and flexibility to allow station numbers to move across
the nodes in the network. This is accomplished by the use of the association of the software number with the phys-
ical location.
In the past, PBX architectures depended on the physical location or port to be directly linked to the hardware port.
This requirement allowed the system to correlate the class of service, toll restriction and administrative information
such as name, number, Call Accounting and Voice Mail personal greeting to be accurately managed. FCCS and
the NEAX2400 IPX introduces the separation of the software address which is now associated with a person or
extension number from the physical hardware. This is only possible when a node of a network is intelligent enough
to know the attributes of the other nodes. This is accomplished through a common network database.
With FCCS, an employee that is taking a tour of all nodes within the network could be scheduled so that when they
arrive at each location, their software association and telephone attributes may be waiting for them for non stop
productivity. This software association will include their service class, toll restriction, direct in dial operation,
voice mail and call accounting to be accurately controlled and full feature transparency within all nodes within the
network.

4.2.1.1 Fusion Call Control Nodes
A FCCS Network consists of the following types of nodes:
• FCCS Control Node (NCN)
Network Control Node, which must be assigned on a FCCS Network, manages other nodes on the network.
This node has the Centralized-MAT to collect fault information of other nodes on the network. Note that
multiple nodes cannot be assigned as a Network Control Node.
• Local Node (LN)
All nodes except Network Control Node are called Local Node. Fault information generated at a Local
Node is sent to the Network Control Node via a FCCS Link, allowing the Network Control Node to collect
the fault information. A FCCS Network can have a maximum of 16 nodes on the network.
• Center Node (for Centralized Billing via FCCS) (CN)
This node collects the billing information of other nodes as well as the self-node. For this reason, the node is
called as a Center Node for Centralized Billing via FCCS. Multiple Center Nodes can be assigned on the
network by specifying the polling destinations. At the Center Node, the user can select “polling destina-
tions” by setting 1 to the FPC of the corresponding nodes.
* Assign the self-Fusion Point Code (self-FPC) at each node. FPC ranges from 1 to 253.
 FCCS Capacities
Up to 253 nodes or systems may be connected within a single FCCS network for a maximum of 24,576 ports. Dis-
tance between nodes is only limited by the transport or the carrier’s ability to guarantee the quality of the network,
to meet or exceed the standards that are being used.
4.2.1.2 Data Memory Structure within Nodes
Each Local Node is responsible for maintaining its “Data Memory” and “Local Data Memory” and the “Network
Control Node” maintains the “Network Data Memory” for the entire network. When changes are made to the NDM
from the NCN, they are automatically copied to the NDM of each node within the network. In this way, the NDM
of the Network Control Node functions as the master memory for the entire network.
It is important to note that the “master memory (NDM)” refers to that data that is related to the network only, i.e.
Telephone Number of Stations and Routes, Fusion Point Codes, Least Cost Routing information, Access Codes,
etc. NDM does not include every detail of a local nodes data programming.
The Data Memory and Local Data Memory of each node are NOT controlled by the NCN but reside in each specific
node in the network to which it relates.

4.2.1.3 FCCS and CCIS Compatibility
FCCS and CCIS are fully compatible. When a network consists of mixed connections (NEAX2400 IPX connected
to earlier generation systems in the network) that connection will support the highest intelligence, feature transpar-
ency, and administrative capabilities of the earlier generation system.
Where the nodes of the network support FCCS (multiple NEAX2400 IPX systems communicating with one anoth-
er), the network operation between these systems will support all the capabilities of FCCS. The entire network may
achieve full FCCS operation with cost-effective upgrades to the previous generation systems.

 Conventional Private or Leased Line Network
FCCS and CCIS may be deployed over private or public facilities. There is no distance limitation between nodes
in a network as long as the network provider provides these services in accordance with accepted industry stand-
ards. In either public or private networks the connection between nodes may be any of the above listed transport
options.
FCCS also provides a high-speed information flow using the one channel of a 1.544 or 2.048 Mbps digital link
span, like CCIS “D” channel. But FCCS uses digital link only, therefore it has capacity of 64 Kbps per one digital
Trunk Interface (DTI) card between NEAX2400 IPXs.
Figure 4-12 NEAX2400 IPX FCCS Digital Signaling
4.2.2 Common Channel Interoffice Signaling (CCIS)
NEC’s CCIS enables a digital or analog Tie Line network of NEAX2400 IPX to function as a single Integrated
Communications System. This capability is attributable to the implementation of the ITU-T Signaling System No.7
Recommendations.
The CCIS system employs an efficient communications protocol called “Out of Band Signaling.” The CCIS “D”
channel provides a high-speed information flow using the one channel of a 1.544 or 2.048Mbps digital link span
or modem connections if analog Tie Lines are used between NEAX2400 IPXs.
CCIS is a “Message Oriented Signaling” protocol, incorporating Message Signal Units (MSU) for Call Set Up,
Feature Transparency, Diagnostics Maintenance and Centralized Applications such as SMDR, Fault/Management,
and Voice Mail. The Common Channel, denoted as the “D” (Data) channel, allows the transmission of these mes-
sage signals. Speech Lines used for voice or data communications are denoted as the “B” (Bearer) channels.

NEC has taken CCIS No.7 specifications and developed most of the voice and data features to be transparent over
the NEAX2400 IPX CCIS network. NEC has met the demanding requirements of sophisticated business on a net-
work level. This highly intelligent networking technique with feature functionality provides NEC users with ad-
vanced applications.
The architecture used for CCIS is same as ISDN. Both utilize 23B+D or 30B+D Primary Rate Interface. Both Net-
working types conform to and comply with the Open Systems Interconnection (OSI) 7 layer Model.
Figure 4-13 NEAX2400 IPX CCIS Digital Signaling
The following sections outline this feature-rich communications networking and explain the advantages of CCIS
over traditional private network.
 Calling Number/Name Display
If a station uses a D
term
75 Series terminal with display, this function enables a station which has been directly
dialled from another On-Net station to receive a visual number and/or name identification. This ID is sent to both
parties.
For example, when a station in a main office calls a station in a satellite office, CCIS enables the calling number
ID (NEAX2400 IPX office number plus the four digit station number) to appear in the display of both terminals.

 Numbering Plans
With CCIS, there are many possibilities for a network numbering plan. A small or large network can take full ad-
vantage of various numbering schemes. For example:
❏ 4-or 5-digit number without an NEAX2400 IPX Node ID
❏ 2-or 3-digit node ID plus free numbering for stations.
The second alternative allows station numbering plans to be repeated at two or more NEAX2400 IPX offices. The
location of each station is recognized by the two or three digit node ID.
 Least Cost Routing (LCR)
When using network Least Cost Routing (LCR), calling to a local facility of another NEAX2400 IPX node is ef-
ficient. For example, when a station user located in NEAX2400 IPX node-A (123 area code) dials a user in node-
B (456 area code).
To process the call, the CCIS “D” channel and network Least Cost Routing patterns attempt to establish a path via
network Inter Machine Trunks (IMT) without seizing any network facilities. The call is set up only if there is a free
and clear path to a local trunking facility directly connected to the NEAX2400 IPX node.
This method of networking saves costs, since the call is being routed on the customer’s private network and no
trunk facilities are seized until all connecting pathways are verified for idle status. The result is that long distance
carrier costs are reduced and fewer inter-exchange trunks are required due to the efficiency of CCIS.
 Centralized Station Message Detail Recording
Call records are an important part of revenue for telecommunication management. Through NEC’s advanced tech-
nology, a NEAX2400 IPX CCIS network simplifies this important task by allowing all billing information to be
centralized at a single location. Centralized billing in a CCIS network enables a single call record to be generated
even if a call requires a tandem connection through multiple nodes to access an Off-Net trunk facility.
In the earlier example, a station user’s call in a main office is routed via a tandem connection to a destination in a
satellite office to connect to a local facility. Using NEC’s Centralized Billing feature, only one call record would
be generated detailing that the station in the main office connected to the satellite NEAX2400 IPX node. Informa-
tion provided in that single call record would identify the originating station number and the facility used at the
destination NEAX2400 IPX. This call record would be produced on completion of the call in the destination
NEAX2400 IPX. The completed single call record would be transferred via the signaling link (D-Channel) to the
main billing center connected to the main office. Unlike traditional Tie Line networks, the need for additional fa-
cilities dedicated for SMDR is eliminated. The main billing center would have a mini/host computer to process the
Call Record.
 Centralized Management
The centralized management facility generates real time system messages to provide to the telecom manager de-
tailed information on items such as fault messages. For example, a fault message pinpoints the actual port or circuit
card which may have a problem. This allows a problem occurring at a node to be remotely and automatically di-
agnosed at the centralized maintenance facility.
The central node, upon receipt of this information, immediately outputs user friendly messages to a printer con-
nected to the MAT. Each node’s individual system messages can be identified, since each system node has an as-
signed name allowing messages from multiple sites to be separated. Included in the information transferred from
the faulty system is the hardware alarm fault and a visual indication can be seen on the display panel at the central
maintenance facility.
CHAPTER 4 ND-91674(E)
Page 24
NEAX ENTERPRISE SOLUTION
Besides messages and alarms being sent via CCIS to the Central Management Facility, the remote system where
the fault occurred will buffer and output the same information locally on its own printer.

4.3 Wireless Solution
A mobile work force no longer has to be dependent on special technology.
With personal telephone and Wireless Communication System, employees can travel throughout a multistored
building or across a large industrial complex and continue to stay in constant touch with customers and colleagues.
NEAX2400 IPX has built-in wireless system for providing wireless communication, it can support up to 4,000 us-
ers in the Multi-IMG.
4.3.1 Versatile Communication Tool for a variety of industries
(1) Business Offices
Even when an employee in the company cannot be reached at their desk, the wireless communication serv-
ice can put them in touch immediately.
A call from a customer can be connected directly to the called employee without holding the call or asking
the customer to call back. This means improved customer satisfaction.
Even when a company has offices in several different buildings, just install the connection unit, then all you
have to do is carry the handy phone set to place or receive calls anywhere. Since the wireless communica-
tion service does not require reinstallation of equipment or re-registration of extension numbers whenever
you change the office layout, it can effectively reduce costs.
(2) Medical Centers (or Hospitals)
By assigning a personal handy phone to each doctor and nurse, they can be reached anywhere in the hospital
for faster response to emergencies.
Better service can be offered to in-patients as well as patients with walking disabilities by lending them
handy phone sets.
Speedier communications is an extra touch that will make the patients reassured that they are in good hands.
(3) Plants
The wireless communication service allows bi-directional communications in large working areas such as
plants, warehouses, and factories.
Instructions and messages from the office or reports from the plant can be conveyed in real-time to help
improve productivity.
The wireless service also makes it possible to verify the process while moving over a line or to check the
inventory in the warehouse with someone in the office over the telephone.
Use the optional headset for hands-free communications without work interruptions for better safety and
work efficiency.
ND-91674(E) CHAPTER 4

(4) Department Stores and Hotels
On the sales floor, the wireless communication service allows a clerk to check inventory for a customer or
promptly call the manager. When holding an even or exhibition, or when changing the sales floor layout, the
wireless service requires no cable laying or transfer, so telephone installation and removal are simple.
At hotels and resorts, the wireless communication service can be used between the front desk and the rest of
the complex and for communications and instructions between staff members of an event in the complex.
Assign each security guard a handy phone set, and you can realize more systematic reporting and higher
mobility, as well as higher security in the event of an emergency.

4.4 Contact Center Solution
Contact center application is the important key to successful business communications.
With Contact Center, telemarketers are able to take advantage of any new marketing strategies involving consumer
telephone sales. ACD (Automatic Call Distribution) can do this by decreasing the time a caller will wait for the
next available agent. It is not only important that a call be held, but that it not wait longer than necessary. The
ACD provides queuing and levels of priority to ensure calls are handled in the order of arrival and importance. Call
distribution to agents must provide for even allocation. ACD does this by providing a queue for agents and callers.
These basic ideas and functions, when combined with an effective Management Information System, are the tools
to maximize profitability and efficiency. Processor for ACD is getting built-in processor of NEAX2400 IPX.
The NEAX2400 IPX Contact Center system is designed to be cost effective and still provide maximum flexibility
to custom fit the end user’s requirements. The NEAX2400 IPX Contact Center system can grow with a business
while accommodating software enhancements as they become available.
4.4.1 Automatic Call Distribution (ACD) Operation
There are many attributes that a true ACD must possess to provide cost effective handling of customer traffic. Two
basic features that distinguish an ACD are its ability to queue callers when agents are not available and queue
agents when callers are not available. This allows a smooth and even distribution of work load and incoming traffic
flow.
When all agents are busy and a call arrives, the ACD can control the length of time the caller will hear ringing
before the first announcement. The first announcement can be as long as two minutes or as short as two seconds
and can be followed by Music-on-Hold and/or a second announcement. During this time, a call may become eli-
gible to be handled at an alternate answering point.
Eligibility for overflow is possible as early as four seconds after the call has been detected. When the call becomes
eligible for overflow and the answering point is busy, the call will queue in two places, the original queue and the
overflow queue.
While calls are queuing, the agents can see the level of calls waiting by glancing at the call waiting lamp at the
agent’s position. The call waiting lamp has three states:
• Dark: there are no calls in queue
• Illuminated: calls are in queue
• Flashing: a preprogrammed threshold has been exceeded
As calls increase and decrease in the queue, the lamp status will change to inform the agents of the level of traffic
at that moment.
When an agent becomes available at either answering point, the call is immediately routed to that agent. If only a
limited number of calls are to be allowed to queue, the queue length can be adjusted. This feature provides an
additional alternative for call handling based on traffic loading.
ND-91674(E) CHAPTER 4

NEAX ENTERPRISE SOLUTION
A predetermined state can be established so that when an agent logs on, either the system extends calls automati-
cally or the agent must notify the system manually of his/her availability to take calls. An added security feature
can be used to prevent the agent from logging on to a split to which they are not a member. This is done by imple-
menting ID log-on codes.
During the course of any ACD call, agents may enter information about the type of call they are engaged in via the
stroke count feature. When the agent determines that they will require time after the current call before they can
take the next, they have the ability to stop new calls with the after call work key or the auxiliary work key.
In order to allow ACD agents to work more efficiently, automatic answer and automatic release may be utilized.
These features make it unnecessary for the agent to push any buttons in order to take or release calls. Besides these
capabilities, the agent can see the type of calls being offered before they answer. If, during a call, assistance from
a supervisor is required, a single button can be used to request a consultation.
The agent may determine, during a call, that the caller may best be helped by another split or department. In this
case, the agent may transfer the call to another split or NEAX2400 IPX station. If the call warrants a more serious
status, then the emergency key may be used to get help and simultaneously activate an emergency recorder.
If necessary, the supervisor, besides having all the same capabilities as an agent, has the ability to monitor and
record individual agent conversations. This feature, called supervisor monitoring, permits a supervisor to enter an
established call between an agent and a caller.

term
Series i for ACD Agent has been specifically designed for ACD operation and features, strategically
located buttons. The intelligent design provides the increased efficiency needed in a fast paced environment.
Headset and/or handset jacks are incorporated into the D
term
Series i for ACD Agent to accept either standard mod-
ular jacks.
The D
term
Series i for ACD Agent also features a three-line by a 24-character LCD display that can identify the
type of call by name or LDN (Listed Directory Number). This electronic digital terminal is designed for the ACD
environment, from its physical shape, which allows for comfortable placement of the operator’s hand, to the size
and placement of the most frequently used keys.

4.4.3 Management Information System (MIS) Operation
In order to manage system traffic loading and system configuration information, a comprehensive Management
Information System (MIS) is available. This system allows the status of the ACD to be monitored in real time.
The real time status of each split queue can be seen so that corrective action may be taken if needed. A split su-
pervisor may use the MIS to make changes to the system configuration, generate automatic statistical printouts,
create current system and configuration reports, and assign name changes and ID codes.
The MIS gives the split supervisor the ability to control the log-on state of the ACD agents, the time at which the
split will automatically change from day to night and night to day service, the type of night service, overflow
thresholds, and the assignment of trunks and agents. Reports from the MIS are available for the following catego-
ries:
• Per Trunk
• Per Trunk Group
• Per Split
• Per Queue
• Per Agent Position
• Per Agent
• Per Agent Group
• Call Delay Profile
• Stroke Count
NEC pays attention to the details. An important feature in the presentation of large amounts of numerical data is
to be able to suppress lines of zeros (i.e., non-data). The MIS system can do this any time it encounters more than
three hours of adjacent non-data. The zero suppression feature is useful if reports spanning hours of no activity are
called. It saves printer use and paper while eliminating the need to review non-information.
