2. NOTICE WHEN USED
2.1 Consideration of PBX, Power-related Equipment and Peripheral Equipment
This item describes the consideration before using PBX, the power-related equipment, and the peripheral equipment (such as console, MDF, DAU, telephone, PC, printer, etc).
Preserve the following:
DANGER
When the system gives off smoke or burning smell, it might cause a fire, an electric
shock, or a failure if the system keeps operating. Turn off the power and confirm the
smoke disappears, and then contact supplier.
PWR
If equipment (such as PBX, Main Power, cabinet, and peripheral equipment) fall down
and be broken, turn off the power, and then contact the supplier.
If the inside of PBX or Main Power is wet by liquid such as water, turn off the power.
It might cause a fire, an electric shock, or a failure if the system keeps operating.
Do not touch the internal parts of Main Power for the purpose of disassembly and remodeling. It might cause a fire, an electric shock, or a failure.
(NEC does not take any responsibilities if the system or the equipment is disassembled
or remodeled.)

DANGER
Do not damage, remake, forcefully bend, forcefully extract, nor forcefully twist an electric code and a wiring to/from PBX, Main Power and peripheral equipment. It might
cause a fire, an electric shock, or a failure. If the wiring is damaged, ask the supplier to
fix it.
dust
PWR
Insert the electric plug into the outlet properly. Confirm no dust is on the blade of plug;
it might cause a fire.
Do not use other than the power designated when installed.
PWR
Do not try to fix or move Main Power by yourselves without the supplier or service technician’s help. Please ask them when the repair or the movement is necessary.
Do not put any metal or combustible object into a vent of PBX, Main Power, and the
peripheral equipment. If the object is in those equipment, turn off the power and ask the
supplier. It might cause a fire, an electric shock, or a failure if the system keeps operating.
Be careful of using the display part which the peripheral equipment has. In the case of
liquid crystal, the liquid is leaked and causes harm to human body and systems.
Before connecting customer-provided equipment (such as the other company products)
with NEC products such as PBX and peripheral equipment, ask the supplier and make
?
sure your equipment is compatible with NEC product. If it is not confirmed, do not connect them. It might cause a fire or an electric shock.

WARNING
Fix the equipment. Do not put any object on PBX and Main Power; it might be dangerous if the object should fall down.
When plugging off a plug, be sure to grip the plug and extract it. If you grip the code
and extract it, it might cause a fire and an electric shock.
If a fault is considered as the lightening cause, ask the supplier.
Other than fulfilling the appropriate humidity and temperature, it is necessary to consider the maintenance operation and the all-time ventilation in non-loading operation during day-off and night. For example, when the height above floor is 1 m (3.281 feet), the
temperature should be from 20 to 25 °C (68 to 77 °F ) and the humidity should be more
or less 50 %.

WARNING
Be careful of using a battery as following:
Rechargeable lead battery is used as the emergency battery of PBX. Check the backup for an electricity failure.
Battery electrolyte is harmful to human body. If the battery electrolyte is put on the
cloth, clean it using enough amount of water.
Do not cause the battery short intentionally. Do not put it near fire or put it into fire.
Do not damage it, such as disassembly, falling, and impact.
The battery life varies depending on the surroundings. The battery life is approximately three years. If the battery is used outside with high temperature, the battery
life is shortened to approximately one year.
If not replacing terminal or dead battery, the PBX system will not work in case such as
power failure. Besides it might cause smoking or fire due to leaking battery electrolyte.
Perform the periodic diagnosis surely. Note that the battery is one of periodic replacement parts whose cost are charged to the customer. We recommend you to make a contract with supplier or service technician about the routine maintenance.
Do not touch the peripheral equipment by wet hand. Do not wet the peripheral equip-

ATTENTION
Do not use benzine, thinner, and alcohol for cleaning. When it is difficult to clean dust
and dirt, put weaken neutral detergent onto a cloth, and give the cloth a wiring. Clean
dust and dirt with the cloth, and rub them with a dry cloth.
Do not place equipment in the following:
Locations which receive direct sunlight
Locations where the moisture exceeds the allowed level
Locations which might be wet with water, oil, and chemicals
Locations which is particularly low in temperature (such as an ice compartment)
Locations which receive the electric wave or the magnetism from TV and (two-way)
radio
Locations which receive the illegal electric wave
Note that the life of PBX and Main Power is shorten if placed in the location affected
by much of hydrogen sulfide or salt, such as seaside area.
2.2 Notice Regarding Lightenning Strikes
WARNING
It is necessary to take proper procedures to avoid damage to the PBX caused by local lightening strikes
and other electrical surges.
As for grounding conductors, there needs to be two-type grounding conductors; one is below 10
(Type 1) and the other is below 100
circuit installment, therefore, it must be used as isolated system to keep from electricity difference
caused by lightening strikes.
The Type 1 is used when connecting the FE of PBX, the PE of Main Power, MDF, etc.
Extract the ground terminal (grounding electrode of three terminals) from the earth board same with
that of the main equipment. The ground terminal attached with AC100V plug outlet is used for MAT,
printer, MODEM, and measurement machine for maintenance.

CHAPTER 2 GENERAL INFORMATION FOR CCIS
1. GENERAL
This chapter describes the functional outline of CCIS, hardware required for CCIS, and service features which can
be provided by CCIS.
2. DESCRIPTION OF CCIS
The modular architecture and wide range of voice and data features available with the digital PBX’s have been developed with emphasis on continued enhancement within a single PBX. In order to meet the growing demand for
further enhancement on a network level, NEC developed a networking system employing Common Channel Interoffice Signaling (CCIS). The CCIS system links together individual PBX systems (nodes) to form a transparent
voice and data network which acts as a single large PBX, even though terminals within the network are, in fact, connected to different PBX’s. Common Channel Interoffice Signaling (CCIS) derives its name from the fact that a signaling channel (link), separate from voice and data channels, is provided between nodes for the sole purpose of
signal exchange. This signaling link is used in common by all voice and data links for exchange of information relating to addressing (e.g. dialed digits, calling/called number); supervisory functions (e.g. call setup and termination); and network accounting and management (e.g. centralized billing and fault reporting.) This is unlike
conventional tie line networks which exchange signaling information over the same links as are for voice transmission (Associated Channel Interoffice Signaling.)
The block diagrams in Figure 2-1 and 2-2 illustrate the difference between Common Channel Interoffice Signalling
(CCIS) and Associated Channel (In-band) Interoffice Signaling (ACIS).

Some advantages of the separate signaling link provided by CCIS are:
(a) Network Transparency
Because CCIS allows data relating to service features and station/trunk status to be exchanged between nodes
at a high rate of speed (64 Kbps), service is provided to all users as though the CCIS network was a single PBX.
(b) Centralized Facilities
Centralized Management: Fault messages from all nodes can be directed to one centralized (management)
node.
Centralized Billing: Billing information for all nodes in the network can be processed at one central
location.
Centralized Attendant Service: It is not necessary in a CCIS network to have an Attendant Console at each
node in the network. Attendant services can be provided to multiple nodes from
one or more central location(s).
(c) Better Utilization of Trunking Facilities
Because network signaling is carried over separate signaling links, more efficient use can be made for network
trunks (reduced call holding time, reduced connection time, etc.). In another word, the number of trunk circuits, which required to provide a specified traffic capacity, can be reduced.

GENERAL INFORMATION FOR CCIS
(d) Network Reliability
Alternate Routing provides the CCIS network with maximum reliability. If the signaling link between two
nodes should fail, signaling is sent over an alternate route, via another node, without loss of service. Directlyconnected redundant links can also be provided to assure the reliability of the network.
(e) Reduction in Personnel
Because management, cost accounting, and services, such as Attendant operation, can be centralized, the number of people necessary to administer the network can be reduced.
(f) Reduced Hardware
Signaling over a common channel; better utilization of trunking facilities; and centralized management and
services all result in a vast reduction in hardware when a CCIS network, rather than a conventional Tie line
network, is used.
3. SYSTEM CONFIGURATION
3.1 Outline
This Section describes the hardware configuration and its specification, the names of interface equipment and other
related subjects. Figure 2-3 shows No. 7 hardware configuration, respectively. The control signal circuit used for
CCIS is classified into the digital circuit and analog circuit. The CCH card can be used for both digital and analog
control signal circuit and the CCT card is used for digital one. CCH sends control signals to and receives from the
distant office. Also, for network synchronization, PLO/OSC or TSW (Phase Lock Oscillator/Oscillator or Time Division Switch) are used.
For the analog control signal circuit, CCH circuit card is used with MODEM.

4. NETWORK CONFIGURATION
With application of No. 7 CCIS added to the PBX, a network of multiple functions as if it were a single PBX.
Since calls can be freely transferred between one PBX and another, most of the existing station services can be ap-
plied to inter-PBX call connections.
Further, using the CENTRALIZED BILLING-CCIS service and the CENTRALIZED SYSTEM MANAGEMENT
REPORT-CCIS service, billing information and fault information can be processed at one center point instead of
processing at each PBX concerned.

of network configuration for CCIS Analog Line.

4.1 Types of Network
CCIS networks can be divided into the following types, depending upon the numbering plan used:
Main-Satellite Networks
Main-Remote/Campus Networks
Both networks provide uniformity of services throughout the CCIS network, and, because of numbering plan flexibility, station users are not conscious of the distance between nodes.
Main/Satellite Network:
In this type of network, offices are connected by means of a numbering plan consisting of a three-digit office code,
which denotes the location, and four-digit station numbers. An example of a Main/Satellite Network is shown in
Figure 2-6.
Main-Remote/Campus Network:
In these types of networks, offices are connected by means of a numbering plan consisting of four or five digit station
numbers. The first one or two digit(s) of these station numbers are used to denote the location. An example of a
Main-Campus Network is shown in Figure 2-7. Figure 2-8 shows an example of a Main-Remote Network. In this
network, a part of the Main Office is installed as a Remote Office at a nearby site, either within or outside the premises of the Main Office. An advantage of this network is that it requires far less cabling than would be necessary
if stations were connected to a single PBX. Network numbering specifications are summarized in Table 2-2.

4.3 CCIS Network Modes
The signaling channels of a CCIS network can be connected in one of two ways: Associated Mode or Quasi-Associated Mode.
4.3.1 Associated Mode
An Associated Mode network is configured with a signaling channel (data link) between all nodes in the network.
Signaling functions for all inter-node calls are carried over these dedicated signaling channels. In an Associated
Mode Network, if one of the signaling links should fail, signaling can easily be rerouted via another node. An example of an Associated Mode network is shown in Figure 2-9 below.

4.3.2 Quasi-Associated Mode
In Figure 2-10 below, nodes A and B, and A and C are connected in the Associated Mode. Nodes B and C are connected in the Quasi-Associated Mode.
In this configuration, signaling data between nodes B and C is routed via node A, while the communication channels
are established directly between nodes B and C. This type of network reduces the hardware necessary to establish
the signaling links.

4.4 CCIS Network Redundancy
To provide maximum network reliability, two levels of redundancy are provided for the signaling links.
(1) Signaling Channel Redundancy
Redundancy of the inter-node signaling links is provided directly between the nodes by adding one more link
than is necessary for the signaling traffic. This is the N+1 method. If one link fails, signaling is automatically
routed via an alternate link.
(2) Alternate Signaling Path Redundancy
An alternate method of providing network signaling redundancy is to configure the network so that an alternate
path is provided between the nodes.
In the network shown in Figure 2-9, if the signaling link(s) directly connecting nodes B and C should fail, the
signaling would automatically be reconnected via node A without loss of service. (Node A would be designated
as the Signaling Transfer Point [STP]).

5. DIGITAL NETWORK AND NETWORK SYNCHRONIZATION
5.1 Outline
To set up a digital network, it is necessary to establish clock level synchronization among the offices composing the
network.
Among various kinds of synchronizing methods, the PBX is using Receiver synchronization as the standard method.
As for the office ranks, there are the following four kinds:
• Source Office
• Sub-Source Office
• Receiver Office
• Local Receiver Office
Refer to Table 2-3 for synchronization method at network-level.
For types of PBX applicable for each office hierarchy, refer to Table 2-4.
