2. GENERAL DESCRIPTION
TOA's N-8000EX and N-8010EX are exchanges used for the N-8000 Series Packet Intercom System (IP
network compatible intercom) employing packet audio technology*1. By connecting IP intercom exchanges
(which permit connection of up to 16 stations per exchange) to a network (LAN or WAN), an optimal system for
in-house or wide area information communications, such as duplex conversations between stations and paging
broadcasts, can be constructed. Since up to 80 exchanges can be combined, systems of up to a total of 1,280
stations can be realized. The system's "echo cancellation"*2feature makes hands-free duplex conversation
possible (conversations made without using a handset at both parties) between stations.
*1 Technology related to audio transmission over a network.
*2 A circuit that prevents acoustic feedback or echo generated when the voice output from the station's internal
speaker enters the microphone.
Warning
This is a class A product. In a domestic environment this product may cause radio interference in which case
the user may be required to take adequate measures.
DESCRIPTION GÉNÉRALE
Les unités N-8000EX et N-8010EX de TOA sont les centraux utilisés pour le système de paquet intercom
des séries N-8000 (intercom compatible avec un réseau IP) utilisant une technologie de paquet audio*1. La
connexion de centraux intercom IP (qui permettent la connexion de 16 stations maximum par central) à un
réseau permet d'installer un système optimal pour les communications internes ou au sein d'une zone étendue,
par exemple dans le cas de conversations en duplex entre stations et de l'envoi de notications. Il est possible
de combiner jusqu'à 80 centraux, ce qui permet d'installer des systèmes comptant jusqu'à 1280 stations. La
fonctionnalité de suppression de l'écho*2du système rend possible les conversations mains-libres en duplex

7. INSTALLATION
The exchange can be installed in any of three ways: Equipment rack mounting, Desk-top installation, and Wall
mounting.
7.1. Rack Mounting
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required
for safe operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g. use of power
strips)."
A) Température ambiante élevée - si l’appareil est installé dans un bâti fermé ou en même temps que
d’autres appareils, la température à l’intérieur risque de devenir supérieure à la température ambiante. Par
conséquent, veiller à installer l’équipement dans un environnement compatible à la température ambiante
maximum spéciée par le fabricant.
B) Débit d’air réduit - L’installation de l’équipement en bâti ne doit pas compromettre le débit d’air nécessaire à
une utilisation sûre de l’équipement.
C) Charge mécanique - Le montage de l’équipement en bâti ne doit pas entraîner de danger dû à une surcharge
mécanique inégale.
D) Surcharge du circuit - rester vigilant lors de la connexion de l’équipement au circuit d’alimentation et
aux conséquences d’une surcharge des circuits sur la protection contre les surintensités et les câbles
d’alimentation. Tenir compte des indications de la plaque nominale de l’appareil.
E) Veiller à toujours garantir l’intégrité de la prise de mise à la terre. Faire particulièrement attention aux
connexions d’alimentation en dehors des branchements directs au circuit de dérivation (par exemple à l’aide
de multiprises).
The Exchange can be mounted on the CR-273 or CR-413 or standard EIA 19" Equipment rack.
These racks, when fully equipped with exchanges, can provide the following capacity of stations: 128 stations
for one CR-273, 192 stations for one CR-413, and 1,280 stations for seven CR-413s.
For the CR-273 and CR-413 Equipment rack assembly or BU-412 Blower unit installation, read the installation
manual supplied with the rack.
Note
When installing the blower units, terminal
boards, and exchanges, lay the equipment
rack down face-up to do installation work
safely. Since the blower unit is installed from
the inside of the rack, be sure to install it first,
before mounting the other components.

The types of cables are to be determined according to the following conditions.
• Twisted pair wires (such as those used for electronic push-button telephone) are to be used for wiring between
the Exchange and the stations in principle.
• UTP category 5 Straight through cables with RJ45 connector are to be used for connecting to IP network.
• The number of cables pairs laid should be determined considering the possibility of future expansion of the
system.
• Outdoor wires should be used where wiring passes through inaccessible areas such as ceilings or under
oors where the maintenance is not performed. Indoor wires may also be used, however, in case where there
is no risk of deterioration due to exposure to heat, etc.
Note
Specifications related to each junction are as follows.
Mini-clamp connector (N-8000EX/8010EX line terminal)
Conductor diameter: ø 0.4 – 0.65 mm (AWG22 – 26), Solid wire
Outside diameter: ø 1.05 mm or below
Clip terminal (E-7000TB)
Conductor diameter: ø 0.4 – 0.8 mm (AWG20 – 26), Solid wire
Outside diameter: ø 1.5 mm or below

8.4. Connector Connection
The N-8000EX comes with mini-clamp connectors for line terminals and detachable terminal plugs for paging
output terminal, while the N-8010EX comes with mini-clamp connectors for line terminals.
Perform each connector connection as follows.
8.4.1. Mini-clamp connector connection
Connect the mini-clamp connector supplied with the N-8000EX to a cable using a commercially available tool
(pliers).
Step 1. Cut off two-cable ends in equal length, and insert them
securely to a cover section (transparent side) of the
mini-clamp connector.
Note
Insert the cable without stripping the cable jacket.
For cables, refer to p. 16, "Type of Cable."
Step 2. With a pair of pliers, lightly pinch the mini-clamp cover
and, after ensuring that the cable is securely inserted,
rmly squeeze on the cover.
Note
Squeeze on the mini-clamp cover until it is correctly locked.
Step 3. Insert the wired connector (plug) into the exchange's connector (socket) until it locks into place.

8.4.2. Removable terminal plug connection N-8000EX only
Step 1. Strip a cable jacket of approx. 7 mm to expose inner cable.
Step 2. Loosen the terminal screws and insert the cables.
Step 3. Tighten the terminal screws securely.
Notes
• Tug lightly on the cable to be sure that it does not pull free. If the cable pulls free, loosen the terminal
screw again and reconnect from Step 2.
• Use the screwdriver appropriate to the screws tightened into the terminal plug.
Step 4. Insert the wired terminal plug into the terminal block of the N-8000EX.
For cables, refer to p. 16, "Type of Cable."
Note
Do not solder plate on exposed inner cables when using a stranded wire.
