Chapter 1: GENERAL DESCRIPTION
1. GENERAL DESCRIPTION
The N-8000 Series is a packet intercom system (IP network compatible intercom) employing packet audio
technology*
1 . By connecting IP intercom exchanges (which can connect up to 16 stations per exchange),
Multi interface units, and IP stations to a network (LAN or WAN* 2 ), an optimal system can be constructed for
in-house or wide area information communications such as duplex conversations between stations, periodical
broadcasts, and BGM broadcasts. Since up to 80 exchanges, multi interface units and IP stations can be
combined, systems of up to a total of 1,280 stations can be realized. The system's "echo cancellation"*
3
feature makes hands-free duplex conversation possible (conversations made without using a handset at both
parties) between stations. In addition, the multi interface unit features a contact bridge function to be
performed by way of contact input and output control.
* 1 Technology related to audio transmission over a network.
* 2 The fixed global IP address must be assigned to the units connected via the Internet.
* 3 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.
2. FEATURES
• Exchanges, Multi interface units, and IP stations can be distributed over a data communications network.
• Can be connected to an existing local area network (LAN) or wide-area network (WAN). The system can
also be easily connected to fiber-optic networks without restrictions on operating distance.
• The dedicated software program enables centralized control with a personal computer.
• System maintenance (verifying operation log and Line supervision) can also be performed with a personal
computer and Internet browser.
• Both types of exchanges differ in the following points.
N-8000EX: Internal 4 links* 4 , external 8 links* 4 , with PA paging output
N-8010EX: Internal 1 link* 4 , external 2 links* 4 , without PA paging output
• Can be connected to the Exchange of the EXES-2000 or EXES-6000 Intercom System by a tie-line, or the
PBX exchange via the analog E&M interface.
• The Multi interface unit can interlock with an electronic lock system or CCTV surveillance system by way of
contact input/output control function.
• Using IP stations permits a system having no exchange to be created. However, the system configured only
with IP door stations cannot be realized.
* 4 Link is a speech path. The "internal 4 links" means that 4 simultaneous calls can be performed between
the stations connected to an exchange or 4 different broadcasts can be simultaneously made in a system.
The "external 8 links" means that 8 simultaneous calls can be made to the stations connected to other
exchange or to IP stations, or 8 different broadcasts can be simultaneously made to other exchange
system.
3. HANDLING PRECAUTIONS
The Internet is not guaranteed quality. So, when this system is connected to the Internet, packet loss may
result if the network is congested, possibly causing voice communications to be interrupted or noise to be
generated.
