IP NETWORK INTERCOM SYSTEM
DESCRIPTION FEATURES

●
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), 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.
A basic N-8000 Series system is comprised of an intercom
exchange unit such as the N-8000EX IP Intercom Exchange.
Stations are available in different configurations with different
features:
Master Stations: N-8000MS Multifunctional Master Station,
N-8010MS Standard Master Station, N-8011MS Hands-Free
Master Station, N-8020MS Industrial Use Master Station,
N-8031MS Wall Mount Master Station and for network
applications, N-8500MS IP Master Station.
Door Stations: N-8050DS Door Station, N-8540DS IP Door Station
Up to 80 exchanges, multi interface units and IP stations can be
combined. When 80 exchanges are used, systems of up to 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. 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
A circuit that prevents acoustic feedback or echo generated when the voice
output from the station's internal speaker enters the microphone.
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.
Two types of exchanges are available:
N-8000EX; 4 internal and 8 external speech links with
PA paging output.
N-8010EX; 1 internal and 2 external speech links
without PA paging output.
System configured employing IP stations make communications
possible without having to use an exchange unit.
(IP Door Stations alone cannot be configured into systems
without incorporating a IP Master Station.)
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.
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 E&M lead signaling interface.
The Multi Interface unit can interlock with an electronic lock
system or CCTV surveillance system by way of contact
input/output control function.

IP Network Intercom Exchange
The IP Network Intercom Exchange uses paket audio technology to
permit connection of up to sixteen N-8000 Series stations, and
features two outputs for public address paging. Simultaneous hand-
free conversation is possible between staions. Moreover, the
exchange is equipped with a networking interface, allowing up to 80
exchanges to be connected over a network using additional network
intercom exchanges. The Exchange can be mounted in an EIA
standard rack (1-unit size) or to a wall using the supplied bracket.

N-8000MI
Multi Interface Unit
The N-8000MI is a multi-interface unit designed for use with TOA's packet
intercom system (IP network-compatible intercom system) that employs the
packet audio technology. Connecting the multi-interface to a local area
network permits the ideal system for in-house or wide-area information
transmission applications, such as paging, periodical broadcasts, and
background music broadcasts, to be built between the multi-interface and
IP intercom exchange or other multi-interface unit. The contact bridge
function can be realized through contact input and output control. The
N-8000MI also features the tie-line function to be connected the the
EXES-2000 intercom system or the EXES-6000 system. A total of up to 80
multi-interface units and IP intercom exchanges can be connected to a
network. The unit can be mounted in an EIA standard rack (1-unit size) or
to a wall using the supplied bracket.
