Chapter 1 GENERAL DESCRIPTION
2. FEATuRES
• Exchanges, IP stations, and various kinds of interface units can be connected 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.
• 3 types of exchanges differ in the following points.
(1) 2-wire system
N-8000EX: Internal 4 links*, external 8 links*, with PA paging output
N-8010EX: Internal 1 link*, external 2 links*, without PA paging output
(2) 2-core shielded system
N-8000RS: External 2 links*
N-8010RS: External 1 link*
(3) 4-wire system
N-8400RS: External 2 links*
• 4 types of stations are available: 2-wire system, 2-core shielded system, 4-wire system and IP-type stations.
The first three stations must be connected to a corresponding system exchange to make operation possible,
while the IP station can be operated on its own without being connected to any exchange. (However, the
system configured only with IP door stations cannot be realized.)
(1) IP-type
(2) 2-wire system
(3) 2-core shielded system
(4) 4-wire system
• There are five types of interface units as shown below:
(1) Multi interface unit
(2) Audio interface unit
(3) Direct select unit
(4) C/O interface unit
(5) Telephone interface unit
• The Multi interface unit or Direct select 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.
• Using IP interface modules permits broadcast to the SX-2000 system.
* 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.
