1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe
operation.
• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or
cautions regarding safety.
• After reading, keep this manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual rst and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
CAUTION
• Use the specied AC adapter and PoE switching hub for the unit. Note that the use of another adapter and
PoE switching hub may cause a re. (N-SP80MS1 only)
• Avoid touching the unit’s sharp metal edge to prevent injury. (N-SP80VS1, N-SP80AS1, and YC-400)
• Use the 12 V DC power supply and PoE switching hub for the unit. Note that the use of another adapter and
PoE switching hub may cause a re. (N-SP80VS1 and N-SP80AS1 only)
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
2. GENERAL DESCRIPTION
The N-SP8 0 se r i e s intercom system is de s i g n e d for use in combination with the SI P (Session Init i a t i o n Protocol)
Intercom system.
This system consists of the Android based touch panel multimedia stations and the door stations. The door
station is available in 2 models: the one with camera and the one without camera.
The system can be used not only in SIP server mode but also in peer-to-peer mode: the former enables the
system to work by connecting to the SIP server and the latter enables it to work without using the SIP server.
In this manual, the N-SP80MS1 is described as the multimedia station, and the N-SP80VS1 and the N-SP80AS1
are collectively described as the door station.
Note: Android is a trademark of Google LLC.

3. FEATURES
• Fully compliant with SIP.
• Connected to the network via Ethernet.
• The door station with camera is compatible with ONVIF.
• Supports 2 ways of connection: Connection to the SIP server using SIP and peer-to-peer connection.
• Supports the following audio codecs: G.711, G.722, and G.729.
(Audio codec is xed to G.722 when in peer-to-peer connection.)
• Can be powered by means of PoE or from the DC power supply unit.
• The camera incorporated in the door station with camera has 3 mega pixels, featuring the built-in infrared light
that allows images to be taken at night.
• The built-in acoustic echo canceller ensures full duplex conversation for the door stations.
• The door stations are equipped with a relay output function. Relay control can be performed from a multimedia
station or other SIP telephones.
• The door stations are equipped with an external control input function. Different types of calling can be made
when an external control switch is connected.
• The multimedia station is easy to operate on the screen thanks to a touch panel and GUI (Graphical User
Interface) design, and in addition, usable as a telephone by intuitive dial operation with a ten-key pad.
• The multimedia station is selectable one of 3 conversation methods: handset conversation, hands-free
conversation, and headset conversation.
• Compatibility with CUCM obtained by Cisco systems.
• Easy conversations between stations even under high noise environment.

countries.
4. HANDLING PRECAUTIONS
The transmission quality of the internet is not always guaranteed.
Therefore, when this system is connected via the internet, the following symptoms may happen when the
network is congested.
• Packet loss
• Interruption of speech voice
• Generation of noise

5. USAGE MODE
5.1. SIP Server Mode
Each equipment of this system is in full conformity with SIP and can be used in connection to the SIP server
(Telephone system). The SIP server mode refers to the system when connecting to the SIP server. The
connection to CUCM by Cisco Systems and Asterisk by Digium is conrmed for the N-SP80 series. Since the
supporting version and the SIP server need to be updated, check for the latest information on the TOA product
data download site (https://www.toa-products.com/international/).
Note: Asterisk is a trademark of Digium, Inc.
[Features of SIP server mode communication]
• Audio signals are directly communicated between stations.
(They may be communicated via the server.)
• The maximum number of the stations to be connected
depends on the SIP server's specication.
• Communications are centrally controlled by the server.
• Transfer function can be used depending on the SIP server's
specication.
• Connection to the outside line is possible depending on the
SIP server's specication.
[SIP server mode]
SIP server
5.2. Peer-to-Peer Mode
The devices of this system can be directly connected with each other without using the SIP server. Peer-to-Peer
mode refers to the system or the state where the stations are directly connected with each other without using
a SIP server.
[Features of Peer-to-peer mode communication]
• Multiple one-to-one communications can be made
simultaneously, enabling the number of the connectable
stations within the system to be unlimited.
• SIP server is not used, allowing suppression of introduction
costs.
• A 3 party conversation can be made.
• Audio codec is xed to G.722.
