IP Network Intercom Exchange

IP NETWORK INTERCOM SYSTEM

DESCRIPTION FEATURES

The N-8000 Series comprises a complete network-based intercom system that makes it possible to achieve efficient wide area coverage with high-quality audio through a network, even with the most remote locations. The system includes a main exchange unit that can handle up to 16 dedicated stations. The system provides a full range of communication features and functions such as: Redial, Recall, One-touch dialing/Auto-dialing, Group Call, Group hunting/Absence transfer/Call Forwarding, Call Hold, and Scan Monitor. Stations are also available in various configurations to suit specific applications and depending on model, provide such features such as LCD display, hands-free operation, and heavy-duty design for severe environments. Convenient station paging is possible as each station has a built-in speaker and by using an external amplifier, PA paging is also possible. The system can broadcast to a total of 160 zones with paging as well as provide all-zone paging. The system can also be expanded as desired to a maximum of as many as 1,280 stations. In addition, since the system is network-based, maintenance is simplified with a personal computer able to perform all maintenance tasks. The increasing prominence of networks makes it possible for TOA to develop advanced and cost-effective communication products.

A network-based intercom system consisting of an exchanger unit and dedicated station.

A single exchange unit can connect up to 16 stations. Stations are available in four different configurations. These are: N-8000MS (with LCD display), N-8010MS (standard), N-8011MS (hands-free calls), and N-8020MS, which is a heavy-duty type designed for use in adverse environments such as factories and various plants (dust- and water-resistant: IP54).

This system is equally suitable for use in a small-scale system with 16 stations to meeting the demands of a large-scale system that can have as many as up to 1,280 stations. Once the intercom is connected to a network, efficient wide area connections even between remote locations can be achieved.

The system includes convenient functions and features such as: Redial, Recall, One-touch dialing/Auto-dialing, Group Call, Group hunting/Absence transfer/Call Forwarding, Call Hold, and Scan Monitor.

Using the echo canceller function makes hands-free simultaneous conversation an easy task.

High quality audio with frequencies extending to 7kHz* for extra clarity is possible.

Stations incorporate a built-in speaker, which allows station paging. PA paging can also be conducted using an external PA amplifier. Total broadcast capabilities of up to 160-zones with paging and All-call paging are possible.

Total system maintenance can be conveniently performed through network using a personal computer that has TOA,s dedicated software installed.*network status may sometimes cause audio quality to deteriorate to about 3.4 kHz.

N-8000EX IP Network Intercom Exchange

The IP Network Intercom Exchange uses packet 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 stations. 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.

Function Description

[Conversation]

Hands-free Permits conversations to be made without lifting the handset conversation when another party is called or when a call is received in

automatic connection mode.Handset Calls can be made or received by lifting the handset.conversationPTT conversation Pressing the PTT key during a conversation enables one-way

conversation from the party who pressed the PTT key. Conversation flow is reversed when the key is released.

[Call]

Individual call The desired party can be called by dialing its station number.Redialing Pressing the Redial key automatically redials the last number

called. Only the N-8000MS Multifunctional Master Station permits selection from the most recent 10 numbers.

Recall The last conversation partner can be recalled by pressing the [#/] key regardless of whether the call was made or received. Only the N-8000MS Multifunctional Master Station permits selection from the most recent 10 numbers.

Voice calling Holding down the PTT key while making a call by means of a continuous call tone permits a voice calling to be made to the called station. The voice calling reverts to the original continuous tone call when the PTT key is released.

Group call When a station is assigned to a call group, if the station is called, all stations within that group are simultaneously called by a continuous call tone regardless of their call connection mode settings. If any one of the stations within the group responds, calls to the other stations stop.

[IncomingAutomatic Incoming calls are automatically connected after a brief call

Callconnection tone (1 second) or without a call tone.

Selection]Continuous call Calls continue with a continuous call tone (or without a

call tone) and a status indicator continuously flashesas long as no response is made.

[Speed

Auto-dialing The most frequently used station numbers (of up to 20 digits)

Dialing]

(N-8000MS only) programmed into the station's auto dialer can be called by one-touch dialing.

One-touch dialing Pre-programming a number (up to 20 digits) into the station's [7], [8], [9], [0] keys or off hook permits that number to be automatically called by one-touch dialing the corresponding key.

[Hold]

Mic Off When it is desirable to hold the line during a conversation, if any dialing key ([0] - [9]) is pressed, the microphone is disabled as long as the key is pressed.

Call hold Pressing the Hold key during a conversation places theconversation on hold, transmitting a hold tone to both parties. If the Hold key is pressed again, the hold mode is cancelled, and the original conversation is restored.

Function Description

[Call transfer]Current conversations can be placed on hold to call a third party by pressing the Transfer key. The original conversation can be subsequently restored or transferred to the third party after conclusion of the second call.

[Automatic

Group hunting Calls to a busy station are automatically transferred to another

Transfer]

designated station, if group hunting function is set to the called station.

Absence transfer When no response is made to a call for a set period of time, the call is automatically transferred to another designated station.

Call forwarding Calls to stations are automatically transferred to another designated station without sounding a call tone. Two different modes are available: one is call forwarding, in which calls are manually rerouted to the selected station, and the other is time-based call forwarding, which transfers calls only when the preset time is reached.

[Remote Response]Calls to a station can be answered by pressing the PTT key of another station, provided both stations are assigned to the same group.

[Executive Priority]

If a called station is busy, as indicated by a busy tone, pressing the [9] key transmits a short priority call tone, then forcibly terminates the current conversation, allowing the call to go through. Access to priority call operation or refusal of prioritycalls can be set individually for each station.

[Scan Monitor] The station can scan an arbitrary group of preprogrammedstations for auditory monitoring.

[Paging]

Zone paging Calls can be made to one of the pre-programmed zones.Paging Calls can be made to up to 10 zones of the preprogrammed

multiple zones.All-call paging Calls can be made simultaneously to all of the preprogrammed

zones.[Station Speaker Output Setting] Permits adjustment of the station speaker sound volume.

[Ambient Noise Control] Automatically measures the ambient noise level of the station and sets the station for proper hands-free conversation.

[PagingAutomatic response Dialing the Paging Response key automatically initiates a

Response]response to the paging last received.

Zone number response Dialing the number assigned to paging response automatically initiates a response to a next-to-last paging.

Time-outThe duration of calls, conversations and paging can be limited by pre-programming time intervals (10 - 990 seconds) for individual exchanges.

Group blocking Arbitrary station groups (up to 31 groups) can be set to permit or

disallow calls between groups.
