    System Features


    The system shall be an IP network compatible intercom system that employs packet audio technology. It shall be capable of connecting exchanges, IP network audio adapters, IP amplifiers, IP active loudspeakers, IP paging stations and various interface units to a local area network (LAN), wide area network (WAN) or fiber-optic network. The system shall be designed to allow duplex conversation between stations, paging broadcasts, timely broadcasts, background music broadcasts, etc. Up to 5,000 IP stations, intercom panels and various interface units shall be capable of being connected per system. The system shall feature an echo cancelling function that prevents acoustic feedback and echo in order to make possible full-duplex hands-free conversations between stations. The system shall features of separate IP station with intercom and IP station with several intercom panels for both standard and economy options. Additionally, the use of IP stations shall allow the construction of system that can operate without an exchange. The system shall could be constructed over the existing network system or dedicated network system. Both centralized control and decentralized control of the system shall be possible using a PC sever or several PC servers with dedicated ITC software installed.

System Programming

    System programming shall be accessible to the contractor and the end user to reconstruct of the system vary from needs. System programming shall be accessible from a Windows PC computer on the same Ethernet network as the intercom exchange, running the dedicated setup software. Setup software shall be protected by a password. Stations that can be connected directly to the network shall be accompanied by the system's dedicated CD-ROM software. Limited programming feature shall be available through a web browser shall enable users to change network settings, to know the current operation status and line status and to view operation and stream logs. (Recommended browsers: Internet Explorer 6/Internet Explorer 7/Internet Explorer 8)


    Dialing a station number of two to six digits in length shall establish an immediate communications link between two stations within a system. The number of dialing digits shall be established using the system setup software.

Station Numbering and Naming

    It shall be possible to assign or change station numbers and alphanumberic names via the setup a software. A simple programming sequence shall be used without the need to open, disable or disassemble the system hardware.

Reception Mode

    In this system either of the following two reception modes shall be selectable:Sequential response

    (Master-to-Master System). This method shall mainly be used by master stations and suitable for

    "Master-to-Master" systems that enable free calling. Its main applications shall include communication and paging, and responses to calls shall be made on a first-come-first served basis. Selective response

    (Master-to-Sub System). This method shall mainly be used by substations or door stations and shall be suitable for "Master-to-Sub" systems in which many substations call a master station.

Call from Substations

    Pressing the substation's call button shall call up the preprogrammed master station or analog telephone connected to the telephone interface unit.

    - 3 -

Emergency Calls

    The door station and substation shall allow emergency calls to be made by performing emergency call-up operation. The master station receiving the emergency call shall sound an emergency call tone and provide an emergency call display by indicator and by message both.

Door station

    The door station shall be have different options for indoor use and outdoor use, which allow emergency call to be made by pressing the button. While additional service inquiry call shall be allowed to made when service button is pressed. Two different door station which integrate with and without encoder and decoder are available for different solutions.

Priority Calls

    Eight different priority levels shall be cable of being assigned to door stations and substations, and calls from such stations shall be displayed on the called master station in order of such priority.

    - 4 -

Standard Features (No Progamming Required)

Automatic Line Release

    The system shall release the speech path if dialing is not completed within five seconds.

Camp on Busy

    A calling party shall be able to wait or "camp-on" if the called station is busy. Once the called party becomes available, the camped-on party shall be automatically connected.

Push to Talk and Release to Listen

    On way conversation shall be available by using the PUSH-TO-TALK key. Releasing the PUSH-TO-TALK key shall reverse the one way conversation. The PUSH-TO-TALK key shall have precedence over the voice switched mode.


    A master station's microphone shall be mutable during conversation. This function shall hold a call in progress without interruption and without forcing the user to re-establish the call.

Auto-Dialing (Single Digit Dialing)

    The multifunctional master station shall have the ability to enable preprogrammed Auto Dial key operation of up to 20 digits with the touch of a single button.


    A master station shall be able to redial the last conversation partner by pressing a designated key.

    ; All Call Paging This function shall allow simultaneous paging to all programmed paging groups


    ; Emergency All-Group Paging This function shall terminate all concurrent conversations, paging and

    other ongoing operations, allowing all stations and units designated as paging output destinations to

    be simultaneously paged.

Paging Methods

    ; Station Paging Paging of individual stations shall be possible. However, only IP stations shall be

    capable of being pre-programmed by the setting software for precedence priority when pages and

    normal calls are simultaneously received.

    ; PA Paging by Way of External PA Equipment This function shall allow paging to be initialed through

    PA equipment connected to the exchange's paging output terminals or the multi-interface or audio

    interface unit's audio output terminals.

    ; External Input Paging This function shall allow audio or music from externally connected equipment

    to be broadcast by way of the multi-interface and audio interface units.

Station Paging Reception Mode

    If a paged party dials a paging response number at a nearby station, that party shall then be directly connected to the station where the page initiated.

One-Touch Dialing

    A master station shall have the ability to dial up to 32 digits by the touch of one button. Then simply pressing an abbreviated number shall enable dial operations such as paging activation and call transfer.

Unanswered Calls

    ; No-Answer Call When a call is received at a station programmed for "No-Answer Call Forwarding", if

    no response is made fro a specified period of time, the call shall be automatically transferred to

    another pre-designated station.

    ; Busy Call When the designated station to which a call was transferred is busy, the call shall be

    automatically transferred to the next designated station, and this shall continue in series until a free

    line is found.

    ; Call Forwarding When a call is received at a station programmed for "Call Forwarding", the call shall

    be automatically transferred to another pre-designated station without sounding a call tone. Either

    of the two following modes for placing the station in call forwarding mode shall be selectable: 1)

    One that instantly sets the station for the call forwarding mode by manually designating the station

    to which a call is to be transferred. 2) One in which the station is automatically placed in the call

    forwarding mode when the pre-programmed time is reached.

    Dial Operation

    The following selection shall be made possible to determine dialing sequences for station dialing and paging response.

    ; Station dialing numbers shall be independent of connected exchange number or other hardware

    - 6 -

    configuration. Station numbering shall be programmable as two to six digits in length. ; Paging zone numbering shall be programmed as single, double or triple digit.

    ; Paging response shall be accomplished by pressing the paging response key or by pressing the

    paging response key plus the zone number.

Group Blocking

    The system shall support the inclusion of stations into any of 500 groups. These groups shall be prohibited from calling or paging each other unless specifically allowed via system programming.
