Classification of Functions Classification Function Group Blocking Explanation Content Station numbers (sequencial station numbers): max. of 8 groups The following system are available: is composed of station No. (1) Group can call group (2) Group can make zone No. (3) Group paging call Paging Zone 1 Group 1 Group 2 Group 3 Group 4 [1 ] A system can be divided so that a group of stations (up to 8 groups maximum) cannot call each other.
Automatic Line Release When, in dialing, all of the numbers are not dialed within 5 seconds, the station is automatically disconnected from the speech path and dialing cannot be completed. In this instance, the dialing process will have to be repeated from the beginning. This function has been adopted to speed up traffic processing and to improve the availability of speech parths.
Camp-On Privacy When the party you are calling has his station on Privacy mode, by simply waiting you will automatically "CampOn" the line. (Busy tone sounds continuously.) As soon as the Privacy mode is released, you will be automatically connected. This function is cancelled automatically if the station in the privacy mode may not accept the call within 10 seconds.
Personal Number Call A personal number may be registered at any master station which the person to whom the number is assigned expects to be. A party wishing to receive personal number calls at a specific station may register his number at that station by touch dialing Registration Personal Number. Those who are frequently away from their assigned station, as well as those who share a single station may be assigned a "Personal" 4-digit number which may be programmed to any master station in the system.
Single Digit Dialing Single digit registration Register in advance as follows: Single digits of station number Confirmation tone Station number (2 digits for 2-digit dial) Confirmation tone Single digit of personal number Personal number Confirmation tone Single digit of paging call Paging zone Confirmation tone 0: All call response 0 or 9 9 : Zone paging response Confirmation tone ( Single digit of paging response ) Any four digits Confirmation tone Any three digits Confirmation tone Any two dig
Master Sub Relationship Master/Substation associations are set up by using station #200 as the programming station. Once these relationships have been established, substations can then contact their designated master stations by simply touch dialing With respect to this function, the stations in the system are divided into two categories; master stations and substations. Any master station can be connected to any other station in the system.
Secretary Transfer This function is only available when a specified station is programmed for this purpose with use of Station #200 in the programming mode. Automatic transfer of incoming calls by an executive to his secretary is accomplished by placing the Privacy Switch on his station in the ON position. This function allows a secretary to accept all incoming calls placed to an executive.
Call Transfer Call Transfer from Called Station Call During the conversation, first dial Called Station (the Station Number of the person the call is to be transferred to). Calling Station Called Station The original call is then held and the holding tone is transmitted to the other party, while the third party is called and asked whether he will accept the call. If he agrees to accept the call, dial and the transfer will be completed.
Priority When the party called is on the line, as indicated by the busy tone, dialing transmits a priority tone to the called party. The same tone is audible at the calling station. The call is connected if the called party also responds by dialing Busy Tone Priority In this event, the original conversation partner of the party called is temporarily placed on hold and the holding tone is transmitted to his station.
Continuous Calling Tone When a specified station receives a call, the calling tone continues until PTT bar is depressed by this party. 1. When calls cannot be answered immediately or when it is difficult to hear a normal calling tone due to high background noise, the station should be provided with the continuous calling tone function. There is no limit to the number of stations that may be equipped with this function, but a No.
Conference A "Hands-Free" conference call can be made with up to 4 persons. For a conference under this function the other participants may be called either through their station number, personal number or by Single Digit Dialing. Addition of stations or personal numbers (total of only 4) may be added by anyone already connected. A "Hands-Free" conference call can be made with up to 4 persons.
Selectable Calling-Tone Duration The duration of the calling tone can be set for either a ''long" (1.3-second) or a "short" (0.7 second). Selectable Paging Pre-Announcement Tone Duration The duration of the all-call and zone paging tones can be set for either a "long" (2-second) or a "short" (1-second). Paging A variety of paging modes allows paging over a wide area from any master station. The paged party may respond from the nearest master station.
Other Paging Modes 1. Combination paging Combination paging is used when several zones must be paged simultaneously through External PA or Station paging. A special paging area can be created wherever the paging ranges overlap by combining several zones. A maximum of 10 combinations can be created in this way from a maximum of 1 5 individual zones. 2. Emergency all-call paging Emergency external PA or station all-call paging can be made either from the specified station (No.
How to select the paging area and make the paging call. Paging functions may includes both external PA and stations, depending on the zone being used. The paging area is limited to individual zone, Combination paging and All-call paging depending on the call range. Paging Dialing operation Paging Response Paging area External PA paging Station paging All-call and maximum of 7 zones paging All-call and maximum No. All-call paging 0 All-call and maximum of 7zone paging.
All-Call Paging and Individual Zone Paging External PA paging to a specific zone is possible from any master station by pressing and the desired zone number ('0' = all-call). It is possible to wait for a response in this mode, but anything said will be broadcast over the entire zone. It is best to end the paging call by pressing All-call paging Zone paging and waiting for a response.
Combination Paging < Example 1 > Several zones can be called simultaneously using external PA paging and station paging. This is combination paging and is initiated by pressing Combination zone 91 Combination zone 92 Paging will be broadcast to predetermined zones. It is possible to wait for a response in this mode, but it is usually preferable to terminate the paging call and wait for a response. The paged party can respond by pressing at the nearest station.
< Example 4 > To operate combination paging, No. 200 registration indicating the individual zones to be included in the combination zone-must be made. For further details, refer to Installation Hand Book for EXES-5000 CPU-55. Table of zones included in combination zones (Example) Combination zone 90 91 92 93 94 95 96 97 98 99 Emergency All-Call Paging The emergency all-call station, No.
Paging Priority When using the standard paging functions, paging is not heard while other calls are in progress. < Example > No.204 Holding tone Using paging priority: 1. Dial Interruption of call (zones: 1—7,all-call: 0), (zones: 01—15, all-call: 00), or (combination zones: 90—99). When the station being paged is already on the line, the call is interrupted. And the calling party is put on hold while the paging message is delivered. 2.
Note 1: If the station called is in the process of dialing when station paging is initiative, paging will not be heard at that station and the call can be completed without interference. Note 2: If a station being paged with station paging is called by a third party, camp-on-busy will result. Note 3: If any station in a given zone (zone 1, for example) pages another zone (zone 2, for example), station paging to stations in zone 1 results in camp-onbusy.
Programmable Station Numbering This function allows the system to have "Programmable station numbers", other than the "Hardwired station numbers" by programming. The unprogrammed stations (unit station numbers) are used as original hardwired station numbers. Hardwired station number Programmable station number 3-digit dialing No.200~32 7 No.200~99 9 2-digit dialing No.20~9 9 No.20~9 9 1. Numbering schedules can be changed easily by programming in stead of rewiring. < Example > 2.
Group Blocking Function (A) . . The system can be grouped or divided into a maximum of 8 groups of stations with sequencial station numbers. Stations in the group cannot call another. Group 1 Group 3 Group 2 No.220~24 9 No.210~21 9 Function (B) . . The group can call and/or be called by any other group(s) by programming. < Example > No.201~20 9 Group 4 No.250~27 9 Calling station Group 1 Group 2 Group 3 Group 4 Station receiving Function (C) . .
Programmable Restricted Access for Stations Stations which can use the following functions must be programmed, so as to restrict access to those functions by those stations not programmed. 1. All-call paging 2. Conference Station number 3. General purpose control Model (One-shot make output) 4. General purpose control Mode 2 (Make/break output) 5. General purpose control Mode 3 (8 selectable output or decimal output) 6. General purpose control Mode 4 (4 decimal digits output) 1.
In/Out Annunciation The in/out annunciation indicators can be turned on or off from any master station by using the personal number registering procedure. When a personal number registeration is made at a station, by dialing In/out indication panel Lamp on 1000~1499(personal number) the personal number is registered at that station and the personal number lamp on the in/out indication panel is turned on.
Calling Party Indication (7-SEG Display Type) A numerical type calling party indication panel can be provided for certain specified stations (32 stations from No. 200 to No. 231). 1. The party receiving the call is indicated in the area for the calling station number with 7 segment display. 2. When a call is made to the busy or the privacy station (with the privacy switch on), the number of the calling party is indicated in the area for the waiting station and as a 1 in the number of waiting stations area.
General Purpose Control Station may be restricted from access to this function. This function can control other equipments by employing the Data Transmitting and Receiving Units. Select the required type of output. (Mode 1) One-shot make output Dial (000 ~ 499, max. of 500 contacts) and the relay output is made for 1 to 2 seconds. Example: Door remote and VTR control Note: Operation performed even when all link circuits are occupied.
