APPLICATION NOTEAN-0103May 2000Loud Ringer Activated by AuxiliaryRing ContactsFor Norstar/BCM Auxiliary RingContacts; Dry ContactsThe Norstar KSU/BCM MSC auxiliary ring contacts can be programmedto activate on a station basis or trunk/line basis.These contacts are usually the first choice for adding a LoudRinger to a telephone system due to the ease of installation andprogrammability. For example, the contacts can be programmedto activate whenever a particular telephone, or group of telephones,ring.Installing a ringer directly to the telephone may provide limitationson wiring distance, require specific ring volume settings,or be more costly. However, as there is only one set of contactsper system, once the contacts have been utilized for a particularfunction it becomes necessary to install a ringer directly to atelephone, as described in other Application Notes.A station wire carrying the dry-contact closure on one pair andthe power on a separate pair is required between the equipmentroom and the Algo 1825PM Duet Plus location.

APPLICATION NOTEAN-0104May 2004Announcing a Doorphone Visitor Call(Loud Ringer)For Norstar/BST DoorphonesThe Norstar/BST Doorphone can be programmed to providepage chimes and/or to ring telephones when its call button hasbeen pressed. Sometimes, however, it may be desirable toannounce that a visitor has arrived with (for example) a ringer ina warehouse. This would allow personnel to simply answer thedoor if they are nearby or to differentiate between intercom anddoorphone calls.The optional Door Opening Controller (available from NortelNetworks) is capable of providing a dry-contact closure wheneverthe call button of the Norstar Doorphone is pressed. Thiscan be used to activate the 1825PM Duet Plus ringer (or the1826P Talking Duet Plus ringer with programmable announcements).In the diagram at right, power supply connections are omittedfor clarity. The Door Opening Controller requires a separatepower supply that has not been added to the requirements section(due to the fact that the power supply included with the 1825PM Duet Plus can provide power for the DoorOpening Controller as well).Requirements• A0518264 BST Doorphone(or Nortel Norstar Doorphone)• AO618971 Door Opening Controller (Nortel)• 1825PM Duet Plus• 1185 Horn Speaker (optional)• Pre-wire Learn More• Overview of Loud Ringing Solutions and Configurations (See Application Note AN-0112 on page 13)Algo Communication Products Ltd. 5 www.algosolutions.com1-877-884-2546 (USA & Canada) (604) 454-3790

APPLICATION NOTEAN-0401Jun 2006Analog Station Message WaitingIndicatorThe Meridian 1 /CS 1000 PBX (or a Norstar/BCM Analog Stationport) can provide a pulsed voltage across tip and ring formessage waiting indication, which normally illuminates a smalllamp in an analog telephone. This is often an insufficient notification and thus a brighter and more visible alertingis required.Algo provides two different solutions for message waiting indicationon an analog station:1. Using the 1825 Duet Plus and the 1081 MessageWaiting ModuleBy adding a specially designed input module (Algo 1081) intothe 1825PM Duet Plus, the Duet Plus will be activated by themessage waiting pulses. If an audio alert is required, this initself could provide the solution. However, for visual indication,the Duet Plus speaker can be disabled and the output usedinstead to activate either the 1127P Desktop Visual Alerter orthe 1126P Strobe Light.

APPLICATION NOTEAN-0404Jun 2006Overview of Visual Message WaitingIndicationA highly visible message waiting light is an essential part of anytelephone system equipped with voice mail. Such a light canensure important messages are immediately noticed andpromptly heard, thus minimizing the cost and frustration oflengthy communication delays.While most telephones display message waiting events on asmall text screen or light indicator, these indications are not adequatefor many users. Consequently, they often don't getnoticed. For example, a lab technician or supervisor, who frequentlyworks some distance from a telephone, may requirehighly visible notification from a distance that they have a voicemail message.Algo offers two basic solutions for Visual Message Waitingindication that are compatible with Nortel Digital, MeridianDigital Centrex, IP Softphone 2050, and Analog telephones:The Algo 1127P Visual Alerter and the Algo 1126P StrobeLight, both of which can be used interchangeably depending onthe application.Nortel Digital, Meridian Digital Centrex,IP Softphone 2050, and Analogtelephones The 1127P Visual Alerter is a desktop light that provides a highly visible green, blue or red light that is noticeablefrom all directions, with one of four distinct light patterns as selected by the option switch. The 1127P can belocated on the desktop, on a cubicle wall, on top of a computer monitor, or anywhere else deemed desirable.For brighter wider area notification, the Algo 1126P Strobe Light canbe used. This is a high-intensitylight idealfor warehouses or call centers. Algo Communication Products Ltd. 27 www.algosolutions.com1-877-884-2546 (USA & Canada) (604) 454-3790

When the button is released (Normalmode), the handset microphone is disabled, securely muting thetransmission of speech and background sounds while still allowingthe remote party to be heard. PTT handsets are ideal for suchapplications as conference calls, financial trading, and militaryapplications.Algo PTM handsets work in just the opposite way as PTT - bydisabling the handset microphone when the button is pressedand restoring normal operation when the button is released.PTM handsets are suited for applications where only periodic muting of conversations is required.Ordering GuideNortel Digital & Internet TelephonesT7000/M3900/i2000 SeriesColor PTT PTMPlatinum 1074-66 1073-66Charcoal 1074-70 1073-70Ether Grey 1074-74 1073-74Nortel IP Phones (1100 Series)Charcoal 1097-70 1096-70Nortel Digital Telephones M2000/M7000 SeriesChameleon Grey 1071-35 1070-35Dolphin Grey 1071-93 1070-93Black 1071-03 1070-03Nortel MDC (Meridian Digital Centrex) M500 SeriesChameleon Grey 1079-35 1078-35Black 1079-03 1078-03T7000, M3900, i2000-Series; M2000,M7000-Series; Nortel MDC; IP Phone1100-SeriesNew for 2008:1097-70 PTT Handset and1096-70 PTM Handset forNortel IP Phone 1100 Series(Contact Algo for order leadtimes)Algo Communication Products Ltd. 59 www.algosolutions.com1-877-884-2546 (USA & Canada) (604) 454-3790
