    General 
    A system (Figure 15) consists of a key ser- 
    vice unit (Vie HKSU is shown), power supply, up 
    to 16 stations*, HOLB, HSMB and HOXB op- 
    tional modules, and a maximum of six door 
    phones, The door phone control unit(s) (HDCB) 
    occupy one or two station location(s). All connec- 
    rinrs ber\/lleen the key service unit and the tele- 
    phones are made via a customer-provided main 
    distribution frame. Using modular line cord(s), 
    the CO lines are then connected between the 
    -left side panel and the locally provided RJ-25C 
    (up to two each) or RJ-11C (up to six each) 
    jacks. An external tuner (or equivalent) is re- 
    quired if the Music-On-Hold/Background Music 
    feature is utilized. 
    *Some optional features reduce maximum 
    station capacities (see Optional Features). 
    A functional block diagram of both key ser- 
    vice units is shown in Figure 16. It consists of 
    CO and station interfaces on the main PCB, in- 
    cluding a solid-state, space-division matrix and 
    the central control equipment (SCCU/VCCU). Op- tional interfacing equipment includes additional 
    station connections (SSTU), off-hook call an- 
    nounce (SVCU), remote maintenance (SDTU), off- 
    premises line (HOLB), station message detail 
    record (HSMB/STMU*), lA2 interface (HCNB), 
    auxiliary device interface (HIOB), door phone con- 
    troller (HDCB) and door phone/monitor station, 
    external page amplifier (SEPU), internal music- 
    on-hold source (SMOU), and power failure 
    (SPFU”) PCBs are a!so shov.n. 
    “STRA TA Se only 
    The system is entirely under the control of 
    a single-chip microprocessor, located (along 
    with the system program and data memories) on 
    the VCCU/SCCU PCB (STRATA Vie/Se, respec- 
    tively), which mounts on the VMAU/SMAU, re- 
    spectively. 
    Connections between the station voice lines 
    and the CO lines are via the switching matrix 
    provided on the VMAULSMAU PCB (STRATA 
    We/Se, respectively). The VMAUSMAU also 
    provides a similar matrix for intercom connec- 
    tion, background music, paging connections and 
    the distribution of various system tones (dial, 
    busy, etc.).

    network or PBX for up to two lines 
    (STRATA Se) or up to three lines (STRATA 
    Vie). Ring detection, hold and dial outpuls- 
    ing for these lines are performed by this 
    board. Depending upon local CO require- 
    ments, each incoming line can be sepa- 
    rately connected and programmed to pro- 
    vide DTMF or rotary-dial outpulsing. 
    c) Tone: Performs a number of miscellane- 
    ous system functions: 
    l Generates system tones. 
    , 
    l Provides the switching matrix for the de- 
    livery of tones for both paging and inter- 
    com connections.

    performed by the single-chip microprocessor 
    on this printed circuit board. The system pro- 
    gram stored in ROM, RAM for system opera- 
    tions, and the RAM for system data storage 
    are also located on this circuit board. A bat- 
    tery on this board protects system memory 
    should a power failure occur. 
    SCOUNCOU: An optional interface between 
    the SMAWVMAU and one/three additional 
    CO line(s). Depending upon local CO require- 
    ments, the SCOU/VCOU is programmed to

    provide DTMF or rotary-dial outpulsing. The 
    SCOU serves one CO line; the VCOU serves 
    up to three CO lines, and both serve up to 
    three off-premises lines. 
    SSTU: An optional interface between the key 
    service unit and stations 18 - 25 (stations 14 
    - 17 on STRATA Se). Each SSTU PCB serves 
    up to four stations. Two-pair wiring is re- 
    quired for each station; one pair carrying vo- 
    ice and the other pair carrying control data to 
    and from the station. 
    SMOU: An optronal music-on-hold source that 
    provides electronic synthesized music. A 
    choice of two musical tunes are available, se- 
    lected via a switch on this board. The SMOU 
    is connected to the SMAWVMAU via an 
    8-pin connector. 
    SEPU: An optional 3-watt amplifier for external 
    paging, using a customer-supplied 8-ohm 
    speaker (connected to the SMAWVMAU via 
    a 1 O-pin connector). 
    SVCU: The Off-Hook Call Announce interface 
    that mounts on the main printed circuit board 
    of the key service unit to provide OCA access. 
    One SVCU is required for every eight stations 
    requiring OCA. (Adds two intercom lines if 
    STRATA We.)  
    						
    							/. 
    SDTU: Provides Remote Administration/Main- 
    tenance access via its built-in 300/l 200 
    baud modem. One SDTU per system is re- 
    quired for Remote Administration/Mainten- 
    ance. 
    STMU: Required for connection to an HSMB to 
    provide SMDR for a STRATA Se key service 
    unit. 
    HPSU 6120/7120: Each system’s required 
    voltages are provided by one of these factory- 
    installed power supplies. The HPSU connects 
    to a standard 3-wire, 117 VAC, 60-Hz, 
    grounded wall outlet, with a permissible AC 
    input voltage range of 90 - 130 VAC. 
    HPFB: An opticnal batter!/ backuo unit that is 
    available for the HPSU 6120 (STRATA Se). 
    With the optional battery backup assembly in- 
    stalled, all functions of the system will con- 
    tinue to operate for approximately two to 
    three hours after a loss of normal electrical 
    power. Calls will not be disconnected during 
    switch-over to or from battery power. 
    HPBU-7: An optional battery backup unit for 
    the HPSU 7120 (STRATA Vie). It is a printed 
    circuit board that mounts inside the power 
    supply housing and is connected to the recom- 
    mended battery pack (which is customer- 
    supplied, consisting of two 12 VDC, main- 
    tenance-free, automobile-type 
    batteries-80 
    amp/hour maximum rating). With the op- 
    tional battery backup assembly installed, all 
    functions of the system will continue to oper- 
    ate 
    for several hours (the actual time period 
    is in direct ratio to the type and size of bat- 
    teries seiected) after a ioss of normai electri- 
    cal power. Calls will not be disconnected dur- 
    ing switch-over to or from battery power. The 
    HPBU-7 also provides a charge to the battery 
    s 
    pack during normal operations. 
    Option Modules 
    HOLB: An off-premises line module that allows 
    the bridging of a CO line, which appears in 
    the system with a conventional telephone; su- 
    pervision is provided. Each HOLB provides 
    three circuits, all three of which may be di- 
    rected to an answering machine (or similar de- 
    vice) attached to the HUNT connector.

    on STRATA Se) that allows up to three (each 
    HDCB) door phone/monitor stations (MDFBs) 
    to ring pre-selected stations. The HDCB has 
    three outputs (A, 6, C), which are modular con- 
    nectors for the three MDFBs. (Outputs B and 
    C on either/both HDCB(s) may be used for 
    the Door Lock and Alarm features, respec- 
    tively.) 
    HOXB: An external module .that serves as an 
    interface between the key service unit and 
    conventional, standard telephones or off- 
    premises extension (OPX) lines. Each HOXB 
    PCB serves two extensions; one HOXB per 
    system. An HOXB will operate with either 
    DTMF or rotary-dial telephones. An auxiliary 
    ring generator/power supply (MRGU) is re- 
    quired for use with the HOXB. 
    HSMB: Serves as an interface between the key 
    service unit and a printer or storage device 
    used for the SMDR feature. The module is 
    equipped with an RS-232C interface and con- 
    nects to the left side panel via one supplied 
    8-wire 
    modular connectors (one HSMB per 
    system). (Se also requires an STMU PCB.) 
    HCNB: Provides an interface between a lA2 
    key system 
    and the CO lines appearing 
    therein to a STRATAe system. One HCNB is 
    required for every three lines where dual ap- 
    pearances are desired. Also, A-lead control, 
    lamp signal detection and dial outpulsing are 
    performed by this module (see Figure 19).

    HIOB: Provides one circuit to interface with ex- 
    ternal devices such as a voice mail port, an- 
    swering machine, standard telephone, mo- 
    dem, etc. Up to eight HlOBs (four on a 
    STRATA Se) may be installed on a system. 
    Each HI06 is connected to a proprietary sta- 
    tion port, reducing station capacity accord- 
    ingly. 
    Station Equipment 
    The principal components of the electronic 
    telephone are: handset, dial pad, speaker, micro- 
    phone, two volume controls, four fixed feature 
    buttons, an m button, and 9 or 19 flexible CO/ 
    feature buttons. LED indicators are provided for 
    all buttons except for m and m. See Fig- 
    ures 10 and 12. 
    The single-line electronic telephone (Figure 
    9) is equipped with three permanently dedicated 
    buttons (mm=) and an Intercom/CO 
    line button, which is not labeled. 
    The lo-button Busy Lamp Field electronic 
    telephone (Figure 11) with speakerphone pro- 
    vides 10 buttons that can be assigned to control 
    intercom, CO line and feature operation, plus an 
    LED indication of which stations are in use. 
    A 20-button Liquid Crystal Display elec- 
    tronic telephone (Figure 13) with speakerphone 
    may be located at any or all of the stations. The 
    32-character alphanumeric display provides 
    many capabilities- an accurate clock/calendar 
    in its idle state; and elapsed time, dialed 
    number, calling station and CO line are just a 
    few of the features available. For additional ex- 
    planations of the features listed below, see Liq- 
    uid Crystal Display.

    l Timed Reminders 
    All phones are easily converted for wall 
    mounting, feature modular handset cords, are 
    equipped with a second modular connector for 
    headset connection (except the single-line), and 
    are connected to the system via modular line 
    cords. 
    -14- 
    An optional replacement base for the elec- 
    tronic telephone provides a built-in 300/1200 
    baud modem with automatic answering capabil- 
    ities. It is a Bell Standard, full duplex modem. 
    The optional door phone/monitor station 
    (Figure 6) allows distinctive ringing to pre- 
    selected station(s). When a station dials an indi- 
    vidual door phone, a circuit providing monitoring 
    capabilities on the intercom, is established. This 
    option requires station 13 and/or 14 (station 1 1 
    and/or 12 in STRATA Se) to be replaced by a 
    door phone control unit (HDCB) and up to six 
    door phone units (MDFBs)-three each HDCB. 
    One door phone/monitor (only station 13C for 
    Vle; 11 C for Se) can be replaced by an alarm 
    control circuit on station 13 HDCB and one by 
    a door lock control circuit on all HDCBs. 
    An external amplified speaker (HESB) may 
    be connected in any one of the following three 
    applications: 
    l Loud Ringing Bell: Allows you to amplify 
    the tone of a paging/ringing signal without 
    using other manufacturers’ equipment. The 
    signal can be amplified on all 6000-series 
    phones, except the single-line electronic tele- 
    phone. Three-pair wiring is required for this 
    application. 
    l Amplified Speaker: Allows you to use the 
    HESB as a paging speaker, reducing the 
    need for other manufacturers’ paging equip: 
    ment. 
    l Talkback Amplified Speaker: Allows you to 
    provide a talkback speaker in areas where a 
    telephone is not needed. For talkback opera- 
    tion, connect the HESB to the door phone 
    unit (MDFB), which is used as a microphone; 
    however, the push-button is inoperative. 
    The HESB is a 6” 3-watt speaker with an 
    amplifier that is built into an attractive speaker 
    box (Figure 8). A +12 VDC power supply 
    (HACU-120), which connects to the back panel 
    via an 8’ cord, is included with each HESB. 
    Installation 
    The key service unit is configured for wall 
    mounting only. 
    All external devices are connected to the 
    key service unit via connectors and terminals on 
    the side panels, as follows: 
    a) CO lines are connected to the key service 
    unit right side panel via separate (one for  
    						
    							each line) single-pair modular cords or a 
    single 3-pair modular cord (STRATA Se); or 
    two 3-pair or six single-pair modular cords 
    (STRATA Vie). 
    b) The station connection points are extended 
    from the key service unit to the main distri- 
    bution frame using 3-pair modular line cords. 
    The individual telephones are connected to 
    the main distribution frame using 3-pair sta- 
    tion cables. 
    c) A screw-terminal barrier strip is mounted on 
    the left-hand side of the key service unit to 
    provide attachment points for the music-on- 
    hold source input, relay service (STRATA Vle 
    only) and external page output. 
    d) Two (only one for STRATA Se) modular con- 
    nectors are also provided on the left side 
    panel for two (only one for STRATA Se) op- 
    tional off-premises line modules (HOLBs). 
    The power supply is mounted inside the key 
    service unit. In STRATA Se a connector is pro- 
    vided on the left side panel for optional system 
    reserve power (HPFB). In STRATA Vle an op- 
    tional battery backup printed circuit board is 
    available for the power supply. 
    Maintenance 
    Faults in the system are repaired by replac- 
    ing any faulty component (printed circuit board, 
    subassembly, telephone, etc.) and returning it to 
    the manufacturer for repair. 
    In addition, remote administration/ 
    maintena-rice allows the system to interface via 
    an SDTU (built-in modem) with a remote loca- 
    tion. This reduces the cost of routine data base 
    changes by eiiminaring the need of a technician 
    to be ?n-site for each software change.

    Alternate Point Answer: CO or intercom calls 
    can be answered from any station. 
    Automatic Dialing-System: Allows up to 4C 
    numbers to be stored in the system memory. 
    After selecting an outgoing line, any station 
    user can cause one of the.‘stored numbers to 
    be outpulsed by dialing the proper access 
    code. 
    Automatic Hold Recall: A CO line placed on 
    hold by any station will recall that station af- 
    ter a programmable period of time. A different 
    time period can be selected fo: each station. 
    Automatic Release from Hold: The system au- 
    tomatically releases held CO lines if a discon- 
    nect signal is r,eceived from the Central Of- 
    fice. 
    CO Line Pickup Groups: In STRATA Vle only, 
    using a dial code or the m button, allows 
    CO line pickup from another station. Two Call 
    Pickup Groups can be defined in program- 
    ming and buttons (m and m) can be as- 
    signed to phones for each group. 
    Conference (Multi-CO Line): The system will 
    conference two CO lines and up to three sta- 
    tions. See Amplified Conference. 
    Conference(Multi-Station): Non-amplifiedcon- 
    ferencing is permitted to a maximum of four 
    stations and one CO line. See Amplified Con- 
    ference. 
    CTX/PBX Compatible: System features, such 
    as Toll Restriction and Automatic Dialing, are 
    compatible with CTX/PBX operation. 
    CTX Ringing Repeat: To facilitate the use of 
    special calling/callback features on CO/CTX/ 
    PBX lines, the system will ring the called sta- 
    tion with the same on/off cadence that is re- 
    ceived from the outside line. 
    Delayed Ring,ing: A 12- and/or 24-second ring 
    delay may be programmed for each station to 
    permit alternate answering. The delayed ring 
    is provided for each line selectively by each 
    station. 
    Distinctive Ringing: CO and intercom calls are 
    distinguished by different ringing tones.

    basis as determined by system programming. 
    External Page Interface: A 600-ohm connec- 
    tion point is provided for a customer-provided 
    external amplifier/speaker. An SEPU PCB 
    (see External Amplified Speaker and External 
    Page Amplifier) is mounted in the key service 
    unit when a customer-provided external 
    speaker only is used; the output impedance 
    is 8 ohms. This page circuit can be accessed 
    as part of the All Call Voice Page feature. 
    F!exible Intercom Numbering: A station inter- 
    com number can be flexibly programmed up 
    to any 4-digit number. It is, therefore, possible 
    to match a station’s intercom and CTX line ex- 
    tension number. 
    Flexible Key Assignment: Allows each phone 
    to be programmed for the optimum use of its 
    CO or feature buttons. 
    Flexible Line Ringing Assignment: A program- 
    mable ring or no ring option is provided for 
    each line selectively by each station. 
    Forced Account Code: Requires selected sta- 
    tion(s) to dial an account code prior to dialing 
    a number. The account code is recorded with 
    call details on the SMDR report. 
    Group Paging: Special 2-digit access codes 
    (81, 82, 83 or 84) permit voice paging to one 
    of four zones. Zone assignment is via $oft- 
    ware and is totally flexible. Paging is via the 
    speakers of idle telephones. 
    Least Cost Routing: Enables the customer to 
    decide over which trunks outgoing voice and 
    data calls will be routed. This can greatly re- 
    duce the cost of long distance calling. Four 
    classes of LCR can be programmed to give 
    priority routes to .the users who need them. 
    (STRATA Vle only.) 
    Live System Programming: Live system pro- 
    gramming is accomplished without service in- 
    terruption to other station users by placing 
    the system in the special programming mode 
    and inputting 
    data via station 17 (station 13 
    in STRATA Se). Station 17(13) is the only sta- 
    tion that is “down” during programming. 
    -16- Message Waiting: Any station (including the 
    designated Message Center) can set a Mes- 
    sage Waiting LED at any station with the Mes- 
    sage Waiting LED of that station. The called 
    station cancels the LED by lifting the handset 
    and depressing the m button (not avail- 
    able on single-line electronic telephone). See 
    Flash Button. 
    MF Signal Time (160/80 ms): The standard 
    MF dial signal time is 80 milliseconds, but it 
    may be extended to 160 milliseconds, if re- 
    quired by the Central Office or to activate re- 
    mote equipment. 
    Multiple Simultaneous Handsfree Intercom 
    Paths: Two intercom paths are standard in 
    the systems. Both intercom lines are able to 
    carry handsfree conversations simultane- 
    ously. (STRATA Vle may be increased to four 
    paths optionally.) 
    Music-On-Hold Interface: An interface is in- 
    cluded for a customer-provided music source. 
    CO lines placed on hold will be connected to 
    this source. In addition, this music may also 
    be broadcast from electronic telephone speak- 
    ers and external page when the background 
    music programming options are selected. 
    Night Ringing Answer Code: A night ringing 
    call may be answered from any station via a. 
    dial code. 
    Night Ringing Over External Page: As a prd- 
    grammable option, while the night mode is ac- 
    tive, a system-generated ring tone will be 
    transmitted via the external speaker when- 
    ever any line rings (STRATA We only). 
    Night Transfer: On a programmable optional ba- 
    sis, the system can function with two or three 
    ringing patterns. If three patterns are se- 
    lected, they are designated DAY, DAY 2, and 
    NIGHT. If the two-pattern mode is selected, 
    DAY and NIGHT designations are used. In 
    both cases, the ringing modes are selected 
    with the 
    q button on station 10. 
    Non-blocking Dialing: Dialing is permitted on 
    intercom and all CO lines simultaneously. 
    Outgoing Call Restriction: Any station can be 
    selectively restricted from originating calls on 
    any or all CO lines. However, the station may 
    still receive calls on the restricted line(s).
