    be routed differently than the overall area 
    code. 
    l Enter the specific office codes that are to 
    be routed differently. 
    Example 2-m the second example, the route 
    plan only applies to office code exceptions. The 
    first office code exception table may be docu- 
    mented on the LCR Plan record sheet: 
    l Check the box on the record sheet next to 
    Office Code Exception Table number. 
    l Enter the number of the exception table 
    (1 - 8). Make sure this table number is not 
    entered on any other plan, or on the con- 
    tinuation sheet. 
    l Enter the applicable area code. 
    l Enter the specific office codes that are to 
    be routed differently than the area code. 
    7.36 Program 53-LCR Schedule Assign- 
    ments: 
    This program assigns up to three time 
    schedules to each plan. Each time schedule con- 
    sists of four different route definition choices (de- 
    fined in 
    Program 54) available to the four station 
    groups (defined in 
    Program 56). It may be helpful 
    to complete 
    Program 54 portions of the plans and 
    Program 56 before proceeding. 
    Typical Installation without time scheduling 
    feature-In 
    most cases, an installation will not 
    require use of the time schedule feature. To reflect 
    this on the record sheets for plans 1 - 8: 
    1: Enter the same Schedule Start Times for 
    Schedules 1 and 2. Use military time, in the 
    format HH:MM (Hours:Minutes). Fill in all four 
    digits. Initialized data assigns “0000” to all 
    times. 
    l If LCR software sees schedules 1 and 2 
    have the same start times, then it only 
    looks at schedule 1 for route definitions. 
    2: Enter 
    Route Definition Numbers for Sched- 
    ules 1 
    and 2. Four definitions may be entered 
    for each group. 
    l LCR Station (Class) Groups 1 - 4 are 
    assigned in 
    Program 56. 
    l LCR Route Definition numbers I- 4 are 
    defined in 
    Program 54. 
    l The order in which the route definitions are 
    entered defines the order of LCR line se- 
    lection. The most desirable route should 
    be entered in the leftmost position, and the 
    least desirable route in the rightmost posi- 
    tion. 
    l If “1” is assigned to Station Group 1, and 1 
    for route definition only, then those as- 
    signed will only be able to use route defini- 
    tion 1, thereby restricting them during times 
    that route definition 1 is not allowed. 
    l Keep in mind that the route definition num- 
    ber is being entered, not the CO line group 
    number. The definitions are assigned in 
    Program 54. 
    Installation requiring timeschedulingfeature- 
    When an installation requires the time scheduling 
    feature to be programmed, three “shifts” of route 
    definitions can be assigned per station group. To 
    reflect this on the record sheet, substitute step 1 of 
    the procedure described for the typical customer 
    with the following: 
    1: Enter the Schedule Start Times for Sched- 
    ules 1,2 
    and 3. Use military time, in the format 
    HH:MM (Hours:Minutes). Fill in all four digits. 
    Initialized data assigns “0000” to all times. 
    l Start time for schedule 2 is the stop time for 
    schedule 1. 
    l Start time for schedule 3 is the stop time for 
    schedule 2. 
    l Start time for schedule 1 is the stop time for 
    schedule 3. 
    7.37 Program 54-LCR Route Definition: The 
    purpose of this program is to define four different 
    ways of routing calls for each of the eight LCR 
    plans. Define each route by selecting and entering: 
    1: CO Line Group (1 - 8): Refer to the LCR CO 
    Line Programming Reference Table completed 
    at the beginning of the LCR record sheets. 
    l Each CO line group represents a type of 
    service, e.g., special common carrier, for- 
    eign exchange, local line group, etc. 
    l Program 16 assigns CO lines to CO line 
    groups 1 - 8 (81 ‘- 88). 
    l Program 40 denies incoming and outgo- 
    2-31  
    						
    							PROGRAMMINGPROCEDURES-INSTRUCTIONS/SYSTEMRECORDS 
    SECTION 200-096-302 
    FEBRUARY1991 
    ing CO line access to stations, including 
    LCR access. 
    l Program 41 allows CO line access to sta- 
    tions using LCR only for outgoing calls 
    when enabled. 
    2: Modified Digits Table (1 W 6): Refer to Pro- 
    grams 
    55-0, 55-l and 55-2. The system 
    handles CO line groups differently, according 
    to which modified digits table was assigned in 
    Program 54. 
    7.40 Program 55 Series-LCR Modified Digits 
    Tables 
    7.41 
    This program defines six modified digits tables 
    for LCR call handling. Each modified digits table 
    assigns editing steps that include: 
    l Deleting a pre-defined quantity of digits from 
    the front of the number dialed 
    (Program 55-O). 
    l Adding a pre-defined number to the front of the 
    number dialed 
    (Program 55-l). 
    l Adding a pre-defined number to the end of the 
    number dialed 
    (Program 55-2). 
    7.42 The purpose of this program is to define call 
    handling so the route definition used by LCR is 
    invisible to the station user. The station user handles 
    all calls the same way. The goal is for LCR to 
    remember the dialing peculiarities of each call 
    route, so the user doesn’t need to know. 
    7.43 Program 55-O-LCR Modified Digits-De- 
    lete: 
    Enter the Quantity of Digits that should be 
    deleted from the front of the numberdialedfor each 
    of the six 
    Table Numbers in the Delete Digits 
    Table. 
    The maximum number is ten. Always make 
    the entry two digits. 
    7.44 Program 55-l -LCR Modified Digits-Add 
    to Front of Dialed Number: 
    Enter the digits that 
    must be added to the front of the number dialed in 
    the 
    Add Digits Table. The maximum quantity of 
    digits is 22, including pauses. 
    l Length of pause can be indicated by using 
    codes (Pl N P8) specified in the 
    Pause Entry 
    ReferenceTable. 
    Each pause takes ttio digits 
    of memory space. 
    l Try to allow for the longest wait, e.g., make the 
    pause longer, rather than shorter, to accom- 
    modate the length of time a carrier may need to 
    access the service tones, etc. 
    7.45 Program 55-2-LCR Modified Digits-Add 
    to End of Dialed Number: 
    Enter the digits that 
    must be added to the end of the number dialed in 
    the 
    Add Digits Table. The maximum quantity of 
    digits is 22, including pauses. 
    l Length of pause can be indicated by using 
    codes (PI N P8) specified in the 
    Pause Entry 
    Reference Table. 
    Each pause takes two digits 
    of memory space. 
    l Try to allow for the longest wait, e.g., make the 
    pause longer, rather than shorter, to accom- 
    modate the length of time a carrier may need to 
    access the service tones, etc. 
    7.46 Program 56-LCR Station Group Assign- 
    ment: 
    The purpose of this program is to assign all 
    defined station ports to one of four LCR Station 
    Groups. 
    l Station groups are completely independent of 
    one another. Therefore, each station group 
    must be defined separately. 
    l Software does not automatically assign the 
    highest, all-inclusive routing priority to class 1 
    stations, making all routes available to class 2, 
    3 and 4 stations available to class 1 as well. 
    l Instead, stations are assigned to independent 
    groups (partitioned). Completely flexible as- 
    signment of routing definitions to groups is 
    allowed, with no one group’s definition affect- 
    ing another’s, Each group’s route definitions 
    are specified to activate separately according 
    to the time schedules set by 
    Program 53. 
    1: 
    Enter the station group number next to the port 
    number.

    STRATADKSOFTWARERELEASES 
    Software Guide: This is a reference guide that provides updated information regarding software enhancenients to 
    the STRATA Digital Key (DK) System. 
    DKSoftware Identification: The DKoperating software is stored on Read Only Memory (ROM) chips and is identified 
    by ROM Version. 
    There are four ROM chips in a DK ROM set, which are installed on a processor control circuit PCB. There are four 
    versions of PCTU: PCTU3 is the 
    Release 3 version; PCTU2 is the Release 2 version and PCTUS is the Release 2 
    version for use with DK24 only; PCTUl is the first released version. PCTUI can be upgraded to PCTU2 by changing 
    PROMS supplied in the Toshiba PURR2 upgrade kit. All PCTUS PCBs, used in STRATA DK24, contain 
    Release 2 
    version software. PCTUI, PCTU2, and PCTUS cannot be upgraded to PCTU3, 
    Release 3. 
    The ROM version may be displayed by running Program 00-O from the local programming telephone or remote 
    programming terminal. The ROM version is also printed on the label attached to each of the four ROM chips in a set. 
    The last two or three characters on the label identify the ROM version: e.g., 2K, 
    lG, etc. as shown below:

    System Record Sheets: The same System Record Sheets are used for a// STRATA DK models and are updated 
    with each DK software release. Each updated and new record sheet will be dated when released and may be inserted 
    in the original document to replace the outdated record sheet (the record sheets released with the original PCA2K 
    software are dated June 1989). 
    On the record sheets, the letters “R2” note options available with 
    Release 2 and above only (see the software guide 
    for the R2 option list). All program options that are not noted with “R2”are available with a//STRATA DK software. The 
    letters “R3” note options available with 
    Release 3 software only (see the software guide for the’R3 option- list). All 
    program options available with “R2” are also available with

    Emergency number override of 
    verified/forced account code 44A (51 - 53) 
    - Allows up to three emergency numbers 
    (911, etc.) to be programmed to bypass 
    the forced (verified or nonverified) account 
    code dialing requirement. 
    Traveling class of service 44B (1 - 4) 
    - This feature allows a toll restriction 
    override code to be assigned to each 
    station class (class 1 - 4). When the toll 
    restriction override code is dialed from a 
    telephone, the telephone will assume the 
    class the code is assigned to until the call is 
    complete. The telephone will return to its 
    normal class when the call is complete. 
    B button 39, Code 50 
    Flexible button, allows voluntary account 
    codes to be entered anytime without 
    interrupting existing conversations. 
    Amplified Conference 
    (External) 10-1, LEDs 01 - 04 
    10-2, LEDs 18 and 19 
    10-3 Allows up to four customer-supplied 
    amplifiers to be connected to selected 
    system PEKU ports. The amplifiers 
    automatically switch into two CO line 
    (Tandem) and two CO line/station 
    conference calls. The amplifiers increase 
    the transmission volume level that is 
    typically degraded because of added 
    telephone network losses during two CO 
    line calls. Two line DISA and TIE line 
    calls are also amplified. 
    Flexible BGM connection 
    12, IO-3 Allows alternate BGM source and 
    external page output connection to any 
    slot with a PEKU or PESU installed.
