    							CHAPTER 1 
    INTRODUCTION 
    1. General 
    1.01 PERCEPTION, and PERCEPTION,, are 
    both stored program-controlled systems which uti- 
    lize a 16-bit microprocessor as the central process- 
    ing unit (CPU). The system memory is made up of 
    Read Only Memory (ROM), Dynamic Random 
    Access Memory (DRAM), and Static Random Ac- 
    cess Memory (SRAM). The small amount of ROM 
    that is provided contains the “Loader” program for 
    the 3.5inch disk drive (NFDU card). When the 
    system is initially powered up or is reset manually, 
    the remainder of the Operating System programs 
    and Customer Data will be loaded into RAM from 
    the disk, under the control of the Loader program. 
    1.02 Since Dynamic RAM is volatile (its contents 
    are lost when power is removed), the disk remains 
    in the system as backup. If a reload is required, the 
    entire system program and customer database will 
    reload in approximately 45 seconds. In Lodging/ 
    Health Care operation, some customer data is 
    stored in Static RAM in order to protect it in case of 
    a power failure. 
    2. Dual Disk Operation 
    I 2.01 PERCEPTION 
    e&ex systems with D.02 soft- 
    ware and above, utilize two floppy disks (FDs) for 
    the storage of operating and maintenance data. 
    One of these disks (the System 
    FD) is used specifi- 
    cally for the system program, customer data, and 
    the DSYS, DTRF, and TPER maintenance pro- 
    grams, while the other disk (the Maintenance FD) 
    is used exclusively for all other maintenance pro- 
    grams. A separate disk drive for each disk is 
    required for remote maintenance. Systems with a 
    single disk drive must interchange disks manually 
    in order to perform the various system program- 
    ming functions. The System FD is inserted for 
    system program loading, data saving, and system 
    operation, while the Maintenance FD is inserted for 
    system programming or the performance of main- 
    tenance operations. Dual-drive systems require 
    PROGRAMMING PROCEDURES 
    SECTION 200-255-301 
    JANUARY 1993 
    the insertion of the System FD in FDDO, followed by 
    the insertion of the Maintenance FD in FDDl. The 
    various steps involved in floppy disk installation for 
    both single- and dual-disk systems are noted in 
    Table l-1. 
    3. Customer Data 
    3.01 All PERCEPTION,,,, options are controlled 
    by entries made in the Customer Database. Tables 
    are provided for defining System Parameters and 
    Trunks, as well as individual station features. The 
    Customer Data is unique to each system and is 
    usually entered by using a keyboard terminal. After 
    the data has been entered into system memory, a 
    simple keyboard command causes it to be copied 
    onto the System FD, where it remains as a perma- 
    nent record. 
    4. Utility Programs 
    4.01 In addition to the Operating System Pro- 
    grams and Customer Data, the System FD also 
    contains many Utility Programs, which are used to 
    program and maintain customer data. The Utility 
    Programs are divided into three main groups: 
    1) Data Input Procedures 
    2) Data Output Procedures 
    3) Maintenance Procedures 
    4.02 When required, a Utility Program can be 
    called up by entering a command via the keyboard 
    terminal. The system will respond by locating the 
    proper Utility Program on the proper floppy disk and 
    then loading it into the memory overlay area. When 
    the loading is completed, a prompt will be output to 
    the terminal. The overlay area can accommodate 
    only one Utility Program at a time. When a program 
    is called up, the previous program will be taken out 
    of the overlay. 
    NOTE: 
    Any disk failure will cause an error code to be 
    output to the terminal. See Table 19-6 for the 
    list of error codes.

    NOTES: 
    1. If the System-FD is not inserted in FdDO, LEDs 1 - 4 on the LCCU will light. 
    2. The DSYS, DTRF, and TPER Programs are stored on the System-FD. If this disk is not inserted 
    in FDDO, then the system will respond with the following message: 
    “CURRENT FD IS NOT SYSTEM FD. 
    CHANGE IT TO SYSTEM FD.” 
    3. If the Maintenance-FD is not installed either in FDDO of a one-drive system, or in FDDl of a two- 
    drive system, then the following message will be generated: 
    “CURRENT FD IS NOT MAINT. FD. CHANGE IT TO MAINT. FD. ” 
    4. If the System-FD is not installed in FDDO, then the system will request a change by generating the 
    same message as in note 2. 
    5. In single drive systems, the Maintenance FD can be left in FDDO up untilperforming a SAVE. Before 
    a SAVE can actually be performed, the System FD must be installed. 
    6. After an initialization, to clear Call Forwarding (CFD) and Message Waiting (MSG) data, is 
    performed on the system, perform the following procedures: 
    a. Run the DMYC Program. 
    b. When it is completed, perform the following steps at the attendant console: 
    : ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    l Wait about 20 min& for the system to run ihrough and clear the above data. 
    l Initialize the system. 
    l Do a data dump (DDMP) procedure. 
    l Reload the system (power off and on).

    SET UP KEYBOARD/REMOTE 
    MAINTENANCE 
    1. Keyboard Terminal 
    1 .Ol 
    PERCEPTION, and PERCEPTION,, 
    systems are designed to interface with a standard 
    asynchronous keyboard/printer data terminal (a 
    Texas instruments Model 743or745, or equivalent) 
    or a personal computer configured as a dumb 
    terminal. The terminal is connected to the system 
    via a female-type RS-232C connector (labeled 
    TTY), which is located on the connector panel on 
    the lower rear of the basic cabinet. The TTY port 
    can operate at a speed of either 300 or 1200 bps, 
    which is designated by a switch on the front of the 
    LCCU PCB. The selected bps setting must match 
    the setting on the connected modem or TTY. TTY 
    and modem port pin assignments for 
    PERCEPTlONe systems are shown in Table 2-1, 
    while assignments for PERCEPTlONe, systems 
    are shown in Table 2-2. 
    2. Remote Administration 
    2.01 PERCEPTlONe and PERCEPTIONex SYS- 
    terns can be programmed and tested from a re- 
    mote location via a locally-provided 300 or 1200 
    bps modem. Utility Programs can be called up via 
    a telephone line and then the desired data change 
    or test can be performed. On the PERCEPTION,, 
    the modem connects to the TTY RS-232C connec- 
    tor on the rear of the basic cabinet via a Null 
    Modem cable (see Table 2-1 for PERCEPTlONe 
    pin assignments). On the PERCEPTIONex, the 
    modem connects directly to the modem connector 
    on the rear of the basic cabinet (see Table 2-2 for 
    PERCEPTIONex pin assignments).

    3. Data Format 
    3.01 
    The PERCEPTION, and PERCEPTION,, 
    systems communicate on the TTY and modem 
    ports via the standard 7-bit ASCII code, using one 
    start bit, one stop bit, and one parity bit. Both 
    systems transmit even parity and ignore parity on 
    the receive side. 
    3.02 Prior to switching on the PERCEPTfONe or 
    PERCEPTION,, system, data terminal, ormodem 
    power, all speed settings should be made and data 
    terminals and modems should be set for full duplex 
    operation.
