Section I. GENERAL INFORMATION
1-l. Scope.
This manual describes the Central Site Subsystem (CSS) equipment which is
part of the Washington Area Image Transmission System (ITS-W). The CSS
(figure 1-1) is located at a central site that includes user furnished
communication (COMSEC) security and link equipment. This manual is directed
to personnel who will operate and monitor the CSS equipment. To familiarize
the operator with the various modes of operation and operating procedures
described in this manual, the overall ITS-W network is described briefly.
1-2. ITS-W Network.
a. ITS-W is a secure multisubscriber, high-resolution photo facsimile
transmission network. The ITS-W (figure 1-2) is organized as a star network
of up to 60 Remote Terminal Subsystems (RTS's) with the CSS as the hub. The
CSS is a computer-controlled switch whose main function is to automatically
interconnect communication lines between RTS's. The interconnects are made in
response to call requests (telephone dialing) originating at each RTS. The
CSS automatically disconnects communication lines between interconnected RTS's
when they have completed transmissions.
b. The RTS may be colocated with the CSS or remotely located. Remote
locations are interfaced to the CSS via customer furnished COMSEC and
communication link equipment.
1-3. CSS Purpose and Use.
a. The CSS (figure 1-3) is a digital switch controlled by a PDP 11/04
computer and its peripherals. The CSS switch is designed to operate
automatically and unattended from a system program on a floppy disc. When
commanded by the program, the CSS switch will interconnect RTS communication
lines for the purpose of voice and facsimile transmission between RTS's.

b. A data terminal keyboard/printer provides printouts of specific reports
such as power interruptions. During normal system operation the keyboard
portion is locked out by the program preventing unauthorized entires. The
keyboard can be unlocked by entry of a system program password for the purpose
of modifying specific items on the program.
c. A paper tape reader/punch is provided for initial loading of the
computer operating program and for diagnostic purposes.
d.. For remote located RTS's, the CSS switch is interfaced to COMSEC
communication equipment via a COMSEC interface conditioning unit (CICU) for
the purpose of signal level compatibility between units.
e. Central site master timing is distributed to the CSS and COMSEC
equipment by a timing distribution unit. The unit also provides automatic
backup timing if the site master timing is lost.
1-4. Physical Description.
a. Major unit designators of the central site and cabling between units is
shown in figure 1-4. Unit designators are used to define the unit as an end
item; i.e., Unit 2 is the CSS switch cabinet. Designators are also used to
define the location of assemblies within the unit; i.e., 2A1 indicates that
the assembly is in Unit 2 and in equipment rack position Al (in this case Al
is the floppy disc system). Rack positions Al, A2, A3, etc., are assigned by
the manufacture from top to bottom, left to right when viewed from the front
of the equipment rack. The CSS consists of a Data Terminal -
keyboard/printer (Unit 1), CSS switch (Unit 2), a Timing Distribution Unit
4A2 (located in Unit 4), and three COMSEC interface conditioning units (CICU)
(located in Units 5, 6 and 7). The present CSS equipment configuration
accommodates nine RTS's at remote sites and one RTS at the central site. The
CSS may be expanded in the future to accommodate up to a total of 60 RTS's by
the addition of plug-in units at the CSS switch, additional CICU's, and
associated cabling between units.

ventilation blowers in the bottom of each equipment rack with reusable air
filters accessible at the front of the unit. Ac power is routed from the
user's external source through conduit to a filter box in the bottom of the
cabinet. From the box, RED ac power is routed to a contactor/circuit breaker
assembly. The contactor is controlled from a system control panel (A5) on the
front of the CSS switch. AC power is switched manually at the system control
to provide power to two vertical power strips that are mounted adjacent to the
equipment rack positions. The power source for all rack equipment is provided
through the power strips. All signal data input and output cables and power
cables are routed through the bottom of the cabinet.

e. The CICU (located in Units 5, 6, and 7) (figure 1-8) is configured for
a standard 19-inch equipment rack. The unit front panel contains a manually
operated circuit breaker and power on indicator. The unit is designed to
interface the CSS switch with the COMSEC equipment and accommodates up to
three full duplex data channels. The.CICU converts CSS switch signal levels
to levels that are compatible with the COMSEC equipment (HN74/KG34).
1-5. FUNCTIONAL OPERATION.
a. Call Setup. The CSS provides RTS-to-RTS connection service by use of a
call setup originating at the RTS's. The call, setup is similar to that
provided by a standard telephone network. The CSS switch is continually
monitoring each RTS communication line. A call is initiated using a telephone
handset and keypad located on an RTS operator's console. The RTS operator
desiring to initiate a data transmission removes the handset from the hook and
receives a dialtone signal indicating that the CSS switch is ready to provide
service. The calling RTS operator enters the connection request (two digit
number of called party) by pushbutton on the telephone keypad. The CSS switch
then determines if the requested party is a valid connection and is not busy.
If the request is valid, the CSS switch rings the called party while providing
ringback to the calling party. If an invalid connection is requested, the CSS
switch signals the calling party so that he will cancel his call. If the
called party answers his telephone, the CSS switch stops the ring and ringback
signals at both ends and interconnects both parties. Both RTS parties may
simultaneously transmit and receive facsimile and voice data through the
switch connection. The CSS switch monitors the calling party line for a
signal indicating that he has completed data transmission and/or reception and
hung up the handset. When this signal is received, the CSS switch disconnects
both parties.

b. Connection Service. The CSS switch provides three types of connection
service between RTS's; full duplex, broadcast and self call. The full duplex
service allows two RTS's to be interconnected for simultaneous transmission
and reception of facsimile and voice data (as described in the previous
paragraph). Broadcast connection service allows an authorized broadcast
initiator RTS to dial a two-digit number and be interconnected to up to 59
RTS's on a broadcast list for simplex transmission of data. Broadcast
facsimile and voice transmission is one way only, from the broadcast initiator
RTS to the RTS's on the broadcast list. The CSS switch provides simultaneous
duplex connection service to two through 30 party pairs and broadcast
connection service to one broadcast initiator party at any one time in the
network. Self call service allows an RTS to dial his own number and be
simplex connected back to himself for facsimile transmission and reception.
This service is used by the RTS's as a diagnostic. The CSS switch provides
simultaneous self call service for each RTS in the network.
c. Program Modifications. The system program (disc) can be modified via
use of the data termnal to configure each RTS for CSS switch connection
services as follows: (See paragraph 2-7 for details on program modifications.)
(1) Individual RTS's are assigned a class mark in one of four levels
(1-4). The class marking enables only the higher class marked RTS's to
initiate connections with equivalent or lower class marked RTS's. The class
mark applies to both full duplex and broadcast connection service.
(2) Ten unique broadcast lists and ten associated broadcast initiator
lists are available for program modification. Up to 60 RTS's can be assigned
to each list. Lists are automatically classed marked by the class mark of the
first RTS assigned to a list.
(3) Status of each RTS can be changed to reflect the RTS in or
out-of-service; installed or not installed in the network.

d. RTS/CSS/RTS Communication. Each RTS continually transmits serial word
frames to the CSS switch (see figure 1-9). Each frame contains an RTS status
word (i.e., RTS identity, call requests, hook status, etc.). The RTS status
word is extracted from the frame by the CSS switch for processing. The CSS
switch also continually transmits a control word (i.e., ring, ringback, busy,
etc.) to each RTS in one of two modes. In a CSS idle format mode (figure
1-9A), an RTS is not interconnected to another RTS by the CSS switch, and the
CSS switch generates its own word frames, identical to RTS word frames, but
containing only the CSS control word. This format is sent to all RTS's not
engaged in a call. In a CSS connected mode (figure 1-9B), an RTS is
interconnected to another RTS by the CSS switch, and the CSS switch injects
the CSS control word in the frames passing between RTS's. This format is sent
to all RTS's who are duplex, broadcast, or self call connected. An RTS
control word generated by the RTS's is used by interconnected RTS's for
automatic control of their facsimile transmitter and receiver equipment. The
RTS data is the voice and facsimile data transmitted by the RTS's.

Section II. THEORY OF OPERATION
2-1. General.
a. This section provides a detailed description of the CSS and RTS
operation, the data information exchanged between the RTS/CSS/RTS, the
sequence of CSS connection services, and an explanation of the operator
programmable functions. This section will be referred to in Section III,
Operation, so that the operator will have a complete understanding of
procedures therein.
b. This section first describes the basic functions of the RTS to relate
equipment and signals with the CSS descriptions.
2-2. Remote Terminal Subsystem Functions.
a. An RTS (figure 2-1) consists of a console containing a digital LASERFAX
transmitter, digital LASERFAX receiver (recorder), and voice control unit
(VCU) with control panel. The transmitter is the terminal device used to scan
documents such as photographs or printed matter and the receiver is the
terminal device used to convert facsimile data to hard copy. The VCU is the
data processor and controller for the RTS and interfaces with the transmitter,
receiver, control panel, and 1.544 Mb/s full duplex data link.
b. The RTS has a telephone handset and a keypad that is used to initially
establish an RTS-to-RTS connection via the CSS. When a connection is
established, facsimile data can be transmitted and received simultaneously
with or without voice data. The VCU accepts digital facsimile data from the
transmitter and analog voice information from the handset. It digitizes the
voice signal and formats these data along with control and digital status
information from the VCU control panel and adds frame synchronization words.
The formatted digital data is transmitted over the data link to the CSS.

c. In a like manner, the VCU receives formatted digital data from the
transmitting RTS via the CSS. The VCU deformats the facsimile data, converts
it to analog, and routes it to the receiver for use in modulating a laser beam
which reproduces the transmitted image on photo-sensitive paper. The digital
voice data is converted to analog by the VCU and routed to the telephone
handset to reproduce the transmitted voice signal. The control signals are
routed to control panel circuits controlling the transmitter and receiver..
Additional information on the RTS is given in the ITS-W Remote Terminal
Operators Manual.
2-3. Central Site Subsystem Operational Configuration.
a. Refer to figure 2-2. The configuration shown accommodates two Remote
Terminal lines for explanation purposes. The data format shown at the bottom
of the figure is the frame format used for all data between the RTS/CSS/RTS.
Data is serially transmitted at 1.544 Mb/s in 733 or 734 40-bit word blocks
that include frame synchronization words. The synchronization words are used
to identify the start of a new frame and to maintain synchronization between
RTS/CSS/RTS operations. A detailed description of the data format is given
in paragraph 2-4.
b. The PDP 11/04 provides crosspoint closure control signals to the switch
matrix which interconnect the RTS-to-RTS lines, processes received RTS status
information, and provides control information to be sent to RTS's via the line
control units. The system program is run from the floppy disc system assem-
bly. Operator interface with the computer system is via the data terminal for
system initialization and modification of variables in the program.

c. The line control units (LCU's) are unique for each RTS line and contain
frame synchronizers and formatters/deformatters that synchronize with the data
frames passing between interconnected RTS's and inject CSS switch control
information (formatters) and extract RTS status information (deformatters) to
and from the data frames. If synchronization is lost on the RTS receive line,
the LCU synchronizer provides an EAP (alarm) to the local COMSEC equipment-so
that it can resynchronize with the remote COMSEC equipment.
d. The idle frame format generator creates a serial bit stream format
identical to that of an RTS, except that it contains 733 words per frame. The
idle frame format is routed by the switch matrix to all RTS's which are not
engaged in a call. The idle frame format is designed to look like an inactive
terminal.
e. Continuous 1.544 Mb/s (clock) data streams containing the word frames
are transmitted by the RTS's to the receive side of their respective LCU's.
The LCU synchronizes with the incoming data frames and deformats the word of
the frame containing the RTS status information. This information is then
routed to the processor. The original data stream is not altered in any way
by the LCU, and is routed to the switch matrix for possible interconnection to
other LCU lines for transmission/reception between RTS's. The data format is
designed so that RTS's can communicate directly without CSS switch
intervention (i.e., manually patched around the CSS switch). If no
interconnection has been commanded by the processor, the data stream is
appropriately terminated at the switch matrix. The transmit side of the LCU
synchronizes to the data stream from the switch (either idle format or
connected RTS format) and places control information from the processor in
word two of the format.
f. The CICU units at both the CSS and RTS provide level conversion
necessary for all data, clock and control signals to interface the COMSEC
equipment to CSS switch or the RTS console equipment. The CICU also provides
a reclock function to properly phase the serial data stream to the timing of
the COMSEC equipment.

2-4. RTS/CSS/RTS Information Exchange.
The data format exchanged between RTS's is shown in figure 2-3.
a. Signal Data from Remotes.
(1) Address Request. The Address Request signal received into the CSS
switch is two digits. The CSS switch recognizes and services the input
addresses defined as follows:
Address Numbers
Usage
00 through 09
Invalid Addresses
10 through 69
Remote Terminal Addresses
70 through
79
Invalid Addresses
80 through
89
Network Broadcast List Addresses
90 through
99
Invalid Addresses
Any remote that requests an invalid address or an unimplemented address is
sent an invalid number signal tone.
(2) Receiver Status. Receiver Status signal indicates to the CSS
switch that the RTS receiver is either available, out-of-service or busy.
(3) Transmit Facsimile. The Transmit Facsimile signal indicates to
the connected RTS that the RTS transmitter is presently busy (off-hook) or the
transmitter has completed transmissions and shutdown (on-hook).
(4) RT Call. The RT (Remote Terminal) Call is a request signal to the
connected RTS or RTS's to issue an audible ring. If parties are broadcast
connected, only the broadcast initiator can ring the broadcast list parties.
(5) Hook Status. The Hook Status signal indicates to the CSS switch
that the RTS is requesting service or termination of service.

3-4. Operator General Instructions for Normal System Operation.
a. Operator Interface. The operator interfaces with the system computer
via the LA36 data terminal keyboard/printer. Through use of the keyboard, the
operator loads and initializes the system program. The operator also has the
capability to modify specific items in the system program. The program
automatically prints out failure reports and other statements as described in
following paragraphs.
. b. Startup Sequence. The operator startup sequence is to first power up
the system, then load and initialize the program. Separate procedures are
given for each. Once the system is initialized and the program is running, no
operator action is required for normal system operation other than a monitor
function.
c. AC Power Failure Reports. Should an ac power failure occur at the CS.S
switch, the CSS switch automatically sequences to print out the ac power
failure as "PF" after power is restored. This report is described in
paragraph 2-8, and cause and effect is described in table 3-7 (CSS Operator
Messages).
d. DC Power Failure Reports. Should either a 5 volt or 12 volt-power
failure occur at the CSS switch, the CSS switch prints out the power failure
as "5 VOLT SUPPLY FAILURE" or "12 VOLT SUPPLY FAILURE", as appropriate. This
report is described in paragraph 2-8, and cause and effect is described in
table 3-7.
e. Program Failure Reports. Should a program failure occur during the
system initialization process, the CSS switch will print out the appropriate
failure as follows:
STDB NOT FOUND - ABORT
STDB READ ERROR - ABORT
DDS INTERFACE FAILING
NO PROTECT ALLOWED ON PFAIL

3-22
 Approved For Release 2000/08/04: CIA-RDP80B00829A000800020001-8
The cause and effect of these reports are given in table 3-7.
f. Program HALT.
To prevent interruption of the network, DO NOT move
the computer CONT/HALT switch to the HALT position
during normal system operation.
Should the system program automatically HALT during normal system
operation (computer RUN indicator extinguishes), consult: site maintenance
personnel, or if authorized, move the computer CONT/HALT switch to HALT and
back to CONT. The computer will automatically sequence to continue the
program.
2. Other Monitor Functions. The operator may be required to monitor the
timing distribution unit (4A2). If normal system timing (station clock) is
lost and not automatically restored (within a certain period of time), an
audible alarm will be heard at the site. The timing distribution unit will
automatically switch to the internal clock (INTERNAL CLOCK SELECTED indicator
lights). When the station clock is restored (STATION CLOCK indicator lights),
press the RESET button to reset the internal clock.
3-5. System Power Startup Procedure.
The following procedure assumes that all COMSEC and link subsystem
equipment is turned on and operating, and source power is available to the CSS.
a. Set all three CICU power switches to ON position. Verify that POWER
indicators light.

b. Set timing distribution unit (4A2) POWER switch to ON position. Verify
that STATION CLOCK and INTERNAL CLOCK indicators light. If INTERNAL CLOCK
SELECTED INDICATOR is lit, press RESET button to extinguish.
c. Set CSS switch main power 30 AMP circuit breaker (rear of unit 2,
figure 1-6) to ON position. Verify that cabinet blowers are operating.
d. On the system control unit (2A5), verify that AC INPUT indicator is
lit. Set power switch to ON position. Verify that POWER ON indicator lights.
e. Set dc power supply (2A4) power switch to on (up) position. Verify
that power indicator lights. Verify that voltage indicators read
(left-to-right) 11.5 to 12.5 V, 4.75 to 5.25 V, 14.25 to 15.75 V.
f. Set computer (2A3) power switch to DC ON position. Verify DC ON
indicator lights and cooling fan is operating.
To place LA36 Data Terminal (unit 1) on-line:
(1) Load paper (LA36 Users Manual).
(2) Set LINE/LOC switch to LOC.
(3) Set POWER ON/OFF switch to ON.
(4) Select HDX (half-duplex) on FDX/HDX switch.
(5) Select BAUD RATE 300 switch.

(2) The system program is initialized and running. The computer RUN
indicator is illuminated and the terminal keyboard is locked. No further
entries are required to operate the system. For any modification to the
static data base refer to paragraph 3-7.
(3) Close the CSS switch cabinet doors.
3-7. Operator General Instructions for Modifying the System Static Data Base.
a. Access. The operator can access the data base to perform modifications
after the system is initialized and running and the proper password for the
ITS-W SYSTEM SOFTWARE disc is entered on the keyboard.
b. Data Base Items. Seven data base items (called menu selections) can. be
modified and include:
Menu Selection No. Program Function
(1) Changing elapsed time of timers Ti and T2.
(2) Assigning or changing remote terminal
class marks.
(3) Placing individual remote terminals or
the CSS switch in or out-of-service.
(4) Installing or removing remote terminals
from the network.
(5) Building or modifying broadcast lists.
(6) Building or modifying broadcast
initiator's lists.
(7) Changing the system program password for
access to the static data base.
These programmable data base items are described in detail in paragraph 2-7
and also summarized in the data base modification procedures in paragraph 3-8.

c. Writing Modifications on Disc. When the data base has been accessed,
the system program on disc is transferring into core memory. The operator
modifies items as required, then writes the modifications on the disc by
typing in a single character, 8 (this is a menu selection). This also locks
the keyboard, and the data base cannot be accessed without reentering the
proper password. Modifications written into the disc in use will make it
different from duplicate discs in storage. For duplication of discs, see
paragraph 3-9.
d. Prompt Statements. Prompt statements are printed out by the program
for each menu selection during the modification process of the selection. The
prompt statements require that the operator perform an action.. The statement
related to menu selections is given below. Cause and effect of each statement
is given in table 3-7.

e. Operator General Sequence.
(1) The operator first enters (by keyboard) the proper password
related to the disc. The keyboard is unlocked, and a prompt statement ENTER
MENU SELECTION NO., NULL = DIRECTORY ASSISTANCE is printed out (see table 3-7).
3-27

 Approved For Release 2000/08/04: CIA-RDP80B00829A000800020001-8
(2). The operator enters the menu selection number (entries 1 through
8) by keyboard after the prompt statement ENTER MENU SELECTION NO., NULL =
DIRECTORY ASSISTANCE. If the RETURN key (null) is pressed immediately
following this prompt statement, a numbered menu selection list will be
printed out (Directory Assistance) followed again by the menu select prompt
statement.
(3) After the menu selection number has been entered, the program
responds with other prompt statements (paragraph d. above) requiring that the
operator enter the modifications.
(4) After the' modifications are entered, followed by a carriage return
(RETURN key), the prompt statement ENTER MENU SELECTION NO., NULL = DIRECTORY
ASSISTANCE will be printed out if the modifications are accepted by the.
program. If the prompt statement does not immediately follow operator
modifications., no modifications are entered by the program. (If one modifi-
cation is illegal, all modification entries are illegal and no modifications
are accepted by the program.)
(5) In all cases, except a PASSWORD CHANGE, an illegal entry will
cause the program to respond with the statement ILLEGAL ENTRY followed by a
prompt statement requiring the operator to reenter the modifications. The
operator must reenter valid modifications or the program will loop back to
ILLEGAL ENTRY followed again by the prompt statement requiring the operator to
reenter the modifications. If, after the ILLEGAL ENTRY statement the operator
desires not to enter a modification, the loop can be exited by duplicating an
item that is already written on the data base; i.e., RT 12 is presently class
marked 2. After the ILLEGAL ENTRY statement, class mark RT12 as a 2. This
method can also be used if the operator decides not to make any modifications
after entering a menu selection number (step (3) above).

 Approved For Release 2000/08/04: CIA-RDP80B00829A000800020001-8
(6) Generally, operator entries are declared illegal if the entry is
not a numerical character, not within the range of 1 to 8 for the menu selec-
tion, or not within the range specified for the modification. Specific ranges
for each modification and other illegal entries are given in the procedures
for each menu selection (paragraph 3-8).
After legal modifications have been entered, the character "8" is
entered to save the data base on the disc and relock the terminal keyboard.
f. Deletion of Entries. Operator entries can be deleted anytime prior to
pressing the RETURN key. To delete a single character press the DELETE key;
to delete an entire line press the CTRL and U keys.
2. Data Base Log. The system data base provides printouts of broadcast
initiator RTS's for each of the ten available broadcast lists, and for RTS's
assigned to each of the ten broadcast lists. For each menu selection on the
data base it is recommended that a list of each item be composed and
permanently logged (per site procedures) for each available disc. The log
lists should be updated after the modifications are entered in the program to
maintain an up-to-date running log.
3-8. Static Data Base Modification Procedures.
a. Access Procedure. The data base cannot be accessed to perform
modifications without entry of a password related to the disc in use. The
password is entered after the statement: SWITCH ON LINE, NO. RT's IN SERVICE
= XX (where X'is a digit 0-9). This statement will appear only after system
initialization. The password may be entered anytime the keyboard is locked.
When the password is entered, it is not typed out. The following is a valid
password entry, where entries underlined are operator entry by keyboard; (CR)
is the carriage RETURN key. All other line items are terminal printouts
controlled by the computer program.

The static data base has now been accessed, the menu selections are printed
out, and the keyboard is enabled to perform modifications.
Prior to any modifications to the data base, the oper-
ator must be completely familiar with the sequence of
modification entries and modification procedures in
following paragraphs to prevent unauthorized opera-
tions of the terminal.

b. Modification Procedures.
An RT Class Mark Modification does not affect the
present broadcast initiator lists or broadcast lists.
It is therefore possible. that unauthorized broadcasts
could take place if these lists are not reviewed for
modification and modified as required after the RT
Class Mark Modification is entered.
(1) Modifications to the data base must follow a specific sequence to
prevent unauthorized broadcasts due to class mark modifications. The operator
sequence of modification entries is given in flow chart form in figure 3-8.
Follow the flow chart from top to bottom selecting the modifications desired
on the left hand side. When operator action is directed (rectangular blocks),
proceed to the referenced paragraph for the modification procedures. The
sequence directs that after the last modification request, the operator enter
menu 8 (SAVE DATA BASE ON DISC - RELOCK TERMINAL). This entry writes all
modifications on the diskette, exits the data base, and locks the terminal
keyboard.
Modifications written into the disc in use will make
it different from duplicate discs in storage (see
paragraph 3-9 for duplication of discs).

Modifications to the data base can be saved on
the disc on an individual basis if desired.
However, since entry 8 exits the data base, the
password must be reentered for each subsequent
modification entry.
(2) Modification procedures are given for each menu selection. Each
procedure has a brief explanation of the function. A complete description of
programmable functions is given in paragraph 2-7. Each procedure provides a
valid and illegal operator entry sample. Underlined characters in the samples
are operator entries by keyboard. The carriage return (RETURN key) is
indicated by (CR). All other characters are response printouts controlled by
the computer program.
c. Timer Modifications (Menu Select No. 1).
(1) Two timers are available for value modification and are defined as
follows:
Timer No. 1 (T1) = Elapsed time between send and remove dialtone
and send invalid number signal. Programmable from 1 to 35,000 seconds in 1
second increments.
Timer No. 2 (T2) = Elapsed time between send and remove broadcast
alert. Programmable from 1 to 35,000 seconds in 1 second increments.
(2) A valid timer modification is shown in sample 1. Timer identities
must be either number 1 or 2 and the time must be within the specified range
of 1 to 35,000 seconds or declared an ILLEGAL ENTRY as shown in sample 2.

e. RTS or CSS In or Out-of-Service Modifications (Menu Select 3).
All RTS's should never be marked out-of-service.
At least one RTS at any one time must be marked
in-service or the system program will not run.
(1) When an RTS is marked out-of-service, the CSS switch will not
examine its line and dialtone will not be sent to the out-of-service RTS.
Callers to an out-of-service RTS will be sent an out-of-service tone signal.

q. RTS Broadcast List Modification (Menu Select No. 5J,.
(1) Ten broadcast lists are available for m)dif c ,t ion nuumber'. :10
through 89). This menu selection allows the operator to list the present
RTS(s) on the broadcast lists and add or delete RTS's from. each list. The
maximum number of RTS's that can be assigned to a list is 60. The first RTS
entry on the list establishes the list class marking and all RTS additions to
the list must have the same class mark. Example: (where number in
parentheses is the RT class mark assigned in Menu Select 2) Present broadcast
list is RTS's 12 (2), 13 (2), 14 (2). The addition of 15 (3) or 16(1) to the
list is an illegal entry. RT 15 (3) can be added to the list by one of two
methods: 1) modify RT 15 class mark from 3 to 2, or 2) delete the entire
present list and build a new list with the first entry being 15 (3). The new
list from this point on will accept only the addition of class mark 3 RTS's..
The same methods apply to RT 16 (1).
To prevent unauthorized broadcast operations when
broadcast lists are modified, review the associated
broadcast initiators list (Menu Select No. 6) to en-
sure that it has a higher or equivalent class marking
than the broadcast list.

h. Broadcast Initiator List Modification (Menu Select No.
(1) Ten broadcast initiator lists for each of the ten broadcast lists
(numbers 80 through 89) are available for modification. This modification
allows the operator to list the present RTS(s) on the broadcast initiator
lists and add or delete RTS(s) from each list. The maximum number of RTS's
that can be assigned to a list is 60. The first RTS entry on the list
establishes the list class marking and all RTS additions to the list must have
that same class mark. Example: (where number in parentheses is RTS class mark
assigned in Menu Select 2) Present broadcast initiator list is RTS's 12 (2),
13 (2), 14 (2). The addition of 11 (1) or 15 (3) to the list is an illegal
entry. RTS 11 (1) can be added to the list by one of two methods: 1) modify
RTS 11 class mark from 1 to 2 or, 2) delete the entire present list and build
a new list with the first entry being RTS 11 (1). The new list from this
point on will accept only the addition of class mark 1 RTS's. The same
methods apply to RT 15 (3).

i. Password Change (Menu Select No. 7).
(1) The password change allows the operator to enter a new password
for the diskette in use and verify the password entry prior to software entry
of that password. The password is changed if Y is entered after the prompt
statement VERIFY NEW PASSWORD. Any character entered other than Y after the
prompt statement will not change the password.
The password is diskette associated. Therefore, when
a password is changed for a diskette, all duplicate
diskettes for the ITS program will contain the old
password.
The New Password is printed out only during the pass-
word change. Tear the printout from the data terminal
and store per site procedures. The new password must
be related to the disc identity.
There is no ILLEGAL ENTRY statement for the Password
Change entries. The operator must have prior know-
ledge of what constitutes illegal entries.

j. Save Data Base on Disc-Relock Terminal (Menu Select No. 8).
(1) This entry (8) allows the modified data base to be saved on the
diskette. If a system ac power failure occurs prior to this entry, all
modifications entered by the operator are void and the data base item values
are the same as.previous to modification entries. In'this case, the,
modifications must be reentered after the system powers up. Normally, the
data base is saved after all modifications have been entered. During periods
when system power failures are frequent, it is recommended that the data base
be saved after each modification. The save data base on disc-relock terminal
(entry number 8) is entered after the prompt statement ENTER MENU SELECTION
NO., NULL = DIRECTORY ASSISTANCE. An ILLEGAL ENTRY statement will be printed
out only if the character entered is not within the range of 1 to 8.

a. General. A program on one diskette can be written on another diskette
using the RT-11 Peripheral Interchange Program (PIP) provided with the PDP 11
computer.
The ITS-W System Program cannot run during PIP
operation, therefore user network communication
is interrupted.
b. Procedure. To duplicate one of the diskettes, the following steps
apply:
(1) Place diskette to be duplicated into DXO (disc drive zero).
(2) Place blank diskette into DX1 (disc drive one).
(3) Press computer BOOT/INIT switch to INIT and release to BOOT.
(4) Perform the following keyboard entries and verify printout results

Section IV. MAINTENANCE
This section contains information on operator maintenance of the CSS.
Operator maintenance is limited to checks and services, and replacement of
fuses. For additional operator maintenance, consult the Digital Equipment
Corporation manuals listed in Operator section, paragraph 3-1, of this manual.
4-2. Checks and Services.
To ensure that the CSS is always ready for operation, a systematic
inspection will ensure that defects may be discovered and corrected before
serious damage or failure occurs. The operator checks and services on the
equipment is listed in table 4-1. Defects discovered when the system is
running should be noted and correction made as soon as operation of the system
is shut down. Immediately notify proper authorities if a deficiency is noted
during operation which would damage the equipment. Record all deficiencies
together with corrective action taken.
4-3. Cleaning.
a. Remove dust, dirt and other foreign matter with a soft bristle brush
and a clean lint-free cloth.
b. Remove grease fungus and ground-in dirt with a lint-free cloth dampened
with a detergent and water solution.
c. Clean cabinet air filters by washing thoroughly with detergent and
water solution. Rinse with clear water and allow to dry.

4-4. Fault Isolation and Corrective Action.
Fault isolation is performed by observing abnormal indications during
system power-up, while the system is in the normal run mode, or during
operator entries at the data terminal. Normal indications are given for these
items in the Operation section of this manual. Should an ac power failure
occur, first check all CSS equipment circuit breakers to ensure that they are
in the "on" position. Operator corrective action is limited to replacement of
fuses located on the dc power supply (2A4) and the data terminal (Unit 1), and
other operator actions not requiring parts replacement. Table 4-2 lists
trouble symptoms and most probable cause and corrective action.
To prevent possible damage to equipment, ensure that
power is removed from equipment before replacing
fuses.
