Section I. GENERAL INFORMATION
W
1-1. Scope.
This manual describes the Remote Terminal Subsystem (RTS) (figure 1-1),
which is part of the Washington Area Image Transmission System (ITS-W). This
manual is directed to personnel who will operate the RTS equipment at remote
and centrally located sites of the ITS-W network. To familiarize the operator
with the various modes of operation and operating procedures discussed in the
following sections of this manual, the overall ITS-W network is discussed
briefly.
1-2. Description.
a. Purpose and Use. The purpose of the RTS is to securely transmit
documents such as photographs and printed matter and receive transmitted
documents from other RTS's in the ITS-W network. The transmitted document is
recorded and processed at an image size ratio of 1:1. Each RTS has the
capability for secure telephone communication in the network which is used to
establish initial connection between RTS's for facsimile transmission and
voice communication.
b. ITS-W Network. The ITS-W network is a secure multisubscriber
high-resolution, photo facsimile transmission system. The ITS-W (figure 1-2)
is organized as a star network of up to 60 remote subscribers (RTS's) with the
Central Site Subsystem (CSS) as the hub. The CSS is an automatic distribution
and switching network the prime function of which is to interconnect serial
1.544 Mb/s data lines from and to the remote terminals to create feedthrough
data channels between terminals. All data that enters or exits the remote
sites and the central site is via COMSEC (communication security) and link
subsystem equipment. Multiple RTS's may be located at a remote site and at
the central site .

(1) The CSS provides two types of connection service between RTS's,
full duplex and broadcast. The connection setup, similar to a standard
telephone network, is initiated by a telephone handset and keypad located on
the RTS control panel. The RTS operator desiring to initiate data
transmission, removes the handset from the cradle and receives a dialtone
signal from the CSS indicating that the CSS is ready to provide service. The
calling party then enters the connection request (terminal identity) by
pushbutton on the telephone keypad. The CSS then determines if the requested
or called party is a valid connection (in-service and of a proper class mark)
in the non-busy or on-hook condition. If valid, the CSS will simultaneously
ring the called party while providing ringback to the calling party. If an
invalid connection is requested (invalid number, busy, or out-of-service) the
CSS signals the calling party so that he may hang up his handset. If a valid
connection is requested and the called party answers his telephone, the CSS
stops the ring and ringback at both ends and interconnects both parties for
full duplex communication. The connected parties can then communicate via
voice over the handset and either the calling or called party can transmit
facsimile data simultaneously with or without voice data.
(2) The CSS broadcast service allows a single two-digit number to be
dialed at an RTS authorized for broadcast operation, and if the call is valid,
the calling party is connected to up to 59 RTS's for simplex transmission of
data. Voice and facsimile transmission is then one way, from the broadcasting
RTS to the receiving RTS's.
(3) The CSS also provides individual RTS class marking which allows
only the higher class marked RTS's to initiate a connection with equivalent or
lower classed marked RTS's.
c. RTS Functions. The RTS (figure 1-3) consists of a digital LASERFAX
transmitter, a digital LASERFAX receiver and a Voice Control Unit (VCU) with
control panel. The facsimile transmitter and facsimile receiver are the
terminal devices that convert from hardcopy to digital data and digital data
to hardcopy, respectively. The VCU is the data processor and controller for
the RTS and interfaces with the transmitter, receiver, control panel, and the
1.544 Mb/s full duplex data link.

(1) The transmitter accepts either opaque copy or positive
transparency documents up to 11-inches by 14-inches, scans the document with a
laser beam, digitizes the detected information, and routes the informaton to
the.VCU. Voice information from a telephone handset is also routed to the VCU
and digitized. The VCU adds control information and formats the facsimile and
voice information into a suitable format for data transmission over the 1.544
Mb/s data link.
(2) In a like manner, the VCU accepts formatted information from the
1.544 Mb/s data link and deformats the control, facsimile and voice infor-
mation. The digital facsimile data is routed to the receiver where it
modulates a laser beam which is focussed on light-sensitive paper to reproduce
the transmitted image. The digital voice data is converted to an analog voice
signal by the VCU and routed to the telephone handset.

(3) The RTS has the capability of routing network data via the VCU to
slave digital LASERFAX receivers. Slave receivers are individually selected
on the VCU control panel. All slave receivers receive the same data when "ON".
1-3. Physical Configuration.
a. The RTS configuration shown in figure 1-4 consists of a Model 3322
Digital LASERFAX Transmitter, a Model 3322 Digital LASERFAX Receiver
(recorder) and a Voice Control Unit, part number 616964. All three units are
free standing and placed on a console desk top. The bottom portion of the
console houses a dc power supply for the VCU. Ac power is routed from an
external source through conduit to a junction box containing the main circuit
breaker located on the front of the console below the desk top. From the
circuit breaker, power is routed through a filter and then fed as RED AC power
to the dc power supply, the receiver and the transmitter.
b. The Model 3322 Digital LASERFAX Transmitter shown in figure 1-5 is
designed to accept either a transparent film or opaque paper. Four levels of
object enhancement are selectable on the front panel. Documents are inserted
in the top of the unit using an alignment mark on the input guide of the slot
cover. Document transmission is manually started and can be manually stopped
by controls on the front panel. The document exits the unit through a slot on
the front of the unit stopping transmission automatically. Transmission time
for a normal 11-inch length copy is approximately one minute from start to
stop. The unit has a latching cover hinged on the rear panel for maintenance
access. When the cover is up, an interlock switch prevents ac power from
being applied to the unit power supplies. All signal input and output cables
and fuses are located on the rear panel.

c. The Model 3322 Digital LASERFAX Receiver shown in figure 1-6 contains
all of the equipment required to automatically reproduce and process
transmitted images. The receiver enclosure includes a copy stacking tray for
up to 25 copies. The control panel of the unit provides power on and rapid
advance controls, record and process indicators, an indication when the paper
supply is low and, an indication if the receiver is inoperable. Total
processing time for a maximum length copy (14 inches) is approximately 1.5
minutes. The unit has a latching cover hinged on the rear panel for
maintenance access and to load a reusable paper cassette. The cover has an
interlock switch which prevents power from being applied to the unit when the
cover is up. All signal input and output cables and fuses are located on the
rear panel.
d. The Voice Control Unit shown in figure 1-7 contains a latched front
panel that is hinged on one end to enable maintenance access. The front panel
contains all operator controls required for selecting receiver and transmitter
local or network operation. Network indications are provided for connection
status, and receiver status of each remote terminal in the network. Alarm
indications are provided for loss of crypto synchronization and for excessive
non facsimile use of the terminal. A standard telephone handset with keypad
is provided for voice communication and dialing. Additional switches enable
selection of up to five slave facsimile receivers (optional equipment). The
rear panel contains connectors for the master and slave receivers,
transmitters, and the data link.

2-4. Input Document Loading Procedure (Facsimile Transmission).
The input document to be transmitted (refer to figure 1-8) can be either a
film transparency which must be used with a frosted Mylar backing sheet or an
opaque copy with a mat finish and white background, 3 mils to 44 mills thick,
11 inches wide maximum and 6 inches wide minimum, 14.5 inches long maximum and
6 inches long minimum. Since the transmitter has an active scan width of
8.125 +0.125 inches, an 8.5 inch document will have a minimum of 0.125 inch
unscanned margin on the left hand side of the document. Documents that are
wider than 8.5 inches will have a wider unscanned margin. The active scan
length is 5.5 inches to 14 inches leaving an unscanned margin of 0.375 inch at
the top of the document and 0.125 inch at the bottom of the document. To load
the document in the transmitter, proceed as follows:
a. Examine document for gray levels (refer to paragraph 2-6.j). If object
enhancement is desired, determine which enhancement curve will produce best
results. If desired, select one of four levels by stepping the transmitter
OBJECT ENHANCEMENT pushbutton. If no object enhancement is desired, the
switch must be stepped until all four sections of the indicator are
extinguished.
b. If positive film transparency is to be transmitted, align a frosted
Mylar backing sheet of equal size on the reverse side of the transparency.
The frosted side of the backing sheet should be against the transparency.
c. Insert document (opaque copy or transparency) in input slot with the
image facing out toward front of slot (facing operator). For transparencies,
ensure that backing sheet is toward rear of slot.
d. For 8.5 inch wide documents or smaller, align left edge of document
with scribe mark on back of input slot cover (figure 1-5). For documents
wider than 8.5 inches, place document to left of scribe mark to even out
unscanned area margin if desired.

2-5. Operator General Information.
a. Class Marking. All RTS subscribers are class marked for the purpose
of limiting access to other RTS subscribers. Four levels of access with their
corresponding class marks are identified as follows:
Level 1 -has access to all subscribers.
Level 2 has access to all subscribers except Level 1.
Level 3 - has access to Level 3 and Level 4 subscribers only.
Level 4 - has access to other Level 4 subscribers only.
All calls to subscribers to which connections are prohibited by class marking
will not be connected and an invalid number information signal will be sent to
the calling party.
b. Address Number Organization. The following address groups are
assigned in the ITS-W network. Specific RTS addresses (terminal identities)
and Broadcast Lists are not given in this manual.
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
All calls to unimplemented subscribers or invalid numbers will be sent an
invalid number information signal.

2-6. Remote Terminal Operating Modes and Operational Sequences.
a. Full Duplex Mode. The full duplex mode of operation allows an RTS
operator to dial up another authorized remote terminal and establish a full
duplex connection (via the Central Site Subsystem) for simultaneous voice and
facsimile transmission and reception. Once a connection is established, both
the calling or called parties can transmit facsimile data.
b. Broadcast Mode. The broadcast mode of operation allows a broadcast
authorized RT operator to dial up to 10 broadcast lists and establish simplex
connection (via the Central Site Subsystem) with all RTS's on the list.
During broadcast, facsimile transmission and voice operation is simplex (one
way) from the broadcasting (calling) party to the receiving (called) parties.
The RTS will not simultaneously operate in broadcast transmit and broadcast
receive modes. Authorization for broadcast initiation is on an individual
list basis, modifiable through the CSS switch only.

c. Automatic and Manual Reception Modes. The automatic or manual
reception mode is manually selectable by the VCU control panel terminal
AUTO/MANUAL pushbutton. When the terminal is in the AUTO mode of operation,
the called RTS requires no operator intervention and images transmitted by the
calling operator are received and recorded automatically. No audible ring
will be heard. When the terminal is in the MANUAL mode of operation, the
called RTS requires operator intervention, i.e., the called operator must
remove the handset from the hook (when an audible ring occurs) to establish a
connection with the calling operator. The AUTO mode is normally used for an
unattended console.
d. Hold Submode and Automatic Link Termination. The hold submode allows
the RTS operator to hang up the handset after facsimile transmission has
started, in either the duplex or broadcast mode, and maintain the connection
as long as facsimile transmission is taking place. The RTS will automatically
terminate the connection after facsimile transmission and/or reception is
completed. The connection is also automatically terminated if the calling
party hangs up the handset prior to facsimile transmission and/or reception.
On-hook operation puts the terminal in a time-out mode after the connection
has been established where requests for subsequent document transmission must
occur within 15 seconds at the end of the previous document or the connection
is terminated. In the hold submode, the RTS will respond to a "remote call"
by producing an audible ring with the handset on-hook (paragraph 2-6 e.).
e. Remote Call. When RTS's are interconnected in the duplex mode, either
RTS can manually ring the connected RTS at any time whether the called RTS
handset is on-hook or off-hook. Calling operator action requires removing the
handset from the hook and pressing the keypad CALL button. When the RTS's are
interconnected in the broadcast mode, the authorized broadcast RTS can ring
all connected RTS's; however, the connected RTS's cannot ring the broadcast
RTS.

f. Handset Off Hook Alarm. The RTS's are designed specifically for
facsimile transmission and reception. Voice communication is used mainly for
coordination of facsimile operation. The system will automatically remind the
operator via the HANDSET OFF HOOK indication alarm that normal practices are
being violated. Normally, once an RTS operator has established a connection
with another RTS and the Network Connection ACTIVE indicator illuminates,
facsimile transmission should be initiated immediately. The HANDSET OFF HOOK
alarm indicator will not illuminate if the handset is off-hook during
transmission of document(s) or reception of document(s). If voice contact is
desired during transmission, the remote call feature described in paragraph
2-6 e. can be used. The HANDSET OFF HOOK alarm indicator will illuminate
under the following conditions:
(1) The handset is off-hook more than 15 seconds after the Network
Connection ACTIVE indicator illuminates and facsimile transmission has not
been started.
(2) The handset is off-hook more than 15 seconds after the end of the
last document transmission.
2. Remote Terminal Status. Real-time receiver status is displayed for
each network subscriber on the VCU control panel Receiver Status indicators.
During the BROADCAST ALERT period the status display is used to inform the
broadcast initiator as to the composition of the broadcast list and of the
status of the individual members of the broadcast list. Status display is as
follows:
The receiver status display can only be considered
valid for implemented terminals. The capability to
display status is limited in every terminal with the
capability being expanded as the network is expanded

h. Local Simplex Mode and Slave Receivers. The local simplex mode allows
the operator to select (on the VCU control panel) the master transmitter as
the source for the local master receiver and/or for the slave receivers. In
this mode the VCU remains on line and permits reception of control functions
such as "Broadcast Alert." The operator may elect to keep the master receiver
switched to the network during local simplex document transfers to the slave
receivers. This permits simplex reception of facsimile data and full duplex
voice operation with the network. Through local switch setup configurations,
individual slave receivers may be selected (up to five) to receive facsimile
data from the network, or facsimile data being transmitted to the network by
the local transmitter, or facsimile data directly from the local transmitter
in lieu of network operation. All possible switch setup configurations are
given in paragraph 2-7. When the master receiver is operating in LOCAL, a
busy status is sent to the network, however the Central Site Subsystem does
not mark the terminal as busy and will permit incoming calls to be attempted.
i. Self Call. A self call feature allows the operator to dial his own
number when not receiving a transmission and establish a simplex connection
through the Central Site Subsystem. This feature is used for maintenance
purposes so that an operator can transmit a document through the link to the
Central Site Subsystem and link back to his terminal receiver for recording.
j. Object Enhancement. The LASERFAX facsimile transmitter provides for
four selectable levels of object enhancement (OBJECT ENHANCEMENT four
section/pushbutton indicator). Proper use of this feature requires operator
experience to determine the type of object enhancement desired for a specific
document. It is recommended that the operator experiment with documents of
various pictoral content to gain the required experience. Normally, object
enhancement is not required for documents having good contrast. Where
documents have poor contrast or have large areas of light gray and dark gray,
(gray shades of limited range) object enhancement may be used to improve the
contrast of light or dark areas.

TRANSMIT STOP pushbutton. The following sequence of events will occur:
(1) The transmitting RTS facsimile transmitter will physically stop.
If the handset is on-hook, the RTS to RTS connection is terminated in 15
seconds if a new transmission is not started. If the handset is off-hook,
the network connection is not terminated; however, the HANDSET OFF HOOK
indicator will illuminate in 15 seconds if a new transmission is not started.
The document in the transmitter may be removed by
gently pulling the document out of the input or
output slot.
(2) At the receiving RTS, facsimile recording is stopped when the
transmitting RTS operator depressed the TRANSMIT STOP button, and paper is cut
and processed in the normal manner provided a minimum of six inches of copy
has been produced. If less than six inches has been exposed, the receiver
advances the paper and cuts it at six inches.

Section III. MAINTENANCE
This section contains information on operator maintenance of the RTS
receiver, transmitter, VCU and power supply. The troubleshooting procedures
in this section list the more common symptoms that may be encountered and
identify the most probable cause of the malfunction. General checks and
services are provided as a means of preventative maintenance.
3-2. Checks and Services.
To ensure that the RTS console and equipment 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 are listed in table 3-1. Defects discovered during
the operation of the equipment should be noted and correction should be made
as soon as operation has ceased. Stop operation immediately if a deficiency
is noted during operation which would damage the equipment. Record all
deficiencies together with corrective action taken.

3-3. 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 cleaning a detergent and water solution.
3-4. Equipment Troubleshooting.
a. To determine whether a malfunction exists in the local equipment rather
than with transmitted or received facsimile signals, the master transmitter
and receiver should be put in a (self call) configuration to determine whether
the observed trouble symptom is common to the communication network or came
from another remote terminal. This procedure is given in paragraph 2-8j. Do
not commence fault isolation operations until it is determined that the
observed fault is unique to the local equipment. To determine if local
equipment is at fault, perform the local simplex mode of operation as defined
in paragraph 2-6 h. and 2-7 b.
b. Tables 3-2 (receiver) and 3-3 (transmitter) give the most frequent
trouble symptom and probable cause. Corrective repair, in most cases, is
limited to replacement of fuses, lamps, and clearing paper jams in the
receiver. There is no operator maintenance requirements for the VCU, other
than lamp replacement. Table 3-4 lists the lamps, and table 3-5 lists the
fuses for the equipment. Paragraph 3-5 provides procedures for clearing a
paper jam, paragraph 3-6 provides procedures for lamp replacement and
paragraph 3-7 provides information on fuse locations.

If the copy does not exit within one minute after the end of reception,
RCRD indicator extinguished and PROC indicator illuminated, open the
light-tight Receiver cover, and manually extract the paper from the Recorder.
If the paper is jammed in the cutter assembly: 1) Disconnect the cutter
return spring (figure 2-5) and manually move the cutter shaft lever counter-
clockwise. This action will cause the blade to move forward, cutting the
paper. With the blade in the forward position the paper is accessable through
the access holes in the paper guide mounted on the rear of the moving blade.
2) Using appropriate tools (long-nose pliers, forcepts, etc.) remove all
paper from the blade assembly and paper guides. 3) Replace the return spring
removed above. Ensure that any paper scraps torn from the received copy are
removed as these may cause additional paper jams. With the cover open,
advance a strip of paper through the Recorder.
