1.6 TC12 SYSTEM OVERVIEW
TC12 is a telecommunications system designed for Urban Traffic Control (UTC). It
consists of a number of Outstation Transmission Units (OTUs) positioned in the
traffic controllers or detector cabinets. These communicate with a central office
containing a number of Instation Transmission Units (ITUs). Communication
between the two is by means of private wire telephone lines, which can be
operated at different baud rates and signal levels.
The ITU sends a Control message to the OTU that will cause the OTU to form the
appropriate Reply message, which it will send back. These messages are of
configurable size depending on the amount of data transfer needed.
The ITU connects to a Traffic Control Computer (TCC) system consisting of one or
more UTC TCC computers and one or more PCs communicating with each other
via an Ethernet link. This system drives the ITU modems, which communicate with
the OTU via the telephone lines.
The ITU also drives the System Fault Indication Panel (SIP) which indicates, by
means of LEDs and an audible alarm, failures in the TCC. The SIP is housed in
the ITU cabinet but there is also the option of driving a remote SIP. The ITU can
also be used to drive a TC8 Instation.
There is also facility for an Instation Test Set which can be used to measure signal
levels and monitor communications (both data and errors) on the telephone lines.
It can also be used to take the place of either Instation or Outstation for testing.
The Instation comprises of one or more Traffic control computers (TCC) and one
or more Instation Transmission Units (ITUs). The ITU cabinets are 32U high with
grey panelling and a smoked glass front door.
Traffic Control Computer
The TCC is a system containing a minimum of one machine and one PC per ITU
cabinet. The UTC TCC system communicates with the PC(s) via an Ethernet link.
More than one UTC TCC will be used should the number of modems required
demand it.
Instation Unit
The ITU cabinet is fitted with a PC at the top, and space for up to four racks below
it. These racks will be either ITU or Digital output racks, but the bottom space can
be used for an OTU if required. There is also a mains distribution system with
spare sockets, and facility for mounting a PSTN modem that would connect to the
UTC TCC to allow remote interrogation.
System Fault Indication Panel
The System Fault Indication Panel (SIP) is positioned in front of the PC and
houses LEDs to warn of various failures. There is also an audible alarm on the SIP
that can be cancelled by a switch next to it or disabled by a switch on the PSU
board.
ITU Rack
A full ITU rack contains three types of board; four modem boards, four transformer
boards and a power supply board.
The modem board has four modem chips that communicate with the PC via a V.24
link. These modems are connected to the OTU via the telephone lines in either
radial, multidrop or multipoint format. There is also a pair of test jacks on the
modem board to allow connection to the Instation test set to monitor
communications data and measure signal levels.
The transformer board is used, when the system is in radial configuration, to split
each modem to up to eight telephone lines. This gives a maximum of 128
telephone lines per rack.
The PSU board supplies power to the ITU rack. It also interfaces between the PC
and the SIP and allows connection to a TC8 ITU rack. This facility would be used
should a TC8 system be expanded with TC12.
The Digital output rack contains one Instation rack Power Supply Card and
between one and sixteen Digital Output boards, each capable of driving 64 LEDs
at up to 30 V 25 mA. There are two variants of Digital Output board, one sources
current and the other sinks current. The system could be used for any application
requiring digital output, not just wallmap driving.
Instation Test Set
The Instation Test Set (ITS) is housed in an attaché case, and connects to either
the Modem PCBs or the OTU PCBs. It contains a PC, a modified ITU modem
board, an ITS logic board and two power supplies. One power supply is the same
unit as on the PSU board in the ITU rack and is used to power both the boards,
whilst the other is the PC PSU. The ITS provides for connection to the Modem or
OTU board as well as use as a handset.
Outstation Test Set
The Outstation test set is a portable unit housed in a small grey metal case. It
requires a mains supply for operation and two cable forms with which to interface
with the OTU being tested.
Freestanding Outstation
The freestanding outstation is a rack that can be bolted into any Traffic Controller.
It contains a Power Supply, an OTU PCB and up to four detector PCBs. Two
connectors allow the OTU inputs and outputs to be wired up to the controller and
or detector cards, and the OTU is delivered with a cable for this purpose. The
outstation can also provide an LMU facility, and a connector allows current and
voltage monitoring transformers to be attached for this purpose. There is a pair of
test jacks on the board to allow connection to the Instation test set to monitor
communications data and measure signal levels.
Figure 1 and Figure 2 show diagrams of example system connections.
Integral OTU
The integral OTU is a printed circuit card that can be installed in a T400 or ST800
Traffic Controller. It is a version of the T400 Ancillary processor with suitable
firmware to configure it to be an OTU. A single 40-way ribbon cable connector
supplies communication to the controller and all power. A 60 way ribbon cable
connector is fitted for connection to current and voltage monitoring transformers
for use as an LMU. There is no provision for detector inputs - the controller
supplies all detector information.
Connection to the line is via a captive lead terminated in a 6-way BT plug.
There is a pair of test jacks on the board to allow connection to the Instation test
set to monitor communications data and measure signal levels.

C12 Instation PC Software Installation
12 PC Software is supplied on a single floppy disk. There are 2 versions of
software currently in use, Version 7.4 should be used if it is
pdat an existing installation; Version 8.3 should be used on all new installations.
he installation procedure for both software versions is basically the same, but
n 8.3 has the following additional features:
•
Allows a PC processor card with onboard Ethernet to be used
•
An option to disable the playing of the start up tune
•
An option to disable the driving of the SIP.
• The default screen display shows the state of the TCC Ethernet
and the System and Operational alarm states.
C12 PC does not have a built-in monitor, a VGA monitor should be
ed before starting the software installation process.
C should be plugged directly into the mains, and not via the mains

The earth strap comes with a bolt (+ star washer) and tag on one end which is
attached to the hole situated below the power supply on the PCB (see Figure 7 for
position of ground hole).
The switches on the PSU PCB should be set as follows:
(See Figure 8 for diagrams of switch settings)
This should be set to '1'. If a second rack is fitted in the Instation then the position
of the switch, on the PSU Board in the second rack, does not matter. If there is
more than one PC connected to the same Ethernet link, the switch should be set
to 2 for the PSU Board connected to the second PC, 3 for the PSU Board
associated with the third PC, etc. The switch setting should correspond to the last
digit of the TC12 PC SCN in the associated UTC System’s database.
This is a 4-way DIL switch. The usual setting for this switch is as follows:
The function of this switch is to enable certain inputs to the board, to cause the low
frequency alarm tone to sound.

2.4.8 TC12 Instation PC Help / Diagnostic Screens
If a monitor is attached to the TC12 PC (note the TC12 Instation Test Set can be
used as the monitor) a number of Help/Diagnostic screens are available in the
TC12 PC Software. These are described below.
2.4.8.1 Help screen, Key to Press 'H'
This Screen lists all of the diagnostic and help screens and keys to be pressed to
activate them.
2.4.8.2 First 22 TC12 OTUs on an Instation, Key to Press '2'
This screen displays the replies received from the first 22 TC12 OTUs on an
Instation. It displays each OTU’s reply on a separate line on the screen, OTU 0 at
top. This screen only shows the first 22 OTUs on an Instation but can be used to
obtain indication of the health of the system.
The first eight digits on a line are characters indicating what errors were detected
with the particular OTU reply. The characters represent the errors as follows.
A = Address error
M = MT (message transfer) bit set in reply
N = No reply
S = Short reply
C = reply CRC error
P = parity error (not used in TC12)
F = framing error in reply
O = over run error on reply message
The remaining characters on each line are the hexadecimal representation of the
reply bytes (__ means no data) for that OTU, each line is the correct length
(number of characters) for the number o
f reply bytes for the OTU.

This screen shows the current, worst, best and average free time as percentages.
NB After re-booting the Instation PC worst percent free time goes to 0%, as during
initialisation it is allowed to use all time available for processing. To determine the
worst percentage free time during normal operation reset counters once operating
normally by pressing 'Z'. The worst percentage free after five minutes should be an
accurate figure for the system.

3.2.2.3 Configuring the Switches on the Outstation PCB
Before any connectors are attached to the Outstation PCB, the configuration
switches need to be set up as described below. Refer to Figure 18 or Figure 19 for
the position of the switches on the PCB.
There are four switches on the PCB.
S2 = Lithium Battery On / Off Switch See Figure 20
S3 = Line Level Switch See Table 5
S4 = 2 / 4 Wire Select Switch See Figure 21
S6 = 600 Ω / High Impedance Switch See Figure 22
These are set as follows:
1. Slide the PCB out of the card guides.
2. S2 - Lithium Battery On / Off Switch
Ensure that the Lithium Battery Switch (S2) is set to the ON position.
3. S3 - Line Level Switch
Ensure that the Line Level Switch (S3) is set to the required line levels. These are
stated on the installation information sheet for the Outstation. Table 5 shows
switch settings corresponding to the different levels. Switch S3 is a 6-way DIL
switch. Switch positions 1 to 4 set the Output Power and switch positions 5 and 6
set the Receive Threshold.
For UK use the output power is always set to -13dBm and the receive threshold is
set to –39dBm.
