handbook associated with the equipment.
The equipment must be correctly connected to the specified incoming power supply.
The equipment must be disconnected/isolated from the incoming power supply before
removing protective covers or working on any part from which protective covers have
been removed.
The Outstation PCB contains a lithium battery that must be disposed of in a safe
manner. If in doubt as to the correct procedure refer to Siemens Instructions CP562
Only authorised/trained personnel are allowed to have access behind the doors/panels
of the TC12 Instation Cabinet. Users/operators must not attempt to access anything
behind these doors/panels.
Only an authorised/trained person (trained in the safety aspects of working on mains
powered equipment) is allowed to setup/change any switch positions in the Instation
equipment and/or use any of the free mains sockets within the equipment and/or
connect/use the TC12 Instation Test Set at the Instation.
If the Audible alarm on the system fault indication panel (SIP) sounds it should be
cancelled as required from the UTC TCC terminal. If the reason for the alarm is a
UTC TCC failure, an authorised/trained person (trained in the safety aspects of
working with mains powered equipment), should be asked to cancel the audio alarm,
using the audio off switch on the PSU PCB.

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.

drawing 667/GA/22635/000). This mounting panel is a hinged aluminium panel a
the back of the Instation. Each IMD Distribution Unit has two ribbon
P2 and P3. The other end of these ribbon cables connects to the two connectors,
labelled P2
One IMD module contains 16 25-way D-type connectors. A group of four DConnectors connect via a single 24-way cable to one modem PCB, see section
2.2.4.2s on one
modem PCB.
The IMD Cables should be secured to the bottom of the hinged IMD panel.
Note: If it becomes necessary to replace either the IMD distribution box or the IMD
PCB they should both be changed at the same time.
Note: Before fitting the card into the PC, the card and the distribution unit should
