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.

666/HE/43100/000 Page 4 Issue 9

TC12 Installation, Commissioning & Maintenance Handbook

The Outstation test set is used in place of the controller to both set Reply bits and monitor Control bits at the OTU.

666/HE/43100/000 Page 5 Issue 9

TC12 Installation, Commissioning & Maintenance Handbook

Instation

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.

TC12 Installation, Commissioning & Maintenance Handbook

Digital Output Rack

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.
