Operation of ECB
Emergency Call Box is a communication system which provides drivers on roads and highways with ability to call and communicate with a highway attendance staff. Emergency Call Box (ECBs) are connected to an ECB controller unit in the control centre through standard single-mode optical cables. Road users can talk to ECB operators from any ECB on the road.
It is only necessary to press the provide call-button on the ECB to initiate a call. All other actions are taken by an operator at the ECB handling desk or through the ECB Console in control centre. With this an operator sets the ECB in communication mode.
Once one of the ECB is in conversation with control centre, any other user of any other ECB can also send a call signal (push-button on an ECB) and request a conversation to the Control Centre. The operator can put current conversation with an ECB “on-hold” and switch conversation to another ECB.
Also, operator can call any ECB by putting it in communication mode and generate calling signal from the ECB workstation. The Emergency Call Box (ECB) unit will be designed to provide the following functions:
• A motorist will push the call button (distinctly identifiable) to initiate a call from the ECB.
• The motorist will hear a ring tone, if the call is successfully initiated. Otherwise, if the line is busy, a busy tone is generated. An out of order tone will be generated when the ECB / network is not functioning.
• A ring tone at the ECB client unit accompanied by blinking of ECB icon in the ECB Workstation will indicate that a call has been initiated.
• The connection is established, once the operator lifts the telephone handset or by mouse action at the ECB Server/client. The operator can then converse with the caller.
• Once the call is received, it will be indicated at the ECB system by an audible tone and simultaneously on the ECB Console.
• Simultaneous calls will be displayed on the ECB console by indication of the new call. The operator can put the current call on hold, or else the current call can be terminated and the next call handled.
• Upon completion of the call, the operator will disconnect the call.
