Common Conversions

      1. The following definitions are used in this specification:

        1. Accuracy: The measure or characterization of difference between an offender’s location as determined and reported by the EM device and the offender’s actual location.

        2. Active Monitoring: An approach to offender monitoring that uses cellular capability to accomplish near real-time collection and transmission of device location and status data.

        3. Active: Mode in which the device transmits location reports, alerts, and event notifications as soon as they are obtained subject to the time delay imposed by the cellular network.

        4. Adequately charged battery: A unit charged to meet the definition of a “fully charged battery” within the past six hours.

        5. Alert: (1) A notification that an offender wearing a monitoring device has engaged in activity of interest to the supervising entity (e.g., zone breach, tamper), or that a device parameter of interest has changed (e.g., low battery power); or (2) An event generated or recorded by an offender monitoring system that requires notification to CSC for review.

        6. Bidder or Solution Provider: A "Bidder" is defined as the entity submitting a proposal in response to this RFP. This term is synonymous with "Solution Provider", since the bidder will be providing a solution to CSC which includes hardware (e.g. the electronic monitoring devices), software (e.g. the electronic monitoring application), and related services.

        7. Bracelet: The body-attached portion of an EM device, usually affixed to an offender’s ankle.

        8. Breach: A breach is an event in which an offender has acted contrary to the terms of his or her conditional release and or court-ordered restriction(s) (e.g. left authorized location when not scheduled to do so, tampering with equipment).

        9. Care: Cleaning, sanitization, and storage of an EM hardware unit.

        10. Cellular Mode: Is a method used by EM device to attain its current position stationary or moving. Localization occurs via multilateration of radio signals between (several) radio towers of the network.

        11. Cellular Technology: A cellular network or mobile network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. When joined together these cells provide radio coverage over a wide geographic area. This enables a large number of portable transceivers (e.g., mobile phones, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations.

        12. Circumvention: An action intended to frustrate or defeat proper EM device function.

        13. Communications Failure: The EM device is unable to establish communications with the EM Data Centre to upload data.

        14. Contractor: The company selected as the successful bidder.

        15. CSC National Monitoring Centre: is CSC’s centralized operational unit that provides various services and supports a variety of programs, 24 hours a day, 7 days a week to all 5 CSC regions (Pacific, Prairies, Ontario, Quebec and Atlantic).

Reliability, availability, recovery, and unavailability are related concepts. The unavailability is the proportion of a time span that a system is unavailable or offline. This is usually a result of the system failing to function because of an unplanned event, or because of routine maintenance.

        20. EM Data Centre: The service provider’s physical facility that houses the servers and other equipment necessary to receive and process monitoring data from offender-worn devices;

        22. Exclusion zone: A user-defined area which a monitored offender must remain outside of during specified periods.

        23. Event: An event is any action recorded by the Electronic Monitoring system that is time-stamped, sent, logged, and reportable, including diagnostic tests, transmitter in or out of range occurrences, power and telephone line interruptions, etcetera. Events may also be alerts when they occur as a result of offender behaviour (e.g. leaving during a curfew period, tampering with equipment), or equipment issues (e.g. low battery power, loss of location).

        24. Field-replaceable system-level components: Is a part or assembly that can be quickly and easily removed from an EM Device by the EM Service provider or CSC without destructively opening the hardware component casing (e.g., batteries, straps).

        25. Firmware: (1) the fixed, usually small, programs and or data structures that internally control various electronic devices; (2) software stored in read-only memory (ROM) or programmable ROM (PROM) that often is responsible for the behavior of a system when it is first switched on.

        26. Fully charged battery: The quantity of electricity in Ah (ampere-hours) declared by the manufacturer that a single-cell battery can deliver after being charged for a two hours period for devices.

        27. Location methodology: An approach, or a combination of approaches, used to determine the location of objects (e.g., GPS, AFLT, inertial navigation).

        28. GPS mode: EM device receives signals from the visible satellites and sends the coordinates to EMS server.

        29. Inclusion zone: A user-defined area within which an offender who is subject to electronic monitoring must remain during specified periods.

        30. Inspection: Observation using one or more of the five senses, simple physical manipulation, and mechanical and electrical gauging and measurement to verify that the item conforms to its specified requirements.

The malfunction or unavailability of a mission critical resource will cause a serious and or wide-ranging impact on the organization and its ability to conduct its core business functions. The offender Electronic Monitoring program solution, once implemented, will be considered a mission critical application.

        38. Monitoring system software: The various computer programs used to direct the operation of an EM device, especially as it relates to the interface with the end user. These programs may exist within the monitoring devices themselves (firmware), within the manufacturer’s computer systems, or resident on computers controlled by the end user.
