Operational Scenarios and Functional Thread
Diagrams
  • An operational scenario is a description of how
    a state intends that their customers and the
    state, or the state and core infrastructure
    systems, should interact to accomplish key CVISN
    functions. An example was given in chapter 4.
    More examples are provided here.
  • The operational scenario is shown as a list of
    sequential steps. To differentiate between
    different time schedules, numbers are used to
    show the interaction between the applicant and
    the state, and the states update of snapshots.
    Those interactions occur as soon as possible
    after the initial application is received by the
    state. Letters are used to show the states
    connections to the clearinghouses, since that
    occurs at a regular period instead of being
    triggered immediately by the carriers actions.
  • Each operational scenario is illustrated by
    overlaying information onto the state system
    design template. The lines represent data flow
    between products, with arrows indicating the
    direction of flow. Each line is labeled with a
    number or letter. The complete set of lines
    constitutes a thread of activities that
    accomplish a function. Hence, the diagram is
    called a functional thread diagram.
  • This appendix provides examples of operational
    scenarios and functional thread diagrams. They
    are included for reference and as starting points
    for states that plan to implement similar
    processes.

Example 1 Operational Scenario Electronic
Screening EnrollmentCarrier Submits Electronic
Screening Applications to a CAT
  • Note Prior to enrolling, the carrier will
    examine the electronic screening policy
    disclosures of the states in which it operates
    and determine where it would like to participate
    in electronic screening.
  • 1. The carrier submits Electronic Screening
    Applications, via a Carrier Automated Transaction
    (CAT) system, which submits it to the Enrollment
    Agent States Credentialing Interface (CI), via
    an EDI X12 TS 286. Using the CAT, the carrier
    may perform any of the following functions. The
    input required for each function is also listed.
  • Carrier enroll request carrier ID,
    participation request, other state required data.
  • Vehicle enroll request carrier ID, vehicle ID
    (VIN), transponder ID, participation requests,
    other state-required data.
  • Add/update carrier supplemental carrier ID,
    vehicle ID (VIN), transponder ID, participation
    requests, other state-required data.
  • Add/updated vehicle supplemental transponder
    ID, participation requests, other state-required
    data.
  • Status query.
  • Note The state in which the carrier enrolls is
    referred to as the Enrollment Agent State, and
    the other states that the carrier enrolls to
    participate in are referred to as Additional
    E-Screening States.

Screening Applications to a CAT
  • 2. The Enrollment Agent State CI will check for
    existing carrier and vehicle snapshots. (This
    process assumes that these snapshots exist, based
    on prior vehicle registration.) The CI queries
    the Enrollment Agent State CVIEW for a carrier
    and vehicle snapshot, via an EDI X12 TS 285.
  • 3. CVIEW passes the carrier and vehicle snapshot
    to the CI, via EDI X12 TS 285.
  • Note If snapshots do not exist, the enrollment
    request will be rejected, and the CI sends an EDI
    X12 TS 286 to the CAT. The carrier is required
    to perform vehicle registration prior to
    e-screening enrollment.
  • 4. The Enrollment Agent State CI stores the
    enrollment request data and is the authoritative
    source for this information. The CI processes
    the request and sends carrier and vehicle
    snapshot segment updates to CVIEW, via an EDI X12
    TS 285. These segment updates modify the
    e-screening participation fields in the affected
    snapshots.
  • 5. If the request includes carrier participation
    in the Enrollment Agent States
    e-screening program, CVIEW forwards the carrier
    snapshot to the E-Screening Enrollment system,
    via an EDI X12 TS 285.

6
Example 1 Operational Scenario Electronic
Screening EnrollmentCarrier Submits Electronic

  • 6. The state either approves or disapproves the
    carriers participation in this states
    E-screening program. The E-Screening
    Enrollment system is the authoritative source for
    the state acceptance decision. The Enrollment
    Agent States decision is transmitted to CVIEW as
    a carrier snapshot segment update, via an EDI X12
    TS 285.
  • Note The state may choose to contact the
    carrier for reasons such as
  • Set up a billing account
  • Sign agreements or documents
  • Obtain additional information.
  • 7.The Enrollment Agent State CVIEW sends carrier
    and vehicle snapshot segment updates to the
    Roadside Operations system, via EDI X12 TS 285.
    Snapshots are used at the roadside when making
    the bypass/pull-in decision.
  • 8. The Enrollment Agent State CVIEW sends carrier
    and vehicle snapshot segment updates to SAFER,
    via EDI X12 TS 285. These updates include the
    participation request data and Enrollment Agent
    State acceptance decision.
  • 9. SAFER sends the carrier and vehicle snapshot
    segment updates to Additional E-Screening State
    CVIEWs, via EDI X12 TS 285. Transponder ID
    information is passed only to states where the
    carrier has requested participation.

  • A. The Additional E-Screening State CVIEW
    forwards the carrier snapshot to the
    E-Screening Enrollment system, via an EDI X12 TS
    285.
  • B. The Additional E-Screening State enrollment
    system processes the request and either approves
    or disapproves the carriers participation. The
    E-Screening Enrollment system transmits the
    states decision to CVIEW as a carrier snapshot
    segment update, via an EDI X12 TS 285.
  • C. The Additional E-Screening State CVIEW sends
    carrier and vehicle snapshot segment updates to
    the Roadside Operations system, via EDI X12 TS
    285. Snapshots are used at the roadside when
    making the bypass/pull-in decision.
  • D. The Additional E-Screening State CVIEW sends
    carrier and vehicle snapshot segment updates to
    SAFER, via EDI X12 TS 285. These updates contain
    the acceptance decisions.
  • E. SAFER sends the carrier and vehicle snapshot
    segment updates to the Enrollment Agent State
    CVIEW, via EDI X12 TS 285.
  • F. The Enrollment Agent State CVIEW sends the
    carrier and vehicle snapshot segment updates to
    the CI, via EDI X12 TS 285.
  • G. Enrollment Agent State CI passes acceptance
    status to CAT, via EDI X12 TS 286.
  • Note Multiple TS 286 messages may be
    transmitted at various times as each state
    modifies its acceptance decision.

    285. Snapshots are used at the roadside when
    making the bypass/pull-in decision.
  • D. The Additional E-Screening State CVIEW sends
    carrier and vehicle snapshot segment updates to
    SAFER, via EDI X12 TS 285. These updates contain
    the acceptance decisions.
  • E. SAFER sends the carrier and vehicle snapshot
    segment updates to the Enrollment Agent State
    CVIEW, via EDI X12 TS 285.
  • F. Carrier and vehicle snapshots may be viewed by
    the Electronic Screening Enrollment administrator
    by performing queries against the Enrollment
    Agent State CVIEW. The query responses from
    CVIEW will be via EDI X12 TS 285.

Example 2 Operational Scenario Electronic

Administrator Handles Enrollment Function
  • Step 2a CAT formats the request and sends a TS
    286 to the Enrollment Agent State CI
  • Carrier enroll request
  • Carrier vehicle enroll request
  • Add/update carrier supplemental
  • Add/update vehicle supplemental
  • Status query.
  • Step 2b Enrollment Agent State CI will check
    for existing carrier and vehicle snapshots.
    Process assumes that these snapshots exist, based
    on prior vehicle registration. CI sends a TS 285
    snapshot request to the CVIEW.
  • Step 2c Enrollment Agent State CVIEW will
    return the TS 824.
  • Step 2d If snapshots do not exist, request will
    be rejected (CI sends TS 286 to CAT). The
    carrier is required to perform vehicle
    registration prior to e-screening enrollment.

  • Step 3 Enrollment Agent State CI stores the
    enrollment request data and is the authoritative
    source for this information. CI processes the
    request and sends carrier and vehicle segment
    updates (TS 285) to CVIEW. These segment
    updates modify the e-screening participation
    fields in the affected snapshots.
  • Step 4 If the request includes carrier
    participation in the Enrollment Agent States
    E-screening program, CVIEW subscription
    processing forwards the carrier snapshot (TS 285)
    to the E-Screening Enrollment system.
  • Step 5 E-Screening Enrollment system (for
    Enrollment Agent State) processes the request.
    The state may choose to contact the carrier for
    reasons such as
  • Set up billing account
  • Sign agreements or documents
  • Obtain additional information.
  • The state either approves or disapproves carrier
    participation in this states e-screening
    program. The E-Screening Enrollment system is
    the authoritative source for the state acceptance
    decision. E-Screening Enrollment system
    transmits the states decision to CVIEW via a
    carrier snapshot update (TS 285).

  • Step 6 The Enrollment Agent State CVIEW sends
    carrier and vehicle snapshots (TS 285) to the
    Roadside Operations computer. Snapshots are used
    at the roadside when making the bypass/pull-in
    decision.
  • Step 7 Enrollment Agent State CVIEW passes the
    carrier and vehicle segment updates (TS 285) to
    SAFER. These updates include the participation
    request data and Enrollment Agent State
    acceptance decision.
  • Step 8 SAFER subscription process distributes
    the carrier and vehicle snapshots (TS 285) to the
    Additional E-Screening State CVIEWs. Transponder
    ID information is passed only to states where
    carrier has requested participation.
  • Step 9 Additional E-Screening State CVIEW
    subscription processing forwards the carrier
    snapshot (TS 285) to the E-Screening Enrollment
    system
  • Step 10 Additional E-Screening State Enrollment
    system processes the request and either approves
    or disapproves carrier participation.
    E-Screening Enrollment system transmits the
    states decision to CVIEW via a carrier snapshot
    update (TS 285).

  • Step 11 Additional E-Screening State CVIEW
    sends carrier and vehicle snapshots (TS 285) to
    the Roadside Operations computer. Snapshots are
    used at the roadside when making the
    bypass/pull-in decision.
  • Step 12 Additional E-Screening State CVIEW
    passes the carrier and vehicle segment updates
    (TS 285) to SAFER. These updates contain the
    acceptance decisions.
  • Step 13 SAFER subscription process distributes
    the carrier and vehicle snapshots (TS 285) to
    Enrollment Agent State CVIEW.
  • Step 14 Enrollment Agent State CVIEW passes
    carrier and vehicle snapshots (TS 285) to CI.
  • Step 15 Enrollment Agent State CI passes
    acceptance status to CAT via TS 286. Multiple TS
    286 messages may be transmitted at various times
    as each state modifies its acceptance decision.
