12
Scope

• This standard defines the protocol for inter-car
  and intra-car serial data communications between
  subsystems aboard passenger trains. It sets
  forth the minimum acceptable parameters for a
  network that can simultaneously handle monitoring
  and control traffic from multiple systems. While
  the network itself is not vital, it is intended
  to be capable of carrying vital messages. This
  standard will be structured with respect to the
  OSI seven-layer model.

13
Purpose

• A standard protocol will permit systems provided
  by a variety of suppliers performing different
  on-board functions to share a common
  communications facility. Car wiring and weight
  will be reduced while systems integration,
  reliability, and maintainability will be improved
