5.5.1 Introduction
The purpose of the Carrier ID Reader/Writer functional standard is to
provide a common specification for concepts, behavior, and services
provided by a Carrier ID Reader/Writer to an upstream controller. A
standard interface will increase the interchangeability of a Carrier ID
Reader/Writer, so that users and equipment suppliers have a wide
range of choice.
Scope:
1. The interface standard addresses the functional requirements for
a generic Carrier ID Reader/Writer interface with an upstream
controller.
2. The specification includes the required behavior and required
communications for a Carrier ID Reader and Writer.
3. The specification does not require, define or prohibit
asynchronous messages sent by the Carrier ID Reader or Writer.
4. This standard does not purport to address safety issues, if any,
associated with its use.
5.5.2 State Models
To facilitate independent control of the individual heads, there are two
separate state models defined, one for CIDRW subsystem and one for
each individual head. The LDN reader combines the CIDRW
subsystem with the head.
The state model for the BROOKS reader is displayed in the state model
below.
