Operational status identification system for a modem or other communication system
First Claim
1. In a bi-directional communication system performing a sequence of operations including groups of one or more individual operations having an associated status indication, a method for capturing indication of system status, comprising the steps of:
- generating ordered status indications reflecting the status of completion of sequentially performed groups of operations wherein individual status indications are associated with corresponding groups of operations;
capturing said generated status indications;
retaining said captured status indications following initiation of repetition of said groups of operations; and
providing said retained captured status indications as identification of an attained operational status of said system for system operation diagnosis, wherein said groups of operations include at least two different operations from operations including (a) tuning, (b) ranging, (c) configuring, and (d) registering.

Abstract
Processing functions in a communication device are partitioned into a sequence of operational levels having corresponding status indications which are captured prior to a fault or other abnormal condition and retained during re-cycling of the sequence of operations for use in status monitoring or fault diagnosis. In a modem performing a sequence of operations including groups of one or more individual operations having an associated status indication, a method is used for capturing an indication of system status. The method involves generating hierarchically ordered status indications reflecting the status of completion of sequentially performed groups of operations in which individual status indications are associated with corresponding groups of operations. The generated status indications are captured and retained following initiation of repetition of the groups of operations and are provided as identification of an attained operational status of the system for operation diagnosis (e.g., by display using LEDs).
