VII. IMACS System Testing and Diagnostics

IMACS System Parameters

System level parameters that are supported include a user-defined node name called the node ID. It can be up to 14 alphanumeric characters long without spaces and four password-protected access levels that correspond to different access and capability levels. Additionally, the IMACS allows users to customize alarm management functions to their requirements.

Password Protection

The four access levels that are available to users are: “super-user,” “manager,” “operator,” and “viewer”. The highest is “super user” which allows flash download of software, full access to all configuration options, diagnostic features, and password management. The “operator” access level allows read and write access to all configuration and diagnostic functions and the “viewer” access level, which is the lowest, allows read-only access to system status and configuration options.

All four access levels are protected by user-defined passwords. Passwords can be up to 12 alphanumeric characters and are case-sensitive. The ability to change passwords is hierarchical in that someone logging in at a certain access level may change the passwords associated with their own level and the passwords associated with lower access levels. For example, “super user” may change the passwords associated with all four levels. Similarly, “operator” may change the password associated with both the “operator” and the “viewer” levels only.

Port Status Summary

The IMACS supports the ability to display a summary of the status of each port on every card installed in the system. This information is displayed in the main menu screen next to the card type field associated with each slot. The user has the option of turning this information on or off with a single keystroke by pressing the “s” key. All loop backs that are commanded from the user interface will be represented on the main screen. In addition to the Out-Of-Service (OOS) and Reject (REJ) messages that are associated with the status of the entire card, the system will describe the status of each port by displaying one of the following letters:

Letter Meaning

“a”	Port is active
“s”	Port is in standby mode
“l”	Port is in loop back
“t”	Port is in test mode
“r”	Port is the redundant mate of an active port
	(Applies to WAN ports and ADPCM card)
