AT&T DS1/DMi/ISDN-PRI manual Performance

7-70	ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 2
Field 7	Assigns whether hyperactivity management will be enabled for the ISDN-PRI link.
	Hyperactivity is defined as erratic behavior by the D-signaling channel. Typically, a
	hyperactive link will generate an excessive amount of meaningless traffic. Excessive
	D-channel traffic may overload the module processor and degrade system
	performance.

Field encodes and their descriptions are:

–(Dash) not applicable. This would be administered for all ISDN-BRI links.

0 Disables hyperactivity management for the particular ISDN-PRI link (this is the recommended option for SNC links).

1Enables hyperactivity management (recommended for all ISDN-PRI links except SNC links). This software (hyperactivity management) functions to monitor link performance, detect when certain error thresholds have been exceeded, busyout the link on exceeding the threshold, and record the failure reason as FAULT CODE 337 in the maintenance log.
