x. Error type 3999 indicates that the c ircuit pack sent a larg e number of
control channel messages to the s witch within a short period of time. If
error type 1538 is also present, then the c ircuit pack was taken
out-of-service due to hype ractivity. If error type 1538 is not present, then
the circuit pac k has not been taken out-of-service, b ut it has generated
50% of the messages necessary to be considered hy peractive. This may
be completely normal during heavy traffic p eriods. However, if this error
type is logged when the circuit pac k is being lightly used , it may indicate a
problem with the circui t pack or the equip ment attached to it.
