This section describes the miscellaneous discrete environmental alarm/status input points and (external) control output points.
The user-settable miscellaneous discrete interface allows users to monitor and control equipment collocated with Alcatel-Lucent 1665 DMX through a set of discrete input and output points. There are 19 miscellaneous discrete inputs to monitor environmental conditions such as open doors or high temperature, and 4 miscellaneous discrete outputs to control equipment such as fans and generators.
Local miscellaneous discrete input points are included in the determination of the summary alarm/status level for each NE. But even if the Remote NE Status feature is enabled, the alarm/status of individual miscellaneous discrete inputs/outputs is not exchanged among NEs.
The alarm level to be associated with each miscellaneous discrete input point is provisionable. By default, each miscellaneous discrete input is a minor alarm.
If a miscellaneous discrete input point is provisioned as an alarm (minor, major, or critical), TL1 autonomous message REPT ALARM EVT is used to report the alarm occurrence. This identifies the remote NE to further query.
If a miscellaneous discrete input point is provisioned as not alarmed (that is, status), TL1 autonomous message REPT EVT CON is used to report the condition. This identifies the need to retrieve any active miscellaneous discrete status conditions.
The description to be associated with each miscellaneous discrete input alarm or status point may be provisioned. The provisioned description appears as the almmsg or conddescr parameter value in applicable TL1 messages. The default description for each miscellaneous discrete input point is environment1, environment2, and so forth.
Note:
Miscellaneous discrete Input Point 15 is reserved for fan failure.
The description to be associated with each miscellaneous discrete output control point may be provisioned. The default description for each miscellaneous discrete output point is control1, control2, and so forth. Control points for miscellaneous discrete outputs may be operated and then released.
Miscellaneous Discrete #15 is reserved for fan failure. The possible alarm levels are CR, MJ, MN, with MJ being the default.
