Description: Manages discrete I/O signal configuration and state monitoring on AI-series Serial Line Card modules.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is AISLCDISCRETE-MIB?

AISLCDISCRETE-MIB is a vendor-specific MIB from Applied Innovation Inc. that models discrete (binary) input and output points on AI-series Serial Line Card (SLC) modules used in telecom environmental/alarm monitoring systems such as the AIscout and AIscout2 product lines. Its aiSLCDiscreteInputTable exposes each configured input point's normal-versus-alarm state mapping (aislcdinNormalInput, aislcdinAlarmSeverity), current reading (aislcdinCurrentInput, aislcdinCurrentState), TL1 access identifiers for craft-interface integration, and debounce timing, while the companion aiSLCDiscreteOutputTable models controllable relay outputs with energize/de-energize state, momentary timeout behavior, and a boolean aislcdoutEnergizeExpression that can drive an output from combinations of other discrete or analog inputs. A separate set of scalar objects — aislcdiscPowerSupplyStatus, aislcdiscFanStatus, aislcdiscFiber1/2TransmitterStatus, aislcdiscAnalogInputPowerSupplyStatus — reports the SLC card's own internal hardware health. This makes it a dual-purpose MIB covering both external alarm-point monitoring (door contacts, generator status, etc.) and the SLC card's own power/fan/fiber-transmitter condition. The AISLCDISCRETE-MIB MIB is deployed on Applied Innovation SLC-based remote telemetry units in central-office and cell-site environmental monitoring.

IPNetwork Monitor allows you to monitor SNMP objects defined in AISLCDISCRETE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Applied Innovation AIscout/AIscout2 Serial Line Card (SLC) remote telemetry units

Monitoring Examples

An operator polls aislcdinCurrentState across the aiSLCDiscreteInputTable to find any point reporting critical or major, then reads aislcdinCurrentStateText for a human-readable description of that alarm; a critical aislcdinCurrentState on a point whose aislcdintl1AlarmType indicates an environmental condition would flag something like an open door or high-temperature alarm at a remote site.

What Can Be Monitored

discrete input point current state/alarm severity
discrete output point energize/de-energize state
TL1 access identifiers per point
SLC card power supply/fan/fiber-transmitter status
debounce and momentary-timeout configuration

How to Use in IPNetwork Monitor

Example using aislcdiscPowerSupplyStatus OID:

Select an Applied Innovation AIscout/AIscout2 remote telemetry unit (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type aislcdiscPowerSupplyStatus into the Find box to locate it in the OID tree, then select it and click OK. Status of the power supply. okay(1) or trouble(2). On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'okay', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.

STR aislcdoutEnergizeExpression	1.3.6.1.4.1.539.24.2.1.17	DisplayString	read-write	String that describes when this output goes into the energized state, as a function of a discrete input (or analog input for AIscout2). For AIscout, an integer >= 1 represents a discrete input, and '~' complements the input state. For AIscout2, this expression is a combination of analog and discrete inputs. Analog inputs are preceded by an 'A' and discrete inputs by a 'D'. The complement '~' works on a group of inputs. Also, multiple inputs may be specified as a comma separated list (1,3,5) or a hyphenated range (1-5). The expression is a combination of up to three ORs and as many ANDs as desired (i.e. a sum of 3 products). An empty string indicates manual control of the output point. AIscout examples: '15' -- energize the output when input 15 is alarmed (and deenergize when the input is normal). '~8' -- energize the output when input 8 is normal (and deenergize when the input is alarmed). AIscout2 examples: 'AH1,3,5' -- energize if the high alarm is active on analog inputs 1, 3 and 5. '~AH1-2&AL3' -- energize if analog inputs 1 and 2 are normal (not in the alarm state) AND analog input 3 is in the low alarm state. 'AH\|AL\|D*' -- energize if ANY analog is alarmed OR any discrete input is alarmed.
STR aislcdoutLastChangeTime	1.3.6.1.4.1.539.24.2.1.14	DisplayString	read-only	Textual representation of the time of the most recent output change. 24-hour format: YYYY-MM-DD HH:MM:SS.
INT aislcdoutMomentaryTimeout	1.3.6.1.4.1.539.24.2.1.5	INTEGER	read-write	If zero, the output will stay in the alarm state until it is returned to the normal state by some other event. If nonzero, this defines the time interval for momentary operation described in aislcdoutOutput. Maximum is 99.9 seconds.
STR aislcdoutNonAlarmStateText	1.3.6.1.4.1.539.24.2.1.11	DisplayString	read-write	Textual description of the point's non-alarm state. Maximum length is 80 characters.
INT aislcdoutNormalOutput	1.3.6.1.4.1.539.24.2.1.4	INTEGER	not-accessible	DEPRECATED: use aislcdoutAlarmStateOutput.
INT aislcdoutOutput	1.3.6.1.4.1.539.24.2.1.13	INTEGER	read-write	On a read operation, this is the current output of the point. On a write operation when the output is controlled by aislcdoutEnergizeExpression, the write is rejected. Otherwise on a write operation, when set to de-energized, the output immediately assumes this state. When set to energized, the state of the output goes to the energized state, unless the output is already waiting for its aislcdoutMomentaryTimeout interval to elapse.
INT aislcdoutOutputEnable	1.3.6.1.4.1.539.24.2.1.3	INTEGER	read-write	Enable or disable this point. When the point is disabled, the output is immediately de-energized and remains so regardless of the values of other objects in this row. When the point is enabled, output is immediately set to its non-alarm state and operates according to the values of the other objects in this row.
NUM aislcdoutPointNumber	1.3.6.1.4.1.539.24.2.1.1	PositiveInteger	read-only	Output point number to which this table row applies.
STR aislcdouttl1AccessID	1.3.6.1.4.1.539.24.2.1.7	DisplayString	read-write	Unique TL1 access identifier for this point. Maximum length is 22 characters.
INT aislcdoutTrapEnable	1.3.6.1.4.1.539.24.2.1.8	INTEGER	read-write	Enable or disable traps. If enabled, a trap is sent whenever the point changes state.
