Description: Manages T1/DS1 interface configuration and performance monitoring on ADTRAN ATLAS multiservice access devices.

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 ADTRAN-ATLAS-T1-MIB?

ADTRAN-ATLAS-T1-MIB is a vendor-specific MIB from ADTRAN for T1/DS1 interface management on the ATLAS multiservice access platform used in carrier and enterprise WAN access. It exposes per-slot, per-port T1 interface configuration and status data, including alarm conditions, signal levels, and loss-of-frame error counters. It is used heavily for monitoring the hardware line status of T1 interface cards -- specifically alarm status, receive signal level, and current/total loss-of-frame count (LOFC) events that indicate a failing physical circuit or faulty interface card. It parallels standard IETF DS1/E1 MIB concepts but is implemented as an ADTRAN enterprise extension rather than the RFC-based MIB itself. It is typically deployed by telecom/ISP NOC teams monitoring T1 circuit health on ADTRAN ATLAS access devices at customer premises or POPs. Engineers can download the ADTRAN-ATLAS-T1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ADTRAN-ATLAS-T1-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.

Monitoring Examples

An administrator polls adATLAST1IfTable (indexed by adATLAST1IfSlotNum and adATLAST1IfPortNum) to check adATLAST1IfAlarmStatus and adATLAST1IfRxLevel for each T1 port. A spike in adATLAST1IfCurrentLOFC combined with a degraded adATLAST1IfRxLevel would indicate a failing T1 line or connector issue, while adATLAST1IfTotalLOFC gives a cumulative view for trend analysis. adATLAST1IfResetPRMStats lets an operator clear performance registers after remediation to start a fresh monitoring interval.

What Can Be Monitored

T1 alarm status
receive signal level
current loss-of-frame count
total loss-of-frame count
slot/port interface index
performance statistics reset
