Description: Manages VDSL line provisioning, attainable rates, band plan, and performance monitoring on the Ericsson Diax IP DSLAM.

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 PEA-VDSL-IPDSLAM?

PEA-VDSL-IPDSLAM is an Ericsson Diax IP DSLAM proprietary MIB for managing VDSL/VDSL2 line pairs, covering line provisioning, attainable bit rates, band plan and PSD limiting masks, and performance monitoring, filling a gap left by the general ADSL-LINE-MIB before a dedicated ADSL2/VDSL2 IETF MIB existed. It exposes upstream and downstream PSD limiting-mask tables with break-point definitions, plus VDSL2 status and profile/channel objects. It is used to monitor the software configuration and operational status of VDSL2 lines, including which spectral mask and channel profile is applied and the resulting line status, which helps identify misconfigured masks or profile mismatches that degrade attainable line rates rather than exposing chassis-level hardware sensors. It explicitly builds on and supplements the IETF ADSL-LINE-MIB (RFC 2662/RFC 3440) and the vendor's own PEA-ADSL-IPDSLAM module. It is deployed on Ericsson Diax IP DSLAM platforms delivering VDSL2 broadband access to subscribers. Engineers can download the PEA-VDSL-IPDSLAM file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PEA-VDSL-IPDSLAM. 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

  • Ericsson Diax IP DSLAM
  • VDSL/VDSL2 access equipment

Monitoring Examples

An engineer would inspect vdslLineConfPhysVdslLimitingMaskDnTable/Entry and the corresponding Up table, checking limitingMaskDnBpToneIndex and limitingMaskDnBpPsd break points against the provisioned band plan to confirm the correct PSD mask is enforced per line. Polling vdsl2Status alongside vdsl2ProfileChannel reveals the active VDSL2 profile and current line state, useful for diagnosing lower-than-expected attainable rates. A mismatch between limitingMaskDnBypassOutbandPsdFilter settings and expected regulatory limits could explain interference complaints from a subscriber.

What Can Be Monitored

  • VDSL2 line status
  • PSD limiting mask break points (up/down)
  • VDSL2 profile/channel selection
  • band plan / outband PSD filter settings
