What Is TEL2N-MIB?

TEL2N-MIB is a vendor-specific MIB from 2N TELEKOMUNIKACE covering the company's Helios IP intercom product line, exposing device identity and SIP registration state for IP door-entry/intercom units. Under the heliosip subtree it reports hipProductName, hipHwVersion, hipSerial, hipVersion, and hipBootVersion for hardware/firmware identification, and a hipSipTable indexed by hipIndex tracks each configured SIP account's hipPhoneNumber, hipState (down, goingup, up, goingdown), hipRegistrationAt (registrar IP), and hipRegistrationTime. This makes it a compact device-identity-and-SIP-registration MIB rather than a call-detail or access-control MIB, useful for confirming an intercom unit is registered with its SIP proxy/PBX and identifying which registrar it last registered against. It is deployed on 2N Helios IP intercom hardware at building entrances and gates, typically alongside a SIP PBX or intercom management platform. Facilities/telecom teams poll the TEL2N-MIB MIB to confirm door intercom SIP accounts remain registered and reachable.

IPNetwork Monitor allows you to monitor SNMP objects defined in TEL2N-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

  • 2N TELEKOMUNIKACE Helios IP door intercom devices

Monitoring Examples

An operator polls hipState across hipSipTable for every intercom unit at a site; a hipState stuck at down or goingup for longer than the expected registration retry interval would indicate the intercom has lost SIP registration and can no longer receive or place calls.

What Can Be Monitored

  • device product name/hardware/firmware version
  • serial number
  • per-account SIP registration state
  • SIP registrar IP address
  • SIP registration timestamp

How to Use in IPNetwork Monitor

Example using hipState OID:

Select a 2N TELEKOMUNIKACE Helios IP door intercom device (SIP registration/hardware identity status) 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 hipState into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the current state of account. 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 'up', 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.
