AirCodec  ·  Monitoring

Your NMS sees the codec, not just the PC it runs on.

AirCodec carries a full SNMP v2c agent with its own MIB, built for Broadcast Network Monitor and for any NMS that can load a MIB file. Every codec is a row; everything the window shows an operator, an NMS can poll — and the eighteen things worth waking somebody for are traps.

AirCodec  +  Broadcast Network Monitor

Built for Broadcast Network Monitor

AirCodec and Broadcast Network Monitor are built by the same people, and BNM already knows what an AirCodec is — it is a device type with its own page, its own alert rules and its own history. More to the point, BNM watches the site from outside it. Any other NMS will poll the agent too; this is the one that will wake somebody up.

An AirCodec device page in Broadcast Network Monitor: the device is in a critical state with an open alert, the AirCodec panel shows one codec on air and four listening with the version, engine build, licence, Direct links, relays and relay board status, then a panel per codec with its state, send and return meters, loss, jitter, round trip and bit rates, an audio level history graph for each, and an alerts list at the foot Open full size
One AirCodec, five codecs, on a BNM device page. Codec 1 is on emergency audio with its legal ID library empty — the open critical alert at the foot says exactly that, in words, and it is the alert that dials out.
With BNM

It becomes a device on the board

No MIB wrangling, no OID spreadsheets, no building a dashboard. AirCodec shows up as a device type BNM already has a page for.

  • A page per codec — state, levels, loss, jitter, round trip, rates, all five at once
  • Alerts that know the product — not "OID went non-zero" but emergency audio is on air, the studio link is down
  • Dial-outs and escalation — the same contact rules, schedules and acknowledgement as the rest of the plant
  • History kept beyond the 24 hours the codec holds on disk
  • Work orders raised off an alert, with the device notes attached
Any NMS

Poll it like a transmitter

Nothing proprietary, nothing to license. Point your monitoring system at the agent and it reads everything the operator can see.

  • SNMP v2c, your port and community
  • 73 columns per codec across five rows
  • 18 traps to a destination you set
  • Read only — nothing can be changed over SNMP
  • Save the MIB straight out of the SNMP tab

What an AirCodec alert actually says

Emergency

Codec 1 emergency audio on air — the studio link is down

Compliance

Codec 1 on emergency audio with no legal ID loaded — the station is on the air unidentified

Unreachable

Cannot reach the codec via SNMP

Hardware

Relay board lost — the transmitter contact cannot fire

AirCodec has no mail client, on purpose. A codec that has lost its internet cannot send you an email — the one message you needed most is the one that never leaves the building, and a product that pretends otherwise is selling you a warning that arrives only when nothing is wrong. An alert has to originate somewhere that still has a network, looking in at the site from outside. That is what BNM is for: it notices the silence, because silence is exactly what it is watching for.

Each one resolves itself when the condition clears, and the duration is kept. That second line is the one worth having. A codec quietly running emergency programming with no legal ID loaded is a licence problem that no generic SNMP threshold will ever catch — because nothing is down, nothing is red, and the transmitter is happily modulating.

Poll it like any other device in the plant

The row for a codec is not a cut-down summary. It is the same information the operator is looking at, in a form your monitoring system can trend, alert on and keep.

The SNMP tab of AirCodec settings: a tick box to enable the agent, the agent port and community, an optional trap destination and trap port, a status line showing the agent listening, the enterprise OID and a save MIB file button Open full size
Settings → SNMP. Port, community, an optional trap destination, and a button that writes the MIB file out for your monitoring system. The status line always tells you which port the agent actually got.

On every codec row

  • The link — transport, state, registration, far end, codec and bit rate each way, FEC
  • The path — packet, byte and loss counters, jitter and round trip with their peaks, retransmitted and recovered, link quality
  • The audio — send and return level per channel with an audio-present flag, so a dead channel shows as a dead channel rather than a quiet one
  • The plumbing — ports, loaded connection
  • The list — which phase and which slot, and what is being tested right now
  • Emergency audio — whether it is on and for how long, the cut playing, its kind and position, the next cut, the seconds until the legal ID, and what is loaded
  • The watch — the audio watch and the relay it is holding

Scalars, once per box

  • App version, engine build and protocol level — and whether the engine is stale
  • Licence state
  • Registrar
  • Stream, Barix and Direct summaries
  • The ten contact closures
  • UPnP
  • The USB relay board and the state of its outputs

Eighteen traps

  • Engine exit
  • Registration up
  • Registration down
  • Call up
  • Call down
  • Stream failure
  • Barix failure
  • Direct up
  • Direct down
  • Audio silent
  • Audio restored
  • Stale engine
  • Emergency audio on
  • Emergency audio off
  • List step change
  • Audio watch lost
  • Audio watch restored
  • Relay board found / lost

With Broadcast Network Monitor the codec appears as a device like any transmitter or switch — its own page, its own alert rules, its own history — so a studio-to-transmitter link that has quietly fallen to its second slot shows up on the same board as everything else at that site.
