Q

PHT results fall into 4 possible results:

A

Pass• Pass W/ Warnings • Pass W/Overrides • FAIL

22
Q

What’s an Unrecognizable device (PHT) PHT pass with warning examples

A

active device on an account (account at least 3 days old) that has been unresponsive for longer than 24 hours

23
Q

Unrecognizable Device, Incomplete D3P Data, Service Call Failure, Missing PHY Rate are override examples for

A

PASS W/ WARNINGS

24
Q

CMTS knows the device has been online within the prior 24 hours but device is offline

A

Unresponsive Device

25
Q

Poll for data is missing data (could result from poor cell connectivity or disruption during test)

A

Incomplete DP3 Data

26
Q

Failure to call data sources (cell connectivity, VPN drop, tools outage)

A

Service Call Failure

27
Q

Call from X-Ray failed to return PHY rates for all devices

A

Missing PHY Rate

28
Q

US Tx, Ds SNR, Ds RX, spectra suckout, spectra wave are override examples for

A

PHT Pass w/override

29
Q

filter, outage, poe filter, snr delta, true node are what

A

PHT analysis types

30
Q

Downstream RX upper fail

A

> 13 dBmV

31
Q

Downstream SNR single threshold fail

A

<33dB

32
Q

MoCA PHY Rate single threshold fail

A

< 200 Mbps (Xi to Xi rates excluded)

33
Q

FLUX ICFR single threshold fail

A

> = 3 dB ICFR (non-network issue)

34
Q

Downstream RX lower fail

A

< -13 dBmV

35
Q

4 ways to access customer in PHT

A

MAC Address, Home Address, Account #, Phone #

36
Q

EPON Us Rx upper fail

A

>

  • 4.0 dBm
37
Q

EPON Ds Rx lower fail

A

< -28.5dBm

38
Q

EPON Us Rx lower fail

A

< -28.0 dBm

39
Q

EPON Ds Rx upper fail

A

> -8.0 dBm

40
Q

SpectraCM impairments single threshold fail

A

Any Individual Impairment <>ACP (suckout and wave only)

41
Q

FM ingress poller single threshold fail

A

severe FM ingress

42
Q

MoCA bridged network single threshold fail

A

device from another account on MoCA network

43
Q

MoCA segmented network single threshold fail

A

multiple separate MoCA networks on account

44
Q

This means that there is only one device with a MoCA interface assigned to the target account, so it is not of concern that it is by itself with no other nodes to talk to

A

singleExpected

45
Q

This means that the MoCA interface of this device has been disabled, typically something that is only done by Field Operations or Customer Care personnel. The device is not part of a MoCA network by design.

A

mocaDisabled

46
Q

This means that the device responds via DOCSIS interrogation, but either doesn’t appear on the MoCA network or is by itself on a segment separate from other devices.

A

possiblePhysicalImpairment

47
Q

This is a serious issue as the device is powered up and on plant, indicating the customer’s intent to use it, but it is not talking to other MoCA-capable device in the home. This will usually accompany a split network indication

A

possiblePhysicalImpairment

48
Q

This means the device is not responding via DOCSIS or MoCA and therefore there is not a way to determine its current state.

A

deviceNotResponding

49
Q

This indicates one of a number of unusual states defined in the TR-181 spec that Xi STBs and XB wireless gateways can enter. We don’t believe that the RDK teams have implemented setting the MoCA status to one of these states, but it is for future-proofing in case they do.

A

mocaInterfaceFault

50
Q

This indicates that MoCA is reporting what appears to be illegal states or other behaviors that don’t have a clear root cause.

A

mocaUnknownReason

51
Q

singleExpected, mocaDisabled, possiblePhysicalImpairment, deviceNotResponding, mocaInterfaceFault, mocaUnknownReason refer to what?

A

MoCA Isolated Device Analysis
