1

(PHT) WiFi RSSI Fail

< -70 dBm RSSI Range at Xi5/Xi6

2

the level a device is transmitting at, or would need to transmit at in order to reach the CMTS at the proper input level

Actual US Tx

3

(PHT)Downstream Receive upper fail

>13 dBmV

4

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

Missing PHY Rate

5

(PHT)Lower fail for Actual upstream transmit

< 25 dBmV

6

(PHT)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.

mocaInterfaceFault

7

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

Incomplete DP3 Data

8

PHT pause is this amount of time

90 seconds(We will use the latest time stamp from JSON

9

What are the five new ICFR location indicators in v5 of PHT

Solo,Outlet,Home,Drop, and Network

10

(PHT) what is a passing RSSI level

Greater Than or Equal To -70 dBm

11

(PHT)FLUX ICFR single threshold fail

>= 3 dB ICFR (non-network issue)

12

(FBC)

Full Band Capture

13

Name this PHT Analysis Type: Possible Noise filter blocking one of the upstreams from connecting

Filter

14

(PHT)EPON Upstream Upper fail

> - 4.0 dBm (no longer a pass/fail)

15

(PHT) all devices in home are passing all threshold specifications.

Pass (Pure Pass)

16

(PHT) with UET 64QAM Max transmit level 2 channel bonded

57 dBmV

17

Name this PHT Analysis Type: The CM Us SNR on a tested device is more tha 5 dB lower than the port level Us SNR

SNR Delta

18

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

mocaUnknownReason

19

4 ways to access customer in PHT

MAC Address, Home Address, Account #, Phone #

20

Name this PHT Analysis Type: All devices offline and matching outage in NWT

Outage

21

these are the MoCa enhancements in PHT

Segmented Network, Bridged Network, and Expected Devices

22

Name this PHT Analysis Type: Device is on a CMTS that does not match the billing node

True Node

23

(PHT)Upper fail for Actual upstream transmit

> 54 dBmV

24

Name this PHT Analysis Type: The CMTS and/or Us interfaces being used by devices on the tested acct do not match a billing or NCP error

True Node

25

What's an Unrecognizable device PHT pass with warning examples

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

26

(PHT) what is a failing RSSI level

Less Than -70 dBm

27

UET

Upstream Extended Transmit

28

(PHT) Partial bonding registration state fail

<4>

29

When an ICFR fault is isolated to a common point in the network that feeds multiple accounts. At least one other neighbor account has an ICFR signature match

network

30

(PHT)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.
