6 .6 UCrypt EAS Event
6 .6 .1 Refers to
Reception of an event related to the Emergency Alert System (EAS)
. Each EAS event will be reported as an alert without
details as to the specific nature of the EAS event. An official test of the EAS system will be reported with the same alert as a
real EAS event.
6 .6 .2 Repetition of Alert
Alert is sent only once per EAS event. No further notification is generated.
6 .6 .3 Customer Symptoms
Customer experiences loss of regular programming for duration of EAS event. Customer may receive substitute programming
consisting of force tune Details Channel or text message for the duration of the event.
6 .6 .4 Urgency
Informational purposes only.
6 .6 .5 Cases Where Alert is Likely a Result of:
Outside influence or normal operation
This alert is generated when the EAS event is received via the OOB carrier or Inband if applicable. Expect this alert to be sent
with every test of the EAS system.
An Internal Issue
There are no internal issues that will cause this alert.
6 .6 .6 Probable Causes
1. An EAS event message has been received.
6 .6 .7 Next Steps
1. There is no need for any action to be taken for this alert. The alert is informational only.
6 .7 UCrypt Channel Map Update Exception
6 .7 .1 Refers to
The inability of the UCrypt to accommodate a program move as required by a channel map update
. The Channel Map
is also known as the Virtual Channel Table and is transmitted by the Cable Service Provider on the OOB carrier to inform the
system STBs of the current location of each program carried on the cable system. This relates the “Cable Channel” to the EIA
QAM channel and MPEG program number (the EIA Major and Minor Channel Numbers) of each service. The Channel Map
is sent from time to time to reflect the moving of programs to different QAM channels etc. This alert will be sent if there are
no available tuners to acquire a QAM channel if the QAM channel was not previously being received. This will be a very rare
event most likely to happen on a UCrypt where all available tuners must be used to process the desired programs and at least
one tuner is processing multiple programs.
6 .7 .2 Repetition of Alert
Alert is sent once when a ‘program follow’ is not able to be accommodated. No further notification is generated until the issue
is rectified and another instance of ‘failure to follow’ a program due to insufficient resources occurs again.
6 .7 .3 Customer Symptoms
Customer experiences loss of the program affected by the alert as there is no available tuner for the program. All remaining
programming is unaffected.
6 .7 .4 Urgency
Critical.
6 .7 .5 Cases Where Alert is Likely a Result of:
Outside influence or normal operation
This alert is generated when the Channel Map Update is received and there are not enough tuners to receive the required
number of QAM channels. This further indicates that a previously tuned and received program was lost due to insufficient
