4 SETUP AND OPERATION ICE Program Configuration
The ICE Program Configuration window is available in any Internal SEM Device Operating Mode. This window is used to enable or disable Common Tier Encryption, as well as to define the encryption settings. Any change to these parameters will cause a momentary loss of service on all SEM outputs. This is due to the fact that all programs mapped are unmapped and re-mapped to perform the CTE change. The ICE Program Configuration window is illustrated in Figure 4-63 and defined in Table 4-47.

Item Definition
Common Tier Encryption Enabled Enable, or disable, Common Tier Encryption. If CTE is disabled, all other settings in this window will be grayed out. CTE cannot be enabled unless the SEM has been licensed for CTE and the ACP module is present.
Configured Encryption Mode Set the global encryption mode that the SEM will attempt to use to encrypt output
programs. Default value is “Clear.”
• Clear — The SEM performs no encryption of output programs.
• Fixed Program Key — The SEM attempts to use Fixed Program Key encryption. The SEM will not attempt to get Entitlement Management Messages.
• Full — The SEM attempts to use Full encryption. The SEM will attempt to get Entitlement Management Messages from an EMM server.
Current Encryption Mode Encryption mode that the SEM is actually using to encrypt output programs. The current encryption mode is based on the Configured Encryption Mode setting and the status of the ACPs. The Current Encryption Mode can differ from the Configured Encryption Mode if all requirements for the Configured Encryption Mode are not met.
• Clear — The SEM is considered to be in Clear mode when Configured Encryption Mode is set to “Clear.”
• Fixed Program Key — The SEM is considered to be in Fixed Program Key mode when Configured Encryption Mode is set to “Fixed Program Key,” or when Configured Encryption Mode is set to “Full”
and the status of one or more ACPs indicates that full encryption is not available.
• Full — The SEM is considered to be in Full encryption mode when Configured Encryption Mode is set to “Full” and the status of all ACPs indicate that full encryption is available.

SEM VOD Control — ICE EMM Configuration
The SEM VOD Control — ICE EMM Configuration window provides the capability to specify the EMM server polling and startup randomization period, as well as the polling timeout and retry count. It provides the capability to specify the EMM Server IP Address and Port and the EMM Server
Communication Timeout. Additionally, it provides the capability to set default ICE EMM configuration values and to initiate an EMM rollover sequence. The SEM only needs to communicate with an EMMS when it is in Full Encryption mode. The ICE EMM configuration parameters are not applicable unless the SEM is configured to be in Full Encryption mode. The ICE EMM Configuration window is illustrated in Figure 4-65 and defined in Table 4-49.

Item Definition
EMM Polling Interval (minutes) The SEM polls the EMM server for a category sequence number (CSN) and a state as often as this field specifies. The polling interval can range from 15 to 1440 minutes. After receiving the CSN and state, the SEM will determine if it needs to request new EMMs from the EMM server. If the SEM is unable to communicate with the EMM server, the SEM will revert to a 15 minute polling period interval until
communication with the EMM server is re-established.
EMM Polling Randomization Interval
(minutes) Maximum amount of time, in minutes, to delay the first EMM server poll following startup.
This prevents the possibility of having too many SEMs polling the EMM server
simultaneously. The actual delay time will be randomly calculated by the SEM and will be no greater than this value, which can range from 0 to 10 minutes. A value of 0 means no delay and the SEM will poll immediately at startup.
Note that when the SEM is first booted, CTE is enabled, and the Encryption mode is set to Full, the SEM will not be able to go to full encryption until after the SEM establishes communication with the EMMS. This will not occur until after this polling randomization time has expired. This can cause the SEM to take up to 10 minutes before going to Full
encryption. Setting this value to 0 will force the SEM to immediately poll the EMMS upon booting.
EMM Polling Timeout (seconds) Amount of time, in seconds, that the SEM will wait for a poll response from the EMM server.
If a response is not received within the designated timeout period the SEM will retry the poll.
EMM Polling Retry Count The number of times that the SEM will attempt to retry a timed out EMM server poll. An EMMS Invalid Response or EMMS
Communications Failure alarm will be issued after the last retry.
EMM Server IP Address Class A, B, or C IP address of the EMM server.
EMM Server Port EMM server TCP Port 0 to 65535. Default is 8080 (standard DAC 6000 EMM Server port number).
EMM Server Communication Timeout
(Days) This is the amount of time, in days, that the SEM will keep all programs in full encryption mode after communication with the EMM

encryption mode upon expiration of this time period. The duration start time is based on the time when the SEM was last able to
successfully communicate with the EMMS.
Set Defaults Configures all ICE EMM Configuration parameters to factory-default values. The Server IP and UDP port are not reset to their default values.
Force EMM Rollover Forces the SEM to retrieve new EMMs (rollover sequence).
SEM VOD Control — ICE EMM Status
The SEM VOD Control — ICE EMM Status window provides a table of the most recent EMM server polls. It displays the current CSN in use, the time remaining before the next EMM server poll, the time remaining until expiration of full encryption, and the last time an EMM rollover occurred. It presents counts of communications errors, invalid responses, and encryption failures, as well as various alarms and buttons for resetting and clearing. This window is only valid when the SEM is configured to be in Full Encryption mode. It is illustrated in Figure 4-66 and defined in Table 4-50.

Item Definition
GPS Time GPS time of the state transition.
CSN EMM server Category Sequence Number
(CSN).
State The state of the EMM transition. Indicates
EMM transition state reported by the EMMS.
Transition Complete, Transition Start, or Start of New Epoch.
ACP Address This is the address of the Access Control Processor (ACP) associated with the error reported by the EMM server in the EMMS Error column. If no address is contained in this entry, the error reported applies to all ACPs or to the entire SEM.
EMMS Error See below.
Current CSN In Use (0-255) This is the current Category Sequence Number (CSN) that the SEM is using for encrypting all programs. When the last poll indicates that the EMM server is starting or that it has completed a category epoch transition, the current CSN in use is one larger than the last CSN reported by the EMM server. Otherwise, the current CSN in use is equal to the last CSN reported by the EMM server.
Time Before Next EMM Poll (days
hh:mm:ss) Time remaining until the next EMM poll.
Full Encryption Expiration Time (days
hh:mm:ss) Amount of time remaining before the SEM will automatically revert from Full encryption to Fixed Program Key (FPK) mode. This occurs as a result of a communication error or an invalid response from the EMM server. The amount of time is based on the user-configurable EMM Server Communication Timeout and when the SEM last successfully received EMMs (See Table 4-46).
If this box is Magenta, it indicates that the SEM has already gone from Full Encryption mode to FPK mode (error). The time indicates how long the SEM has been out of Full Encryption mode. This can be used to determine the time when the SEM went into FPK mode due to an error.
Last Time EMM Rollover Performed (GPS) The time in GPS when the SEM last
performed a successful EMM rollover request since bootup. The time is when the SEM started the EMM rollover request.

Item Definition
Number EMMS Communication Errors The number of times that the SEM was unable to establish communications with the EMM server. A communication is considered to be in error after all user configurable EMM Polling Retry Counts have been exhausted (See Table 4-46). This count can be reset via the adjacent Reset Counts button.
Number EMMS Invalid Responses The number of invalid responses received from an EMM server. This count can be reset via the adjacent Reset Counts button.
EMMS Communication Failure Alarm This alarm is set whenever the SEM is unable to communicate with the EMM server. This alarm is cleared whenever communication is re-established, the SEM mode is configured to Clear or FPK, or the user manually clears the alarm.
EMMS Invalid Response Alarm Set whenever the SEM receives an invalid response from the EMM server. This alarm is cleared whenever a valid response is received, the SEM mode is configured to Clear or FPK, or the user manually clears the alarm.
SEM ICE Full Encryption Failure Count A count of the number of times the SEM alarmed due to a full encryption error.
SEM ICE Full Encryption Failure Alarm Indicates that even though the SEM is configured to be in full encryption, it can not be due to EMM server communications or invalid response errors. The alarm will clear when the SEM returns to full encryption.
Reset Counts Reset both EMM server Communication
Failure and Invalid Response counters to 0.
Clear Alarm (EMM Server Communications
Failure) Clear any alarms caused by the failure to poll the EMM server.
Clear Alarm (EMM Server Invalid Response) Clear any alarms caused by the reception of invalid EMM server responses.
