SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416]. Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (1..255) · OCTET STRING · hint 255t

This object indicates the configured priority of the selected T0 clock. A smaller value represents a higher priority.

TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be defined in the description of any object defined using this type. If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks

SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416].

This object indicates the current clock quality level of the T4 input clock source. This is the effective quality which is derived from three values: 1) most recent clock quality level received, 2) forced clock quality level (entered via configuration) 3) overridden clock quality level as a result of line protocol down, signal failure, or alarms.

Reference: ITU-T standard G.781 section 5.8

This object indicates the hold-off time value of a T4 input clock source. The hold-off time prevents short activation of signal failure is passed to the selection process. When a signal failure event is reported on a clock source, it waits the duration of the hold-off time before declaring signal failure on the clock source.

Reference: ITU-T standard G.781 section 5.9

This object indicates the wait-to-restore time value of a T4 input clock source. The wait-to-restore time ensures that a previous failed synchronization source is only again considered as available by the selection process if it is fault-free for a certain time. When a signal failure condition is cleared on a clock source, it waits the duration of the wait-to-restore time before clearing the signal failure status on the clock source.

This object indicates the forced switching flag. Forced switching, as described in G.781, is used to override the currently selected synchronization source. The 'true' value indicates the currently selected T4 clock source is a result of the forced switching. The 'false' value indicates the currently selected T4 clock source is not a result of forced switching.

TruthValue1 = true2 = falseRepresents a boolean value. · Integer32

Reference: ITU-T standard G.781 section 5.11.2.3

This object indicates the manual switching flag. The 'true' value indicates the currently selected T4 clock source is a result of the manual switching. The switch allows a user to select a synchronization source assuming it is enabled, not locked out, not in signal fail condition, and has a QL better than DNU in QL-enabled mode. A clock source is enabled when it occupies a row in cnsT4ClockSourceTable. A clock source is not locked out when cnsT4ClkSrcLockout contains the value 'false'. A clock source is not in signal failure condition when cnsT4ClkSrcSignalFailure contains the value 'false'. The QL is identified in cnsT4ClkSrcQualityLevel. In QL-enabled mode, a manual switch can be performed only to a source which has the highest available QL.
