ITU-T G.988 (2012)/Amd.1 (05/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecom

13、munication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Ass

14、embly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology wh

15、ich fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with

16、this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory la

17、nguage such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this

18、 Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date

19、of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the T

38、ce clause 9.1.14 with the following text: This managed entity models the ONUs ability to enter power conservation modes in cooperation with the OLT in an ITU-T G.987 system. ITU-T G.987.3 originally specified two alternative modes, doze and cyclic sleep. The subsequent revision of ITU-T G.987.3 simp

39、lified the specification providing a single power conservation mode, watchful sleep. An ONU that supports power conservation modes automatically creates an instance of this managed entity. 4 Rec. ITU-T G.988 (2012)/Amd.1 (05/2014) Relationships One instance of this managed entity is associated with

40、the ONU managed entity. Attributes Managed entity ID: This attribute uniquely identifies each instance of this managed entity. There is only one instance, number 0. (R) (mandatory) (2 bytes) Power reduction management capability: This attribute declares the ONUs support for managed power conservatio

41、n modes, as defined in ITU-T G.987.3. It is a bit map in which the bit value 0 indicates no support for the specified mode, while the bit value 1 indicates that the ONU does support the specified mode. (R) (mandatory) (1 byte) Codepoints are assigned as follows: Value Meaning 0 No support for power

42、reduction 1 Doze mode supported 2 Cyclic sleep mode supported 3 Both doze and cyclic sleep modes supported 4 Watchful sleep mode supported 5255 Reserved Power reduction management mode: This attribute enables one or more of the ONUs managed power conservation modes. It is a bit map in which the bit

43、value 0 disables the mode, while the value 1 enables the mode. Bit assignments are the same as those of the power reduction management capability attribute. The default value of each bit is 0. (R, W) (mandatory) (1 byte) Itransinit: This attribute is the ONU vendors statement of the complete transce

44、iver initialization time: the worst-case time required for the ONU to regain full functionality when leaving the asleep state in cyclic sleep mode or low power state in watchful sleep mode (i.e., turning on both the receiver and the transmitter and acquiring synchronization to the downstream flow),

45、measured in units of 125-microsecond frames. The value zero indicates that the sleeping ONU can respond to a bandwidth grant without delay. (R) (mandatory) (2 bytes) Itxinit: This attribute is the ONU vendors statement of the transmitter initialization time: the time required for the ONU to regain f

46、ull functionality when leaving the listen state (i.e., turning on the transmitter), measured in units of 125-microsecond frames. The value zero indicates that the dozing ONU can respond to a bandwidth grant without delay. If watchful sleep is enabled, the ONU ignores this attribute. (R) (mandatory)

47、(2 bytes) Maximum sleep interval: The Isleep/Ilowpower attribute specifies the maximum time the ONU spends in its asleep, listen, or low power states, as a count of 125-microsecond frames. Local or remote events may truncate the ONUs sojourn in these states. The default value of this attribute is 0.

48、 (R, W) (mandatory) (4 bytes) Maximum receiver-off interval: The Irxoff attribute specifies the maximum time the OLT can afford to wait from the moment it decides to wake up an ONU in the low Rec.

(R, W) (mandatory) (4 bytes) Minimum aware interval: The Iaware attribute specifies the time the ONU spends in its aware state, as a count of 125-microsecond frames, before it re-enters asleep or listen states. Local or remote events may independently cause the ONU to enter an active state rather than returning to a sleep state. The default value of this attribute is 0.
