Indicates the batch query capability. The capability is in the TLV format. The format of the TLV is shown in the following figure. | TOTAL-LENGTH | TLV-TYPE | TLV-LENGTH | TLV-VALUE | | TLV-TYPE | TLV-LENGTH | TLV-VALUE | | ................................. | | | TLV-TYPE | TLV-LENGTH | TLV-VALUE | TOTAL-LENGTH occupies two bytes to store the whole length of all the TLV, including TOTAL-LENGTH itself. TLV-TYPE occupies two bytes to store the TLV type. TLV-LENGTH occupies two bytes to store the TLV length, which indicates the bytes TLV-VALUE occupies. TLV-VALUE is the content of the TLV. Assume that the ONT supported-capability is 00.17.00.00.00.04.00.00.00.3F.00.01.00.04.01.00.01.01.00.02.00.01.00. The capability description is as follows: | TLV total length | | 00.17 | | TLV1 type | TLV1 length | TLV1 value | | 00.00 | 00.04 | 00.00.00.3F | | TLV2 type | TLV2 length | TLV2 value | | 00.01 | 00.04 | 01.00.01.01 | | TLV3 type | TLV3 length | TLV3 value | | 00.02 | 00.01 | 00 | TLV total length: 00.17: the total length of the TLV is 23 Bytes. TLV1: 00.00: it is the field submask supported by the batch query. 00.04: the length of the TLV1 value is 4 Bytes. 00.00.00.3F: this value indicates that the supported fields are 0, 1, 2, 3, 4, and 5. TLV2: 00.01: it is the TLV type list supported by the batch query. 00.04: the length of the TLV2 value is 4 Bytes. 01.00.01.01: this value indicates that values 256 and 257 are supported. TLV3: 00.02: it indicates whether the batch query to be delayed. 00.01: the length of the TLV3 value is 1 Bytes. 00: it indicates that the batch query does not need to be delayed.
