Description: Indicate if the transmit power extension (after registration) feature is enabled or not on the CMTS. If set to 'true', the CMTS will populate TLV5.40 in the REG-RSP-MP message with the same value received in the REG-REQ-MP message (advertised CM capability). If set to 'false', the CMTS will respond with 0 in TLV5.40 of the REG-RSP-MP message. The value in this MIB object is ignored if MTCM is disabled

What is cadIfMacDomainCmTxPwrExtentionPostRegistrationEnabled?

Controls whether the transmit power extension feature is enabled for cable modems after they have completed registration on this MAC Domain. When set to true, the CMTS echoes back the modem's requested transmit power extension value in the REG-RSP-MP registration response message.
