.1.3.6.1.4.1.4491.2.1.5.1.3.2.1.4
Object
Indicates the Maximum Scheduled Codes Power Headroom in use by the CM, in units of tenth dB. The value is provided by the CMTS in units of quarter dB through a TLV value in the RNG-RSP message and is rounded upward for this MIB object to the nearest tenth dB. A value of zero indicates the CMTS provided no Power Headroom.
