DOCSIS 3.1 CCAP Operations Support System Interface Specification CCAP-OSSIv3.1-N-15.1390-1 This attribute reports the P1.6hi value for the CM’s Transmit Channel Set This attribute reports the level of the top of the Dynamic Range Window. The value is expressed in dBmV and is the result of a calculation equal to P1.6hi - P1.6load_min_set This attribute is the higher of the CCAP’s minimum supported downstream frequency and the CM’s minimum supported downstream frequency. It indicates the lowest downstream frequency the CCAP can use to communicate with this CM taking into account the capabilities of both devices. This attribute is the lower of the CCAP’s maximum supported downstream frequency and the CM’s maximum supported downstream frequency. It indicates the highest downstream frequency the CCAP can use to communicate with this CM taking into account the capabilities of both devices.
