cadIfMacDomainDownChannelMinFrequency
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadIfMacDomainDownChannelMinFrequency
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.4.2.1.39
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description:
This object is used to configure the C4 CMTS to accept minimum downstream frequency limit that conform with the EuroDOCSIS specifications (starndard range 112 MHz to 858 MHz), (extended 85 MHz to 999MHz) or to the DOCSIS specifications (standard 91 to 867 MHz), (extended range 57 MHz to 999 MHz). Changes to downstream frequency and width are verified against this object to ensure the C4 CMTS does not exceed the downstream spectrum limits imposed by this object. Attempting to increase the minimum downstream frequency limit implied by this object will fail if at least a single downstream is configured outside of the range for the new value. It is recommended this object be set during initial system setup.
What is cadIfMacDomainDownChannelMinFrequency?
This configuration parameter sets the minimum downstream frequency that the CMTS will accept, allowing compliance with EuroDOCSIS or DOCSIS standards depending on the device region. Cable operators use this to enforce frequency constraints appropriate for their market while ensuring interoperability with customer equipment. The range varies between standards (e.g., 85–999 MHz for EuroDOCSIS extended, 57–999 MHz for DOCSIS extended).
