cadUpchannelRangingTimingOffset
Module: CADANT-CMTS-UPCHANNEL-MIB
OID (symbolic): CADANT-CMTS-UPCHANNEL-MIB::cadUpchannelRangingTimingOffset
OID (numeric): 1.3.6.1.4.1.4998.1.1.15.3.5.9
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object controls TLV 46.8.2, an offset from the reference channel, to set the Ranging Offset of the burst transmission for the new channel so that bursts arrive at the expected mini-slots time at the CMTS. The units are (1/10.24MHz) = 97.65625 ns. A negative value implies the Ranging Offset is to be decreased, resulting in later times of transmission at the CM. The CMTS MUST include this TLV within the TCC when the Upstream Channel Action is Add or Replace and Initialization Technique has a value of 2, 3 or 4.
What is cadUpchannelRangingTimingOffset?
Configures a timing offset (in units of approximately 97.66 ns) applied during upstream ranging so that burst transmissions arrive at the CMTS at the correct mini-slot time when a modem moves to a new channel. This fine-tuning compensates for propagation delay differences between the reference channel and the new channel.
