| Description | A table of CMTS operation entries to instruct cable modems
to move to a new downstream and/or upstream channel.
An entry in this table is an operation that has been
initiated from CMTS to generates downstream frequency and/or
upstream channel override fields in the RNG-RSP message sent
to a cable modem. A RNG-RSP message is sent to a cable
modem during initial maintenance opportunity.
This operation causes the uBR to place an entry for the
cable modem specified into the override request queue. The
link is then broken by deleting the modem from its polling
list. When the modem attempts initial ranging, the override
request causes downstream frequency and upstream channel
override fields to be inserted into the RNG-RSP message. |
