Usage Guidelines
This command shows debugging messages about the Upstream Transmitter Disable (UP-DIS) messages
that the CMTS sends to a CM. The CMTS can send an UP-DIS message to a cable modem to suspend
its operation on the cable network. The UP-DIS message can instruct the cable modem to suspend its
operations for a limited period of time or permanently.
After sending the UP-DIS message, the CMTS allows the cable modem back on the network only if the
cable modem is power-cycled, or if the CMTS sends another UP-DIS message re-enabling the cable
modem's upstream transmitter. If a cable modem is already in the suspended state, it must ignore any
further UP-DIS messages except a UP-DIS message re-enabling its operations.
See the DOCSIS 1.1 specification (revision SP-RFIv1.1-I09-020830 and above) for information on the
Note
content and format of the UP-DIS messages.
