I am experiencing a very curious issue. I can't seem to find the problem in the CMTS configuration. Let me explain: I have a specific model of HITRON cable modem that doesn't connect to MAC 3 but works fine with the other MACs. The modem fails to lock onto the downstream carriers and keeps rebooting. I am sharing the configuration of MAC 3 (which has issues with this modem) and another MAC where the modem works.
We have UBR10K systems and want to force narrowband modems offline or severely restrict their bandwidth. We want the resident/customer calling in to get the issue fixed and not taking away from the bandwidth of the 8x and 16x groups. Does anyone have any suggestions of how best to accomplish this? Thanks.
Is this signal level optimal for cable modem to operate correctly? (EuroDocsis 3.0)

Arris TM902 modem can't lock to DS frequency: it constantly scan all DS frequencies, although prints "Got energy" on the correct frequencies (330, 338, 346 MHz..) but continues scanning cycles, include Annex B frequencies. I tried to set 'startup_ds_frequency 338', but this doesn't help. Also, what cause these error messages in Event log:
SYNC Timing Synchronization failure - Failed to acquire FEC framing;
SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;
Hi everyone! I have a Casa C40g, and I would like to know if it is possible to create a rule during load balancing that identifies a specific modem based on its MAC vendor and assigns it a static group of 16 carriers ???? .
