modem can't lock to DS frequency

Forums: 

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;;

CASA C40g MAC VENDOR and Load Balance

Forums: 

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 ???? .

Thanks.

RFC 868 Time (The Death of xinetd in RHEL)

Forums: 

This may be relevant to few if any, but in testing an upcoming upgrade to the time server for our RPDs/iNodes we realized that RHEL 9 (and subsequently our current choice, AlmaLinux) dropped xinetd from the available packages. This may be with good reason, as apparently the project hasn't updated in over a decade.

Because I have an ironic sense of laziness, rather than add another OS to my administrative workload, I opted to write a little daemon in Rust that responds to RFC 868 Time requests via TCP, UDP or both.

Hello dears!

I have one tricky question:

I would like to run a PNM test over a whole upstream Interface but i'm not quite sure how to approach to this?
at the moment i'm doing this :

Low US TX and Low US RX

Forums: 

Have one modem that doesn't transmit on correct US TX level.

The modem is only transmitting at 34.5 and the RX on cmts is -9.
The modem is supposed to adjust its transfer levels up until US RX is 0, but it doesnt.
What can be the cause of this? Faulty modem?

Disable EMTA from mta config file.

Forums: 

I'm testing disabling the MTA portion of EMTA modem devices, to keep the MTA portion from hammering my DHCP server. I've setup a pool for these and assign them an IP, which calms it down, but I'm wondering if I can disable the MTA portion from my mta config file.

what is the oid or mib that can be used to locate a CM OFDMA upstream interface , cable labs or Arris MIB?

Forums: 

Hello dears,

Currently I'm on search of some wisdom.

I need to know via snmp to which ofdma interface a certain cable modem is connected to by providing the
mac address alone ( if that makes sense):

for example mac address A:B:C:D

1.3.6.1.2.1.10.127.1.3.3.1.5.(cm_index) = sc if_index

I thought this will do but it returns the SC upstream index only, I need the same but for ofdma.

thanks a lot in advance if any colleague has some idea to achieve this.
