Docsis chat

I'm having some issues with SNR stability in low freq.

Here's the deal:

We have 4 Upstream channels for each optical node.
Our 4 channels are in 36.8Mhz, 30.4MHz 24MHz and 17.6MHz.
We have 54 nodes that are using the 17.6MHz freq. In around 70% of those 54 nodes, we experience high noise in the 17.6MHz freq. Which results in SNR lower than 25dB.
We are having issues finding out what causes this, so we spent. around 3 or 4 days sweeping the entire node, looking for the source of noise (which usually is a faulty installation inside customers premises)

Hello all,

A little background first before I pose the question/issue. We are currently running a number of different model cable modems using a "catch-all" cm file. The modem models currently deployed on our network are Arris models: DG860, DG2470A, DG3260A, DG3270A, TM3402A, and TG3452A. The modems are set as provisioned mode docsis only as the built in telephony adapter is not utilized on our network yet. We are using a stand alone Cisco/Linksys SPA122 or SPA-2102 which connect to our sip/metaswitch environment.

Hi,

kind of silly questions, but I want to understand what is being used around your plants:

1) What is the parameter you use to consider a service group (downstream or upstream) saturated?

2) Do you measure it by peaks or average?

3) Are your node splits related to this metric?

If you answer to question 3 is "yes", how long it takes from the moment the trigger is fired to the actual physical node split?

the Cisco EPC3008, SNMP show only part of MIBs, mainly standard IETF MIBs, but private enterprises MIB entities are hidden.
Private MIBs are accessible for console commands, though. How to unhide these MIBs, to access them via standard SNMP, over UDP port?

good morning everyone
currently have the following modems with super old firmware. some drop from 3.0 to 2.0 when I go from 24 channel to 32 channel bonding.
Does someone have newer firmware and cert files so I can do an upgrade
Pace model D5001 current firmware 1.407.2.25 (would need cert file)
Arris modem cm820A current firmware 7.5.55 (already have the cert file)
Arris modem dg860p2 current firmware 7.5.50a (already have the cert file)

best to send via wetransfer dot com my email is cmcaldas at gmail dot com

Good day to all, I was wondering if someone may have a firmware file for eMTA: TG1682G that can share it. It can be MGCP or SIP, I have some samples in my lab but I have seen many differences as they have different versions, and would like to change them using a firmware file. Thanks in advance. Regards.-

Hello,

I'm trying to programatically generate an Cisco EPC3212 template for each customer with its sip options but when I'm trying to use all saEmtaSipDevice* mib objects i'm getting


# docsis -e cisco.cfg my_key_file cisco.bin
/* Error: Can't find oid saEmtaSipDeviceDigitMap.0 at line 5 */
encode_vbind: Unknown Object Identifier (Sub-id not found: (top) -> 1)
got len 0 value while scanning for SnmpMibObject
at line 5


Reading in other forums i found that I need SA-EMTA-SIP-MIB.mib mib file but I can't find it.

Hey
i have a problem tftp server / modem or ....

i have linux router
i installed dhcp server + tftp server for modem
modem dont get filename ( config file name )
in log i see only:

how to enable telnet on cisco EPC3008 (DPC3008)? Already have enabled remote_acc_methods (telnet | ssh), telnet_ipstacks (IP1 | IP2), telnet username & password, telnetIpStackInterfaces.0 hex_string 'C0', telnetServerControl.0 int 1
but telnet port on CPE is not opened, always get "Unable to connect to remote host: Connection refused".

All,

Just a regular technical guy (engineer), with no experience in the industry looking for a sanity check.

This is my question->Is there any explanation for why i cant to a simple repetitive ping test to a Ariss 804G modem that isn't connected to the coax without getting significant failures ? Getting intermittent periods of like 60 seconds where the ping returns general failure. Occurs every 20-40 minutes.

More details are below.
