Hi!
I'd like to have a universal way to disable the SIP eMTA in modems when customers don't use it. We have Scientific Atlanta EPC2203, EPC3212, Motorola SBV6120E, Compal CV6181E, Arris TM501B, TM502B and possibly one or two other types with built-in IP telephony. I have tried setting ifAdminStatus.16 Integer 2; (eMTA IF number is 16, status 2 is shutdown) but then the modems (at least SB5101NE which has no eMTA) keep rebooting and complain about " TLV-11 - Illegal Set operation failed". I need this to work with both eMTA modems and data-only modems like the SB5101E. This is because I'd like to have one file for modems with active SIP and one for modems with no SIP (which includes modems without SIP support AND SIP modems with no telephony subscription active) to simplify provisioning.
I have tried to read the SNMP MIB PKTC-IETF-MTA-MIB::pktcMtaDevEnabled from the modems but it doesn't seem to exist on any of the models I have.
Any thoughts? Vendor specific TLVs perhaps (need to put in all vendor's TLVs then...)?

Put option in Your DHCPD.conf like this:
host mta.cm-201.104 {option option-122 01:04:00:00:00:00; hardware ethernet A4:A2:4A:3D:D0:47; fixed-address 10.10xxxx
That prevents loading MTA part - works for all modems.
Edit:
I forgot - include also option option-122 code 122 = string; this declaration in global mode.
Hi!
Thank you for your reply, but I'd like a way to do this with the CM config file if possible. If I can do it in the file, I won't need to change things in several places, but only assign the correct file to the modem. I'll give it some extra thought if the way you suggested is suitable for me, but until then, perhaps someone else has a way of doing it with for instance TLVs in the CM config?
