MTA Mibs / Telephony

Anybody have the MIBS for Arris modems:

TM822, TG862, TM804?

Seems I'm missing the critical pieces to getting MTA's to work here. Never been done here, so flying entirely blind.

I am using Incognito DHCP Server.

there is at least 2 different

there is at least 2 different ways to do MTAs
SIP and MGCP (NCS)
they use different firmwares and oids from the same mibs

you need a support contract from Arris to get the firmware and manual.

there are several posts on this forum on setting it up but here is the gist

DHCP --
You set option 122 on your dhcp server

in dhcpd you have to create the option space
# Map option 122 values for booting packetcable Devices
option space docsis-mta;
option docsis-mta.dhcp-server-1 code 1 = ip-address;
option docsis-mta.dhcp-server-2 code 2 = ip-address;
option docsis-mta.provision-server code 3 = { integer 8, string };
option docsis-mta.as-req-as-rep-1 code 4 = { integer 32, integer 32, integer 32 };
option docsis-mta.as-req-as-rep-2 code 5 = { integer 32, integer 32, integer 32 };
option docsis-mta.krb-realm-name code 6 = string;
option docsis-mta.tgs-util code 7 = integer 8;
option docsis-mta.timer code 8 = integer 8;
option docsis-mta.ticket-ctrl-mask code 9 = integer 16;
option docsis-mta-pkt code 122 = encapsulate docsis-mta;

then configure it this goes in the modems dhcp section
option docsis-mta.dhcp-server-1 192.168.0.1;

then for your MTAs in dhcp you have to point them to a bootfile, which looks a little different depending if you MGCP or SIP

here are the decoded version (using docsis opensource tool) of each one.
