The title says it all: Arris C3 TM502G Stuck in MTA DHCP DISCOVER/DHCP OFFER loop. The cable modem part and the CPE behind the modem work just fine, but the MTA will not accept the offer from the DHCP server. We've followed the posts on this site to the letter and I've set up many many sites with Arris CMTS 1500s so I'm pretty sure the problem is in the C3 config. In the advanced features of the EMTA under " MTA DHCP PARAMETERS " I see that the "MTA FQDN" is incorrect. It's getting the FQDN of the cable modem. Any ideas?
I Am trying to configure a ubr7111.. i want to set 2 dhcp pools 10.100.0.0/24 for the modem pool which is primary and 10.1.0.0/21 for the cpe pool which is secondary. Modems are getting online just fine .. but the only problem is that cpe is getting ip's from the modem pool. Here is my current running-config PLS HELP.

So what is the good, bad, and ugly about the DCM-2000's from anyone with experience with these things?
I have a line on a couple that may suit a particular application that I'd prefer to keep off of my uBR if possible.
(Off-campus college housing network our system serves).
I know they're only 1.1 boxes, but have read they have a fairly high upstream bandwidth ceiling along with decent CPU efficeincy and are good performers for a 1X8 CMTS.
I need help regarding SIP on SBV5121E. Particularly I'm interested in:
1) Does it requires special firmware, what version and could somebody provide me with this firmware?
2) Is it possible to run SIP over TCP instead UDP with this modem?
3) Could somebody provide me MTA config file for such implementation?
I have a question related to the VoIP server (sip,mgcp). Which voip server, which sw and hw to use 3play services, provision of related services telephony.
Does anyone use an asterisk voip server and the user terminates.
Thanks
We are having issue with MTA that when a VoIP call established, there was no upstream voice at the very beginning of the call. We are using Arris 502 and 602 EMTA, and Terayon BW3200 CMTS. The upstream modulation is 16QAM. We have tried to enable DSX QoS in modem config file, but there were about 100 out of 320 MTA could not get online with the config file with DSX QoS enabled. MTA went offline immediately after received the modem config file. Those MTA were across all upstreams. Each time, the modem received the log as follows,
Hi
I have a C3 CMTS and MTA from Arris and SA.
My files don't have service flows, because the C3 create the service flows itself.
When use the Arris 501 I don't have delay, but a lot of delay wit SA DPC 2203, anyone has SIP working with C3 and DPC 2203 ?
Any idea to trace the delay cause ?
Best Regards.

Any idea about this problem ? any clue how to start to figure out whats happening ?
