I posted further down about problems with our NM-6DM MICA modems on our 3640 not training with any client modems we have tried. Following advice received I upgraded the portware firmware to 2.7.3.0. This does not seem to have made any difference. I have telnetted into the devices and they are all reporting the following for an AT\S command:
Cisco MICA Hex Modem Link Statistics

I assume that the ! Invalid DSP status ! is not what you would expect. Any ideas what may be wrong?

Thanks in advance

This type of issues often needs advice from the Cisco's TAC engineers..You can open a case at http://www.cisco.com/tac.
Pl. enable the following debug on 3600
debug modem
debug modem csm
Present with the sh run and sh ver from the router.
Now make sure that you run following modemcap for the modems for 2.7.3.0 as portware.
&F&D2S34=18000S40=10S54=456debugthismodemS71=4
All-n-all opena a case on this issue...Thanks..Tejal

I would not be too much worried about "Invalid DSP status" as I see this for systems running fine.
Modem and modem csm debugs will reveal if there still is problem in connecting with pw 2730
along with the recommended modemcap.
