Micas Still not working on 3640

[dave_randall]

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:

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

3600 Software (C3640-I-M), Version 12.1(5)T9

Slot 2 NM-6DM MICA-6DM Firmware: CP ver 2730 - 5/23/2001, SP ver 2730 - 5/23/2001.

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.
