PRI problem on 3745 IOS 12.3(8)T

Hi.I've a strange problem since a few months ago.

I have four NM - HDV2 - 2 T1/E1 on 3745 with IOS 12.3(8)T.Two of these modules have 1 port (E1 PRI ISDN) works fine (all 30 channels are provided) and the other works bad (5 - 6 channel are available at the same time).

I've tested DSPs on both modules and all 15 DSPs are alive.

Someone can help me?

Thanks for all.

check the details using sh voice dsp voice

show voice dsp voice command lists the model of the DSP in use.The DSP NUM lists the number of the DSP. The DSP numbering scheme varies depending on the router platform and the NM in which the DSP is installed. The CH column indicates the DSP channel used for each physical DS0. The number of channels that a DSP can support depends on both the

DSP model and the codec complexity in use

Hi.

I've checked dsp's as you told me and I attach the text file with results.I think dsps are ok.What do you think?

Thanks.

Ciao.

MOreover I changed my Cisco 3745 (with problems) with a new one.The same configuration and the same HDv2 at the same positions (new hardware and new hdv2).Nothing changed!Same problem!!!!

I don't know what to think!!!

Can you upgrade to 12.4(3j) that is the most stable and try again ?

Hi.I didn't find IOS 12.4(3j) so I couldn't try it, but I load IOS 12.3(8)T the same we have on the second voice gateway which works ok (VG2).The VG2 has the same hardware configuration as the first one (VG1) that doesn't work correctly.

I "cut and paste" the two -sh version- :

I don't understand why the same gateway with the same hardware with the same IOS (now) doesn't work in the same way.

It drives me crazy!!!!!!

Can you explain again what is that doesn't work and how do you know that doesn't work ?

I've tested DSPs on both modules and all 15 DSPs are alive.

Someone can help me?
