We have a 2951 router running IOS c2951-universalk9-mz.SPA.151-1.T.bin that has the following pvdm modules installed :
NAME: "PVDM3 DSP DIMM with 64 Channels on Slot 0 SubSlot 4", DESCR: "PVDM3 DSP DIMM with 64 Channels"
PID: PVDM3-64 , VID: V01 , SN: FOC14191CG0
NAME: "PVDM3 DSP DIMM with 64 Channels on Slot 0 SubSlot 5", DESCR: "PVDM3 DSP DIMM with 64 Channels"
PID: PVDM3-64 , VID: V01 , SN: FOC14200GHB
NAME: "PVDM3 DSP DIMM with 32 Channels on Slot 0 SubSlot 6", DESCR: "PVDM3 DSP DIMM with 32 Channels"
PID: PVDM3-32 , VID: V01 , SN: FOC141121L1
There are a total of 3 E1 interfaces installed and up and running.
When I codfigure a transcoding resource like this :
dsp services dspfarm
sccp local GigabitEthernet0/0
sccp ccm X.X.X.X identifier 1 priority 1 version 7.0
sccp ccm X.X.X.X identifier 2 priority 2 version 7.0
sccp ccm group 1
bind interface GigabitEthernet0/0
associate ccm 1 priority 1
associate ccm 2 priority 2
associate profile 1 register XXXXXXXXXX
dspfarm profile 1 conference
maximum sessions 10
associate application SCCP
All is working fine and the conference is registered. When I reload the router, the PVDM in slot 2 (so the PVDM3-32) is showing an amber light.
when I shutdown the dspfarm profile 1 conference, the light turns green and stays green when I do a no shut.
A second strange behaviour we have is the following. We have configured a trunk-group on 2 of our e1 controllers. whenever we reload the router, this configuration disappears (yes the config is saved before doing the reload).
Thanks in advance for your help.
