1760 PVDM DSPs as transcoder

When i use the following IOS commands...most of them arent valid under the 1760 IOS...im assuming commands are different since this is on board DSPs and not in a NM?

For the Transcoder you can follow this procedure, in the step 6 is were you name the transcoder, you need to put that exact name in the transcoder in CCM.

1.- Make sure to put the 'dsp services dspfarm' command on the voice-card that is being used:

AVVID2(config)#voice-card 1

AVVID2(config-voicecard)#dsp services dspfarm

on a show run you should see something like this:

voice-card 1

dsp services dspfarm

---------------------------------------------------------------------------------------------

2.- Configure the interface that is going to talk using skinny protocol with the CCM server:

for example:

AVVID2(config)#sccp local FastEthernet0/0

Enable sccp in the router:

AVVID2(config)#sccp

---------------------------------------------------------------------------------------------

3.- Point the router to talk sccp with the CCM server

sccp ccm <ip address of the server were the phones are registered> identifier <any number> version <version of the CCM server>

for example:

AVVID2(config)#sccp ccm 192.168.4.10 identifier 27 version 3.3

---------------------------------------------------------------------------------------------

4.- Create a sccp group:

You will associate this group to the identifier from step 3 and will assign a priority to the group.

AVVID2(config)#sccp ccm group 27

AVVID2(config-sccp-ccm)#associate ccm 27 priority 1

---------------------------------------------------------------------------------------------

5.- Create a dspfarm profile:

In here you will specify if its going to be a conference, transcoder or mtp:

AVVID2(config)#dspfarm profile 27 transcoder

Then you will associate the profile to the sckynny application:

AVVID2(config-dspfarm-profile)#associate application sccp

Enable the dspfarm profile

AVVID2(config-dspfarm-profile)#no shutdown

---------------------------------------------------------------------------------------------

6.- Associate the ccm group to the dspfarm profile

AVVID2(config-sccp-ccm)#associate profile 27 register CCMTRANS

Note: CCMTRANS is a name that you gave to the Transcoder and MUST be the same as in the CCM server

---------------------------------------------------------------------------------------------

Re: 1760 PVDM DSPs as transcoder

please see the following link for features and configuration of transcoding on the 1760:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vvfax_c/callc_c/ccm_c/intcnf2.htm#wp1052594

also, if you cannot issue the commands as described then you may have to upgrade to an IOS that supports them as you require.

you can use the feature navigator link below to find the correct IOS for your platform that supports what features you like:
