PVDMs, DSP farms, et al.... next steps?

Hi all,

I'm in the process of migrating from 6608s to 3945s. I've got all the pieces and I'm just wondering about next steps.

I've found the following documents:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/media.pdf

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cminterop/configuration/15-1mt/vc-enh-confr-vgr.pdf

But I'm wondering if there are any others people can recommend.

Also, if there are any hints or recommendations on going forward, that too would help.

I'll have two 3945s, each with a PVDM-256 installed that I need to use for 8 T1s into each router, and for conferencing mainly. But I'll also want to try and do some transcoding if possible.

Thanks, Lelio

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Are you asking about DSP allocation for each application or how to configure?

Have you tried the DSP calculator?

Use pvdm3-xxx because you get the video codecs but the drawback is faxing does not work well ... I have a client that uses t37 on ramp and that stopped working... they are around on the tac case trying to get that back.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

definitely using PVDM3s on the 3900s.

for the others re: DSP calc tool - yes, did use that to do the initial calculations. i've got the PVDM3 256 already installed.

i'm looking for more information about complexity, sharing, etc.

i'll first look through the docs i posted and then post specific questions...

You definitely need to make sure that cisco fax-relay is not used on your network as it is no longer supported with the PVDM3’s.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

well, i read the first two docs i mentioned, and, i'm not too further along. looks like there's one more i should look at:

http://www.cisco.com/en/US/customer/docs/routers/access/1900/software/configuration/guide/pvdm3_config_ps10538_TSD_Products_Configuration_Guide_Chapter.html

Subject: PVDMs, DSP farms, et al.... next steps?

Hi all,

I'm in the process of migrating from 6608s to 3945s. I've got all the pieces and I'm just wondering about next steps.

I've found the following documents:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/media.pdf

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cminterop/configuration/15-1mt/vc-enh-confr-vgr.pdf

But I'm wondering if there are any others people can recommend.

Also, if there are any hints or recommendations on going forward, that too would help.

I'll have two 3945s, each with a PVDM-256 installed that I need to use for 8 T1s into each router, and for conferencing mainly. But I'll also want to try and do some transcoding if possible.

Thanks, Lelio

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

ok, that last document didn't help much either.

so here's a couple of general questions:

where/when do i need dsp farm'ing? can i go without it? do i need it for conferencing/xcoding/MTP?

when enabling dsp farm'ing, i can see a couple of examples which state "voice-card 0" what is this voice-card 0? is this the motherboard? is this the DSP chip itself? if i install another DSP chip, would I see "voice-card 1"

thanks everyone!

If you insert a NM-HDV2 in slot 1, that would be configured as "voice-card

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Thanks for this. A couple of more questions:

I read that you have to have enough DSP resources for all your voice ports (T1s in particular) and you can't overprovision. Just wondering the validity of this statement (from NetPro post) and whether this is for cards that are inserted, or turned up.

Also, with respect to codecs, can you configure different codecs on the same DSP? It talks about FLEX for the PVDMs, and I'm just wondering if that's the best approach.

Thanks again for everyone's help.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

In my experience I have never been able to 'oversubscribe' DSP resources so
that is true. I believe, and someone please correct me if I am off on
this, DSPs are 'reserved' when the T1/PRI interface is turned up. So, if
you had an interface configured as a 'hot' standby in case your primary PRI
port goes bad, it would use DSP resources.

Think of the consequences of being able to do overprovision. If you have
conferencing, MTP, transcoding and 8 PRIs configured and all of your DSPs
are in use for conference and MTP, you are going to be in trouble when
people start complaining they can't make or receive calls to/from the PSTN.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Any idea if there is a command that you can use to show what DSP resources have been reserved for this?

when enabling dsp farm'ing, i can see a couple of examples which state "voice-card 0" what is this voice-card 0? is this the motherboard? is this the DSP chip itself?
PVDM2/3 modules installed in the slot on the motherboard.

if i install another DSP chip, would I see "voice-card 1"
If you insert a NM-HDV2 in slot 1, that would be configured as "voice-card 1". Answer is no.

Subject: PVDMs, DSP farms, et al.... next steps?

Hi all,

I'm in the process of migrating from 6608s to 3945s. I've got all the pieces and I'm just wondering about next steps.

I've found the following documents:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/media.pdf

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cminterop/configuration/15-1mt/vc-enh-confr-vgr.pdf

But I'm wondering if there are any others people can recommend.

Also, if there are any hints or recommendations on going forward, that too would help.

I'll have two 3945s, each with a PVDM-256 installed that I need to use for 8 T1s into each router, and for conferencing mainly. But I'll also want to try and do some transcoding if possible.

Thanks, Lelio

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

I noticed something about 'reserved' credits, etc with the output of a 'show dsp-group all'. I wonder if these numbers change as T1 ports are turned up.

router#show dsp-group all
DSP groups on slot 0:
dsp 1:

Max signal/voice channel: 43/43
Max credits: 645, Voice credits: 645, Video credits: 0

Transcoding channels allocated: 0
Group: FLEX_GROUP_VOICE, complexity: FLEX
Shared credits: 645, reserved credits: 0
Signaling channels allocated: 0
Voice channels allocated: 0
Credits used (rounded-up): 0
Slot: 0

In my experience I have never been able to 'oversubscribe' DSP resources so that is true. I believe, and someone please correct me if I am off on this, DSPs are 'reserved' when the T1/PRI interface is turned up. So, if you had an interface configured as a 'hot' standby in case your primary PRI port goes bad, it would use DSP resources.

Think of the consequences of being able to do overprovision. If you have conferencing, MTP, transcoding and 8 PRIs configured and all of your DSPs are in use for conference and MTP, you are going to be in trouble when people start complaining they can't make or receive calls to/from the PSTN.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Once you build the channels on the controller "pri-group timeslots 1-24"
the DSP resources are locked, FXS and FXO lock on bootup.

I think that command you're looking at will show you what you want, you can
see the transcoding towards the bottom

Once you build the channels on the controller "pri-group timeslots 1-24" the DSP resources are locked, FXS and FXO lock on bootup.

I think that command you're looking at will show you what you want, you can see the transcoding towards the bottom

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

You can still overprovision.

Examples:
-In the PVDM3's conferences are not reserved upon configuration.
-You are locking up G.711 (low complexity) codec, not a high complexity
codec
-Transcoding sessions are not locked upon configuration
-Video transcoding/switching sessions are not locked

So if you're using non G711 codecs, transcoding, conferencing, MTPs, or
video, you can overprovision. If all you're doing is G711 termination to
POTS/PRI I don't think you can.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Nick,

Could you clarify your point of being able to over provision here? From my
experience, as you add sessions to one service, it dynamically reduces the
available sessions on the other services.

I.e., If you do a ? on sessions for transcoding, it might say <1-40>. But
if you go and add a few more conferencing sessions first, and come back, it
will be lower. Say <1-32>. I'm making these numbers up, but the fact
remains, the maximum number you can type in, is limited by the available
resources at config time.

Thanks for sharing. I look forward to your response.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Take the simplest example - PVDM3-16 on a partial PRI.

The 16 channels will be allocated to the PRIs, but as soon as one of those
calls is G.729 you won't be able to get 16 calls through.

I haven't played with the allocation on the PVDM3's as much as in the back
end it's a lot more complex than the 2's.

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

Basic stuff, but I haven't found the definitive answer yet. If I have one PRI but using only 10 channels (and H323), with one PVDM3-16 is enough? Is it the same for MGCP?

Thanks!

Take the simplest example - PVDM3-16 on a partial PRI.

The 16 channels will be allocated to the PRIs, but as soon as one of those calls is G.729 you won't be able to get 16 calls through.

I haven't played with the allocation on the PVDM3's as much as in the back end it's a lot more complex than the 2's.

Nick,

Could you clarify your point of being able to over provision here? From my experience, as you add sessions to one service, it dynamically reduces the available sessions on the other services.

I.e., If you do a ? on sessions for transcoding, it might say <1-40>. But if you go and add a few more conferencing sessions first, and come back, it will be lower. Say <1-32>. I'm making these numbers up, but the fact remains, the maximum number you can type in, is limited by the available resources at config time.

Thanks for sharing. I look forward to your response.

You can still overprovision.

Examples:
-In the PVDM3's conferences are not reserved upon configuration.
-You are locking up G.711 (low complexity) codec, not a high complexity codec
-Transcoding sessions are not locked upon configuration
-Video transcoding/switching sessions are not locked

So if you're using non G711 codecs, transcoding, conferencing, MTPs, or video, you can overprovision. If all you're doing is G711 termination to POTS/PRI I don't think you can.

Once you build the channels on the controller "pri-group timeslots 1-24" the DSP resources are locked, FXS and FXO lock on bootup.

I think that command you're looking at will show you what you want, you can see the transcoding towards the bottom

Re: PVDMs, DSP farms, et al.... next steps? [In reply to]

If you configure a fractional PRI with "pri-group timeslots" on the T1 controller and are using G.711 then you will only need 10 channels so the PVDM3-16 will work. It definitely works with H.323. As I recall you can do it with MGCP also, but Callmanager won't know it's fractional so you might run into problems.
