Fire Panel Dialer to Grandstream HT818 ATA

I found myself in quite a pickle recently as a client needed a fire alarm dialer hooked up post haste for an inspection. I figured, “no problems, ire mon, bobsled.” Two and a half hours later it was working…perhaps it was more difficult than I thought. Here’s my config to get it working.

All of these configurations are done under the profile menu.

First is the DTMF method:

Priority 1 needs to be set to in-audio. This will take the DTMF tones and just shove them into the audio stream.
Disable DTMF Negotiate should be set to Yes so that it will grab in-audio and go with it.

Next is setting the codec to be used; Grandstream calls it vocoder:

Set “use first matching” to yes so it will use the supplied list.
Then set them all to PCMU which uses G.711U. Since this is the least compressed codec it is best for DTMF dialers.
I also set voice frames per tx to 10. It should be in a range of 2 – 10, and 10 seemed to work well.

Last is disabling echo cancellation:

First the dialer is a good distance from my ATA so I set the gain to -6 and Rx to -4.
Now disable both the Line echo canceller and the network echo suppressor.

After making these modifications and sacrificing two chickens everything started working. Good luck errbody!

Simple Interface Policing In IOS-XR (ASR9000)

First I’ll create a simple policy that will match on 2gbps. The policy map in IOS-XR is a dream, it lets you specify speed in bps, kbps, mbps, or gbps…stupid simple.

policy-map 2gig
 class class-default
  police rate 2 gbps
   conform-action transmit
   exceed-action drop

So class “class-default” is a built in class that basically says “match all”.
Conform action is transmit, so as long as they are within 2Gbps all it through.
Exceed action says everything else, drop.

Now apply the limit to my interface:

interface TenGigE0/1/0/11
 description [Customer 1]
 service-policy input 2gig
 service-policy output 2gig

Good luck and happy rate-limiting.
