    Getting DNIS error in "Rabbit-Hole" configuration

    ben-matson New Member

      I've got our ATLAS 500 all configured with the "Rabbit-Hole" configuration and are able to make and receive calls, but when I connect the unit to our alarm receiver and do a test call it reports it isn't getting a valid DNIS.  When I connect a test set and call the unit when I pick up the line I get a single string of DTMF, but according to my receiver guide I need a 500msec pause, send DNIS, a 2000msec pause, then send ANI, so I should be able to hear a pause between the the DNIS and ANI DTMF, but all I hear is one long string of DTMF.  Is there any settings I'm missing to set this timing?

       

      Thank you,

          The ATLAS rabbit-hole configuration does not have any "pause" by default. The DTMF digit has a duration of roughly 75 ms, with an interdigit delay of roughly 75 ms as well. The DTMF digits are in the format of *ANI*DNIS* with the asterisk (*) being transmitted at the beginning of the digit string, in between the ANI and DNIS, and then to signify the end of the digit string. The ANI is transmitted first, followed by the DNIS.

           

          It may be possible to add a pause under the DIAL PLAN in the SUBSTITUTION TEMPLATE to some extent. A comma (,) can be used to introduce a 1/2 second delay, but the comma is also considered a "digit" so you will have to adjust the DID DIGITS TRANSFERRED to include the comma(s). The asterisks (*) will be transmitted and cannot be removed in the substitution template, as they are the delimiters to indicate the start of the digit string, the separation between ANI and DNIS, and the end of the digit string. This is the ATLAS' implementation of Feature Group D using DTMF tones (as opposed to MF tones - and the ATLAS 550 does not support MF tones).

          So to add a 500 ms delay before the DNIS, you can set up the SUBSTITUTION TEMPLATE with a DNIS ORIG # of "XXXX" and a DNIS SUBST # of ",XXXX".

           

          Hope this helps to clear a few things up,
