[cisco-voip] ISDN T1 voice calls hardware validation

Hi again

We are preparing the hardware request

I am not sure, should we get NIM-8MFT-T1/E1 modules or NIM-8CE1T1-PRI modules ?

the clear-channel vs channellized channel is not clear for me

thanks

Pat

  Pat -
  Also let’s look at the hypothetical ASR you’re wanting versus the ISR. 



  The ASR1006 supports 12 half height SPAs in 6RU of space.


  To keep this simple and not get into codec complexity, let’s assume that the DSP SPA is matched 1:1 with the 8xT1 SPA. 


  That gives us 6 8xT1 SPAs providing a total of 48 T1 ports and 1,104 PRI channels in the 6RU. 


  The ISR4451 supports 5 8xT1 NIMs providing a total of 40 T1 ports and 920 channels in 2RU. 


  Three ISR4451 boxes would give us a total of 120 T1 ports versus the 48 in a single ASR1006 for the same rack density.


  Hopefully you see the reason why the ASR just isn’t the right platform for voice T1 termination.  Now SBC is a totally different story and you can chock it full of DSP SPAs and make a huge transcoder which the ISR can’t do because it doesn’t have enough DSPs.

    ok

    I guess we will have to look for another product like the ISR4k

    the ASR1006 was very interresting because it was full redundant
    and we could put several 8xT1 card in it to have greater density

    the ISR4k seems to be limited to 3 cards and is not redundant.

      I replied privately but the SPA-DSP was built for SBC transcoding using CUBE between SIP or H323 trunks.  Unless something has changed recently it cannot be linked to the T1 SPA to terminate PRI Voice. 


      To terminate voice from a PRI you will need to use one of the ISR products and the relevant T1 module with DSPs. If you’re using the latest it would be an ISR4k with the NIM first mentioned and make sure the DSPs are onboard the NIM.

        Not sure if DSP is onboard the SPA like the NIM; I’d have to look that one up ... you might try dsp services dspfarm under the voice-card configuration parameter. I’d also disable cdp on the serial interface.

            I assume you have the card type specified and controller interface configured with timeslots? 


            Can you send the running-config and code version?

              Hi

              I get this error

               **ERROR**: call_incoming: Received a call id 0x2F with a bad bearercap from xxxxxxxxxx on b channel 1

              seems like the dsp are not associated with the t1 card

              in the config we don't have acces to the following :
              isdn incoming-voice voice
              which should go on the Serial interface. 

              we also don't have the "port" command that should go in the dial-peer voice section

              any ideas ?

              Thanks

                That correct! I misread! Yeah the shared port adapter T1 should work.

                  Thanks for your help

                  But there are no NIM slot in the ASR1006 chassis

                  NIM is for ASR1001-X I think

                    For isdn voice you’ll need a NIM-8MFT-T1/E1

                      Can someone help us validate if we can use this hardware to receive voice calls from a isdn T1 (23B+D) and send them in SIP to a softswitch and vice-versa

                      ASR1006
                      SPA-8XCHT1/E1
                      SPA-DSP
                      ASR1000-RP2
                      ASR1000-ESP40

                      in short can it be used to build a voip gateway like an audiocode mediant or a patton smartnode

                      Thanks
