  Pat -
  I will agree that the ASR1k offers redundant RPs but by the time you 
configure it the way you want, you'd probably find dual ISR4k's to be the same 
cost.  Just a guess there as I haven't ran the numbers but I know the ASR comes 
at quite the premium over the ISR.



  The ISR4k offers an 8xT1 NIM and the ISR-4451 supports 5 NIMs (using SM-X NIM 
adapter) which gives you 40 T1 ports and 1200 E1 channels or 920 T1 channels in 
a single 2RU box.


  For the ASR to do voice decoding it would have to carry the TDM clock signal 
from the T1 SPA to the DSP SPA which doesn't happen.  On the old ISRG2's and 
older we carried the TDM clock across the backplane which meant you had a 
single clock domain inside the entire box.  The problem with that was you could 
encounter line slips if one of your circuits was not coming from the CO or from 
even the same provider in the same CO.  As a result, the new ISR4k does not 
carry the TDM clock outside of the NIM module and so the DSP resources all 
reside locally to the T1 cards themselves.  This means that you have to keep 
the same providers/CO on the same NIM but you can bring other providers/COs 
into other NIMs and have separate clocking domains.  This is huge for teleco 
redundancy across your PRIs.

    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.

                  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

                      Pat
