    atlas 830 E1 connection to AudioCodes Mediant 3000

      Hello,

      We have adtran 830 (rev A04) with E1 modules. We are trying to connect to an AudioCodes M3K. The AudioCodes is set to: generate clock, crc4, HDB3, Network side EuroISDN.

      We are getting a D-channel alarm on the AudioCodes side:

       

      On the AdTran side:

      When we change the the "auto alarm" setting the AudioCodes sees the change and reflects the AIS or RAI so the cabling looks to be correct.

       

      Any suggestions would be greatly appericated...

          Thank you for using the ADTRAN Community Support Forums.

           

          I'm not positive which port, in the screen captures above, you are using. If you are using PORT 2, then it is showing an LOS (Loss of Signal) alarm, which means it is not receiving any signal on that port. This would indicate a cable issue.

           

          If you are using PORT 1, then do you have it configured as a NETWORK TERM or USER TERM entry in the DIAL PLAN? The ATLAS it is configured based on what it is terminating, so when connecting to a NETWORK PRI (or a PRI from equipment acting in a Network role) the ATLAS PRA should be configured as a NETWORK TERM entry (the ATLAS is in a "user role"). When connecting to user equipment, or equipment in a user role, the ATLAS PRA should be configured as a USER TERM entry (the ATLAS is acting in the "network role").

           

          Hope this helps,

          Patrick
