How to connect Mitel sx2000 pbx to a cisco router using vwic2-2mft-t1/e1

Hello All,

I would like to connect a 2911 cisco router to sx2000 pbx using vwic2-2mft-t1/e1 card. The signaling protocol is used in sx2000 is DPNSS.

The cisco router has E1 card, and the card is configured like this:

!

isdn switch-type primary-dpnss

!

controller E1 0/3/0

framing NO-CRC4

clock source internal

pri-group timeslots 1-4,16

!

!

interface Serial0/3/0:15

no ip address

encapsulation hdlc

shutdown

isdn switch-type primary-dpnss

isdn incoming-voice voice

isdn dpnss pbxA

no cdp enable

!

when I do this command

#sh controllers E1

E1 0/3/0 is up.

  Applique type is Channelized E1 - balanced

  No alarms detected.

  alarm-trigger is not set

  Version info Firmware: 20100222, FPGA: 13, spm_count = 0

  Framing is NO-CRC4, Line Code is HDB3, Clock Source is Internal.

  Data in current interval (245 seconds elapsed):

     0 Line Code Violations, 0 Path Code Violations

     4 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

     4 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

  Total Data (last 24 hours)

     0 Line Code Violations, 0 Path Code Violations,

     1652 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,

     1652 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

But I still I can not make any calls between the pbx and cisco router.

I confirmed that no-crc4 is used in the pbx and when changed I go the E1 status down.

Any suggestion or help would be appriciated?

Thanks
