I had connected a Router Cisco 2801 (IOS 12.4.11t Sp Services K9) to Sonus GSX 9000 trough a VWIC 1MFT-E1.
Configuration Router:
!
isdn switch-type primary-net5
!
controller E1 0/2/1
framing NO-CRC4
clock source internal
pri-group timeslots 1-4,16
!
interface Serial0/2/1:15
no ip address
encapsulation hdlc
isdn switch-type primary-net5
isdn timer T310 10000
isdn incoming-voice voice
isdn T309-enable
isdn bchan-number-order ascending
no cdp enable
The problem is when I set, for example,
channel 4 as "Out of service" in the Sonus appears "Idle", therefore the calls can use this channel.
Somebody have installed this scenario??

Hi,
primary-net 5 does not really support use of "out-of-service" channels, what are you trying to achieve with that ?

I have a problem, when a channel is blocking, for example if a modem or a call fails, the cisco router set the channel like "Out of services", but the sonus see the channel IDLE, and viceversa.
I can set a channel in the router in "Out of service" with this command in the interface serial:
IPT_ESC4(config)#interface Serial0/2/1:15
IPT_ESC4(config-if)#isdn service b_channel 1 state 2
IPT_ESC4#show isdn service
PRI Channel Statistics:

As you see the channel 1 is "Out of service", but in the sonus I see Idle. I supose when I set "Out of service" in the router, in the sonus, should be the same status?? or not?

Sorry, the debug output is:

Hello,
please send router configuration because it is not normal that the router places channels "out of service". What modem are you talking about? Also collect "debug isdn q931" when the call fail and you see the channel go "out of service".
07-26-2007 02:01 PM
I dont have the output of "debug isdn q931" from the costumer, we have this scenario in a lab, because the fail appears with a costumer. In this lab we put the channel as "Out of service":
IPT_ESC4(config)#interface Serial0/2/1:15
IPT_ESC4(config-if)#isdn service b_channel 1 state 2
I supose that in the sonus the status should be same. When I debug in the lab "debug isdn q931" doesn't send anything.
I debug isdn cc appers this:
*Jul 19 22:11:37.371: ISDN Se0/2/1:15 CCd: CC_SERV_validate_state_change: B-chan 1 OK new locale 0 new service state 2, old locale 0 old service state 0
*Jul 19 22:11:37.371: ISDN Se0/2/1:15 CCd: CC_SERV_ChangeState: lo_chan 1 hi_chan 1 state 2 int_id 0 locale 0
*Jul 19 22:11:37.371: ISDN Se0/2/1:15 CCd: CC_SERV_validate_state_change: B-chan 1 OK new locale 0 new service state 2, old locale 0 old service state 0

Hello,
this is what I was telling you before, isdn net 5 does not support "out-of-service" messages, so you should never use "isdn service" commands.
If the call fails at customer site there must be some reason but you cannot fix that placing the channel out of service.

Ok, which switch type supports isdn service???
07-26-2007 02:15 PM
Some T1 type like dms-100 or NI-2. It is in the documentation.
But believe me, you will not solve anything placing channels out of service. When call fails, there is a reason that you must find.
07-26-2007 02:32 PM
I agree, I was trying in the lab, instead to reproduce the fail, set the channel out of service. But the sonus did not set the channel in out, for the reason that you explain me. Thanks for your answer!

Try explaining what the problem is at customer site is and perhaps someone here can suggest what to do.
