PRI-Channels Idle *

[cowherjohn]

I have built a new equipment tie line, with a PRI, IFC type is 5ess, the span and dchannel come up with no errors and calls go into the Option 11 just fine, but cannot dial out. When the trunks/channels come up they are displaying "Idle *"

Can someone input why they come up with the * , I can also see the PBX try to make calls go out by viewing the dchannel, by viewing the MSGI/MSGO. It appears as though calls are going out but there is no audio, the other end actually rings, when the caller picks up it is dead air???

 

[johnpoole]

the * is because it's a pri. post the config and the d, and maybe we can help

for testing turnof nd2 onthe rcap and trmb to no. in ld 96 star serv, that may needs to toggle.. it could be you've missed dis msdl 1 all, enl msdl 1 fdl to load your software onto the msdl card.. that takes down ALL channels on a msdl, map dch will show the usage on that card

Make sure that CLID table 0 is programed. Some carriers need to see all 10 digits.

 

[cowherjohn]

Thanks for your response,

johnpoole: I have turned off nd2 on the rcap, and trmb to no,

I am not certain what you mean " in ld 96 star serv, " ?

This system has the DCHI card with the dchannel daughterboard not a MSDL card, does your map dch still pertain.

I am seeing that the Nortel Puts the Dchannel on channel 31 when you do a stat in LD 60, and not on channel 15 like normal E1, is there a way to change that?

 

[superiortel]

Usually with 5ess you need to enable service messages on the D-channel to help recovery of the D channel after an interruption (eventhought I don't think this is the problem)
Disable the d channel (ld 96 dis dch 14)
Disable the loop (ld 60 disl 1)
Disable MSDL 1
Enable services on d-channel (ld 96 stat serv (to see) ld 96 enl serv 14)
enl MSDL 1 fdl

I noticed on your D channel the label "Cisco", is this a VoIP interface ? If so, chances are that your problem is IP routing not enabled on the Cisco, that causes one-way audio problems and likewise, (you reported ring and dead air)

Also, the D on channel 31 has to be right, otherwise you would not ring thru. (And again, never done E1 myself)

 

[johnpoole]

yes the map does still work, the above post covers serv msg. stat serv.. an you have to enl the card with a fdl, without that your changes are local, and do not go in effect. i did notice the mismatch des, but when you stat x in load 60 the correct d shows on your last port

I had the same problem one year ago.
Also follow the mluckie1 recomendation (Make sure that CLID table 0 is programed. Some carriers need to see all 10 digits). In my case the CISCO was waiting more digit and I was sending only four.

I see also that you are using A law in the trunk.
In the route you have TTBL=0. Can you see if the table have all tones and cadences for A law (LD 56).
The trunk have CLS DIP. Can you change to DTN.

For a best troubleshooting, enable the debug option in the CISCO for follow the process for a call.

Regards,
