Configured a new PRI2 Q.931 circuit for access to CO but there is a remote alarm on the card. IS that the reason why my DCH is not establishing a connection even if the trunks are idle?? Can I test this PRI2 on an existing working Q.931 trunk which is presently working on an MD110?

Also you need to verify that Telco has released thier end for you to bring in it up. If they are in some sort of maintenance I know I get that here when I try to bring my circuit up.
 

Ld96 DCH is "OPER RLS". Goes thru the AEST...SDCH...but does not establish.
Should the DCH not still come up even if clocking is disabled?? Can I test this circuit on a working Q931 link which is terminating on Md110?? Will I have to chge any config for this to work?
 
Dch IFC = D100. Is it Telco recomended?
How many timeslots configured in this physical link?
 
The Telco info given is Q9331 protocol used is ETSI PRI. But when I try to set my IFC-E403 to CNTY-ETSI I get SCH6232.
I am using NTAK79 card.
 
NTAK79 card does not support ETSI.
You need NTBK50 PRI with NTBK51 D-channel daughterboard.
 
Thanks guys, will get the necessary hardware. Pursued this bcuz tech at customer site said it worked before but he may have been misinformed.
 
You Need and NTBK50 plus NTBK51 (DCH Daughter card) plus a clock controller daughter if you don't already have one.

The CO version of etsi is E403 as you stated,

Cheers, Andy.
 
you also need a ntak20bd with the 51 daughterboard, these both go onto the ntbk50

Remember if it doesn't work hit it harder
