Help needed with ISDN setup on the service provider side ???

[ujjwalkumar18894]

I am setting up ISDN PRI connection with BRI connection. Need help with the configuration that needs to be done on the TELCO side. As we have the PRI connection with the TELCO and they want us to tell them the configuration that is required to set up the connection. We need to enable data transfer between the PRI and BRI connection. Somebody please help. I will be very grateful

Basically let them know how many digits they should pass to your pbx

Also what is the switch type you are using ni2 5ess etc

Here is the ISDN status of the PRI interface at the main office

DSCBL ISDN STATUS :

Global ISDN Switchtype = primary-net5

        dsl 0, interface ISDN Switchtype = primary-net5

    Layer 1 Status:

Also I am getting this error when trying to dial myself ( test calling oneself )

when test calling oneself :

debug isdn q931 is              ON.

DSCBL#isdn test call interface s1/0:15 23252112

        Cause i = 0x82B9 - Bearer capability not presently authorized

What is the problem and how to solve it from the TELCO side as i think there must be some problem with their configuration only.

Please help

Thanks in advance

2.      Are there any DID station numbers that your CPE cannot accept?   -

No

(i.e. 0 or 9 in the 4th position)

3.      Which carriers will be your choices for your PIC and LPIC?  -

Carrier using DChannel

4.      How many outpulse digits does the PBX need to receive?      -   10

ditit   e.i   11 + 8 nos.

5.      What type of signaling is needed? (wink, delay, or immediate)  -

immediate

6.      The default outpulsing is DTMF. Is this compatible with your CPE? (Y
