Dear friend.

I have some problem when setting up BRI Interface (2B+D) in Vietnam.

This is my configuration:

end

Please help me to solve this problem.

I can't make call to PSTN.

Thanks all my friends.

Hi

The status of ISDN is not correct. it should be

MULTIPLE_FRAME_ESTABLISHED and not AWAITING_ESTABLISHMENT.

Check with your service provider and see what is the issue with D channel.

Dear Ronak Patel.

Thanks for your help?

So which command should be chaged? switch-type of ISDN?

Regards

[ronpatel]

Hi

I believe the switch type is correct. The  problem is with serivce provider. Please check with service provider.

Also send us the full router configuration.

HI

Why is your BRI0/1/0 interface is shutdown.  Do following

1) Un Shut the interface.

Try and remove below lin kcommand form the BRI0/1/0

2)  no isdn point-to-point-setup

3) isdn static-tei 0

Do clear counters and send out ut of router# show interfaces bri0/1/0 after doing one ISDN test call command.

Hi.

Interface was shutdown when I change switch-type. I forgot to up it

Hi.

For more information, I notice that BRI channel from PSTN have two port RJ-45 output through NT1.

When I connect a digital phone directly into NT1 output port, then the phone has signal (tone & display LCD up).

So can I use that port to connect to BRI interface? Is it different type between line use to connect phone and line to connect to BRI interface. This port is using to connect to SMTD3 card on Siemens HiPath 3800 and now I want to move it to Cisco 2921.

Best Regards.

Hi

what cable you are using to connect your BRI port with NT box.

Hi.

I use pin 3-6 to transmit and pin 4-5 to receive.

try

interface BRI0/1/0

no isdn static-tei

[Vinh Phan Le Tien]

Dear Paolo.

When I used command no isdn static-tei, Layer 2 status is Inactive.

Regards,

VinhPLT

[paolo bevilacqua]

Then static tei 0 is fine, now you try incoming and outgoing calls.

Note, unless you';re are familiar with CME already, the best approach is that you give the task to a reputable consultant, to avoid much loss of time and frustration.

[Vinh Phan Le Tien]

Dear Paolo.

I have configure at least 3 CME with FXO, E&M and E1 Interface. And this is used as a H.323 VG, not CME.

And this is the 1st time I try to use BRI Interface for 2B+D.

I connect it to PSTN through NT1.

But something maybe wrong. When I connect both of output RJ (one to Cisco and one to Siemens), you can see the result abow. When we unplugged Siemens port to NT1, BRI Interface was down. I don't know what happen with it.

Regards.

VinhPLT

[paolo bevilacqua]

With point-to-point BRI circuits (static-tei 0), you cannot have multiple devices connected to the NT1.

So you can only have the Cisco, or the PBX connected at one time. You can power off the NT1 to have it reset and recognize the new device connected.
