Can not dial out from ISDN Line with 1812j

[rojiroji123]

Hi, Now I am tring to setup Cisco 1812j with ISDN Line.

Here is what I connect the device.

(I am in Japan)

ISDN Line (NTT east) >> DSU(NTT east INS Mate V30Slim with S/T port) >> Cisco 1812j(S/T)

On DSU setting I enable DSU and Disable Terminator.

First of I would like to test outbound call.

Here is the config.

interface BRI0
ip address 192.168.92.2 255.255.255.0
encapsulation ppp
dialer map ip 192.168.92.1 name Router1 broadcast 080********(Cell Phone Number)
dialer-group 1
isdn switch-type ntt
isdn point-to-point-setup
ppp authentication chap
ppp chap password 0 CISCO

ip route 10.92.0.128 255.255.255.248 BRI0 192.168.92.1

Then I test by ping with #debug dialer.

#ping 10.92.0.129

And I could not receive a call by my cell phone landline either.

Here is the debug.

*Jan 12 09:47:02.077: BR0 DDR: place call
*Jan 12 09:47:02.077: BR0 DDR: Dialing cause ip (s=192.168.92.2, d=10.92.0.129)

*Jan 12 09:47:10.077: BR0 DDR: Attempting to dial 080*********Jan 12 09:47:10.077: BRI0: call delayed. number redialed too soon.
Success rate is 0 percent (0/5)

I can call from analog phone thru DSU.

But somehow I can not call from 1812j.

I am wondering where is the issue.

Thanks

Perhaps you need to add the following:

isdn sending-complete

This should be added under interface configuration.

Thanks, lgijssel

I tried that however it still same.

By the way,

Currently it does not light on B1 and B2 at front of the device.

Only "Link" is lighting.

Is this normal?

May be when ISDN connect to the other end it will light up?

Thanks

Other information.

#sh isdn status
Global ISDN Switchtype = ntt
ISDN BRI0 interface
        dsl 0, interface ISDN Switchtype = ntt
    Layer 1 Status:
        ACTIVE
    Layer 2 Status:
        TEI = 67, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
    Layer 3 Status:
        0 Active Layer 3 Call(s)
    Active dsl 0 CCBs = 0
    The Free Channel Mask:  0x80000003
    Total Allocated ISDN CCBs = 0

Looks ok?

Probably yes.

Can you post the output for "debug isdn events"

Here is the debug log.

I turn on debug dialer and debug isdn event.

I think I may be find the issue.

I was testing the line by calling to my cellphone.

But ISDN does not allow to call as voice as data.

Now I test calling to the other landline number which connect with other ISDN Router,

The debug log is not same as what I call to cell phone as below.

*Jan 13 05:54:28.211: BR0 DDR: place call
*Jan 13 05:54:28.211: BR0 DDR: Dialing cause ip (s=192.168.92.2, d=10.92.0.129)
*Jan 13 05:54:28.211: BR0 DDR: Attempting to dial 03********.
*Jan 13 05:54:30.143: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to 03******* N/A.

I am going to setup the other ISDN Router.

Hopefully works.

By the way,

How can I test the line connectivity if I only have one ISDN Router?

May be #show isdn status?

Thanks

[lgijssel · Accepted solution]

With one router, you can only verify the connection to the isdn network but perhaps this is also what you mean?

To verify the connection, you need to see return traffic from the network.

What I used to do was turning on "debug isdn q931" and toggle the line. (shut-no shut)

Then check the output for two-way communication.

Thanks Leo.

It works now.

The problem was CHAP username was wrong.

I just change the username to same name as hostname.

http://www.cisco.com/en/US/tech/tk713/tk507/technologies_tech_note09186a00800b4130.shtml

debug isdn q931

and

debug ppp authentication

debug ppp negociation

Those command helps me.

Thanks
