ISDN LAYER 3 PROBLEMS

Hi there,

I'm trying to establish connectivity from a 3600 router to a 2600 I can see layers 1,2 establish ok but a debug on the far en router shows the following

02:47:32: Low Layer Compat i = 0x8890

02:47:32: ISDN BR0/0: llc valid, speed 64, call type is DATA

speed:0 async:N

02:47:32: ISDN BR0/0: Event: Received a DATA call from <unknown> on B2 at 64 Kb/

s

02:47:32: ISDN BR0/0: Event: Accepting the call id 0x43

02:47:32: %DIALER-6-BIND: Interface BR0/0:2 bound to profile Di1

02:47:137438954155: %LINK-3-UPDOWN: Interface BRI0/0:2, changed state to up

02:47:32: ISDN BR0/0: TX -> CALL_PROC pd = 8 callref = 0x9F

02:47:32: Channel ID i = 0x8A

02:47:32: ISDN BR0/0: TX -> CONNECT pd = 8 callref = 0x9F

02:47:32: ISDN BR0/0: RX <- CONNECT_ACK pd = 8 callref = 0x1F

02:47:137438953472: %ISDN-6-CONNECT: Interface BRI0/0:2 is now connected to <unk

nown phone number> RXXXX-XXXXX2

02:47:32: ISDN BR0/0: TX -> DISCONNECT pd = 8 callref = 0x9F

02:47:32: Cause i = 0x8090 - Normal call clearing

02:47:32: ISDN BR0/0: RX <- RELEASE pd = 8 callref = 0x1F

02:47:32: Cause i = 0x8290 - Normal call clearing

02:47:32: Display i = '*AA*CLEARED#'

02:47:32: %LINK-3-UPDOWN: Interface BRI0/0:2, changed state to down

02:47:32: %DIALER-6-UNBIND: Interface BR0/0:2 unbound from profile Di1

02:47:32: ISDN BR0/0: TX -> RELEASE_COMP pd = 8 callref = 0x9F

Can anyone shed some light on what the problem might be ????

Thanks

Re: ISDN LAYER 3 PROBLEMS

Post the output of "debug ppp authentication". One side may be rejecting the other due to an authentication issue, and an ISDN trace would show this as normal call clearing.
