Hi All...
I have a question... I remember reading somewhere that it was possible to
split two B channels of a BRI line between two routers. Here is my layout...
ISDN Network --> Adtran NT1 ACE --> S/T#1 --> Router1 S/T#2 --> Router2
Things work great if I config to have both B channels on one router, or have
just one B channel on one router. However when I split them, the first
router to boot contacts the ISDN switch and gets two TE assigned, even
though I have only one SPID config'ed on the BRI interface. When the second
router contacts the switch to get a TE it gets an error, TE not assigned,
terminal down state.
Here are the relivent configs and show outputs. Any ideas what is a miss
here?
TIA
