Carlos,
You can see by the debug that the router is calling 3333000 in
order to bring up the second channel for PPP multilink and never calls
3333001.
00:39:09: BR0/0 DDR: Attempting to dial 3333000
00:39:12: BR0/0 DDR: Attempting to dial 3333000
Can you ensure that the Adtran is configured to support two
calls for the 3333000 number? This is under Dial Plan --> User Term -->
Ifce Config (select the number) --> SPID List --> Calls.
If the Adtran is configured to allow only one call for the
3333000 number, the router will of course not be able to connect two
calls using that number. If two calls are configured, the switch will
roll over the second call to the second channel.
