Titolo: Problema con ATM/IMA

Salve,
ho un 3745 con IOS v.12.3(9) e modulo AIM-ATM con 4 interfacce.
So per certo, avendole provate su un altro router (un 3600, che aveva i 
vecchi moduli), che le linee funzionano.
Le singole interfacce ATM sono attive ma non riesco a far salire 
l'interfaccia IMA, come si puo' vedere da:
# sh ima int
Interface ATM0/IMA1 is down
        Group index is 17
        Ne state is insufficientLinks, failure status is insufficientLinksNe
    IMA Group Current Configuration:
        Tx/Rx minimum required links 1/1
        Maximum allowed diff delay is 50ms, Tx frame length 128
        Ne Tx clock mode CTC, configured timing reference link ATM0/0
        Test pattern procedure is disabled
    IMA Group Total Counters (time elapsed 0 seconds):
        0 Tx cells, 0 Rx cells
        5 Ne Failures, 2 Fe Failures, 1618 Unavail Secs

        ATM0/0   up                     active                 disabled
        ATM0/1   up                     active                 disabled
        ATM0/2   up                     active                 disabled
        ATM0/3   up                     active                 disabled
Qualcuno mi sa aiutare?

Peggio ancora, vanno giu' anche le ATM.

 Salve,
un [X-post] lo potevi mettere, mica siamo tutti mono lingua... ;)
Alex.

Se collego le stesse linee ad un 3600 con il vecchio modulo  NM-4T1-IMA, 
funzionano benissimo.

Sono particolarmente gentile e bravo con le traduzioni :-)
