I'm trying to setup an ISDN link between 2 cisco routers.  One is a 3640 with its on bri ports.  The other is a 3810 with an Adtran isu device connected to it.  The link is a backup in case the T1 goes down.  I can only get the 3640 to connect to the Adtran isu device for only 20 seconds.  Please help.  below is the config i have for the 3640.

Current configuration : 9991 bytes

 no fair-queue

dialer-list 1 protocol ip list 199

the adtran is configured through the front lcd interface.

the sh isdn stat shows:

        dsl 8, interface ISDN Switchtype = basic-ni

        TEI = 104, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
        TEI 104, ces = 1, state = 5(init)
            spid1 configured, no LDN, spid1 sent, spid1 valid
            Endpoint ID Info: epsf = 0, usid = 71, tid = 1

any help is greatly appreciated.

How do they authenticate ?
if they are connected and drops then i'd guess its an authentication problem

Does the Adtran require authentication?

If so...
Add the following to the BRI1/0 interface:
    ppp authentication chap
And modify the following:
    dialer map ip 172.16.255.5 name NYC_3810 speed 56 broadcast 19173680097

Also, I see the "dialer-list 1 protocol ip list 199" statement,
but don't see the "access-list 199 permit ip any any" statement.

the adtran does not require authentication.  from what i was told the authentication is done by the router that the adtran is connected to.  i have no authentication set on any of the routers....I made the suggested changes and this is what i get when i try to ping the remote router.
