Re: Modem/ISDN dialin and TCP/IP forward, please help

Here's how you do what you're asking for, as far as the modem calls:

aaa new-model
aaa authentication login default local
aaa authorization exec default local

username 4321 nopassword dnis
username 4321 autocommand telnet 1.2.3.4 5555 /stream /quiet
username 1234 nopassword dnis
username 1234 autocommand telnet 1.2.3.5 4444 /stream /quiet

Debugs to use:

debug isdn q931
debug modem
debug aaa authorization
debug aaa authentication
debug ip tcp transaction

Use IOS 12.3(12.3) or above, due to CSCdw65197, CSCdz75649 and CSCef50626.

Now, as far as this X.31 Case A stuff ... that doesn't ring a bell with me.
If you want to have incoming ISDN data calls getting mapped to outbound
character mode TCP sessions, on this platform, you'll have to use the
following protocols:

V.110
V.120
"X.75" aka "LAPB-TA"

V.110 calls will appear on the TTY lines just like voiceband modem calls.
The V.120/X.75 calls will appear on VTYs.

Cheers,

Aaron

~ Dear all,
~
~ I have to configure a Cisco 3620 router to accept any calls which are
~ coming in via a PRI interface. The data shall then be sent via TCP/IP
~ to any host.
~
~ One TCP/IP connection per call is required. The TCP/IP connection shall
~ be closed if the line goes down and vice-versa.
~ Depending on the incoming MSN (or dialled number) a different TCP/IP
~ host and port shall be used.
~ The ISDN dial in uses X.31 case A (X.25 over ISDN B-Channel) and modem
~ uses V.22 bis MNP.
~
~ The router has following cards installed:
~
~ NM-1FEPRI2CE1-B/U
~ NM-30DM
~
~ I need some hints in order to find the right documentation. I don't
~ know the name of this "TCP/IP forward" or the specific IOS features
~ required.
~ ANY help greatly appreciated.
~
~ Best regards,
