83 NT/MPRI – 6 Tips and Troubleshooting

In addition to destination-specific budgets, the configuration of

global thresholds also can be checked here. Check the “Monitor-

ing / Server Status” window.

The thresholds are listed. If the global threshold for the budget,

connection duration or the number of outgoing calls has been

reached, the corresponding value can be adjusted with the follow-

ing command: “Configuration / Server Settings / Thresholds”.

l Check whether the NT/MPRI is able to connect to the AVM Data

Call Center (ADC). Pre-configured call destinations are provided

for the network protocols TCP/IP and IPX. For instructions on set-

ting up these call destinations and adjusting the configuration if

necessary, please see the section “Test Connection with the AVM

Data Call Center” on page 29.

l If this connection is not successful, install the file transfer pro-

gram Connect32 on the Windows

XP/2000/NT computer and use

it to try connecting to the AVM Data Call Center (number:

+49 (0)30 / 39 98 43 00).

l With dial-up connections, the ISDN error messages 3303 and

3302 indicate a problem with your ISDN line. The ISDN error mes-

sage 3403 means that the service “data” is not enabled on your

ISDN line. In either case, contact your ISDN provider.

l If the problem is not being caused by your ISDN line, use the

NT/MPRI’s packet trace function to trace all PPP over ISDN negoti-

ation packets. To do this, set the “Layer” option to “ISDN-Control-

ler / Network Adapter” and select the desired call destination.

Then click the “REC.” button.

No ADSL Connection to the Internet.

Check the protocol binding of the second network adapter:

While a network adapter is responsible for connecting the NT/MPRI

computer with a local network, the other network adapter is used ex-

clusively for communication with the ADSL modem. The PPPoE (RFC

2516) protocol (included in the Service Wrapper) is used for this com-

munication. Because this protocol transmits the information required

for registration with the ADSL provider via the ADSL modem, this proto-

col must be bound to the network adapter responsible for communica-

tion with the ADSL modem. The protocol is bound automatically to this

network adapter during the NT/MPRI installation. No other protocol is
