If you have a question about your NetBlazer, first check the installation
chapter (Chapter 2, “NetBlazer LS Installation”) to make sure the NetBlazer
is installed correctly. Then check the tables on the previous pages to see if
there is a known solution to your problem.
Your BRI port is not
communicating
successfully with your
phone company’s ISDN
switch.
Try one of the following solutions:
1. Make sure you are using the full 8-wire RJ-45 phone cable that
came with your NetBlazer for the connection between the NetBlazer
and the NT1.
2. Exit from the Setup Utility and log on to the NetBlazer as root. Type
line list bri XXX (where XXX is the number of your bri line, such as
011 or 012). Check to see if ISDN Layer 1 shows F7: Activated. If
not, there is a problem with the physical connection. ISDN will not
work on the NetBlazer until Layer 1 is in state F7.
3. Make sure your ISDN line has been configured by your provider for
point-to-point, not multi-drop.
4. Make sure you have configured the NetBlazer for the correct ISDN
switch type. (If the switch needs to be changed and the NetBlazer
was already connected to an active ISDN line, then change the
switch settings, save your configuration, and reboot the NetBlazer.)
Note that the NetBlazer defaults to a 5ESSB switch type.
5. If your Service Provider’s CO (Central Office) has a DMS100 or NI1
switch, make sure you have your SPID set to the correct number. If
you have a DMS100 switch, make sure your DN is correct.
If everything is set correctly within the Setup Utility, but you suspect
a problem with the SPID or DN, exit the Setup Utility and log on as
root. Type line list briXXX (where XXX is the number of your bri
line, such as 011 or 012). The list displayed will indicate if the SPIDs
have been registered. If the SPIDs have not been registered, type
line reset bri011 port to reset both B-channels.
6. Verify that the NetBlazer is the only TE1(Terminal Equipment 1)
device attached to the NT1.
