Troubleshooting
ISDN BRI interface problems
Pipeline User’s Guide Preliminary January 30, 1998 D-9
If you are running multipoint (passive bus) on your switch, all of the ISDN
telephone cables must be wired straight through. If any of the cables are
wired to cross over, you will not be able to place calls.
2
Check that 100% termination is provided on each ISDN line.
3
Check whether you have correctly specified the SPIDs (Service Profile
Identifiers) in the Configure profile for each line.
If the SPIDs are not correctly specified, the line status might indicate No
Logical Link. Check with your system manager or carrier representative to
obtain the SPID or SPIDs for your line. You specify your SPIDs in the
Configure profile.
Bridge/router problems
The quality of the link is questionable
When running FTP (File Transfer Protocol), the data transfer rate appears in
bytes per second. Multiply this rate times 8 to get the bits per second. For
example, suppose that you are connected to Detroit on a 56-kbps B channel and
that FTP indicates a 5.8 Kbps data rate; in this case, the link is running at
5.8x8=46.8 kbps, or approximately 83% efficiency. Many factors can affect
efficiency, including the load on the FTP server, the round-trip delay, the overall
traffic between endpoints, and the link quality.
You can check link quality in the WAN Stat status menu, or by running a ping
between the same endpoints. Dropped packets hurt the link’s efficiency, as does
round-trip delay. Random round-trip delay indicates heavy traffic, a condition
that also drops the efficiency of the link.
The Pipeline hangs up after answering an IP call
To resolve this problem, follow these steps:
1
If you are running PPP, check that you have entered the proper passwords.
2
Check that Auth is set to PAP or CHAP.
3
If you are routing IP over PPP, check that the calling device gives its IP
address.
Some calling devices supply their names, but not their IP addresses.
However, you can derive an IP address if the calling device is listed in a local
