4. Look at the attribute values of the following MIB objects:

• wfIsdnSwitchCfgEntry

• wfPppCircuitEntry

• wfSwservOptsEntry

• wfPppLineEntry

• wfIsdnBriInterfaceEntry

• wfPppWhoamiEntry

• wfSwservOutPhoneNumEntry

• wfIsdnLocalPhoneNumEntry

• wfIsdnPoolEntry

• wfIsdnCallInfoEntry

If a call fails, do the following:

1. Verify that a line is available from a pool to make a call.

2. Verify that a call setup is in the log and that the calling and called

number are correct.

3. If the ISDN connection is present, ﬁlter the PPP event messages to verify

that the PPP negotiation succeeded. To do this from the Technician

Interface, enter

log -ePPP -ffdwit

Verify that the CHAP (Challenge Handshake Authentication Protocol) or

PAP (Password Authentication Protocol) data in the wfSwservOptsEntry

matches that of the remote router’s wfPppWhoamiEntry.

If it is CHAP, make sure the Secret is identical on both sides of the link.

5. Verify that the protocol network numbers and adjacent host information

are correct.

6. If using call screening on incoming calls, verify that the numbers in the

Dialup➔Incoming Phone Numbers table match those in the Call Setup

messages received.
