Unusual ATM Trouble Conditions
Issue 1 May 2002
4-59
555-233-143
Swapped Routes, End System Identifiers, or
Fiber between a PPN and an EPN
Symptoms
■
An incorrectly connected EPN TN230X does not complete board insertion.
■
Dial tone is present for PPN’s end stations and for correctly connected
EPNs, but not for an affected EPN’s end stations.
■
Calls cannot be made between the PPN and correctly connected EPNs,
because talk paths cannot be routed correctly.
Diagnostics
The show switch circuit table command on the A500 shows VBR control
channels from the A500 port intended for the incorrectly connected EPN (but
actually connected logically or physically to the PPN) that should not exist.
Action
Correct the ATM addresses (or swap fibers) on the A500 between the incorrectly
connected PPN and EPN.
Swapped Routes, End System Identifiers, or Fiber
between two EPNs
Symptoms:
■
Every TN230X completes board insertion.
■
The PPN cold starts both incorrectly connected EPNs as usual.
■
Both EPNs log many
WRONG BOARD INSERTED
errors (use list
configuration all or display circuit-packs carrier), provided the EPNs
actually do have different boards configured in the same slots.
■
Some end stations may work if they are connected to the correct board in
the same slot on both EPNs. Otherwise, end stations on the PPN have dial
tone, while end stations on the EPNs do not.
■
Every A500 diagnostic command looks good.
