5-58Unusual ATM trouble conditions
5
■ Dial tone is present on end stations on the PPN and on
correctly-connected EPNs, but no dial tone is present on the affected EPN
end stations.
■ Calls cannot be made between the PPN and the correctly connected
EPNs, because talk paths cannot be routed correctly.
Diagnostics
1. The
show switch circuittable
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
1. 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
■ All TN230Xs complete board insertion.
■ The PPN cold starts both incorrectly connected EPNs as usual.
■ Both EPNs log many
WRONG BOARD INSERTED
errors (use
list
configuration al
l or
display circuit-packs
<carrier>
) providing 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.
■ All A500 diagnostic commands look good.
Diagnostics
1. Check log for WRONG BOARD INSERTED errors (use list configuration all
or display circuit-packs
<carrier>
).
Action
1. Correct the ATM addresses (or swap fibers) on the A500 between the
incorrectly connected EPNs.
