■Dial tone is present on end stations on the PPN and on
correctly-connec ted EPNs, but no dial tone is present on the affected EPN
end stations.
■Calls cannot be made b etween the PPN and the correctly connec ted
EPNs, because talk paths cannot b e routed correctly.
Diagnostics
1. The show switch circuittable command on the A500 shows VBR control
channels from the A500 port intend ed for the incorrectly-c onnected EPN
(but actually connec ted logically or p hysically to the PPN) that should not
exist.
Action
1. Correct the ATM addresses (or swap fibers) on the A500 b etween the
inco rrec tly-c onne cted PPN an d EPN.
Swapped Routes, End System Identifiers, or Fiber
between two EPNs
Symptoms
■All TN230Xs complete board insertio n.
■The PPN cold starts both incorrectly c onnected EPNs as usual.
■Both EPNs log many WRONG BOARD INSERTED errors (use list
configuration all or display circuit-packs

<carrier>

) providing the EPNs
actually do have different b oards 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 th e PPN have dial
tone, while end stations on the EPNs do not.
■All A500 diagnostic c ommands 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 b etween the
incorrectly connec ted EPNs.
