Set the Error List to errors and Category to PNC on the input screen
(Figure 4-31), and press Enter to display any cause codes (see following
Table 4-6) returned from the ATM network to a TN230X on the PPN (and to
a TN230X on an EPN). This is successful only if the links between the
PPN and the EPN remain up so that the message from the EPN is logged.
Refer to ‘‘ATM-BCH (ATM B-Channel Trunk)’’ on page 8-168 for detailed
