ERR0057
Excess invalid input messages from digital sets. Every input message is
counted. When the total count reaches a limit, this error message will
be printed and the count is reset to zero. The TN printed is only the
TN that generated the last invalid message. Other TNs may have
generated earlier messages. If no faults are found on the reported unit
then investigate other cards.

Severity: Minor
I have replaced the digital line card, because several other phones on same card were going down. Now I have another digital card disabled, replaced that card too. Still getting ERR 57 code, Thanks for your support...
