[asterisk-users] PRI got event HDLC Abort

[Liban Abdi]

is there static on the line??
is there timing slips and crc4 errors?
are they increasing throughout the day?
are you getting timing slips during the day when users are using the phones
and not off-peak hours?
are you getting hdlc abort erros when you hear a static noises??

is the card sharing irq?
is your system plugged directly into an outlet without ups?
