Error
Code Description
8402 WINK TOO SHORT:
Outbound dialing problems on tie
trunks. Wink from the far end of
network interface is less than 100
ms, the minimum for delay-dial or
wink-start tie trunks. Tie trunk
waits for valid signal.
8403 NO EXTERNAL RELEASE:
Communication problems
between module and CO. Far end
has not disconnected within 4
minutes. If error occurs twice
consecutively, trunk is busied-out
automatically whether or not
automatic maintenance-busy is
enabled.
8404 ON HOOK BEFORE WINK:
Outbound dialing problems on tie
trunks. Far end of network
interface went on-hook before
handshake was completed (for
delay-dial or wink-start tie trunk).
8405 ON HOOK BEFORE READY:
Outbound dialing problems on tie
trunks. Far end of network
interface went on-hook before
guard time elapsed (for delay-dial
or wink-start tie trunk).
8406 INTERDIGIT TOO SHORT:
Inbound dialing problems on tie
and DID trunks.
8407 BAD UPDATE:
Communication problems
between processor and modules;
module may need to be replaced.
8408 ROTARY RATE > 12PPS:
Inbound dialing problems on tie
and did trunks.
8409 ROTARY RATE < 8PPS:
Inbound dialing problems on tie
and did trunks.
840A BAD DOWNLINK MESSAGE:
Communication problems
between processor and modules;
module received an unrecognized
message from processor.
