HAPTER EVICE ONFIGURATION
Off — POST test is running. The test runs approximately 5-seconds
after you apply power to the board. After 5-seconds, Off indicates the
POST test failed.
Green — POST test completed successfully.
DCH — D channel status of an ISDN PRI connection
Off — No E1 line is attached.
Green — Card is configured for ISDN PRI operation and an active PRI
connection has been established.
Amber — The D channel has not yet been established. It can take
several seconds after the card has completed its power up tests for the
card to establish a connection with the PRI trunk. If the DCH light goes
to amber after the connection has been established, it can mean that
an active control channel connection through the PRI line has been
lost.
DNLD — Download
Flash — The card is downloading software from the NBX Network Call
Processor.
Green — The download has been completed.
Amber — The download was interrupted before it completed.
On a LAN, the download process completes quickly. If the download
from NCP to digital line card must travel a routed network path, the
download may take a few minutes. If the DNLD light remains amber, it
can indicate a severely congested network or a hardware problem
with the card.
CALL — Call audio traffic
Off — No audio traffic on the link.
Flashing — Audio traffic is present.
CARD — Card Software Status.
Green — The card has finished downloading software from the NCP
and all software processes have started successfully.
Amber — A problem with one or more of the software processes
running on the card. The card automatically reboots itself if it detects
a problem with any of its software processes.
DSP — Reserved for future use.
NCP — Network Call Processor communications status.
