38 CHAPTER 1: INTRODUCTION Green - POST test completed successfully. ■ DCH - D channel status of an ISDN PRI connection Off - No T1 or T1 PRI line is attached or the card does not need a D channel, such as when the card is running T1-robbed-bit. 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 is complete or the Power-On-Self-Test (POST) is running. Amber - The download was interrupted before it was completed. On a LAN, the download process runs quickly. If the download from NCP to digital line card must travel a routed network path, the download can take a few minutes. If the DNLD light remains amber, it can indicate a severely congested network or a hardware problem with the T1 card. ■ CALL - Call audio traffic Off - No audio traffic on the T1 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 Amber - The card is trying to establish contact with an NCP.

DCH
— D channel status of an ISDN PRI connection
Off — No T1 or T1 PRI line is attached or the card does not need a
D channel, such as when the card is running T1-robbed-bit.
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 is complete or the Power-On-Self-Test
(POST) is running.
Amber — The download was interrupted before it was completed.
On a LAN, the download process runs quickly. If the download
from NCP to digital line card must travel a routed network path,
the download can take a few minutes. If the DNLD light remains
amber, it can indicate a severely congested network or a hardware
problem with the T1 card.
