Trunk Disable (DIS) LEDs
Two red LEDs indicate if the "trunk port 0" or "trunk port 1" portions of the card are disabled.
These LEDs are lit in the following cases:
• Upon reception of the "disable loop" message from the software.
• After power-up.
OOS LEDs
Two yellow LEDs indicate if the "trunk port 0" and "trunk port 1" portions of the card are out of
service.
NEA LEDs
Two yellow LEDs indicate if the near end detects absence of incoming signal or loss of
synchronization in "trunk port 0" or "trunk port 1" respectively. The near-end alarm causes a
far-end alarm signal to be transmitted to the far end.
FEA LEDs
Two yellow LEDs indicate if a far-end alarm is reported by the far end (usually in response to
a near-end alarm condition at the far end) on "trunk port 0" or "trunk port 1".
LBK LEDs
Two yellow LEDs indicate if a remote loopback test is being performed on trunk port 0 or trunk
port 1. The loopback indication is active when the digital trunk is in remote loopback mode.
Normal call processing is inhibited during the remote loopback test.
DCH LED
When the dual colored LED is red, it indicates the on-board DDCH is present but disabled.
When the dual colored LED is green, it indicates the on-board DDCH is present and enabled.
If a DDCH is not configured on the DDP2 card, this lamp is not lit.
