Description and Installation
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.
