NQC

The NQC lamp, which is associated with the Number of Queued Calls (NQC) button, indicates that calls are in queue and that the number of calls in queue has met or exceeded the assigned queue threshold. If no calls are in the split queue, the status lamp associated with the button is dark. When more than one call is in queue, the lamp lights steadily. When the number of calls in queue reaches the assigned queue threshold, the lamp flashes on and off.

OQT

The OQT lamp, which is associated with the Oldest Queued Time (OQT) button, indicates that calls are in queue and that the oldest call in the queue has been waiting longer than the assigned wait time threshold of 0 to 999 seconds. If no calls are in the split queue, the status lamp is dark. When calls are in queue, the lamp lights steadily. When the assigned wait time threshold has been met or exceeded, the lamp flashes on and off.

Auxiliary queue status lamps

An auxiliary queue status lamp indicates that either the NQC or the OQT threshold is reached. The lamp lights when the assigned threshold is met or exceeded. Unlike the lamps on a phone, the auxiliary queue status lamp does not indicate when calls queue to the split.
