Considerations
•
If several calls arrive at a DSS/BLF key, the calls are queued and ring on a first-in, first-out basis.
•
If a BLF key has a second call while busy and off- hook signalling is enabled, the BLF key starts
blinking. The call can be answered by pressing the BLF key or going on hook and then off hook.
DIL Appearances
DIL keys are used to originate and receive calls over specific exchange line numbers (DIL keys can
be assigned to any exchange line number).
The LED for a DIL key will flash red on an incoming call even if the trunk is set to ring. If another
extension answers the call, the LED on the telephone will light solid red.

MCO Appearances
Description
You can make and receive trunk calls using an MCO key. Each extension can have up to 5 MCO keys.
An MCO key can be assigned to any of the pooled exchange line groups. Pressing the MCO key is the
same as dialling the MCO Access Code (usually
9 or 81-84
by default).
