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 signaling 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.
Direct Line Appearances
Direct Line (DL) keys are used to originate and receive calls over specific trunk numbers (DL keys
can be assigned to any trunk number).
The LED for a DL key will flash red on an incoming call even if the CO line is set to ring. If another
extension answers the call, the LED on the telephone will light solid red.

You can make and receive CO line calls using a Multi-CO (MCO) key. Each extension can have up to
5 MCO keys.
An MCO key can be assigned to any of the pooled trunk groups. Pressing the MCO key is the same as
dialing the MCO Access Code (usually 9, 81-84).
