External Feature Access
Description
Allows the extension user to have access to the features of a host PBX, Centrex or Central
Office, such as Call Waiting, etc. This is performed by putting the current party on hold and
sending a flash signal to the other end during an outside call.
Conditions
• FLASH Button Operation
Pressing the FLASH button on a PT results in either sending Flash signal or disconnecting
the current call.
This is determined by System Programming <Section 2.8 System Option, "3. FLASH
button operation while CO talking" and "4. FLASH button operation when "Don't release
the trunk" is selected at #3" in the Programming Guide>.
• Flash Time
The flash time must be assigned as required by the Centrex, host PBX or CO line.
• Memory Dialing
During outside calls, a FLASH stored in System Speed Dialing, Station Speed Dialing or
One-Touch Dialing works as External Feature Access, not as Flash (Disconnect Signal)
used to disconnect the calls.
• <PT>
FLASH button or the feature number is used to perform this feature.
• <SLT>
Feature number is used to perform this feature. This feature does not function, if an SLT
has a call on Consultation Hold.
