PLUG AND PLAY PHONE LINE MANAGER XL

4. Operation

4.1 Incoming Calls

Incoming calls to the first LINE Ports of the Plug and Play Phone Line
Manager XL are passed directly through to the Incoming IST Ports.
Therefore, the number of IST devices that can accept incoming calls is equal
to the number of telephone lines connected to the Plug and Play Phone Line
Manager XL. Example: four IST devices (Ports 1 through 4) can receive
incoming calls if four telephone lines are connected to the Plug and Play
Phone Line Manager XL.
Incoming calls to an Incoming IST port that is busy will forward to the next
available Incoming IST Port if the hunt enable switches for those lines are in
the "ON" position. Remember there must be at least two or more consecutive
hunt enable switches set to the "ON" position to create a loop or pool.
When a Line Port is ringing an IST Port, the Line Port LED (representing the
Line Port the call is coming in on) and the IST Port LED (representing the
IST Port that the Line Port is directly connected to) will both light solid and
the IST device will ring until answered or indefinitely until the originating
party hangs up. Once answered, both the Line Port and IST Port LEDs will
remain on throughout the duration of the call. If the IST Port is currently
busy with a call on another line, the outside originating caller (into the Plug
and Play Phone Line Manager XL) will receive a ring-back signal until the
intended IST Port does become available and answers. If the "Hunt Enable
Switch" parameter for the intended IST Port is set to ON, then the ringing
will be passed to the next Primary IST Port and that IST Port's LED will light.
When the IST device hangs up (goes on-hook) and terminates the incoming
call, the IST Port LED will go out immediately (upon sensing the IST on-
hook) and the Line Port LED will flash for up to 15 seconds to allow the line
to stabilize and the telephone company to release the line before allowing
another IST Port to select the line for an outgoing connection. If a second
incoming call comes in on the same line before the end of the 15 second
timeout, the Plug and Play Phone Line Manager XL will accept and process
the call.
