In what order should I connect my Analog lines?

If you are connecting analog phone lines to your system, they should be connected in reverse hunting order. Your busiest incoming lines should be placed in your highest port numbers.

PBXtra dials out from the lowest port numbers first, so to avoid placing an outbound call while an inbound call is ringing this reverse order connection of your lines is essential.

On a PBXtra , the top PCI card is in PCI slot one. The next one down is in PCI slot two, and the third one down is PCI slot 3.  Each port on each PCI card has a port number stamped into the metal near the green LED. When you connect your phone lines to your PBXtra , connect them in reverse hunt order.  This order is explained below.  PBXtra places outbound calls on the lowest port number first.

Let’s assume you have the following six phone numbers from your phone company set up to hunt in order so that if one is busy it tries the next line:

1. 200-300-1001

2. 200-300-1002

3. 200-300-1003

4. 200-300-1004

5. 200-300-1005

6. 200-300-1006

In your PBXtra , you have six corresponding ports on two PCI cards as numbered below. (The port number stamped on the card is shown in parenthesis): 

Connect your phone lines in reverse order so that your busiest inbound line is connected to your highest port number. Example:

1. 200-300-1001 = LINE6 (Slot 2/Port 2)

2. 200-300-1002 = LINE5 (Slot 2/Port 1)

3. 200-300-1003 = LINE4 (Slot 1/Port 4)

4. 200-300-1004 = LINE3 (Slot 1/Port 3)

5. 200-300-1005 = LINE2 (Slot 1/Port 2)

6. 200-300-1006 = LINE1 (Slot 1/Port 1)

Using this line ordering, there is almost no chance that an inbound call and an outbound call will compete for the same port at the same time.
