CHAPTER 3: Installation
3.3 Setting the Switches
SW1 (and SW2 on the 8 x 24 model) on the front panel of the Plug and Play
Phone Line Manager XL must be set to identify the line connections and
operation as follows. Switches SW1-1 and SW1-5 correspond to Line 1,
switches SW1-2 and SW1-6 correspond to Line 2, etc. SW2 is configured
identically to SW1 on the Plug and Play Phone Line Manager XL 8 x 24, and
controls Lines 5 through 8.

The Line Present/Not Present settings determine which of the lines are
checked for purposes of
outgoing
line access. When a device connected to an
IST Port goes off-hook, the Plug and Play Phone Line Manager XL will search
for an available line. The Plug and Play Phone Line Manager XL always
searches the higher-numbered LINE Ports first. Example: If four lines are
connected to the Plug and Play Phone Line Manager XL, the Plug and Play
Phone Line Manager XL will check LINE Port 4 first, then LINE Port 3, then
LINE Port 2, etc. The only exception to this is the first IST Ports (those IST
Ports that have a corresponding line connected to them). Each of these IST
Ports checks its own” line first. Example: IST Port 2 checks for line availability
