PLUG AND PLAY PHONE LINE MANAGER XLO (OUTGOING ONLY)
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 XLO will search for an
available line. 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 XLO will search for
an available line. The Phone Line Manager always searches the higher-numbered
LINE Ports first. Example: If four (4) lines are connected to the Phone Line
Manager, the Phone Line Manager 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). These IST Ports check
their “own” line first. Example: IST Port 2 checks for line availability (dial tone) on
LINE Port 2 first. If LINE Port 2 is not available (another device is using it), the
Phone Line Manager will check LINE Port 4, then LINE Port 3, etc. If all lines are
in use, then the requesting IST Port will get no dial tone to indicate no line
available.
If a telephone line is connected to a LINE Port, the corresponding switch
should be in the “ON” position. Each “line present” switch is factory-set initially in
the “ON” position. If a LINE Port has no line connected to it, the “line present”
switch should be set to the “OFF” position.
3.3 Connecting the AC Adapter
Lastly, plug the supplied wall-mount AC adapter into a suitable electrical
receptacle, and plug the mini-plug into the power outlet receptacle on the back of
the Plug and Play Phone Line Manager XLO. To protect the Plug and Play Phone
Line Manager XLO from electrical surges and brownouts, we recommend that you
use an electrical surge protector.
The Plug and Play Phone Line Manager XLO will illuminate all the front-panel
LEDs to indicate a self-test, and will then leave the POWER LED illuminated if the
self-test is successful. If the POWER LED does not stay on (all the LEDs turn on
and then back off), remove power, check all your connections and re-apply power.
If the problem repeats, see the troubleshooting information at the end of this
document.
