HomePNA Device |
| Q. |
What
is the difference between the "LINE" port (the lower one)
and the "HomePNA" port (the upper one) of each RJ11 phone
jack pair in HomeSW 1200 ? |
|
A.
|
The "LINE" port is for connection from PSTN or PBX.
The "HomePNA" port is for connection from HomePNA device,
e.g. HomePNA card, HomePNA converter, or HomePNA switch.
If you connect HomePNA device to "LINE" port, the HomePNA
device will fail to work because the noise filter function
of "LINE" port may filter out part of the HomePNA signal.
The "LINE" port is for PSTN/PBX connection only. But
digital PBX is not suggested to connect to HomePNA Switch
because it may interfere the operation of HomePNA Switch.

| Q. |
Could I connect two HomePNA
Switch together by phone line? |
| A. |
Yes. You can connect two HomePNA
Switch together by phone line. But you have to connect
to the "HomePNA" port (the upper one) on both switches. |
| Q. |
What is the transfer speed
and connection distance of the HomePNA connection for
the HomePNA Switch? |
| A. |
It is 1Mbps speed and 500 feet
distance maximum for each HomePNA 1.0 connection. But
the real transfer speed will depend on the quality of
the phone line. Cross-talk is always a problem on the
phone line. If the quality of phone line is too bad, the
HomePNA connection may become unstable and the performance
will also go down. But it is no problem for most of the
phone line. |
| Q. |
Will the HomePNA connection
work if the connection is longer than 500 feet? |
| A. |
We have ever tried the connection
up to 400 meters and the HomePNA connection still works.
But it depends on the quality of phone line. It is 500
feet maximum in HomePNA spec. It is not guaranty for over
spec connection. But you may try. |
| Q. |
What is "Power Level" and
"Threshold" in the console setup? When should I try to
tune their value? |
| A. |
"Power Level" is the power level
for transmitting data on phone line. "Threshold" is the
threshold for receiving data from phone line. They can
be set from value 1 to 10 and the default value is 5.
It is not the bigger value is better or the smaller value
is better, but depends on the phone line condition. The
default value is OK for most of the phone line conditions.
You may try different values. But it may be not so obvious
to affect the performance for some phone line conditions. |
| Q. |
Can I use network and make
phone call at the same time by HomePNA connection? |
| A. |
Yes. Because HomePNA use different
frequency from the phone call on the telephone line, they
can work at the same time on the same line. |
