Explanation |
| Unplug all other telephones, answering
machines, fax machines, and alarm systems on the same line. |
Other telephone equipment on the same
line as your computer modem, may reduce the strength of your modem signal and/or introduce
error causing noise. |
| Move digital mobile telephones away
from your computer & modem. |
Digital mobile telephones can increase the
data error rate and reduce throughput speed. |
| If you have an external modem, check
the cable from your computer to the modem - look for dirty or bent connector pins. |
Poor quality, faulty or very long computer
cables connected to external modems can reduce your line speed. |
| Check telephone cable connections for
corrosion - look for powdery green deposits on cable connectors. |
Dirty/corroded telephone cable connections,
modem socket or socket on the wall, will introduce noise. They should be cleaned or
replaced. |
| Check the cable from your modem to
phone socket -replace poor quality or damaged cables particularly telephone extension
cables. |
-replace poor quality or damaged
cables particularly telephone extension cables. Poor quality or damaged cables can reduce
your modem signal strength and line speed. In extreme cases you may experience call
drop-outs. Try borrowing another cable or, if you are using an extension cable, consider
moving your computer closer to the phone socket - then re-check your line speed. |
| Test and repair services for telephone
equipment or extra sockets in your house/office may be charged on a Fee for Service basis. |
The Telstra network, and Telstra’s
responsibility for maintenance, extends to the Network Boundary Point - for basic
residential and business services this is normally the first phone point in the house or
office. |
| Contact your computer/modem supplier
or NetYP, if you need help with computer equipment or connecting cables. |
NetYP can help ( service charge can apply) |
| If you have trouble with call
drop-outs when connecting to NetYP, try setting a lower line speed by changing the
initialisation string sent to your modem by your computer. (For help contact your
computer/modem supplier or NetYP.) |
Call drop-outs can occur if a speed aggressive modem is "fixed" at a line speed which is too high. The
modem handshaking routine(a sound like static on the radio), is used to establish the best
line speed for the connection, starting at the highest possible speed and training down to
a lower speed if required. If your modem cannot change with your ISP’s equipment,
then you may not be able to connect to the Internet and your call may be disconnected. |
| Setting a lower line speed may improve
throughput speed - try different speed settings till you achieve maximum throughput speed. |
When you connect to your ISP the modem
handshaking routine determines the best line speed for that connection. Speed aggressive
modems tend to connect at the highest possible line speed even if error rates increase and
throughput decreases. Setting your modem to operate at a lower line speed may improve
throughput speed by reducing error rates. |
| Do not use Modem Properties section of
Windows 95/98 to change your line speed setting. |
Simply changing "Connection Speed"
in the "Modem Properties" section of Windows 95/98 does not usually change the
line speed of your modem connection. You must use the modem initialisation string. |
