MODEM INSTALLATION - SINGLE PHONE SOCKET
Incoming Line |
To use the IDSL Modem, it must be connected directly to the telephone
exchange, via the incoming line.
The original telephone line, back to the exchange, will carry digital
signals after the IDSL Modem is installed. The line will then be referred to
as a digital subscriber line or DSL.
|
Single Socket |
If you have only a single telephone, located adjacent to the required
computer/data facility, and there is no more wiring beyond this
point, then no modification of the house wiring is necessary.
Installation is accomplished by simply unplugging the telephone,
connecting the modem to the vacated socket, with the supplied cable, and
plugging the telephone into the Phone port of the modem.
|
Modem Connections |
All connections to the IDSL MODEM are made via sockets on the back
panel.
- Connect the RJ-45 (DSL / Telephony combined port) to the wall
mounted (country specific) socket using the 3m cable provided.
- Connect the female DB9 connector (RS-232 interface, V.24 data port)
to the serial port (COM port) of the PC, using the supplied cable.
- Connect a desk phone to the RJ-11 socket, if required.
- Connect the low voltage dc output of the mains adapter to the 2.5mm
power socket (centre positive).

MODEM CONNECTION SCHEMATIC
Telephone Service During Installation
|
If the modem is installed prior to the LT (its companion exchange
equipment) but not powered up, metallic bypass circuits will preserve the
connection from the telephone to the incoming line. |
Cordless Telephones |
If a cordless telephone is used, it should be located at least 3m from
the modem.
|
Earthing (Grounding) |
The IDSL MODEM is designed to operate without a local earth connection.
Do not earth the IDSL MODEM.
|
Mains Power |
The modem must be powered from the local mains, using the supplied plug
top adapter. The mains outlet should not be shared by other equipment,
which might generate mains-born RF interference. This would include such
equipment as TV sets, microwave ovens, Ham Radio transceivers etc.
|
Market Specific Power Adapter |
Check that the power adapter supplied with the IDSL MODEM is correctly
rated for the voltage and frequency of the local mains supply.
Use of a non-approved power supply will negate the equipment
warranty.
