Ericsson F221m - Manual (Page 57)

Definitions
The following definitions are supplied in order to better
understand certain concepts included in this manual:
Switch-on: power up the FCT by connecting the AC
power supply or a charged battery.
Switch-off: power down the FCT by disconnecting
the AC power supply or removing the battery.
Fixed Line Devices: any analog devices that can be
connected to the analog fixed line:
• Fixed Telephones- ordinary telephones for the fixed
line
• G3 Faxes- ordinary fax machines available on the
market
• CLI devices- ordinary displays or telephones
equipped with displays that show the caller number
for incoming calls.
• V.90 modems- standard modems for PCs used to
make data connections (Internet) over the ordinary
fixed line.
Telephone Line: this is the line provided by the FCT
(RJ11 connector) that behaves in the same way as the
ordinary fixed line.
Telephone Line Wiring: this is the cable layout that
has to be available in order to distribute telephone
lines within a house or office.
GPRS: General Packed Radio Service. This is a
technology for data communications that is ideal for
e-mail or Internet access as it provides a high speed
“always online” connection. This means that,
although you are always attached to the network, you
only pay for the amount of data that you really
transmit.
PIN: Personal Identity Number. This is the number
you get from your network operator and which you
need to access the network. It will prevent the
SIM card to be used by unauthorized people.
PUK: Personal Unblocking Key. This is the number
you get from your network operator and which is
used to unblock your SIM card if an incorrect PIN
has been entered three times in a row.
SIM card: this is the card provided by your network
operator that you need to insert in your GSM terminal
in order to make and receive calls. It contains all the
information from your subscription characteristics.
