En-bloc dialling
Also known as advance dialling. You can key in the number you wish to call
and make any necessary corrections. Then you can lift the handset or press
the speaker key.
Enhanced line
ISDN line that offers three features more than the standard line: call
deflection, advice of charge at the end of the call and T-Netbox.
Explicit call transfer (on ISDN telephone systems)
ECT. Subscriber A calls subscriber B, places the call on hold and calls
subscriber C. Instead of now all talking in a three-party conference, A now
transfers B to C and replaces the handset.
Exchange
A nodal point in the public telephone network. A distinction is made
between local exchanges and long-distance exchanges.
H
Hands-free talking
The hands-free system on a telephone enables you hear the caller via the
loudspeaker and talk to the caller via a built-in microphone without lifting the
handset. Other people in the room can therefore also take part in the call.
Holding calls
(Hold). Interrupting and restoring an existing call. In particular, this is useful
for consultation calls and toggling.
Hot key
This disables the telephone for all call numbers apart from one specific user-
defined number. When the handset is lifted and any key is pressed a call is
automatically made to the stored number. This is ideal for children who
cannot be relied on to dial correctly. Calls to the emergency services can still
be made. This function is available on Gigaset 3000/2000 Comfort handsets.
I
Internal calls
These are connections free of charge between the base station telephone
and handsets.
Internal ringer
Special signal tone on telephone systems to discriminate between internal
and external calls.
ISDN
Abbreviation for Integrated Services Digital Network. Integration can cover
telephone, fax and data transfer for example.
