Glossary
Diversion Bypass
This is useful for letting urgent calls through to
an extension where diversion is active.
See section "Diversion".
Extension
All telephones connected to the PBX have a
unique internal number. If your telephone is
equipped with a display, you can see your number.
Forced release
Disconnecting a third (undesired) party during
intrusion. See section "Outgoing calls".
Function code
A digit code that corresponds to a specific
function. See section "Programming".
Group call
A group of extensions can have a common
number beside their individual extension
numbers. Any extension within the group can
answer the call.
Hold
To park a call. See section "During calls".
Identification
If an extension is busy, the operator can
identify the other conversation party.
Information
Internal callers are informed about absence and
time of return. External callers are diverted to
the operator, where the same information is
available. The operator can insert text or voice
information for any extension in the system.
This is useful for keeping the stored information
up-to-date for colleagues who are out of their
offices. Information can be of three kinds:
1. Pre-programmed text information.
2. Text information (only to display phones).
3. Voice information.
Intercom line
A two-way direct call function between two
extensions, for instance an executive-secretary
communication. See section "Other useful facilities".

Intrusion
To intrude on an ongoing call when a requested
extension is busy. See section "Outgoing calls".
ISDN
Integrated Services Digital Network. Provides
your system with supplementary services from
the public net. See section "ISDN facilities".
Least cost routing
A function that automatically selects the
cheapest way to connect your external call
(not necessarily the shortest distance).
See section "Least cost routing".
Loop keys
The operator can use the three loop keys to
supervise call progress when placing calls
with a free or a busy extension. A call that is
being placed or is put on hold via a loop key
can be retaken at any time.
Loudspeaker paging
All members of an extension group are
"paged", i.e. receive a short, sharp tone on
the loudspeaker followed by a voice message
from the sender. See section "Group facilities".
Mailbox
The mailbox system controls the messages
that are left for or sent by you when you are
absent. See section "Mailbox system".
Message
A message can be sent to any extension. This
is useful when you receive the busy tone or get
no answer. There are three kinds of message:
1."Call me" message.
2. Text message (only to a display phone).
3. Voice message.
See section "Internal messages".
Metering
Outgoing external calls can be metered on
individual call meters or specified account
numbers. See section "Call metering".
